Ziton Z620 Conventional Heat Detector
Based on advanced thermistor technology, the Ziton Z620 series of heat detectors, provides a reliable response to fires in areas where environmental conditions prohibit the use of smoke detection.
The Ziton Z620-581 is a fixed temperature model, operating at 58oC. It is intended for applications where fluctuations of ambient temperature may be expected for example, over machinery in laundries, or factory locations where industrial processes may cause sharp temperature increases.
The Ziton Z620-582 operates on the rate of rise of its ambient temperature. To increase response time, without compromising reliability, a rate compensation element enables the detector to become more sensitive to higher rates of temperature rise.
High temperature version
Z620-771 is a high temperature detector suitable for use where ambient temperatures may consistently be greater than normal, for example boiler rooms and certain food processing installations. The detector is set to operate at 82oC.
The Z620-581 and Z620-582 detectors meet the requirements of EN 54 Part 5 with sensitivity to grade 2 and grade 1 respectively. The high temperature version complies with EN 54 part 8 with range 1 sensitivity.
Low profile moulding and options of either surface or recessed bases make the units ideal for both modern commercial and industrial interiors, featuring solid or suspended ceilings. A high intensity, red LED indicator on the detector moulding provides clear indication when the unit is in alarm.
Twist and lock base
For ease of removal, Z620 detectors plug into a range of base units. In order to prevent unauthorised removal, a site selectable option is provided to lock the detector into its base. Once applied the unit can only be removed by means of a special tool.
All Z620 detectors feature head out monitoring. Should a detector remain removed from its base, in addition to giving a fault signal, all devices down line of the removed unit continue to function normally.
