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.

FAQs (6)
Q. What type of electrical cable is required to carry the mains supply and trigger signal for the wired alarms?
A.

For the mains supply of the first unit a 2-core earth cable would be sufficient. For the connection between the alarms a 3-core earth cable would be required

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. 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.
