4. Press down on the battery until it fits into place.
5. Close the device cover and fasten the cover screw. See Figure 9.
Note:
After restoring a low battery, the system may take up to 5 minutes to clear the
trouble.
Wiring the auxiliary input
About this task:
The auxiliary input is programmable as either Normally Open (NO), Normally Closed (NC), End Of
Line (EOL), Double End of Line (DEOL), and Triple End of Line (TEOL).
1. Remove the device cover. See Figure 5.
2. Use a long nose pliers to remove the wiring inlet.

3. Connect the auxiliary sensor contacts across the auxiliary input terminals.
4. If the auxiliary input is defined as NC, series connected NC sensor contacts must be used
exclusively. An EOL resistor is not required.
5. If the auxiliary input is defined as NO, parallel connected NO sensor contacts must be used
exclusively. An EOL resistor is not required.
6. For EOL supervision, NC sensor contacts can be used. A 5.6 kΩ EOL resistor must be wired at
the far end of the zone loop.
