NESS M1 KAM Single Door Access Module

This access control module is designed for use with a Ness ASK EM Marrin Format Reader and installs in place of a NESS M1 keypad, operating via the RS-485 4-wire keypad data bus.

It features heavy-duty Form “C” relay contacts for switching door strike power, and includes low-current 12VDC outputs (50mA) for DOTL alarm, System Ready to Arm, and System Armed indications.

The module also provides supervised inputs for a Request to Exit (REX) button or device and a door status sensor. Additional features include four selectable timing settings for REX and DOTL functions and a built-in hardware watchdog circuit for enhanced reliability.
