Overview

The Ajax FireProtect 2 SB (Heat) Jeweller is a heat alarm that sounds its built-in 85 dB siren and alerts your Ajax system when the temperature becomes dangerous. It has no smoke sensor, so it suits rooms where smoke, steam or dust would give a smoke alarm false alarms. Its batteries are sealed and rated for 10 years, so there is nothing to change.

Is it right for you?

  • Choose it for a room where a smoke alarm would give false alarms and heat detection is enough.
  • It does not detect smoke. For bedrooms and living rooms, a FireProtect 2 model with a smoke sensor is the better choice.
  • Sealed batteries mean no battery changes for the life of the detector; if you prefer replaceable batteries, see the RB models.
  • Hub (2G) Jeweller is not on its compatibility list; it is listed for Hub (4G), Hub Plus, Hub 2, Hub 2 Plus, ReX and ReX 2 among others.

Key features

  • Heat sensor meeting the requirements for Class A1R heat detectors under EN 54-5 and BS 5446-2.
  • Alarm when the temperature rises above 64 °C, or by more than 10 °C within 1 minute.
  • Built-in siren at 85 dB at 3 m, sounding until the cause is cleared or the user silences it.
  • Interconnected alarm through the hub within 20 seconds, plus a fallback link detector to detector that sounds every connected detector within a minute even if the hub is lost (firmware 5.59.2.XX or later, marked on the package).
  • LED indication: green every 56 seconds for power, yellow for faults such as low battery, red for a fire alarm.
  • Front button runs a self-test in normal mode and silences the siren during an alarm or fault.
  • Jeweller radio to the hub or range extender up to 1,700 m in open space, encrypted with frequency hopping.
  • Two sealed lithium batteries rated for 10 years; 44 x 86 x 86 mm, 142 g.
