Velocity® Series Addressable Thermal Sensor

The Gamewell-FCI, Velocity® Series addressable plug-in thermal sensors with integral communication provide features that surpass conventional sensors. Point ID capability allows each sensor’s address to be set, providing exact locations for pinpointing alarm locations and used for selective maintenance. ATD thermal sensors use an innovative thermistor sensing circuit to produce 135°F/57°C fixed temperature (ATD-L2F). The ATD-RL2F provides a combination 15°/minute rate-of rise with 135° fixed thermal detection that is included in a low-profile package. The ATD-HL2F provides fixed high-temperature detection at 190°F/88°C. These thermal sensors provide cost-effective, addressable property protection in a variety of applications.
