RadioLINK benefits – briefly

• The installation time is greatly reduced. You don’t need to lift the floorboards and the carpets, and the level of user disruption is minimum.
• The “Easi-Fit” technology applied/incorporated saves further time and money on every installation of the fire/smoke/heat alarms.
• These alarms have a wireless interconnection(no need to hard-wire their connection) and a zoning capability(you can plan/divide the house into zones, assigning each alarm to a zone);
• The interconnection cost is fixed, actually it is included in the cost of the devices;
• The radio transceiver technology used has been tried, tested and proven for a while now;
• This system is fully upgradeable – future proof fire alarm system;
• The risk of accidental mis-wiring is minimal;
• False alarms – no false alarms from normal electrical transients;
• The usage of the Easi-Fit alarms has proven to be an excellent idea in millions of installation nationwide;
• There is a wide range of optional devices available:
  - The remote control switch(Ei411H) – only for use with the Ei160RC series(the Ei161RC, Ei164RC, and Ei166RC models);
  - the Manual call point Ei407;
  - The relay module Ei428;
  - The alarm for the deaf Ei170RF.

So, why not save time, trouble, and money with the Aico RadioLINK devices!

RadioLINK – wireless interconnection of the smoke/heat alarms

RadioLINK is the only mains-powered smoke and heat alarm system that interconnects not via hard-wiring but via a radio signal(not cable wiring but wireless). What you need to do is to simply install each alarm with an Aico Ei168RC RadioLINK base and then wire them to the nearest light fitting. Activate the House-Code switch on each of the units in the system – now all the alarms on the system will sound if any one of them detects fire! They are inter-connected via the RadioLINK technology.

Major Time Savings with RadioLINK
Because there is no need to run cables and fix them in the walls/ceilings, causing a good mess in the process, you can complete the installation in a fraction of time! All you need to do is to just connect / wire the heat/smoke alarm to the nearest light fitting for power supply.

RadioLINK – in conjunction with EasiFit
This wireless interconnection technology, RadioLINK, features the unique and patented Easi-Fit installation system that has been widely positively received and acclaimed by the contractors and domestic installers. This way of installing the fire / smoke / heat alarms ensures that you save even more time on every installation.

Ideal for Larger Systems and HMO’s
With RadioLINK, a larger alarm system can be installed easily quickly, with a minimum disruption. This wireless technology of interconnecting the fire alarms also allows simple alarm zoning and setup as optional ancillary devices such as the manual call points, the remote signalling relays, etc.

Special Needs compatible
The RadioLINK technology and devices can also meet additional system requirements very simply and easily – whether it is providing warning for deaf persons (see Aico Ei170RF), installing a relay (see Aico Ei428) to signal to a Warden Call System, or providing a switch (see Aico Ei411H) to control a system without having to climb on a chair to access the alarms.

Unique House Coding
The RadioLINK units have a simple and unique coding system for the use of installation. The activating of the House-Code switch on all the units allows the RadioLINK alarms to automatically “learn” each other as a system – they automatically detect one another and coordinate together. This eliminates the risk of interference from the neighbouring systems.

The Multiple Repeater Function
The Ei168RC RadioLINK base unit now features a multiple repeater function as standard – this allows the radio signals to trave aling multiple paths. This multiple path capability allows the system to manage many RF impenetrable structures in the property, providing a more robust and reliable interconnection between all alarms in the system.

A Proven Technology
The RadioLINK technology has been developed, designed, and manufactured by Ei Electronics – the first name in domestic fire safety for quality, performance, and reliability. This radio technology incorporated in the RadioLINK base is already widely proven in literally thousands of domestic applications, while the detection element consists of the best-selling Aico Ei160RC series or the Aico Ei140 series alarms – the most successful and popular designs in use today.

Planning for the future – future proof
With this wireless technology from Aico, it is exceptionally fast, simple and cost-effective to change or add alarms and ancillary devices. If the requirements change, a RadioLINK system can be adapted easily to meet the new requirements.

