IntelliKnight 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 SD505-PHOTO photoelectric detector has a unique address, which is recognized by the IntelliKnight panel. Wasting no precious seconds in determining location of an alarm.

The SD505-PHOTO compensates automatically for contamination in the environment. And detector testing is simple—even from a remote site. Like other IntelliKnight detector models, the SD505-PHOTO offers a low profile for pleasing aesthetics. The IntelliKnight family of detectors has been designed to use a common base, Model SD505-6AB, allowing complete application and placement flexibility.

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-PHOTO is particularly efficient at detecting dense smoke typical of fires involving materials. Such materials include soft furnishings, plastic, foam or other similar materials which tend to smolder and produce large visible particles.
