Aiphone LEM-1 – Frequently Asked Questions

1) What is the difference between the Aiphone LEM-1 and LEM-3 master station?
Station count. The LEM-1 handles a single sub or door station; the LEM-3 handles 2 or 3 remote sub or door stations. Both are audio-only push-to-talk masters from the same LEM Series, so pick by how many entries or rooms you need to answer from one desk. If you have one back door today but plan to add a second entry later, order the 3-call now rather than replacing the master.
2) How far can I run the wire from an Aiphone LEM master station to the door station?
650 feet using Aiphone #822202 22 AWG, or 1,600 feet using #821802 18 AWG. Both are 2-conductor with an overall shield. For a small office or a monitoring room in the same building, 22 AWG covers it. For a run out to a warehouse gate or across a campus building, spec the 18 AWG. Wire is a separate order line, not included with the master.
3) Which door stations work with the Aiphone LEM master station?
LE Series door stations. The LEM masters are built to pair with LE Series entry units, and that is the compatibility the product data states. Mixing in a door station from another Aiphone family or another brand is not covered here, so build the system as LEM master plus LE door stations.
4) Is the Aiphone LEM intercom hands-free or do you have to hold a button to talk?
You hold a button. The LEM Series is push-to-talk, simplex audio, meaning one party talks at a time and the master operator presses to speak and releases to listen. It is not a full-duplex, open-conversation intercom. If your staff need to talk and listen at once, or need to see the visitor, a simplex audio-only master is the wrong choice.
5) Does the Aiphone LEM master station have video, or is it audio only?
Audio only. The LEM Series masters carry voice between the master and the sub or door stations with no camera or screen anywhere in the system. For a receptionist who needs to identify a visitor before releasing a door, this is not the unit; specify a video entry system instead. Where the operator only needs to hear and answer, the audio-only master keeps the wiring to a shielded 2-conductor pair.
6) Can an Aiphone LEM master station sit on a desk, or does it have to be wall mounted?
Either. The LEM masters mount on the wall or sit on a desktop, so a guard station, reception counter, or nurse desk can take the unit without cutting into finished wall. That flexibility is why these turn up in monitoring rooms and small retail back offices where there is no dedicated mounting wall.
7) What power draw should I plan for on an Aiphone LEM intercom?
200 mA current draw, with 350 mW of audio output at the speaker. That is a small load, so sizing the supply for a single LEM master and its stations is straightforward on a typical low-voltage panel. Worth handing to the electrician along with the wire spec so the circuit and the cable get pulled together on the same trip.
8) Is the Aiphone LEM Series suitable for a commercial building or is it a residential intercom?
Commercial. Aiphone classes the LEM Series as commercial product, and the typical installs are office buildings, small retail, monitoring and security rooms, multi-tenant residential properties, schools, healthcare, and industrial or warehouse space. It is a simple point-to-point audio system rather than a building-wide directory intercom, so it fits a handful of openings, not a 40-unit tenant entry.
9) Can you turn down the volume on an Aiphone LEM master station?
The LEM masters have adjustable voice volume control on the unit, so the audio can be set for the room it lands in. That matters in a quiet reception area where a full-volume announcement carries into the lobby, and just as much in a noisy shop where the default is too quiet to hear over equipment.
