Nittan ST-P-OM Photoelectric Detector
Nittan ST-P-OM Photoelectric Detector 4 TerminalUsing a simple but effective technique the ST-P-OM Optical Detector incorporates a chamber housing an Infra-Red IR LED light and a photodiode light detector set at an obtuse angle preventing it from seeing the light. When smoke enters the chamber the light bounces off the smoke particles and strikes the photodiode causing it to generate an alarm condition when a set threshold value is met.The ST-P-OM Optical Detector is therefore more sensitive to larger smoke particles which tend to be caused by smouldering fires rather than fast flaming fires.Key FeaturesOptical Smoke DetectorOmniview 360 LEDSC Alarm characteristicWide operational voltage range 12v - 32v
