Notifier FDX-551HTEM Heat Detector – Fixed Temperature – Now Obsolete

The Notifier FDX-551HTEM was an analogue addressable fixed temperature heat detector.  This detector had a fixed temperature setting of 78 degrees celcius.  The Notifier FDX-551HTEM is now obsolete and has been replaced by the Notifier NFX-TFIX78-IV.  This sensor has the same ivory colour as the old sensor and is backwards compatible so it can be used as a direct replacement for the old device.  It uses the same B501 range of detector bases, so the base doesn’t need to be changed.  For more information on the Notifier FDX-551HTEM call us NOW on 01200 428 410.

Along with the heat detectors we can also supply the full range of European Notifier protocol detectors.  This range includes smoke, heat and multi-criteria sensors suitable for use on Notifier protocol analogue addressable fire alarm control panels.

The Safety Centre can also offer a commissioning service for Notifier Fire Alarm Systems.
