Product Description

The Aiphone LEM-1 Open Voice master intercom works with one Aiphone LE series door or sub-master intercom (sold separately) to enable audio communication with visitors at a door and with other rooms within the building. The master intercom can initiate communication with and receive calls from a door or sub-master intercom. Depressing the push-to-talk button on the master allows the user to talk to the door or sub-master intercom user, and releasing the button immediately transmits sound from the door or sub-master intercom to the master for 20 seconds.

At any time, the master user can listen to audio transmissions from the door or sub-master intercom. The audio volume is adjustable, and switching the power button to off silences the master intercom's chime alerts. The housing is white plastic and mounts to a wall using the included bracket. The system is hardwired to be powered by a 6V power supply (sold separately).

We used this as a replacement for our 20+ year old ski-racing intercom. We were pleasantly surprised to find it is exactly like the one we replaced. At first I couldn't figure out why they would still make these, with all of the more modern options out there. Then I pulled out my credit card and ordered it so we could get our old simple system back up and running.

I suppose that answered my question. Thank you AiPhone.

If this one lasts even half as long as our old one did, we'll still be very happy.

It works. If you need one, get one.
