Provides early detection of smoke and products of combustion present in air moving through HVAC ducts in Commercial, Industrial and Resident applications.

The Napco FWCFSLCHEAT sensor provides accurate temperature measurement data to the fire alarm control panel.

It's particularly suited to detecting optically dense smoke typical of fires involving materials such as soft furnishings, plastic, foam etc.

The Napco FWCFSLCSMK6B bases are designed specifically for use with the Napco Analog models FWCFSLCSMK and FWCFSLCHEAT.

The GEMCWLHEAT is a high-quality wireless 135°F (57°C) fixed-temperature heat detector with Rate of Rise.

The GEMCWLSMK is a high-quality photoelectric smoke detector with built-in supervised digitally coded radio tramsnitter.

Wireless dual input transmitter; ideal for pull stations and sprinkler supervisories

The CPS-24 can be used in all open areas where Photoelectric Smoke Detectors are required, including in-duct applications.

Silent Knigh KNI-PTIR-W Multi-Criteria Detector.

The PTIR Sensors by System Sensor are multi criteria sensor which includes photoelectric, thermal & infra red sensor. Offers better performance over the alternative technologies of dual angle or dual wavelength optical detectors &photo-thermal detectors.

The SKHEAT is a fixed temperature sensor that uses a thermistor sensing circuit to product a 135⁰F fixed temperature alarm.

The SKHEATHT is a variable high temperature detector that provides high temperature detection at 135⁰F - 190⁰F.

The SKHEATROR is a rate-of-rise temperature sensor with 135⁰ fixed temperature alarm.
