Which System? - Bi-Wire

Bi-Wire - System Architecture

The JSB Bi-Wire systems is based on standard conventional system technology, but it also incorporates additional functionality to enable the callpoints, detectors and sounders for each separate zone to be wired on a single common circuit.

This enables the control panel to use a single circuit per zone for connection of detectors, sounders, LED beacons and relays.

Even though the panel continually powers the sounders, control functionality incorporated within the sounders enables them to only be activated in the event of a fire alarm condition.

By combining both the detection and the alarm annunciation wiring into a single circuit, considerable savings in installation time and cabling can be achieved.

Although adding Bi-Wire technology to the detectors and the sounders does slightly increase the equipment costs this is more than offset by the substantial savings in installation and cabling cost.
