Each Hush Button can be looked upon as a miniature fully monitored, self-powered single zone fire alarm panel that sits and is addressed on an analogue loop with the ability to communicate its status back to the host fire panel.

Typically one double gang Hush Button is fitted in each HMO dwelling complete with conventional detectors and sounders to provide occupants with a simple, cost-effective means of invoking two types of 'hushed' period, as specified in clause 12.2 of BS 5839 part 6.

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.

Moreover, the fact each Hush Button and its local cabling is monitored means any open circuit, short circuit or tampering fault is relayed to building management via the analogue loop and host fire panel for appropriate remedial action - a feature that is simply not available on existing Mains/battery type alarm systems.

General operation

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 there is no one in the apartment to intervene during a local alarm condition (i.e. if the 'Hush' button is NOT pressed): The local alarm sounders will sound for a period of two minutes. If the local alarm clears within these two minutes, the Hush Button will return to its normal state. If the local alarm is still present after two minutes, the alarm will be signalled to the host analogue fire panel and a general alarm condition will be annunciated around the building as programmed.

If the 'Hush' button is pressed DURING a local alarm condition: A hushed period of two minutes will commence starting from when the Hush button is pressed. If the local alarm is cleared within these two minutes, the Hush Button will return to its normal state. If the alarm doesn't clear, 15 seconds before the hushed period is about to expire, a beeper will sound to inform the occupant that the alarm is about to be signalled to the host fire panel. If the 'Hush' button is pressed again during this 15 second period, another two minute hushed period will commence.

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.

Manual call points

If a manual call point is connected to the Hush Button's detector circuit, provided its resistance when operated is less than 400 ohms, its operation will immediately trigger the Hush Button's sounder circuit and signal a general alarm condition to the host firepanel.

General fire conditions

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.
