Notifier NFXI-TDIFF-BK Addressable Thermo-differential Detector Black

The NFXI-TDIFF-BK is an addressable thermo-differential detector from Notifier in the colour black. The detector is integrated in an analogue fire alarm system. This means that an alarm can be triggered locally instead of the entire system going into alarm. In addition, the detector is equipped with an isolator which ensures that the rest of the detectors continue to function if they have a single fault. The NFXI-TDIFF-BK is a themo-differential detector that detects heat and its speed. When maximum heat and temperature rise is detected, the alarm sounds. The NFXI-TDIFF-BK is a themo-differential detector that detects heat and its velocity as soon as the maximum heat and temperature rise is detected, the alarm sounds.

The NFXI-TDIFF-BK is equipped with two LED indicators that show the status of the optical and thermal detector. Green indicates normal functionality, orange indicates fault or test mode, and red indicates alarm. The detector is compatible with a wide range of sockets, which may have a siren or flash built in. The standard base unit for NFXI-TDIFF-BK is B501AP-BK.

Product Questions

After how many years do I have to replace an old fire detector with a new one?
Question by: Wolfgang on Jun 7, 2025, 1:22 PM
A fire detector (smoke / heat detector) should generally be replaced every 10 years. This is the standard service life of most smoke detectors, including those from Jablotron, Notifier and DSC.

Why replace after 10 years?
> Sensor ageing: The smoke detector loses its sensitivity over time.
> Battery wear: Even models with long-life batteries can run out after 10 years.
> Reliability: After 10 years, the risk of faults increases and security systems must always be reliable.
