Customer Reviews

  • from Kent Rating:5 stars

    Absolutely fantastic help with replacing our 15 year detectors...got exact up to date replacement...fitted all three in fifteen minutes

  • from Derry Rating:5 stars

    Website was easy to navigate to find direct replacements for my discontinued fire alarm. Delivery times were excellent. I had to rewire the connector but this was an easy process. Would definitely recommend safefiredirect.

  • from Harlow Rating:5 stars

    Good replacement for firex 1240c. I choose this one as it has a 10year internal rechargeable battery. No need to worry about changing it every year. I did have to rewire the new plug on to the existing terminals but there is only 3 connections so if you can wire up a plug you can wire one of these up.
