Analogue thermal sensor - ZP720-3
The ZP720-3 analogue thermal sensor is a thermistor controlled device that responds to changes in its ambient temperature.
Description
The device provides a reliable response to fires in areas where environmental conditions may prohibit the use of smoke sensors.
The sensitivity of each sensor is set by the ZP control panel and can be adjusted between four levels - from 58ºC to 75ºC - either manually or automatically on a timed basis. At sensitivity level two, the ZP720-3 fully meets the requirements of European Standard EN 54 Pt 5 (grade 1) and is approved by several international approval bodies. Temperature levels are continuously sensed by the unit and transmitted via the ZP wiring loop as electronic signals, which are assessed and verified by the control panel prior to any alarm decision being taken.
