BPT VSE/301 intercom selector

BPT VSE/301 intercom selector

Using the selector, different groups of intercom receivers can be connected with the main line of an X1, X2 systems or system 300 installation. The selector is capable of supplying power to intercom receivers directly from the X1 bus with a single twisted pair.

The intercom system can also work independently without connection to an audio or video entry control system. A total of ten receivers can be activated by the same call, if using a monitor this decreases to nine.
