Solid and easy to install with instructions if needed. Not too big and simple design. Would recommend

Adequate product but terrible installation arrangement

Leyland30 Verified Purchase

I’m sure it will operate adequately as a fire alarm but the installation arrangement is not great. The cable connection requires cable terminations and associated box above ceiling level which might be acceptable for a recess spot light but lousy for the fire alarm since you end up with a huge hole above it compromising the fire rating of the ceiling. It’s totally unnecessary, the terminations could be made in the holster that the fire alarm clips into, like a pendant. Really wouldn’t recommend. Get a 10yr battery one instead.

Easier to fit when using the seperate base

Great smoke detector, very neat, used to replace DETA smoke detectors as exact same size, would recommend easy fix bases, made installation easier and quicker, bases matched my existing with regards screw fixing holes and 20mm hole for cable entry.

Purchased two units to replace old wired and linked fire alarms , the wiring was straightforward matching the previously wired alarms .. two things to look out for is on this alarm are
1.. its power lead needs connection blocks to connect to the mains and link lead ..
2 its central connecting plug sticks out further than the base plate provided and so a hole needs to be big enough to push through the connection blocks and also clear the back of its own plug , approx about 1 inch dia centrally. There is an option to purchase an additional backing spacer which probably would allow the connections to lay flat against the ceiling ? But not sure , some reviews say it helps

Fitted to replace two 20year old ones. Electrician who fitted them said they were a simple job as the wiring was already there. Used Fire Angel base plates as it saved making bigger holes in ceiling and they don't make a big difference to the appearance.

Reasonably priced smoke alarm

Although not Toolstation's fault, this is the second replacement I've needed for a new set installed 2 years ago. They begin to malfunction and won't stop beeping. But as they're wired in, I can't just easily replace with another brand.
