Morley 22051TEI-26 Optical/Thermal Sensor + Isolator

The 22051TEI-26 is a Morley Addressable Devices optical/thermal multi sensor with isolator from the Addressable Detection range, specifically designed as a detector within the S200A series. It combines an optical smoke sensor and a thermal sensor in a single white housing, featuring an integral isolator to maintain loop integrity during fault conditions. This design helps ensure the addressable loop remains operational even if a short circuit occurs at the sensor point.

The device is engineered for mounting exclusively on the B501AP base, as specified in its compatibility requirements. Its core specification includes a white colour finish, consistent with Morley's addressable detection product line. For detailed physical connection guidelines, users should consult the associated installation manual. The integral isolator function provides critical resilience by isolating faulty sections without disrupting communication across the broader loop, enhancing overall system reliability in addressable fire detection applications. This multi-sensor approach improves detection accuracy by responding to both smoke and heat signatures, reducing false alarms while maintaining sensitivity to developing fire conditions. The white housing helps ensure visual discretion when installed in commercial or public environments where aesthetics are a consideration alongside performance. Compatibility with the B501AP base helps ensure secure mechanical attachment and proper electrical interfacing for integration into existing Morley addressable systems. Referencing the installation manual helps ensure correct wiring practices and adherence to safety standards during deployment. These combined features position the 22051TEI-26 as a dependable component within life-safety infrastructure, supporting continuous loop functionality even under adverse electrical fault scenarios.
