System Sensor 2251B Photoelectronic Addressable Smoke Detector

The SYSTEM SENSOR 2251B Intelligent Photoelectric Sensor is a high-quality plug-in type smoke sensor that utilizes a photoelectronic sensing chamber combined with addressable-analog communications. It transmits an analog representation of smoke density to a control panel over a communication line, ensuring accurate and reliable fire detection. The sensor's rotary-decade switches allow easy setting of the sensor's address for convenient customization. For optimal performance, System Sensor recommends spacing the sensors in accordance with NFPA 72 guidelines. The 2251B sensor is suitable for various applications and can be used as a heat detector when complying with FM3210 requirements. All wiring must be installed following the National Electrical Code and applicable local codes, as proper connections are crucial for the system to respond effectively in the event of a fire.