When installing a mains powered smoke alarm system, how much time do u waste? With the Aico Easi-Fit installation system incorporated in the RadioLINK devices, you don’t have to:

• remove carpets – interconnecting the smoke alarms is vital, but it can also be consuming, highly disruptive and often damaging to the property. It does not have to be so, in a normal way! Easi-Fit solves that problem! No Removing of the Carpets!
• lift the floorboards – you may need to channel into walls, rip up and then replace floorboards, install obtrusive trunking, make good any plaster damage, replace damaged wallpaper, repaint the surfaces, or even re-lay the carpets. The preparation and repair work can add hours to an installation. The Easi-Fit technology does not make this kind of mess/require you to go through this trouble! No Lifting Of The Floorboards!
• have unsightly trunking – No Unsightly Trunking! You can now install a high quality mains powered alarm system in a small fraction of the normal time – and in the same time avoid all the mess, expense and time wasted with hard-wired interconnection – thanks to the RadioLINK technology!

You can overcome all these troubles with the RadioLINK technology!

Also, more details about the Easi-Fit technology can be found here. To help you in your choice of the domestic fire alarms, we also recommend the Domestic alarm selector, choosing what alarms to fit and where, based on BS 5839-6:2004.

• The responsible person is required under BS5839 to undertake certain tasks with respect to the testing and maintenance of the Fire Alarm System.
• The responsible person is also required to liaise with the building maintenance personnel to ensure that their work does not impair or otherwise affect the operation of the Fire Alarm System, and to ensure that a clear space is maintained in the vicinity of detectors, and call points (break glass units) remain unobstructed and conspicuous.

Routine Testing

• The responsible person should also ensure that the following routine testing is carried out. If there is a link to a remote monitoring centre it will be necessary to advise the centre prior to a test.
• On larger systems it may be necessary to isolate building services interfaces to avoid disruption to the occupants.
• In any case the panel should provide audible and visual indication that parts of the system are isolated. This may take the form of a light on the main control panel.

Daily testing
Check that the panel indicates normal operation and that any fault is recorded. Also check that the recorded faults have been dealt with.

Weekly testing
Every week, a different Manual Call Point should be operated to test the ability of the control equipment to receive a signal and sound the alarm. The results should be recorded in a log book.

Biannually (previously quarterly) testing
The system should be checked by a Fire Alarm service organisation. This may be the system installer or an approved maintenance company, and is normally arranged via a maintenance agreement which specifies the number of visits and the level of service. The agreement should also cover non-maintenance visits, eg. call outs to attend faults etc.

The standard specifies a number of maintenance tasks which include a visual inspection of the installation to ensure that there are no alterations or obstructions which could effect the operation of the system, and functional checks to confirm the operation of the system. Any defects should be recorded in the log book and reported to a responsible person. A certificate of testing should also be completed and given to the responsible person.

Annually testing

• Each device on the system should be tested for correct operation as before.
• Any defects should be recorded in the log book and reported to the responsible person.
• A certificate of testing should be completed and given to the responsible person.

Action by user following a fire

• Advise the servicing company to arrange for the system to be tested by them.
• A certificate of testing should be issued to confirm the system operation following the inspection and any remedial work that is necessary.

Action by the user after any false alarm

The user can assist the servicing company in the identification of false alarms by observing the following:

• Always make a note of all illuminated indicators and messages displayed at the control panel
• Try and identify the activated device, i.e. Do not reset the panel until the area of the incident has been inspected
• Record any other incidents occurring at the same time which could affect the system, e.g. Power supply failure, building works etc.
• The service organization will be more likely to trace the false alarm if the above information is available.

Action by the user following a fault

• When a fault is reported by the control panel, the user should note all illuminated LED’s and the circumstances at the time the fault occurred, and report to the servicing company.
• The service company will be able to advise if the system is still able to respond to a Fire Alarm or whether extra vigilance should be observed until the fault is rectified.
• Faults should, under no circumstances be left unreported.

These are the generally accepted guidelines by Rafiki, Aico, and other Fire Alarms manufacturers, and they are also commonly accepted for all the domestic, commercial and industrial properties in UK. It is also our recommendation to all our visitors and customers to mind these basic rules(which should also be printed/posted especially at the workplaces).  Read more about the Rafiki advices for Fire Alarms, some of the guidelines provided by Rafiki(intelligent fire technology) – check out the Rafiki series of industrial/commercial fire alarm systems (like the Rafiki Twinflex), found at The Conventional and Analogue Fire Alarms. For more details about the fire alarms, visit the Fire-Detect website(see a list of articles about the fire alarms here and here).

