sorry gents,
this is a question for the FPA eurpoean diploma and it states"
Explain the circumstances in which a staff alarm might be considered and the arrangements that you would incorporate within a staff alarm facility to ensure an adequate degree of safety for occupants of a multi-storey office building"
I've wrote about DDA for deaf people, and maybe for key staff such as fire wardens so they can possible investigate while in pre alarm, but can't find any more information.
thanks for the help guys
You are I think, at the junction between; panic alarm, nurse alarm, fire alarm, burglar alarm, …what ever alarm…etc, but sorry this seems to be 4th dimension dilemma it needs a differential equation to guess certain solutions with less certainty… etc
Tonyfog, then it is a staff alarm facilty you are talking about i.e. something that warns the staff of a fire condition before a general evacuation signal. In a building where everyone knows the different signals, the staff alarm might be a different alarm sound. In other circumstances it might be just a visual signal. Wireless signals may also/or instead be used to contact staff directly by radio/pager.
I don't know much else about staff alarms although my experience is that many fire officers are wary of the delay they add to the evacuation process and don't recommend them except in buildings with large numbers of the general public, where mass evacuation can be disrupting or needs to be carefully controlled.
p.s. pre-alarm is normally a function of analogue addressable systems only, where a signal is generated at a detection level just slightly lower than the detection level of a full fire condition. This pre-alarm may or may not be an indication of an impending full fire condition, but where it is, it normally follows just seconds after the pre-alarm.
