The BPT SI/200 two entrance switching relay for system 200 audio systems.
This usit is designed for us in two entrance systems. When a visitor makes a call from the first entrance, the switch relay transfers the call from that panel to the audio handset of the flat being called. Similarly when a visitor calls from the second panel, all the call and speak and release functions are transfered to suit.
- Allows the residence to communicate and control the opening of multiple entrances
- Can be used in an audio entry installation with a maximum of two entrances
- An additional unit will be required for every other entrance
