Fire alarm manual call points need to be prominently sited, readily distinguishable from non-fire alarm call points and need to be distributed such that, from any point in the building, it is impossible to leave the
storey or the building without passing a fire alarm manual call point.
When
designing a fire alarm system, sufficient call points need to be provided to minimize, to a reasonable extent, the delay between discovery of a fire and the sounding of the fire alarm system. Where the fire hazard level is high and rapid fire development is
anticipated, this delay needs to be commensurately shorter.
Manual call points can, if present in unsupervised areas, be subject to malicious operation. For this reason
,they are not normally provided in, for example, public common areas of shopping complexes and certain
public houses. In public car parks within a building, use of an emergency voice communication system could be considered instead of manual call points.
