What should I do if the associated LED on the 4XZM does not activate for alarm, trouble, or supervisory conditions on System Sensor PDRP-1001 Control Panel?

If the associated LED on the 4XZM does not activate for alarm, trouble, or supervisory conditions, it could be due to an optional module trouble: 1. Make sure the module is properly installed. 2. Move the disable switch SW1 on the 4XZM to the left.
