The Ei160RC series of mains powered smoke alarms are fitted with a sealed rechargeable lithium long life battery. Designed to last the life of the alarm, the back up battery will not need replacing and continues to power the unit in case of a mains failure. The Ei160RC smoke alarms can be interconnected using cable, allowing all the alarms to sound if a single unit detects a fire. This interconnection feature provides occupants with the earliest warning in case of an emergency.
Ionisation and optical smoke alarms Kitemarked to BS EN 14604:2005
The Ei160 series of smoke and heat alarms require a 230V AC mains power supply. Up to 12 alarms can be hard wire interconnected on one circuit.
To obtain a mains feed, the first alarm can be connected to the nearest lighting circuit using 2 core and earth cable. From this alarm, 3 core and earth cable is required for all additional alarms, which allows for the hard wire interconnection to work. Please see the diagram below:-
Alternatively, the alarms can be hard wired using a dedicated circuit from the distribution board.
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?
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?
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?
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?
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?
Yes, the bases for the Ei140 and Ei160 series are identical units and are interchangeable.
