Wiring Explained

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:-

FAQs (10)

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. Does this alarm conform to BS 5446 part 1 as recommended by the Fire Service?

A. This recommendation has been superseded by BS 14604:2005. All of our smoke and heat alarms conform to this standard in accordance with the Kitemark.

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.

Thhe linking is useful in our large house. Installation was very easy. Tricky to remove to change the battery despite the tiny print instructions on the side a more prominent release lever and a guide on the size of screwdriver would have helped.
