BPT XA/301LR | Power Supply And Control Unit

BPT XA/301LR | Power Supply And Control Unit

Power supply and control unit, with ECHELON bus, which makes it possible to create System 300 systems, either standard or residential type. It allows conversation between entry panel, internal extension and porter switchboard. It manages service controls (self-connection/selection of entry panels, door lock release, stair light, auxiliary control/porter call) and busy status. For data lines to main and/or block entry panels, the unit communicates using LON TALK protocol, while to internal extensions it uses BPT X2-X1 TECHNOLOGY protocol.

The connection bus to entry panels is composed of 3 twisted pairs plus power supply if it is video, while if it is audio connection is made by two twisted pairs plus power supply. The connection bus to internal extensions is composed of only one twisted pair (System X1) or by a twisted pair plus power supply (System X2).The unit is equipped with a CNV connector for connection to the XAV/300 video modulator and a CNS connector for connection to the ICB/300 selector.

Compatibility with XA/300LR

Problems of incompatibility (such as use of VSE/300 or use of EXEDRA type internal extensions) can be resolved by changing the output voltage of Bus B from 20 V DC to 18 V DC with potentiometer P2.
