The Aiphone LEM-1DLC single-door Access Sentry System master intercom works with any Aiphone LE or LS Series door intercom (sold separately) to enable audio communication with visitors at a door prior to granting access using the door-release button. The door-release button works with an electric strike (sold separately) to remotely unlock the entrance for the visitor. Up to three additional Aiphone LEM-1DLC master intercoms can be connected to extend door monitoring capability to other rooms within the building or into large areas. The master intercom emits an audible signal to indicate an incoming call from the door intercom. Pressing the push-to-talk button allows the master intercom operator to talk to the visitor, and releasing the button automatically transmits sound from the door intercom. An LED light indicates when another master is in use in the system. The chime and audio volume is adjustable. The housing is white plastic and mounts to a desktop or wall using the included mounting hardware. The system requires an AC transformer or DC power supply (sold separately).
