- COM: Communication Port or Ground N.C: Normally Closed - A Trigger that initiates when an object disrupts the communication line of 2 sensors
- N.C: Normally Closed - A Trigger that initiates when an object disrupts the communication line of 2 sensors
- N.O: Normally Open - A Trigger that initiates when an object completes the communication line of 2 sensors.
STEP 2. Connect the N.C. (Normally Closed) wire to one of the numbered ports. Connect the COM wire to the COM / Ground Port.
Ala r m Inputs are grouped in fours.
