Aiphone LEM-1DL — Single-Call Master Station with Door Release for Chicago

Aiphone LEM-1DL — 1-Call Master Station with Door Release

The Aiphone LEM-1DL is the simplest LEM Series master station — push-to-talk (simplex) open-voice communication, voice-volume control, and N/O dry-contact door release. Supports up to 1 door / sub station (without DAK-2S). 12–16 V AC or 12–24 V DC powered, 200 mA max at 24 V DC. For a storefront back door it’s hard to beat — buzzer at the door, master by the register, press to talk, hit the release.

When LEM-1DL Fits — Simple Single-Door

Pick the LEM-1DL when the project is the simplest possible audio intercom: one master indoors, one door / sub-station outdoors, with door-release functionality. For 2–3 doors with selective door release, step up to the LEF-3L. For 4–5 stations, see the LEF-5. For up to 10 stations, see the LEF-10S. Pair with the LE-DA door station.
