Conventional Detectors Detector Range
Photoelectric smoke detector (opto) is suitable for most applications giving the fastest response to slow burning or smouldering fires which give rise to large visible smoke particles.
Photoelectric smoke detector (opto) is suitable for most applications giving the fastest response to slow burning or smouldering fires which give rise to large visible smoke particles.
Opto-heat detector will respond better to fast clean burning fires yet maintain the advantage of optical detectors when detecting smouldering fires. The thermal enhancement of this detector allows a higher alarm threshold which provides a greater rejection of false alarms. The detector will also raise an alarm at temperatures above 135°F.
Rate of Rise detector and Fixed Heat detector will detect a rapid increase in temperature or temperatures above 135°F or 194°F (dependent on switch selection) and should be used in environments where the ambient conditions might cause false alarms if smoke detection were to be used, for example where there is a high level of dust, fumes, steam or smoke under normal conditions.
Features
