Replacing the ITS Battery

Step 1:

Remove the ITS cover from the wall.

Step 2:

Remove the retaining screw holding the battery cover in place then remove the flat battery.

When replacing the battery, press and hold the Zone Button after removing the dead battery for 5 seconds to remove any residual charge from the circuit.

Step 3:

Replace the battery with a fresh 3V CR2450.

When the battery is low, a Low Battery icon will appear near the zone name of the sensor. A good battery will last for around 1 ½ to 2 years. When the battery is flat, the zone will change to % control if there are no other sensors in it.
