The FireAngel Pro ST-230 optical smoke alarm is mains powered that has a 10 year lifespan with a sealed lifetime lithium back-up battery. Designed to last the life of the alarm, the back-up battery continues to provide power in the event of a mains failure. The ST-230 smoke alarm can be interlinked (using cable) with up to 30 smoke and heat alarms from the FireAngel Pro series, providing wide coverage within a single smoke alarm system. Once interlinked, if the ST-230 smoke alarm is activated, it triggers all other linked alarms to also sound.
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 table below shows all the units that can interlink with the FireAngel Pro alarms.

BS 5839-6 recommends that one or two storey HMOs with an individual floor area of no more than 200sqm (not the total of both floors) should have a Grade D smoke alarm system installed. Grade D refers to mains powered smoke alarms with a back up battery power supply. The alarms can be interlinked either by wire or by radio signal and the system does not require a separate fire alarm panel. For HMOs of 3 storey or higher, a Grade A panel system would need to be installed. This can cover the whole of the building, or can be used just for the communal areas with a separate Grade D system installed for the individual dwellings. For both applications, the level of cover should be a minimum of LD3 (in all escape routes) but this may change according to the fire risk assessment.
Every FireAngel FAST230 is supplied with the following components.

More expensive than standard smoke detectors, but have good features Got three of these (two link together, wired). They were fitted by an electrician so I can't comment on that but it seemed easy enough. Note that the screws fitting the plate to the ceiling need to be recessed or they'll interfere with the working of the unit. These are neat and smart-looking. I wanted to fit these and not worry about them again (no replacing of batteries). I was a little disappointed that one of the units did develop a fault within a couple of weeks, but Safelincs were excellent and sent a replacement.
