ELK - M1KAM - Single Door Access Module

Product Overview

The ELK-M1KAM is a streamlined single-door access interface for M1 and M1EZ8 control panels that connects directly to the 4-wire keypad data bus. Designed as a cost-effective alternative to traditional keypad-and-reader setups, it features a built-in Form C relay for door strike management. The module includes supervised inputs for monitoring door status and Request to Exit (RTE) buttons, alongside three specialized outputs for signaling armed status, system readiness, and "door held open" alerts.

Key Configuration

• • Input: 26-bit Wiegand reader compatible (e.g., ELK-106055)
• • Relay output: Form C dry contacts for door strike power (compatible with AC or DC lock devices)
• • Operating voltage: 13.8 VDC; current draw: less than 30 mA idle, 44 mA fully active
• • Supervised inputs: RTE (Request to Exit) button/device, door status sensor
• • Housing dimensions: 4.25" × 6.375" × 2.125"; circuit board: 3.95" × 2.875" × 0.95"

Key Features

Replacing a standard keypad on the RS-485 bus, this module uses heavy-duty Form C relays to manage door strikes and low-current outputs for status and alarm signaling. It features four adjustable timers for exit and "door held open" functions, supported by an integrated hardware watchdog for maximum reliability.

Technical Context

Maximum number of access modules and keypads per system: 16. Connections via unpluggable screw terminals (16 position). Includes hardware pack with 4 screws, 2 resistors, a diode, plastic housing, and instructions.

Installation Notes

Mounts in place of an M1 keypad on the RS-485 4-wire keypad data bus. Each M1KAM counts toward the maximum of 16 keypads/modules per system. Form C relay contacts compatible with most door lock devices regardless of voltage rating or style (AC or DC).