• Are you Installing the smoke alarms from Aico?
• Are you confused?
• Are there too many conflicting views?
• Here is the 17th Edition Myth Exploded! – the 17th edition myth related to the smoke and heat alarms (the pdf file)

• The Smoke alarms can be connected to a lighting circuit – this is the preferred  circuit.
• The alternative is wiring on a dedicated circuit.

Who says this?

• Most reputable smoke alarm manufacturers.
• The IEE, NICEIC, ECA or SELECT.

What does the 17th edition say?

The 17th edition does not make any reference to domestic smoke alarm installations in the whole document.

Why are some manufacturers saying that smoke alarms should be wired on a dedicated circuit?

They are misinterpreting the requirements of Chapter 56 – Safety Services. This makes reference to fire detection and alarm systems, but in section 560.10 it refers you to BS 5839 for the specific requirements. Appendix A makes it quite clear that BS 5839: Pt. 1 is the document being referred to. This standard is for commercial systems, it is not the standard for domestic smoke alarms systems, this is BS 5839: Pt. 6.

I’m confused: what should I do?

In the absence of specific advice in the 17th Edition for domestic smoke alarm systems to Grade D(mains with a back-up battery), follow the recommendations of BS 5839: Pt.6.

What are these recommendations exactly?

Clause 15.5 states that Grade D smoke alarms can be wired from either…

• ‘An independent circuit at the dwellings main distribution board, in which case no other electrical equipment should be connected to this circuit’.
• Or ‘A separately electrically protected, regularly used lighting circuit’.
• Note that RCD protection is not mentioned. Therefore, an RCD protected circuit is acceptable.
• Hard-wired systems must be on a single final circuit.
• Radio-Linked systems must be on a single final circuit.
• Radio-Linked systems can be on separate lighting circuits.

For any more advice, call and talk to the IEE, NICEIC, ECA or SELECT. Read/print the above details as a flyer from Aico – pdf file.

34. Why choose Aico Ei Professional Smoke Alarms?

17. What cable do I need for the Aico Mains connections and where should the supply be taken from?

Fitting

We recommend the use of 6243Y 3 core and earth PVC insulated cable to BS6004 standard. Building Regulations and BS 5839: Pt 6 state that mains only alarms with back-up, can be wired from a dedicated circuit at the distribution board, or they can be wired from a regularly used lighting circuit. In both cases, all hard wired alarms should be on a single final circuit.

18. What cable do I need for the interconnect line?

Use the third core of 6243Y cable as stated above. Do NOT use the earth wire of twin and earth cable as this could cause problems of mistaken identity at a later date.

19. How do I mount the Aico Alarms on the ceiling?

The Aico Ei140 and Aico Ei160 series Smoke and Heat Alarms have an Easi-fit mounting plate,which incorporates an enclosure for the electrical connections, so no back box or mounting kit would normally be required.

20. Can I fit the Aico Smoke or the Aico Heat Alarm on the wall?

All of the Aico Ei alarms are designed for ceiling mounting and will under most circumstances perform better if sited in this position. If it really is not practical to mount them on the ceiling, a Smoke Alarm can be wall mounted with the top edge 15-30cm from the ceiling. Ensure that it is 30cm away from any corner or obstruction which may impede the movement of smoke to the alarm. Do not wall mount heat alarms.

21. How many Smoke and Heat Alarms can I link together?

We recommend that under normal circumstances Smoke and Heat Alarms should only be interconnected within the confines of a single family dwelling. If they are connected between different units, there may be excessive nuisance alarms and it can be difficult to locate and silence the unit causing the alarm. However, there is no technical reason why up to 20 alarms cannot be interconnected in a single system that encompasses a number of individual dwellings – such as may be required in an HMO, for instance. In circumstances such as these, a very high level of system design, management and maintenance is necessary to reduce the level of nuisance alarm.

