    Fire Sentry Micro Smoke Alarm

    I found my Kidde smoke alarm easy to order from you and I was impressed with the speed that I got my delivery and also notification by e-mail re the actual delivery date. The product is nice and compact and easy to install and I have had one before. If I need anything else for my house regarding any domestic type of appliance, then I would certainly use e-spares again. I thought the 2 smoke alarms were also good value for money. I have your e-spares magnet card as a reminder on my fridge!

our old alarms have come to an end, they were stuck on to ceiling, no problem, put there by fire-service many years ago. Can these alarms be put up the same way.

    The alarm comes with fitting instructions, we believe these are attached by a mounting bracket that has to be screwed into the wall or ceiling.
