IR704B / IR704BD / IR804A Indoor Remote Stations
The IR704B, IR704BD and IR804A Indoor Remote Stations combine modern styling with ease of operation to provide natural, clear voice communication. The stations are designed for use in home and office, and similar applications, are used with the PK724 amplifier and EK714W AM/FM Master Stations. The operation of the stations is simple and efficient. The caller, by pressing the 'Inside' button can send a voice message to all other inside receiving stations at once. To answer, the 'Inside' button must be depressed at the receiving station, to reply. 

Pressing the 'Monitor' button acts the same as the 'Inside' button, except it locks down, allowing all of the inside receiving stations to 'monitor' the station with the monitor button depressed. Depressing the 'Outside' button allows communication to the outdoor remote station(s), and hands-free reply, until it automatically turns off after approx. 30 seconds. The IR704BD also has a 4th button which is a momentary electric door release button.

The IR704B and IR704BD stations are the lowest cost models available and have a 3.50" (89mm) speaker, and are fine most system applications. For better music fidelity, or to cover a larger existing wall opening, the IR804A may be used. The IR804A is functionally the same as the IR704B, but with a larger, 4.0" (102mm) x 6.0" (152mm) speaker, and larger faceplate.
