The Edwards 2251TFB is an analog photoelectric smoke as well as a heat detector. Also, the 2251TFB is a plug-in type smoke sensor that combines a photoelectronic sensing chamber with addressable-analog communications. Besides, the sensor transmits an analog representation of smoke density over a communication line to a control panel. Rotary-decade switches are provided for setting the sensor’s address. Two LEDs on the sensor are controlled by the panel to indicate sensor status. An output is provided for connection to an optional remote LED annunciator.
In general, the Edwards 2251TFB features a fixed temperature (135°F) heat detector. The detector requires compatible addressable communications to function properly. Furthermore, connect these sensors to the listed compatible control panel only. This sensor must be install in compliance with the control panel system installation manual. In addition, the installation must meet the requirements of the Authority Having Jurisdiction. Sensors offer maximum performance when installed in compliance with the National Fire Protection Association.
