The whole system is geared towards reducing unwanted alarms by putting HMO occupants firmly in control of their own fire detection systems without losing sight of the fact its primary purpose is to protect life and property.
When the fire alarm system is in its normal state (with no alarm conditions anywhere in the building), power is applied to the Hush Button's detector circuit, its detector and sounder circuits are continually monitored for faults, and its power LED is lit. In the event of a local alarm condition (when a fire detector within the flat or apartment has triggered), the Hush Button's local sounder circuit will activate and any output devices connected to it will sound.
If the 'Hush' button is pressed when there are no alarms present: A hushed period of fifteen minutes will commence. During this period, power is cut to the local zone so no alarm signals from detectors will be detected (however a manual call point with a suitable resistor, less than 400 ohms, will trigger a full alarm if activated). If the 'Hush' button is pressed again during this 15 minute period, power is re-applied to the local zone allowing normal signal processing to resume. 15 seconds before the 15 minute hushed period is about to expire, a beeper will sound to inform the occupant that the local zone is about to be re-powered. If the 'Hush' button is pressed again during this 15 second period, another 15 minute hushed period will commence.
If, at any time, the host analogue panel enters a general fire condition, it overrides any hushed state at the Hush Button and turns on its local sounders. Pressing the 'Hush' button in a general fire alarm condition WILL NOT silence the local alarm sounders and the dwelling should be evacuated as per the designated fire management plan.
