The ST-750T features FireAngel's groundbreaking Thermoptek technology, when the alarm detects a rise in temperature the optical sensor becomes extra sensitive, making it able to detec fires much faster than standard optical alarms. Powered by a sealed Panasonic lithium battery, the ultimate in battery life reliability, there is no need to change the alarm's battery for its entire 10 year lifespan – while the "Sleep Easy" function allows homeowners to silence the end-of-life chirp for 8 hours to avoid being disturbed while asleep. The Alarm Smart Silence feature will help ensure the safety of building occupants by overriding a manual silence before the end of the standard 10-minute window if high levels of smoke remain. FireAngel's Thermoptek smoke alarms are recommended by the UK's Fire and Rescue Service.

Q. What smoke alarm should I use in a bedroom with an en suite bathroom?
A. 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 than can original from upholstery type materials and over-heated wiring. Also, an optical smoke alarm would be less likely to sound a false alarm than what an ionisation would do 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?
A. 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. 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.
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. Can a smoke alarm be fitted with a sticky adhesive pad in a let property?
A. The sticky pad is suitable for all battery operated smoke alarms. However, we cannot judge if battery alarms are suitable for your let property, as let properties usually require mains powered alarms. There is some advice to this in the governments guides to fire risk assessments. http://www.safelincs.co.uk/Fire-Risk-Assessment/
Also see the LACoRS guide for let properties.
Q. What sort of smoke alarm system would I need to install for a HMO?
A. 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.
