.....Wiz, sticking with my HMo for a moment. AFD in each bedsit is critical, because if a detector isn't working in a bedsit and a fire occurs and spreads, the first we would know about it is when smoke hits a detector in the communal areas. By that time the MOE is compromised. How do we check those detectors if the tenants are out and landlord or keyholder isn't available? Do we just assume the system may be ok if say the communal detectors are tested it will probably be ok? And furthermore who's job is to go round testing anyway? Is it an enforcing officer, a fire consultant? or fire alarm engineer? If so I'll need to be carrying ladders and test equipment in my car from now on! (sorry I don't wish to be confrontational)......
M.M., obviously you are concerned by this problem. I believe the level of concern could be modified by the results of some simple testing of the system.
It is the case that many panels, especially non-addressable, indicate only general purpose fault warnings and don't give enough information about the type and extent of the problems caused by the fault. Carrying out simple basic testing of what the fire alarm system is supposed to do will allow us to assess if the problem is extremely serious (nothing works!) or probably far less serious (the fault does not appear to have any current affect on the workings of the system!).
From the results of the test we can probably also work out if the extent of the fault is limited to specific areas etc. Obviously the more we test, if access etc. is available, the better our assessment of the seriousness of the problem can be, and also what steps the responsible person probably has to take to ensure the continued saftey of the occupants of the building.
Simple testing probably only requires a can of test smoke, a mcp test key and working eyes and ears, to be carried out effectively. We all know what a fire alarm system should be capable of doing, so it isn't that difficult to carry out basic tests of its most important functions.
Obviously the fault still needs investigating and rectifying asap. I wouldn't be happy with people sleeping in a building with a fire alarm system with a 'fault' on it without suitable fire detection patrols AND a fully working fire alarm warning sounder system.
