I think we are wandering away from the main issue here. Most school maintanance contracts that I have come across are priced for "normal working hours" but when you arrive on site nobody wants to hear sounders, so you are left with the option of abandoning the maintenance or disabling sounders during the test. Given the size and poor escape route planning in most schools that I have maintained, (not to mention the fact that fire escape passageways are commonly used for storage) I would not want my child in a building where some fire alarm engineer is wandering around in the building, a real evacuation is required, sounders are disabled and the only person who can re-enable them has to be located and returned to the panel in order for this to happen. Meanwhile fire/smoke is spreading etc...
A large University that we maintain has a fire warden system (hand held air horns & a warden/marshall on every floor) that can be put into action during any disablement. (Probably required to compensate for lower intelligence levels of students when compared to primary school kids!) so if a university has seen the need for this, presumably after risk assesment, then why do schools not do something along the same lines?
To respond to Mike Buckley, I have not come across any school that had an alternative system in palce for evacution in the event on alarm failure. What is even more worrying from a parents point of view ( I know this has been raised elsewhere in this forum) is that one local authority on our client base has about 40% of its schools on "mains only" systems, so some alternative evacuation plan should be in place anyway!
Back to my origial point, is there any legislation covering this issue?
If fire panel manufacturers have seen the need to design a "walk test by zone" feature into their systems, are the anticipating future legislation or does it already exist?
I am not personally prepared to put lives at risk so that maintenance quotas can be met.
