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 alarms where applicable. However, if possible it is recommended that any alarms connected via interlink cable 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.

Weight 0.45kg Product DatasheetsQ. How can we test the alarm to make sure it is working?A.
The manufacturer's recommendation is to test the alarm by pressing the test button. This will simulate a heat input at the heat sensor. You can also test it with a hair dryer but make sure that the hairdryer is kept away at a suitable distance from the alarm. Do not attempt to test the alarm by using open fire or excessive heat as this may damage the unit.Q. Is it possible to have a heat alarm mains powered radio interlinking alarm interconnect with battery powered radio-interlinked alarms?A.
Yes this entirely possible. The Ei140 series with RF base is mains powered and these are compatible to interlink with the battery operated Ei3100 series. Please view the interconnection overview on either of these alarms for further details.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. I have added an Ei168RC164RC wireless linked heat detector to my garage some time after the installation of various other wireless Ei160 detectors in the house. What do I have to do to get the system to recognise the new detector please?A.
To get the Ei168RC164RC to communicate with the existing alarms, you would need to housecode all the units again. Press the housecode button on the new Ei168RC base and on each of the existing units.Q. Please could you explain how the repeater function works on the Aico/Ei radio interlinked detectors.A.Show All
Hello. The radioLINK repeater function allows the smoke alarm to "repeat" the radio frequency signal around obstructions. This stops the signal from becoming blocked and ensures that all interlinked alarms can be reached. This repeater function is built-in to the the Ei168RC radioLINK base (with Ei140, Ei160 or Ei2110 alarm), the Ei600 series of radio interlinked battery powered smoke and heat alarms as well as the Ei262 and Ei208WRF carbon monoxide alarms as standard. When house coded, the system works itself out which alarms are to act as repeaters - it's not something you set up yourself.
