installation process of the easichange replacement kits, described below, negates the need for an electrician, though you must ensure that mains power to all interlinked alarms is cut before beginning work. The interlink wire can carry a live electric current between alarms if they are powered from different circuits.
Installation Steps
1.Turn off the power at your fuse box or consumer unit.Take care to turn off all circuits powering any of your alarms, as the interlink wire can carry a live electric current.
2.Remove your old BRK smoke or heat alarm from its baseplate by twisting and the unplugging the connector.
3.Insert the supplied 9V battery into your easichange replacement alarm and close the unit securely.
4. Install the alarm on your old BRK baseplate: Connect the plug so that the wires of the connector line up with the pins on the alarm then twist the alarm fully onto the baseplate.
5. Repeat steps 2 to 4 for all of your old BRK alarms. We recommend replacing all alarms in the system together to maintain optimum system operation; failing to do so may compromise interlink performance.
6. Turn the power back on at the fuse box.
7. Test each of your smoke alarms separately to ensure the whole system is functioning correctly. When you test one alarm, they should all sound, however it is important to press the test button on each alarm too.
