Description
The Apartment Module (AM) is a loop powered addressable device that helps reduce the costly
consequences of an unwanted alarm
An occupant is able to silence a local audible warning, activated by a local smoke detector, and allowing a
preset time to investigate the cause of the alarm. Local smoke detectors can be connected directly to the AM
(conventional) or connected to the addressable loop (addressable) and assigned to the AM.
The local smoke detector is self resetting and if the smoke clears, then the system will return to normal. If
the smoke remains, then the local audible warning will resound at the expiry of the preset timeout. A local
smoke detector will NOT cause a general fire alarm.
The fire system will go into general fire alarm (thus calling the brigade) if:
➢
Any thermal detector has gone into alarm (conventional connected to the AM or addressable
connected to the addressable loop)
➢
Any smoke detector in common areas has gone into alarm
➢
Any call point activated
ConfigManager
is programmed to identify the associations of AM’s with the local smoke detectors
(conventional and addressable) and adjustment of the “Investigation” period.
