Visual alarm beats noise pollution

June 2004 Fire & Safety

Across the world disability legislation increasingly requires visual alarm signals to be employed to ensure equal response from people with hearing impairment. The ZP755HAV from Ziton is perfectly suited for this application and indeed any involving high levels of background noise.

It provides both audible and visual warnings from a single, addressable, loop wired unit.

Featuring an identical profile to the ZP755 HA horn sounder, the ZP755HAV can minimise the number of installation points required throughout a building, significantly lowering both the capital value of equipment and the loop wiring costs of the completed system.

Installed directly onto and powered by the ZP wiring loop, ZP755 HAV enables the system designer to offer a complete ZP3 analog addressable system on a single pair of wires.

The unit's high efficiency acoustic design, low energy sound gun transducer and low current light emitting diode (LED) visual element, enables combinations of up to 100 sensors and 40 sounder beacons to be connected to a one-kilometre loop of 1,5 mm2 cable.

With a low current consumption the ZP755 HA sounder and ZP755HAV sounder/beacon can be used in any combined application provided the maximum loop loading is not exceeded.

In systems where loop lengths or current requirements are excessive, ZP755HAV sounder beacons can be powered directly from an external power supply. All ZP755 units incorporate switch settings enabling them to be assigned a unique address, which is polled by the panel every two seconds.

Continuous, intermittent and two-tone audible outputs are available, from which any combination can be chosen to provide alert and evacuate, two stage alarms. All sound types and flash rates comply with BS 5839 Part 1 recommended frequencies.

The ZP755 HAV produces a sound output of 102 dBA, tested at 1 metre. A volume control is included for areas where a reduced sound output is required.
