Description

Silent Knight SD505-APS photoelectric smoke detector compensates automatically for contamination in the environment. Also, detector testing is simple even from a remote site. Like other IntelliKnight detector models, the SD505-APS offers a low profile for pleasing aesthetics. Furthermore, the IntelliKnight family of detectors designed to use a common base, Model SD505-6AB, allowing complete application and placement flexibility. Additionally, combine all this with the features you’ve come to expect from Silent Knight smoke detectors easy installation, stable operation, RF/transient protection, and vandal-resistant locking and it adds up to a flexible solution for all your fire protection needs.

The SD505-APS suited to detecting dense smoke typical of fires involving materials such as soft furnishings, plastic, foam or other similar materials which tend to smolder and produce large visible particles. The detector features automatic compensation for contamination as well as a simple detector calibration test procedure that can be run from the panel or remotely (using the WindowsTM based downloading software).

The Silent Knight SD505-APS units made up of an LED light source and a silicon photo diode receiving element. In addition, a normal standby condition, the receiving element receives no light from the pulsing light source. In the event or fire, smoke enters the detector and light reflected from the smoke particles to the receiving element.
