ATD-L2F/RL2F/HL2F Thermal Sensor

The ATD-L2F, ATD-RL2F, AND ATD-HL2RF are addressable thermal sensors that utilize a state of the art thermistor sensing circuit for fast response. The ATD-L2F is a fixed temperature sensor that uses a thermistor sensing circuit to product a 135⁰F fixed temperature alarm. The ATD-RL2Fprovides a combination 15°/minute rate-of-rise temperature sensor with 135⁰ fixed temperature alarm. The ATD-HL2F is a variable high temperature detector that provides high temperature detection at 135⁰F - 190⁰F. Compatible with E3 Series, S3 Series, and 7100 Series addressable fire alarm control panels.
