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.

Bought to replace obsolete model, easy to fit and regularly test so you know it'll work if it's ever needed. I had a fitting query and my call was answered by Julie. She was friendly and answered my technical query immediately. She really is a great ambassador for your company and I'd like my thanks to her noted.
