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 (3)

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.

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. Are there any restrictions to the distance a radio-interlinked smoke alarm will work?

A. Most radio-interlinked alarms have a range of 150 meters in an open space and up to 30 meters in buildings. The thickness of the walls and partitions will affect the travel distance of the signal.

These radio smoke alarms are easy to set up, 30 seconds for all 3 bought, and are loud when activated. I recommend this product especially where there are some in difficult positions for testing regularly. In such cases it is unlikely that they will get a test!!
