A great product but even better was the service from Safelincs who also absorbed the delivery costs and offered further installation advice if I needed it. This is the second time I have bought all my fire alarm systems from them and would definitely recommend them to anyone else.

I have linked heat and smoke alarms - the smoke alarm died and I puchased this one as a replacement however it will not link to the heat alarm I already have. They look identical but for a silly red spot on the back - very disappointed that this wasn't made obvious at ime of purchase!
