Description
Model 2351TB is a plug-in type multi-sensor smoke sensor which combines a photoelectronic sensing chamber and 135°F (57.2°C) fixed temperature heat detector across addressable-analog communications. The sensor transmits an analog representation of smoke density over a communication line to a control panel. Rotary dial switches are provided for setting the sensor’s address. The intelligent photoelectric and temperature sensor also transmits an alarm signal due to heat at 135°F (57.2°C) per UL 521.
