Apollo Orbis Intrinsically Safe A1S Heat Detector with Flashing LED (ORB-HT-51158-APO)
The Orbis IS Heat Detector monitors temperature by using a single thermistor network which provides a voltage output proportional to the external air temperature. The Orbis IS range incorporates seven heat detector classes to suit a wide range of operating conditions.
Installation:
It is important that the Orbis I.S. detectors be installed in such a way that all terminals and connections are protected to at least IP20 when the detector is in the base. Special care must be taken with the rear of the mounting base where live metal parts may be accessible.
Flush mounting of the base on a flat surface will provide the required degree of protection. The conduit box available from Apollo, part no. 45681-204, is also acceptable for mounting I.S. bases. Apollo also supply a range of deckhead mounting boxes.
