Based on advanced thermistor technology, the Z620 series of heat detectors, provides a reliable response to fires in areas where environmental conditions prohibit the use of smoke detection.
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.
The Z620-582 detectors meet the requirements of EN 54 Part 5 with sensitivity to grade 1.
Requires the (BS1 base) for installation.
