Product Overview

Available in two versions for smoke or heat detection, the FireAngel Pro mains powered radio-interlinked alarms feature a 10 year sealed back-up battery to continue powering the units after a mains failure. The built-in radio-frequency technology enables up to 50 alarms to be wirelessly interlinked within the same system. Providing the earliest possible warning of fire, if one radio-interlinked alarm detects smoke or heat, all other alarms within the same system will also activate.

  • Suitable for installations complying to BS 5839-6: 2013 Grade D, E and F
  • Kitemarked to BS EN 14604 (optical smoke) and BS 5446-2 (heat alarm)
  • Built-in radio-frequency technology allows wireless interlinking
  • A maximum of 50 radio-interlinked alarms can be interlinked
  • 230V mains powered with 10 year sealed lithium back-up battery
  • No need to replace back-up battery for the life of the alarm
  • Available in two versions:
    • WST-230: Optical smoke alarm - for hallways, living rooms and bedrooms
    • WHT-230: Heat alarm - for kitchens and garages
  • Radio-frequency range: 200m in free space, up to 35m in buildings
  • Sold as single units
  • Safelincs Exclusive 5 Year Warranty
  • Loud 85dB warning alarm
  • Test, hush and "Sleep-Easy" function
  • Locate function: allows you to find the alarm that activated the system
  • An interlinked system provides the earliest possible warning of fire
  • Alarms sold separately

In a wireless-only system the maximum number of compatible units that can interlink is 50, while a hard-wired-only system is limited to 30 units. In a mixed hard-wired and wireless alarm system these maximum quantities can be exceeded.

For each "group" of hard-wired alarms in a system, only one should be a wireless model. For example, in a 3 storey house you could hard-wire 2x ST-230 and 1x WST-230 alarms together on each floor with all of the WST-230 models wirelessly interlinked to each other. This can technically be done to a maximum of 50 groups of 30 alarms, though FireAngel has not designed, optimised, or tested these alarms for such a large system. Having so many alarms interlinked would create large communication delays between the alarms, potentially resulting in occupants not being given adequate warning of a fire. It is heavily recommended that customers desiring a large amount of alarms for a single property instead look into full Fire Alarm Systems which are designed for larger premises.

The tables below show all the units that can interlink with the FireAngel Pro Wi-Safe 2 alarms.
