Notifier Intelligent Photoelectric and Temperature Sensors
Model Number: FSP-951T
Models FSP-951T and FSP-951T-IV are plug-in type multi-sensor smoke sensors that combine a photoelectronic sensing chamber and 135°F (57.2°C) fixed temperature heat detector across addressable-analog communications. The sensors transmit 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. (See Figure 1.) The intelligent photoelectric and temperature sensors also transmit an alarm signal due to heat at 135°F (57.2°C) per UL 521.
