Ziton ZP720-3 Analogue Heat Sensor

Ziton ZP720-3 Analogue Heat Sensor


Product Code: 101501

Please Contact Us for Price & Availability.

Contact Us

The ZP720-3 is being phased out, and is going to be replaced by the ZP720-3P


Ziton ZP720-3 Analogue Heat Sensor


  • Analogue sensing - reduces false and unwanted alarms
  • Addressable - system knows the status and location of every sensor
  • Automatic self test
  • EN54 Part 5 approved

Reliable sensing for most fire alarm applications

The ZP720-3 analogue thermal sensor is a thermistor controlled device which responds to changes in its ambient temperature. 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 58?C to 75?C 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.

Automatic self test

Sensor sensitivity, calibration and self test are carried out automatically by the ZP3 system. Removal or replacement of an incorrect sensing device will be identified by the system and shown as a fault.

Up to 127 sensing devices can be connected to each of the control panel loops. All loop devices incorporate switch settings enabling them to be given a unique address, which is polled by the panel every two seconds.

Locking base option

The low profile moulding together with either surface or recessed bases makes the unit ideal for both commercial and industrial interiors. A red LED indicator situated on the sensor moulding, flashes to indicate when the unit is in alarm.

For ease of removal sensors plug into a range of base units by a simple twist and lock action. A site selectable option is provided to lock the sensor into its base. Once applied the unit can only be removed by means of a special tool.

Space for address labels is provided on sensor and base mouldings - ensuring units are replaced in their correct location and address numbers can be identified from floor level.
