Life Safety Consultants stocks System Sensor fire alarm devices including smoke detectors, horn strobes, sounder bases, and remote test stations. System Sensor is one of the most widely recognized brands in commercial fire alarm detection, with products installed in millions of buildings across North America. Their devices are known for reliability, broad compatibility, and ease of installation.

System Sensor manufactures both 2-wire and 4-wire smoke detectors, horn strobes, and combination devices for conventional and addressable fire alarm systems. Their products are compatible with panels from most major manufacturers, making them a popular choice for new installations and replacement parts alike.

Our System Sensor inventory includes the 2W-B Photoelectric Smoke Detector, a 2-wire device compatible with a wide range of conventional fire alarm panels. We also carry the 4WTR-B 4-Wire Smoke and Thermal Detector for applications requiring enhanced detection coverage. For notification, we stock the PC2RLED 2-Wire Horn Strobe (ceiling mount, red) and the P2RLED LED Horn Strobe (wall mount) — both widely used in commercial corridor and office applications. Our sounder base inventory includes the B200S-LF-WH Low-Frequency Sounder Base, which produces a low-frequency tone suited for sleeping areas and high-noise environments. We also carry the B501-WH 4″ Standard Flangeless Base for standard detector mounting.

Additionally, we stock the RTS151KEY Remote Test Station with Key, which allows technicians to test System Sensor smoke detectors from a distance without the need for a test wand or ladder access.
