22051TE-26 System Sensor Multisensor with Isolator

The Series 200 Advanced range represents a significant advancement in detector technology, offering a new platform with the Series 200 Advanced Protocol. This protocol enhances the capacity of devices on the loop, providing improved control, configurability, and device management. It allows for greater flexibility in optimising the system to suit the specific needs and uses of a building.

A key feature of this range is the 22051TE Photo Thermal detector, a multi-criteria multi-sensor device. It combines thermal assistance with a photoelectric smoke detector, improving immunity to false alarms while offering quicker response times to various types of incipient fires. This plug-in unit is equipped with two separate sensing elements, integrated by embedded software to function as a single, cohesive unit. The 22051TE is compliant with EN54-5 standards for a 58°C fixed temperature and rate of rise thermal detection, as well as EN54-7 standards for smoke detection.

The thermal detection within the 22051TE uses thermistor technology, which is enhanced by software to provide a corrected linear temperature response. In settings where routine activities could trigger false alarms, the detector can be set to "heat only" mode during active hours, automatically switching back to full photo-thermal detection during inactive periods.

Additionally, the 22051TE’s sensing elements can be controlled by the panel, allowing sensitivity thresholds to be adjusted according to the changing requirements of the protected area. The detector also features two built-in tri-colour LEDs that offer 360° visual indication of device status, with programmable static or blinking red, amber, and green indications.

The Series 200 Advanced detectors are designed with environmental considerations in mind, adhering to WEEE and RoHS legislative standards to reduce disposal costs at the end of their lifecycle. They are also backward compatible, both mechanically and electrically, with existing Series 200 plus devices.

Key Features:

• Multi-criteria detection using photoelectric smoke and thermal sensors.
• Programmable modes to reduce false alarms.
• Tri-colour LEDs provide 360° visual status.
• Environmentally friendly, RoHS, and WEEE compliant.

Applications:

• Ideal for commercial and industrial fire detection systems.
• Suitable for areas with varying environmental conditions.
