In the series of Fire safety design, below there are the last 3 stages: Choice and siting of alarm devices, The zoning of the building, and selection of control & indication equipment. The previous stages were: Initial design considerations(stage 1), Siting of manual call points(stage 2), Select automatic detectors(stage 3), Siting automatic detectors(stage 4), and [...]

This article is a continuation of the Fire Safety Design stage 1, and continues with Fire Design stage 4. Read more about the second stage(siting of manual call points) and the third stage(select automatic detectors) in Fire Safety Design.
Fire Safety Design stage 2 – Siting of Manual Call Points
All manual call points, whatever the system, [...]

In this article, which is a continuation of the Fire Safety Design stages 1, 2, and 3, you can read about: the spacing of detectors in normal applications: for pitched roof, near obstructions or unusual ceilings; siting optical beam detectors, and other considerations.
Spacing of detectors in normal applications
Under flat horizontal ceilings – smoke and heat [...]

Comparison between conventional and analogue addressable systems
The conventional system
A conventional system incorporates detectors which are in one of two states: either on or off. The detectors incorporate the criteria for measuring levels of fire phenomenon and, after reaching the levels defined within the standards, will switch from an Off state to an On state. Once [...]
