Alpha Communications® Home and Office Intercoms

Home and Office Intercoms

Indoor Remote without Door Release Button. Used on Tek-Com Intercom and Tek-Sound Music-Intercom systems. Has built-in slide type volume control switch.

The Alpha Communications®/Tektone IR704B indoor remotes are designed to work with the PK724 (Tek-Com) system amplifier or the 'EK' series music-intercom masters. They can be flush, surface or desk mounted, with the appropriate back box/housing.

The IR704B indoor remotes have three (3) buttons for Indoor Call, Monitoring, and Door Answering from any IR704B station. A high/low/off 3-position volume slide switch is standard. No other IR704B station can eavesdrop on another IR704B station, unless the Inside Speaker or Monitor button is depressed. Any IR704B can call all of the other IR704B's. Any IR704B (in monitor position) can be monitored by all of the other IR704B's, and any IR704B can answer a voice call from a door remote station.

The IR704B remotes are 4-wire type and must be used with a good quality 2-twisted pair type cable (with at least 10-12 twists per foot). The wire may be solid or stranded type. A maximum of 18 IR704B stations can be connected to a single PK724 amplifier.
