FAQs (6)

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. I want to interlink 4 x Ei166 smoke alarms with the Ei1529RC. Do I need a spacial base (Ei128R) or is it possible to do this with the standard base the alarms come with? Also, what would we need to add the SAB300C beacon to the system?

A. The Ei160 series of detectors can hard wire interconnect with the Ei1529RC switch without the need for the Ei128R relay base. You would however require the Ei128R relay base to connect the detectors to the SAB300C beacon.

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.
