Two-Wire Sounders & VADs

Two-wire fire alarm sounders and visual devices are alarm and indication devices designed to operate with specifically compatible two-wire fire alarm panels and fire detectors. They provide the primary source of alarm and indication on these systems. The two-wire design allows for the sounders and visual devices to be installed on the same pair of cables as the fire detectors and manual call points, providing cost savings on installation.

Compatibility is restricted to the specific brand/range being used on the rest of the system.
