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 (7)
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.

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 upgrade an existing Ei140 series base with an Ei3000 series alarm?
A.

Yes, the new Ei3000 series is fully backward compatible and will work directly with the the Ei140 series base. Both the power supply and the interlink with any remaining Ei140 alarms will continue to work with your new Ei3000 alarm.

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

BS 5446-1:2000 was withdrawn in 2008 and replaced by BS EN 14604:2005 to conform with European standards. All of our alarms containing a smoke detector (smoke only, smoke & heat, smoke & CO) are fully compliant with BS EN 14604:2005. They also comply with any other relevant standards relating to their other detection capabilities.

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. What sort of smoke alarm system would I need to install for a HMO?
A.

BS 5839-6 recommends that one or two storey HMOs with an individual floor area of no more than 200sqm (not the total of both floors) should have a Grade D smoke alarm system installed. Grade D refers to mains powered smoke alarms with a back up battery power supply. The alarms can be interlinked either by wire or by radio signal and the system does not require a separate fire alarm panel. For HMOs of 3 storey or higher, a Grade A panel system would need to be installed. This can cover the whole of the building, or can be used just for the communal areas with a separate Grade D system installed for the individual dwellings. For both applications, the level of cover should be a minimum of LD3 (in all escape routes) but this may change according to the fire risk assessment.

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.

Worked well when tested. It should have a 10 year battery as standard. How much more is it going to cost with it? Better have it installed and charge a few Pounds more. The electrician fitted mine and handed me the 10 year batteries saying %u201Cyou have some spare batteries%u201D
