g. 1
2. Remove the top case ( g.2).
3. Pull the plastic tab o to activate the sensor ( g. 3). The door
sensor will start to scan for the network and ash LED 3 times.
Pair & Register
1. Follow the instructions on your Touchstone Hub or Touchscreen,
to add new Door Sensor (CHS-888).
2. During the pairing mode, the status LED will ash until the sensor
is connected. ( g. 4)
Notes: A scan is performed every 5 seconds.
The LED ashes 3 times when each scan is initiated.
The sensor sleeps between scans to conserve battery.
If after 20 scans a network is not found, the sensor enters into sleep
mode.
The sensor resumes scanning the next time a zone status change
occurs (e.g. fault, restore, tamper, tamper restore, test button
pressed, etc.) This allows user interaction to cause the sensor to
resume scanning.
If you still have problems to pair the sensor, you may follow the
factory reset procedure to reset to factory defaults.
