The Ei3018 is a mains powered carbon monoxide alarm with built in, rechargeable lithium back-up battery to be used in the event of a mains power outage. This alarm is fitted with a high performance electrochemical sensor, designed to sense the presence of carbon monoxide. The sensor is individually calibrated and tested in CO gas to ensure accuracy. The Ei3018 also has AudioLINK technology like other alarms in the Ei3000 series meaning that you can extract real time data from the alarm via a smart phone. The alarm can be hard-wired with up to 12 other compatible devices or for radio interlinking, the Ei3000MRF module can be purchased separately and placed in the rear of the alarm.
Please Note: The Ei3000MRF SmartLINK module for radio-interlinking is sold separately.

Good quality is more convenient than having a battery type, and because it can be used with a relay to turn off the boiler when activated, it is the best for safety.

I purchased this item to replace an old one that has reached the end of its life. Unfortunately, the base plate has changed and I needed to fit a new base plate. The screw holes are in a different place on the new one to the old and unfortunately, the placement of them meant that I had to move the base plate, exposing the screw hole to the original base plate. It would be good if manufacturers took the placement of the screw holes in to account when updating a product.
