ORB-HT-11001 Apollo Orbis A1R Rate of Rise Heat Detector 50c




There are six heat detectors in the Orbis range.
The detectors are classified according to EN54-5 as rate-of-rise or static
and are designated 'R' or 'S' accordingly. Static heat detectors will respond only when the alarm threshold is reached.
Rate-of-rise detectors have this fixed upper limit, but also measure the rate of increase in temperature.

Also available with flashing LED (ORB-HT-11013)
