The Ei600RF series of battery powered smoke and heat alarms are ideal for properties where the installation of mains powered alarms would cause unnecessary mess and disruption. The built-in RadioLINK+ modules allow wireless connection between all the linked alarms in your property including many other Aico and Ei Electronics products, helping to ensure all building occupants are are given the earliest possible warning of a potential fire.
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. What is the difference between an ionisation and an optical (photoelectrical) smoke alarm?
Ionisation smoke alarms detect fast flaming fires and are suitable for landings. Optical smoke alarms detect slow smouldering fires typical for burning soft furnishings. Optical alarms are suitable for living rooms and sleeping areas and are used near kitchens as they are less prone to false alarms. Please note that ionisation alarms contain a small amount of radioactivity.
Q. Would the Ei600 series be suitable for installation in flats? The system needs to be grade A or grade D.
The Ei600 series does not conform to grades A & D, it conforms to grade F, relating to battery operated interlinking smoke detection. Both grade A and grade D systems relate to mains powered interlinking alarm systems. The alarms that would be suitable for your application are the Ei140 series and the Kidde Firex.
Q. Do the Ei600 series alarms need 230v or do they just use battery?
The Ei600 series of radio-interlinked alarms are completely battery operated. This means that they do not need to be wired up to the mains circuit. On the website, we offer the Ei600 series with a standard 9v battery or with a 10 year lithium longlife battery. The standard 9V batteries last approximately 12-18 months depending on how often the detectors are tested. The lithium battery units are sealed and last 10 years i.e. the full lifespan of the detector.
Q. Where more than one radio-interlinked battery operated smoke alarm is installed, if the battery in one alarm failed would the other alarms be affected?
If one alarm was to malfunction the other units would not be affected, if it was due to alarm failure. If the fault was with the radio-interlinking signal, then all alarms that are in the chain after the faulty alarm would be affected and they would not go off.
Q. Do I need to take out all the batteries in my radio-interlinked alarms before adding a new alarm into the system?
No, you do not need to remove all the batteries. Just simply press the house code button on all the units. Please ensure that the batteries have full power as this could render the house code process incomplete.