The minimum requirement should be to install a System Remote Control Switch Ei1529RC on each floor of the property. By pressing the locate switch, all alarms in the system are silenced, for a period of approx. 8 – 10 minutes, except for the unit initiating the alarm state. This allows time to rectify the problem before the system is automatically reinstated to full working order.

22. Can I use a relay to signal other devices?

There are a number of options available for using a relay with Aico Ei Smoke and Heat Alarms. All the relays have volt-free output contacts rated at up to 240V and have both Normally Open and Normally Closed connections. There are relay options available for use with mains operated devices such as bells, sounders and door closers. In addition, there are relays available with a battery back-up for use with devices that will operate even in the event of a mains failure, such as Warden Call Systems. The relay can be mounted under an alarm, or can be remotely sited using the optional cover for electrical safety.

23. Can I use the relay to connect to a 24 Volt Fire Alarm System?

Technically it can be used but if the system has to comply to BS 5839: Pt 1 it may not meet all the requirements. For example, it is not possible to silence the sounder in the smoke alarm from the control panel. Many regulatory bodies now recognise that a dual system (smoke/heat alarms in the individual occupancies and a Pt.1 system in the communal areas) in HMOs can be an extremely effective means of reducing the incidence of false alarms. In this instance, subject to approval, it could be an advantage to have this link.

24. How often should they be tested?

Maintenance
We recommend weekly testing by pressing the test button on the alarm/s for between 5 – 10 seconds, or until all interconnected alarms sound. The use of a low level System Control Switch sited at low level can be used to make this easier for the occupier.

25. Should they be tested with smoke/heat?

BS 5839: Pt.6: 2004 recommends that a smoke/heat test is preformed when the system is commissioned. Pressing the test button checks the electronics, interconnect and the horn are operational, so it is our view that it is not necessary to test with smoke or heat and a ‘variation’ can be invoked in order to comply with the standard. However, if it is considered that testing of smoke alarms is a necessity, we would only recommend the use of special purpose built equipment such as the SAT332 Smoke Alarm Tester with the SAA300 Synthetic Smoke Aerosol. This device ensures that sufficient synthetic ”smoke” enters the sensor chamber and remains long enough for the Smoke Alarm to respond. Other methods of smoke testing, e.g. a lighted taper or smoke pellets, can give misleading results. Testers for Heat Alarms are also available. Do Not test with a flame – this can be a hazard in itself.

26. What maintenance schedule is recommended?

The Aico Ei range of Smoke Alarms and Heat Alarms are suitable for use in Grades D, E and F systems as defined in the British Standard which covers alarm systems in domestic dwellings, BS 5839: Pt6: 2004. It states that these alarms “should be cleaned periodically in accordance with the manufacturers instructions”.
Our recommendations are as follows:

• Regularly check to see that the green mains power light is on.
• Press the test button weekly to check all alarms in the system.
• Regularly check that the red light under the test button or on the cover flashes approx. every 40 seconds.
• Clean the cover of the alarm regularly using a barely damp, lint free cloth.
• On a monthly basis (at least) check the alarm for signs of contamination from dust, cobwebs or insects. Use a vacuum cleaner around the cover of the alarm to remove contamination.
• Check (at least annually) that the alarm will operate on back-up battery power only by switching off the mains supply and pressing the test button.

27. How long will the battery last?

This will depend on a number of factors that will differ slightly according to the type of alarm in use. The Aico Ei140 series alarms are supplied with an Alkaline battery which, dependent on conditions, can provide up to 4 years standby supply, up to 2 years without mains power. The Aico Ei160 series alarms are fitted with rechargeable Lithium power cells which are continuously charged by the alarm circuitry. They have a life expectancy greater than that of the Smoke Alarm, i.e 10 years or more,which eliminates the need for replacement.

28. How will I know if the battery has failed?

If either, the voltage of the battery falls to a sufficiently low level, or the internal resistance of the battery reaches a predetermined state, the alarm unit will emit a warning beep every 40 seconds. In the case of the Aico Ei140 series alarms, it is probable that the alkaline battery in the unit requires replacement. Access to the battery is gained by removing the alarm from the Easi-fit mounting plate. The power cells on the Aico Ei160 series alarms are not replaceable. If these units emit a low battery warning beep it is probable that the mains supply has failed. The cables, fuses etc should be investigated and the fault rectified. If the beeping continues the alarm may have a fault and it should be returned for inspection.

