Excellent device with a very audible alarm. You will not sleep through this! I received very helpful advice about the type and siting of the two alarms. One for the lounge / diner and one for the upstairs landing. My previous alarms from the 1970's (still working but yellow cases) were bell wire inter-connectable and these two product work together which is what I was looking for.

Incorrect ones came but no probs with refund. Thank you. I ordered what I thought were hard-wired alarms and when they came, they were only battery operated. I called the company and spoke to the Ops manager who was more than happy for me to refund the money including the postage that I paid, which was credited back to me really quickly. One thing, I think maybe the wording is a tad ambigious for a novice like me and could be stated more clearly that they are battery operated only. Thank you.

5 stars for construction looks and performance. Sturdily built and looks very good in place. Passed all tests. The back plate of the unit has one hole for the interconnection wire and not a lot of room for drilling another so I wasn't able to replace my units without filling twelve screw holes and repainting six patches on my ceilings. There is a label which has to be pierced in order to slip the wires for interconnection through. The label very easily rips, don't rely upon it to keep out any dust or debris from a hole in a plaster ceiling that your wire pokes through.
