FAQs (9)

Q. For mains powered Aico smoke and heat alarms, when the electricity supply fails and the back up battery takes over, please can you tell me how long the battery will last in this situation?

A. For mains powered Aico alarms with a new, fully charged lithium back up battery, the battery would last approx. 3-6 months without a mains supply. For mains powered Aico alarms with a standard alkaline back up battery, the battery would last up to a year without mains supply. If the alarm has been installed with an Ei168RC radio frequency base, please note that the Ei168RC back up battery would last approx 2 months if the power fails.

Q. My detector does not have "RC" stated at the end of the code. What does this stand for?

A. The RC just refers to "Remote Control" as the unit can be fitted to a radio-frequency base for interconnection. The model hasn't changed but the manufacturers changed the product code slightly in reference to this.

Q. Can I upgrade an existing Ei140 series base with a Ei160 series smoke alarm?

A. Yes, the bases for the Ei140 and Ei160 series are identical units and are interchangeable.

Q. How do you wire in the Ei140/Ei160 series of smoke alarms?

A. To wire the units correctly you would use 2 core and earth cable to the first unit and 3 core and earth to the interconnected units. The alarms do not have to be earthed but a brass screw connector is provided so that the earth can be safety terminated.

Q. Can I link a CO detector with a Ei140 smoke alarm?

A. Yes, we recommend the Ei261EN. You should also install a Ei159 locator to allow you to find out if the alarm was triggered by CO gas or by fire.

Product first class and electronic reminder to test it is an excellent idea. I found installation of the smoke alarms to be easy and they operate very well. The idea to then arrange for emails to be sent on a regular basis is genius and should ensure automatic safety within the home. Overall an excellent product!

excellent product and excellent service can't really add much apart from the fact that your website was easy to use and the delivery of the alarms was rapid and without problems. Have recommended your website to all 5 of my neighbours in my close. I live on a housing estate where most if not all the alarms now need replacing and the alarms are most probably the same as mine therefore for a consideration I'd be quite willing to advertise for you.

Very straightforward installation. Delivered on time. I purchased these to replace an older version - which I had managed to pull the battery connector off. (Didn't realise you have to replace the regularly anyway). Replaced both upstairs & downstairs interlinked units. Absolute doddle, and look much better than the old units.
