Multipurpose Intercom Unit – BC735 -Description

The Multipurpose Intercom Unit – BC735 is a dust and splash proof substation without keyboard, loudspeaker and microphone. The station requires an external loudspeaker, which can also be operated as microphone (Talk-back function). An external microphone or handset can also be installed. The station also includes an internal relay for control of door lock, camera, extra call warning device, etc. The station can receive call from all other stations in the system. Direct one key dialling can be operated by installing one external push button.

BC735 include its own processor and software, and shall therefore not be connected to a central exchange. All programming is carried out via switches inside the station.

A 10 W amplifier, FC740, can be installed inside the station cabinet. The amplifier offers a “Talk-back” function. The external loudspeaker can then be used as a combined loudspeaker and microphone. And additional 24 VDC or 24 VAC power supply is then necessary. An external handset module can also be connected to BC735.

All stations are connected in parallel. The cable system is therefore very flexible. It can be star or bus structure. You need one pair for audio and signalling, one pair for power and one pair for program distribution. This is a total of 3 pair twisted cable. A 2 pair twisted pairs cable is sufficient if program distribution is not required.
