Early response to slow burning fires

Designed to provide smoke detection on ZP3 systems, where the installation of hard wiring is not an option, the ZR430 wireless optical smoke sensor provides an early response to slow burning fires. The unit is controlled directly from the main control 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. Operating on light scatter principles, the ZR430 fully meets the requirements of European Standard EN54 Part 7.

Four sensitivity levels

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 is assigned its own IDENT address, with which the main control panel communicates, providing the same system facilities as for directly wired devices. False and unwanted alarms are virtually eliminated - smoke levels are continuously sensed by the unit and transmitted to the radio loop module, which in turn relays the data to the main control panel. Four levels of sensitivity can be set, by selection switches on the sensor base plate. Calibration and self-test are carried out automatically. Removal or replacement of an incorrect sensing device is identified by the system and details displayed at the main control panel. Sophisticated auto contamination adjustment, compensates for any long-term drift in performance caused by dirt entering the sensing chamber.

Plug in base

For ease of removal sensors plug into the ZR400 radio base by a simple twist and lock action. Bases are installed using a matching fixing plate. A red LED indicator situated on the sensor moulding flashes to indicate when the unit is in alarm.
