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 rotary type volume control switch.

The Alpha Communications®/Tektone IR804B indoor remotes are designed to work with the PK724 (Tek-Com) system amplifier or the 'EK' series music-intercom masters. They can be flush or desk mounted, with the appropriate back box/housing. They basically work the same as the IR704B type stations, except they have a larger speaker for improved voice and music fidelity.

The IR804B indoor remotes have three (3) buttons for Indoor Call, Monitoring, and Door Answering from any IR804B station. A multi-level rotary volume slide switch is standard. No other IR804B station can eavesdrop on another IR804B station, unless the Inside Speaker or Monitor button is depressed. Any IR804B can call all of the other IR804B's. Any IR804B (in monitor position) can be monitored by all of the other IR804B's, and any IR804B can answer a voice call from a door remote station.

The IR804B 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 eight (8) IR804B stations can be connected to a single PK724 amplifier.
