Photoelectric Detectors Dealers in Sunder Vihar, Delhi (2 products available)

System Sensor 200 Series intelligent plug-in smoke detectors with integral communication provide features that surpass conventional detectors. Detector sensitivity can be programmed in the control panel software. Sensitivity is continuously monitored and reported to the panel. Point ID capability allows each detector’s address to be set with decade address switches, providing exact detector locations for selective maintenance when chamber contamination reaches an unacceptable level. Model 2251B photoelectric detector’s unique optical sensing chamber is engineered to sense smoke produced by a wide range of combustion sources. Dual electronic thermistors add 135°F fixed temperature thermal sensing on the 2251TB.
