FAQs (8)

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.

It was a replacement product for the ionising version we previously had. It seems to be a good product but still early days. It's great that they are mains powered and that they have a 10-year life.

I was pleased to be able to replace a previous ionisation version based outside the kitchen with this optical version ( again an easy straight replacement). It has already stopped the false alarms we used to get when grilling or tasting food.

good smoke alarm. It is very sensitive and it is very loud and so it does it's job. It is a bit fiddly to get the head off of the base though. This is the first time one of my old ones has gone wrong and it's 7 years old. You can't fry steak or burn toast with it if it is in the same room though, it goes on forever!!
