The addressable photoelectric smoke detectors are the clear choice for commercial settings where smoldering fires are a threat. In addition to accurately detecting a smoldering fire, each Silent Knight SD505-PHOTO photoelectric detector has a unique address, which is recognize by the IntelliKnight panel. No precious seconds are wast in determining the location of an alarm.
The Silent Knight SD505-PHOTO Detector is particularly suit to detecting dense smoke typical of fires involving materials such as soft furnishings or other similar materials that tend to smolder and produce large visible particles. Moreover, the detector features automatic compensation for contamination and a simple detector calibration test procedure that can be run from the panel or remotely.
Furthermore, the Silent Knight SD505-PHOTO Detector units made up of an LED light source and a silicon photodiode receiving element. In a normal standby condition, the receiving element receives no light from the pulsing light source. In the event of a fire, smoke enters the detector, and light reflects from the smoke particles. The light received is convert into an electronic signal. Under normal conditions, the status LED blinks approximately every 15 seconds, indicating that the Head is communicating with the loop. The LED lights continuously during the alarm period.
Also, the SD505-PHOTO shall automatically perform a functional test of the detector. The test method shall simulate the effects of products in the chamber to ensure the testing of detector circuits.
