In general, the Gamewell FCI ATD-L2F addressable plug-in thermal sensor with integral communication provides 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. Also, the Gamewell FCI ATD-L2F thermal sensor uses an innovative thermistor sensing circuit to produce 135°F/57°C fixed temperature. The ATD-RL2F provides a combination 15°/minute rate-of-rise with 135° fixed thermal detection that is include 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.
Furthermore, the Velociti® Series uses a communication protocol that substantially increases the speed of communication between the sensors and Gamewell-FCI analog addressable fire alarm controls. These devices operate in a grouped fashion. If one of the devices in the group has a status change, the panel’s microprocessor stops the group poll and identifies the single device with the status change. The net effect is response speed up to five times greater than earlier designs.
