Life Safety Consultants stocks a wide selection of smoke detectors for commercial fire alarm systems. Our inventory includes intelligent addressable smoke detectors, conventional smoke detectors, and detector bases from leading manufacturers including Notifier, Simplex, Siemens, and more. Whether you need a single replacement device or a bulk supply for a large installation, we can help.

Smoke detectors are the frontline of any fire alarm system. They detect the earliest signs of combustion — long before a fire becomes visible — giving building occupants time to evacuate safely and enabling fire suppression systems to activate. In commercial buildings, schools, healthcare facilities, and industrial sites, properly maintained smoke detection is required under NFPA 72 and local fire codes.

Our smoke detector inventory includes intelligent low-profile detectors such as the Notifier FSP-951 and FSP-851, which are compatible with Notifier addressable fire alarm control panels. We also carry a variety of compatible detector bases including the Notifier B300-6 and B210LP, which mount the detector to a standard electrical backbox.

When selecting a replacement smoke detector, it is important to match the device to your existing fire alarm control panel. Addressable detectors communicate on a signaling line circuit (SLC) and require panel compatibility. Our team can help you confirm the right part for your system.
