Available in two versions for smoke or heat detection, the FireAngel Pro mains powered radio-interlinked alarms have a 10 year life and feature a sealed longlife lithium back-up battery to continue powering the units after a mains failure for the full lifespan of the alarms. 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.

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.
