The ZP755W-2R is an addressable, weatherproof sounder designed for use on ZP7 compatible addressable fire detection and alarm systems. The sounder is developed for outdoor applications or for use in areas where the ingress of water can be expected e.g. where hygiene requirements demand regular washing of the protected area.

Installed onto and powered by the detection loop, the ZP755 series gives the system designer the flexibility to offer a complete addressable system on 2 wires. Installation costs are thereby greatly reduced whilst system integrity, sounder options and programmed alarm organisation are maintained.
