Earliest response to a wide range of fire types

Designed to provide the earliest response to a wide range of fire types, in locations where hard wiring is not an option, the ZR432 wireless sensor combines optical smoke sensing and thermal monitoring to provide an accurate warning of fire.

Individual monitoring of each element, measures actual smoke levels, in addition to temperature rates of rise. When installed using the ZR401 base the sensors operation can be selected as either smoke or heat. The ZR402 base enables the unit to operate as a multi sensor utilizing both smoke and heat channels.

Smoke sensing can be isolated for areas where ambient smoke may exist at certain times of the day, or used on a day night basis in premises where heat only is required whilst the building is occupied. Temperature response meets the requirements of European Standard EN54 Part 5. (Settable to grade 1 or grade 3), with smoke sensitivity complying with EN54 Part 7. The sensor is approved by several international approval bodies.

Controlled directly from main control panel

The unit is controlled directly from the main control panel, via a loop wired radio interface module. Up to 127 devices can be connected to each of the control panel loops, allowing both wireless and hardwired devices to be seamlessly located and controlled from the same wiring loop. Each wireless device, controlled through the ZR470 radio interface unit, is assigned its own IDENT address, with which the main control panel communicates, providing the same system facilities as directly wired devices.

Automatic self test

Temperature and smoke sensitivity can be set by selection switches located on the base plate of the unit, 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. For ease of removal sensors plug into the ZR400 series radio bases by a simple twist and lock action.
