6. Battery
The door contact comes with the battery already installed.
Low battery detection
 The door contact has a low battery detection system.
 The supervision function on the CTC1000 control panel checks the
battery status every 30 to 50 minutes.
 The control panel must detect the low battery signal for at least
10 times with a time interval of 10 minutes.
 If battery is low, the control panel will display an error message.
Replacing the battery
1. Put the control panel in configuration mode to avoid triggering
the tamper alarm (tamper alarm is not active in this mode).
2. Remove the screws and the cover.
3. Remove the old batteries.
After removing the old batteries, press the tamper switch twice
to fully discharge before inserting new batteries.
4. Insert new batteries (always use the correct battery type: see
Technical specifications below). Make sure the polarity is correct.
5. Put back the cover and fasten the screws.
Note
Low battery detection operates where the door contact has enough
reserve power to typically operate for 1 month before complete
exhaustion. When the door contact has a low battery, its LED will
flash.
WARNING
 Do not puncture or throw batteries in fire as they might
explode.
 Keep batteries away from children.
