Product Overview

The Ei3100RF series of smoke and heat alarms are battery operated and have a built-in radio-interlink facility. Requiring no wiring whatsoever, up to 12 alarms can be interlinked to form a single system and the interlink is achieved wirelessly by radio signal. When one alarm sounds, it sends a signal to all other interlinked alarms and sounds those too. This radio-interlinked feature provides occupants with the earliest possible warning of fire.

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 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. Please see the diagram below:-

FAQs (15)
Q. Can every type of Ei3100 series RF smoke alarm be used as a repeater (a smoke alarm that not only picks up other RF signals but also re-sends it to strengthen the signal and increase the reach of the system)?
A.

Each type of Ei3100RF smoke alarm can be set as a repeater. However, only one repeater per smoke alarm system is allowed.

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

This recommendation has been superseded by BS 14604:2005.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. Do the Ei3100RF alarms require anything other than fixing to the ceiling to install them?
A.

No, with this series of radio interlinked alarms there is nothing other than pressing the house code button required to install them.

Q. If the radio interlinking signal on one unit fails will the units still work as stand alone units.
A.

Yes, should the radio interlinking signal fail the units will continue to sound independently should they detect a fire.

Q. Can a wireless router interfere with the radio interlinked alarms?
A.

A wireless router is very unlikely to interfere with the signal of your radio interlinked alarms, as the RF signal of the smoke alarms is digitally coded.

Very easy to set up. I was fitting 9 units around my house and initially reading the instructions for coding and setting up a repeater unit made it look daunting. In fact it was very easy, only took a couple of minutes and all alarms linked perfectly.
