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.
Self Test
The high efficiency acoustic design together with a low energy 'sound gun' transducer provides a forward sound dispersion with an output of up to 95 dB(A). A volume control is included for areas where a reduced sound output is required. The volume control can limit the sound output by up to 75% of the full output volume.
The ZP755 series features a unique self test facility which is automatically activated during sounder testing. A built in microphone measures the SPL and automatically flags the sounder address and location to the control panel should volume fall below the expected test level.
Flexibility
In systems with long loop lengths or high current requirements, ZP755 sounders may be powered from an external power supply. All ZP755 sounders incorporate switch settings enabling them to be assigned a unique address which is polled by the panel every 2 seconds. Continuous, intermittent and two-tone outputs are available from which any combination can be chosen to provide alert and evacuate, two stage alarms. All sound types comply with BS5839 Part 1 recommended frequencies.
Sounder enclosures are of molded, high impact, red thermoplastic designed for surface wiring.
