Fitted with both optical and heat sensors to provide total fire coverage, the Ei3024 mains powered, multi-sensor alarm offers wired interlink with up to 12 compatible devices. Intelligent software allows the alarm to detect all fire types making it much more effective than a traditional single sensor alarm. Fitted with a self-charging lifetime back-up battery in the event of a mains failure, the Ei3024 contains AudioLINK technology, allowing you to extract real time data from the alarm directly to your smart phone. Also compatible with the Ei3000MRF module which allows for radio-interlinking between compatible devices.
Power: 230V mains powered with back-up battery
Backup Battery: Self-charging battery
Warranty: 5 year warranty
Suitable for living rooms, bedrooms, hallways, landings and dining rooms (not suitable for kitchens or garages)
Mains powered Ei Electronics smoke and heat alarms require a 230V AC power supply and up to 12 alarms can be hardwire interlinked in one system.
To obtain a mains power supply, each alarm can be connected to the nearest lighting circuit using 2 core and earth cable with a separate, dedicated interlink cable connecting all alarms. However, if possible it is recommended that the alarms are all powered from a dedicated circuit from the distribution board using 3 core and earth cable for safety during maintenance, as the interlink cable will carry power from live alarms on other power circuits. Please see the diagram below:-
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. Can the mains powered smoke alarm range be connected to mains power via the lighting circuit?
A.
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?
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. When the test button is pressed on an interlinking smoke alarm will this cause all the other units to go off, too?
A.
Yes, by pressing the test button on one alarm all the units in that family will also be activated. To 'teach' the units which other smoke alarms belong to the same family, the smoke alarms have to be set up together during the installation. This is done by pressing a 'housecoding button' or similar process.

Electrician who installed them said they were much better than previous ionising alarms.
Do not sound alarm when cooking which is a great improvement.

As above
All three units wired together with no problems. used 4 core but 3 would have done as no earth required. Fit of units onto bases were beautifully positive. Audio Link app was easy to use. All worked straight away. Well pleased
