The Aiphone LEM-1DLS single-door Access Sentry System starter kit includes one door intercom, one master intercom, and an AC transformer 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. The master intercom emits an audible signal to indicate an incoming call from the door. 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. The chime and audio volume is adjustable on the master intercom. The housing is black plastic for the door intercom and white plastic for the master intercom. The master mounts to a desktop or wall using the included mounting hardware. Additional LEM-1DL master intercoms (sold separately) can be connected to the system using an Aiphone DAK-2S adapter (sold separately) to extend coverage into other rooms; each additional master requires its own AC transformer or DC power supply (sold separately).
