How it works
At the planning stage, fire zones are designated as either "Dwelling" or "Communal". Detectors in the dwelling zones have the facility to use "checkpoint" technology. "Checkpoint" technology is the ability to select a checking period for individual detectors to confirm the smoke/heat detected as a genuine fire not an unwanted alarm. This checking period can be selected between 1 - 8 minutes at commissioning stage after consultation with fire officers or other authorised bodies.
Dwelling Zones (e.g. apartments, hotel rooms etc)
Upon detection of smoke/heat in the dwelling zone, only the local (room) sounder will sound. The detector is then automatically checked by the control panel for continued presence of smoke/heat during this checking period (e.g. 3 minutes). If during this time the detector ceases to sense smoke/heat, the control panel will reset the sounder automatically and the system will revert to its normal state. If, however, at the end of the period the detector is still sensing smoke, the control panel will automatically sound all alarms in the building for full evacuation.
Communal Zones (e.g. corridors, hallways)
In the event of a detector alarm or callpoint activation in the communal zone, all the alarms in the building, including dwelling zones, will immediately be operated.
