Installing Smoke Alarm/Detectors
What Is a Hardwired Smoke Detector?
How to Wire Smoke Detectors in a Hardwired System
If more than one smoke alarm is to be installed, they should be interconnected. Using the three-wire cable, the cable should be run from the first alarm to the next one. This is to allow each alarm to communicate with the other detector once smoke is in the air. Before installing each box into the ceiling or drywall, all the cables should be first secured. A mounting plate can also be installed for better security. The smoke alarm/detectors can now be connected, but the method will depend on the type of model you are using. The backup battery of the alarm must also be inserted. To test if the installed smoke detector is working, push the test button. A functioning detector will sound the alarm.
Alternatively, we can install interconnected smoke alarms which utilise Bluetooth connectivity.
