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 alarms where applicable. However, if possible it is recommended that any alarms connected via interlink cable 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. 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. Do you need an electrician to connect mains powered smoke alarms?
A.
It is necessary that an electrician installs mains powered smoke alarms.
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.
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 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.
