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 (11)
Q. Do the three types of Ei3103 alarms interconnect with each other?
A.

Yes, the Ei3103 range, Ei3100RF - Ionisation Smoke Alarm Ei3105RF - Optical Smoke Alarm Ei3103RFU - Heat Alarm, interconnect with each other. If one sounds it will send a radio-signal to the other units and they will then be activated.

Q. Is the Ei3105RF a complete smoke alarm or does it need a base?
A.

The Ei3100RF series of battery operated smoke alarms are complete alarms, they do not require base plates to make them radio interlinked.

Q. Does the Ei3100 battery operated radio linked series have a hush button? If not how are false alarms dealt with?
A.

There are three different alarms that make up the Ei3100 series. The Ei3100 optical alarm does have a hush button, which can be pressed to reset the alarm should a false alarm occur. The ionisation and heat alarms do not have hush buttons. Should either of these alarms trigger a false alarm, due to cooking fumes for example, the alarm can be silenced using a folded newspaper to fan underneath it. To identify which alarm has triggered the false alarm it is the unit with a rapidly flashing red LED.

Q. Do the following items work together Ei407 callpoint, Ei3100 smoke and heat alarms, Ei410TRF wireless remote control switch?
A.

Yes, all the products listed are compatible. After purchase they do need to be house coded together to ensure they work correctly.

Q. Where more than one radio-interlinked battery operated smoke alarm is installed, if the battery in one alarm failed would the other alarms be affected?
A.

If one alarm was to malfunction the other units would not be affected, if it was due to alarm failure. If the fault was with the radio-interlinking signal, then all alarms that are in the chain after the faulty alarm would be affected and they would not go off.
