Recommended Testing
7
To ensure ongoing functionality of AC42, it is recommended to check the following
interfaces every 6 months:
● Short each input to its adjacent GND port and verify that LED illuminates.
● Use multimeter to confirm expected impedance across relay outputs.
○ Closed across NC and COM
○ Open across NO and COM
● Use multimeter to verify correct voltage is supplied at 12V AUX output, Relay Contact
outputs, and reader power outputs.
● Check the shielding cables of the readers and other AUX wiring, if any, for proper
connection to the grounding screw/s on the chassis.
● If a back-up battery is in use, follow installation, maintenance, and other safety
guidelines and recommendations from the battery manufacturer
