The wireless technology that goes into our range of smoke alarms enables up to 12 units to be fitted within a building typically up to 30 metres apart (depending on the structure). Radio signals are used to interconnect alarms without the need for wiring, so when one unit detects smoke / heat it will alarm and send out a radio frequency alert to all other units that are interconnected, triggering them to alarm as well.
The diagram below demonstrates how wireless smoke alarms set off the other smoke alarms when they are triggered by a fire. The animation has been slowed down to explain the process; in reality this takes only milliseconds.
Upon detecting a fire, a detector unit will alarm with an 85dB sounder alerting anyone in the immediate vicinity that a hazard has been identified.
The alarm unit that has detected the fire sends out a coded radio signal to all other smoke and heat alarm units within the same setup (house coding), alerting them to the danger. The house-coding ensures that only smoke alarms within the same property are going off and not in neighbouring properties.
When the radio signal is received by the other house-coded units, they too will alarm, alerting anybody in the premises that a danger has been identified.
