The FireAngel Pro ST-230 optical smoke alarm is mains powered with a 10 year sealed 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 interconnected (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 interconnected, if the ST-230 smoke alarm is activated, it triggers all other linked alarms to also sound.

Q. Do I need an ionisation or optical smoke alarm?
A. We recommend using an optical smoke alarm in hallways, as these are less likely to go off because of cooking fumes from a connected kitchen. Optical smoke alarms are also ideal for living rooms, dining rooms, bedrooms, as they are good at detecting smouldering fires from soft furnishings. For landings we recommend ionisation alarms. Heat alarms are designed for kitchens and garages. No alarms should be installed in bathrooms.
Q. Why do your mains powered alarms have batteries?
A. All our mains powered alarms have a battery backup. Although mains powered alarms without this option do exist (BS5839 part 6 grade E), we regard them as far too dangerous, as a lot of fires are caused by electrical faults leaving the building unprotected against fire if the smoke alarms have no backup battery. With our mains powered alarms you will always be protected.
Q. Can I put my smoke alarm on the wall, or must it be mounted on the ceiling?
A. The best location to install your smoke alarm is in the centre of the ceiling rather than on the wall. During a fire, smoke initially rises and then spreads to the sides of the room. By installing the alarm on the ceiling, this ensures that you receive the earliest possible warning of a fire.
Q. How long do smoke alarms last before needing replacement?
A. It is recommended that smoke alarms are replaced after 10 years. This is because the sensors in the smoke alarms become less sensitive and may not activate when a fire is present.
Q. How long do the batteries last in smoke alarms?
A. 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.
Show all FAQs
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.
