ZR454 wireless Alarm sounder

The ZR454 wireless alarm sounder is designed for surface fixing has no aerials external to its enclosure and is supplied complete with matching back box. Rated at IP42 the ZR454 is constructed of ABS plastic and is intended for indoor applications.

Dual power source
The unit's high output features selectable tone patterns, with outputs of 96 dBA measured at 1 metre. Four different tones provide signals for alert, evacuate, security alert and class change. Power is derived from two independent, separate battery sources.

Highest signal integrity
To ensure the highest signal integrity the unit transmits its quiescent and fault signals to the loop module by VHF radio communication, but is switched to its operating mode by the receipt of a powerful UHF signal direct from the loop module. Installed as part of the ZP3 analogue addressable system, up to 127 devices can be connected to each of the control panel loops. Each wireless device, controlled through the ZR470 interface is assigned its own IDENT address, with which the main control panel communicates, providing the same system facilities as directly wired devices.

The sounder forms part of an extensive range of wireless fire alarm devices, which includes smoke/heat sensors in addition to manual callpoints. Suitable for applications specifying the recommendations of BS 5839 Part 1, the ZR454 can be addressed as a stand alone unit, operating in isolation by signals from its programmed inputs, as part of a sounder group where several units in the same location are synchronized to operate simultaneously, or be operated by both arrangements.

Sounders are controlled directly from the main fire alarm panel, via a loop wired radio interface module. This arrangement allows both wireless and hardwired devices to be seamlessly located on the same loop wiring.

Control via interface module
ZR454 wireless alarm sounders provide a range of warning tones in areas where the installation of hard wiring is not an option.
