    Zeta Intrinsically Safe Programmable Heat Detector

    The ZIS-PHD heat (temperature) detector is designed to detect a fire hazard in rooms, where during the first phase of a fire a rapid rise of temperature may occur, or where temperature may exceed a defined danger level.

    The ZIS-PHD is a universal heat detector, which can be programmed to operate as a fixed temperature or fixed/ rate-of rise heat detector. It is also possible to change the class of these detectors adapting them to specific applications. The PN-EN 54-5 European standard allows a choice of one of the following classes of detector sensitivity: A1R, A1S, BR or BS.

    The ZIS-PHD is a spark proof detector, due to which it can be used in explosion hazard areas. These detectors operate in Zeta manufactured fire alarm system detector Dimensions (mm) & Weight (kg) lines behind a proper spark proof separator.