29. How long do Smoke Alarms last?

Miscellaneous
There is no technical reason why a Smoke or Heat Alarm should not last up to 10 years, but the actual lifespan will depend to a large extent on where and how the alarm has been sited, installed and maintained. The most common cause of alarm failure is due to contamination of the sensor chamber and/or electronics. In certain circumstances, even with regular cleaning, contamination can build up in the smoke sensing chamber causing the alarm to sound. If this happens the alarm must be returned for servicing or repair. All manufacturers of smoke alarms recommend that their products are replaced after 10 years use.

30. How do I stop nuisance alarms?

False alarms are usually a result of incorrect siting of the Smoke Alarm, by contamination as a result of building/redecoration operation, or poor levels of maintenance. For instance, if Ionisation alarms are sited too close to a Kitchen, false alarm will often result due to invisible cooking fumes reaching the alarm. Optical alarms are liable to contamination from dust and fibres, often associated with building work being undertaken without the alarms being properly covered. The Aico Ei140 and Aico Ei160 series smoke alarms are supplied with a ‘hush button’ that can be pressed to desensitise them to allow time for the source of the problem to be investigated. Use of the ‘hush button’ will only silence the alarm for 8 – 10 minutes after which the alarm will automatically reset. If the cause of the false alarm is contamination, the only method of permanently silencing the alarm is to remove the contamination source. This may not be possible without removal and cleaning of the alarm itself. It can be difficult to reach the hush button in some instances, particularly for the elderly and infirm, so the installation of a wall mounted System Remote Control Switch Ei1529RC should be considered to overcome this problem.

31. What is the radiation risk from Ionisation Smoke Alarms?

The National Radiological Protection Board (NRPB), UK have carried out extensive tests on Aico Ei professional Ionisation Smoke Alarms and have concluded that they are radiologically safe. They estimate that we receive 10,000 times as much radiation from our surroundings as we would from an ionisation alarm in normal use.

32. How do I dispose of redundant Aico Ei alarms that contain a NiCad battery?

The early 150 series alarms contained a NiCad battery and some may now be reaching their end of life. The Cadmium contained within the battery is a restricted substance under The Batteries and Accumulators Regulations 1994 and cannot be disposed of in normal waste. Aico / Ei Electronics take their responsibilities to the environment seriously, and will accept redundant Ei product back for recycling/disposal. The Aico Ei140 and Aico Ei160 series do not contain NiCAd batteries, so are not subject to disposal restrictions.

33. Are the Aico Ei alarms with rechargeable Lithium Cells compatible with previous models?

These have been designed to be fully compatible with previous Smoke and Heat Alarm models. Therefore if an old model 150 series mains powered alarm should require replacement, the equivalent model in the new 150 series can be easily and safely installed in it’s place. All Aico Ei140, 150 and 160 series alarms are also fully compatible with each other.

34. Why choose Ei Professional/Aico Ei Smoke Alarms?

To purchase Aico fire alarms, sounders, remote control switches, manual call points, bases, repeaters, CO alarms, remote sounders, relay bases, or covers – visit the Domestic Fire Alarms section under the Fire Alarms, Fire and security. Also, to help you in your choice of the domestic fire alarms, we also recommend the Domestic alarm selector, choosing what alarms to fit and where, based on BS 5839-6:2004.

What does the British Standard BS 5839: Part 6: 2004 recommend?This is the definitive Code Of Practice to which architects, building professionals, enforcing authorities, landlords and installers should refer for recommendations on the design, installation and use of smoke and heat alarms in the majority of domestic dwellings. Landlords in both the public and private sector are considered to have a Duty of Care to fit compliant smoke and heat alarm systems.

