Product Overview

The FireAngel SO-601 is a 9V optical smoke alarm with toast proof sensing technology, making it less prone to sound falsely when cooking fumes are present. As the SO-601 is now discontinued FireAngel recommends the ST-622 Thermoptek smoke alarm as the most suitable replacement because it will fit on to existing S0-601 base plates. This means it can be swapped over in seconds with no drilling or obvious marks visible on the ceiling.

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 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?
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. How are smoke alarms fitted to the ceiling?
A.

Smoke alarms can be either screwed to the ceiling using the holes on the base plate (screws provided) or fixed using a sticky pad, this can be added to your basket through the ordering process.

Goes off when it should and only when it should. I bought this as a replacement for a previous incarnation of the same or similar alarm from safelinks. Very happy with it. No ridiculous squawking over slightly singed toast and other such nonsense - so when it does go off you know to take it seriously. Wouldn%u2019t be without it (them actually!)
