VH30-2D B&W ReliaBUS™ Video-Intercom Monitors

The Alpha Communications® / S.T.R.™ VH30-2D (apartment house) series ReliaBUS™ monitors are designed to meet virtually any requirement for video-intercom security where it is impractical or too costly to run Coaxial and/or selective 'ring' (point) wires. The VH30-2D is normally used in larger multi-unit buildings, but can be used in smaller buildings as well.

These attractive monitors are conveniently surface mounted right on the wall. Monitors can be changed to desk mount with the addition of a model TZ30 series desk adapter

All VH30-2D series ReliaBUS™ monitors feature a crystal clear 4.0" black and white flat screen monitor (measured diagonally), textured finish handset (to minimize scratches and fingerprints), electronic tone signalling, flexible coiled cord and momentary door release (key symbol) push button switch. 

All VH30-2D series ReliaBUS™ monitors use simple 6- conductor parallel (loop) wiring for all risers, without any riser coaxial cable. No Selective 'ring' (point) wires are needed.
