Check the listing for details. Single Door Access Module ELK-M1KAM. Condition: New. Listed at 139.00 USD. ELK-M1KAM A single door access interface module for use on the M1 and M1EZ8 Control Panels. The M1KAM connects to the 4 wire keypad data bus in place of a traditional M1 Keypad. Since the maximum number of keypads on an M1 or M1EZ8 is 16, the maximum number of M1KAM modules (and controlled doors) is 16, minus any installed keypads. Even though an M1 Keypad can accept a 26 bit access reader, the M1KAM is a more powerful and less expensive access solution. For example; the M1KAM includes a relay (door unlock) output with form “C” dry contacts, making it compatible with most door lock devices regardless of the voltage rating and style (AC or DC).