System Grades

Six different grades of fire detection systems are defined and – generally speaking – the greater the fire risk the more sophisticated the system should be. Briefly, these grades are as follows:

• Grade A – A full system with control and indicating equipment installed to BS 5839: Part 1
• Grade B – Detectors and sounders using simpler specified equipment
• Grade C – Detectors and sounders or alarms with central control
• Grade D – Mains powered alarms with an integral stand-by power supply
• Grade E – Mains powered alarms with no stand-by power supply
• Grade F – Battery powered alarms

System Categories

Three different categories of life protection systems are defined. Briefly, these categories are (starting at the highest):

• LD1- Alarms in all circulation spaces that form part of escape routes and all areas where a fire might start, but not bathrooms, shower rooms or toilets
• LD2 – Alarms in all circulation spaces that form part of escape routes and rooms or areas that present a high fire risk
• LD3 – Alarms in circulation spaces that form part of escape routes

BS 5839: Part 6: 2004 emphasises that no one type of alarm is most suitable for all applications. Consideration must be given to the most suitable type of detection – optical, ionisation and heat.

New build properties & materially altered dwellings one to three storeys – Grade D, LD2

• Mains alarms with battery back-up
• Optical smoke alarms in circulation spaces – hallways and landings e.g. Ei166RC with or without RadioLINK
• Heat alarm in the kitchen e.g. Ei144 or Ei164RC with or without RadioLINK
• Smoke alarm or heat alarm as best suited for the particular circumstance in the main living room
• All alarms must be interconnected
• The sound pressure level of the alarm signal measured at the doorway of each bedroom with the door open should be at least 85dB(A)

Existing tenanted properties two and three storey – Grade D, LD3

• Mains alarms with battery back-up
• Optical alarms in circulation spaces – hallways and landings e.g.  Ei166RC with or without RadioLINK
• If a fire risk assessment shows the property or occupier to be a high fire risk, increase the number of alarms installed to meet the risk – e.g. follow recommendations for an LD2 installation
• All alarms must be interconnected
• The sound pressure level of the alarm signal measured at the doorway of each bedroom with the door open should be at least 85dB(A)

Existing tenanted properties single storey – Grade F, LD3

• Battery powered with a minimum battery life of 5 years e.g. Ei 10 year alarm
• Optical smoke alarm in circulation spaces – hallway
• If a fire risk assessment identifies a concern that the occupier cannot or may not replace a battery, use mains alarms or mains with battery back-up
• If a fire risk assessment shows the property or occupier to be a high fire risk, increase the number of alarms installed to meet the risk – e.g. follow recommendations for an LD2 installation

What do Building Regulations Demand in New Build & Materially Altered Dwellings?

Architects, builders and installers must comply with Building Regulations and install mains powered alarms in new and materially altered dwellings.

In England & Wales

Building regulations approved document B (Fire Safety) minimum requirements are currently Grade D, LD3, but it also defines that installation should be to BS 5839 Pt. 6 and therefore Grade D, LD2 is recommended.

Grade D, LD3

• Mains alarms with battery back-up with the mains supply taken from a lighting circuit or a dedicated circuit from the distribution board
• Smoke alarms are required in the circulation spaces such as hallways and landings. In general optical alarms are recommended e.g. Ei146, Ei166RC
• Heat alarm to be installed in the kitchen where there is no door separating the kitchen from the circulation space, e.g. Ei144, Ei164RC
• Smoke and heat alarms must be interconnected
• Alarms may be interconnected using radio-links

Northern Ireland

Building Regulations (Northern Ireland) Technical Booklet E (Fire Safety) requirements were amended in June 2005 to:

Grade D, LD2

• Mains alarms with a battery back-up
• Smoke alarms are required in the circulation spaces, hallways and landings
• A smoke alarm is required in the ‘principal habitable room’ e.g. living room
• A heat alarm is required in every kitchen
• Loft conversions require all the above to be installed
• Smoke and heat alarms must be interconnected
• Alarms may be interconnected using radio-links

Scotland

Building Standards Technical Handbook No 2 (Fire) requirements are currently:

Grade D, LD3

• Mains smoke alarms with battery back-up
• Smoke alarms are required in the circulation spaces, hallways and landings
• Smoke alarms must be interconnected
• Alarms may be interconnected using radio-links
