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.
Power: 230V mains powered with a lifetime lithium back-up battery
Backup Battery: Built-in battery lasts the lifetime of your alarm
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.
Q. What smoke alarm should I use in a bedroom with an en suite bathroom?
It is usually recommended to install an optical smoke alarm in a bedroom. This is because optical smoke alarms are slightly quicker at detecting slow smouldering fires that can originate from upholstery type materials and over-heated wiring. Also, an optical smoke alarm would be less likely to sound a false alarm than an ionisation would, if steam/water droplets were present from the bathroom. Detectors should be installed as central to the room as possible; however for your application I would also consider the position of the en suite to make sure that the detector is not in the direct path of the joining door. This is just to try and avoid the chances of a false alarm. No detector is designed for use in bathroom areas.
Q. How do I safely dispose of my old smoke alarms?
Safelincs is signed up to Valpak's WEEE (Waste Electrical and Electronic Equipment) Distributor Take-Back Scheme (Registration ID: 7370). Private households can therefore drop off their electronic and electrical fire safety waste at their municipal recycling centre when they are purchasing new products from us. To find your nearest recycling centre, please visit www.recycle-more.co.uk.
Q. Can the mains powered smoke alarm range be connected to mains power via the lighting circuit?
Yes, hard-wired mains powered alarms can be wired to the unswitched live feed of the nearest frequently used lighting circuit.
Q. How long do the batteries last in smoke alarms?
The 9V alkaline batteries last 12-18 months. Lithium batteries will usually last 5x longer than their alkaline counterparts, achieving around 5 years lifetime. Some lithium cells are also rechargeable, and when used in a mains-powered alarm may last for the entire functional lifespan of the alarm. Newer alarm models may also feature a "sealed" lithium battery. These batteries are specialist components which are designed to not be removed or need replacing by the user, and have been tested by the alarm manufacturer to ensure they last for the lifetime of the alarm.
Please Note: the actual lifetime of your batteries depends on how often the alarms are tested or activated, as sounding the alarm draws more power than when the alarms are "waiting" to detect fire. You should also read your alarm's manual to make sure you only use the recommended types and brands of batteries, as failing to follow these instructions may cause the alarm to malfunction, not alerting you in the event of a fire, and might also invalidate the warranty.
Q. If a false alarm goes off can pressing the hush button on any of the interlinking alarms stop all the units beeping?
No, to stop the alarms from sounding the hush button on the unit that started the process needs to be pushed. Pressing any other unit will just silence that one unit. The unit can be identified by the rapidly flashing red LED.

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.
