Audible and visual warning from a single unit
The ZP755BV-4P is a POLAR WHITE, addressable loop powered base sounder with visual indicator for us on ZP fire alarm systems. The ZP755BV combines a detector base, audible sounder and high intensity visual indicator in a single stylish moulding. It offers both audible and visual warnings from a single, addressable, loop wired unit.
Providing an elegant solution for areas where the installation of a separate detector, sounder and visual indicator would prove expensive, both in equipment value and system wiring costs, the unit meets the requirements of most local legislation. Installation time is further reduced as the moulding plugs directly onto a first fix base, eliminating the need for any internal connections.
The ZP755BV is perfectly suited for any location involving high levels of background noise.
Low current sound gun and visual element
Independent addressing for the detector and alarm facilities is featured, with sound levels conforming to EN54 Part 3 and clear visual indication provided by a high intensity LED array positioned inside the base moulding.
High efficiency acoustic design, a low energy sound gun transducer and a low current visual element enables up to 30 detector and ZP755BV combinations to be connected to a 1 km loop of 1.5 mm² cable, with a wiring run of 50 m to the first device.
The range features a unique self test facility that is automatically activated during routine sounder testing. A built-in microphone circuit measures sound output and automatically signals the sounder address and location to the control panel, should the output test fail
External power supply option
The ZP755BV may be used with other ZP loop equipment in any combined application subject to maximum loop loading. In systems where loop lengths or current requirements are excessive, the ZP755BV may be powered directly from an external power supply.
With a sound output of 90 dB(A), continuous, intermittent and two-tone audible outputs are available. The volume setting can be reduced for areas where a lower sound level is required
