FAQs (1)

Q. How can we test the alarm to make sure it is working?

A. The manufacturer's recommendation is to test the alarm by pressing the test button. This will simulate a heat input at the heat sensor. You can also test it with a hair dryer but make sure that the hairdryer is kept away at a suitable distance from the alarm. Do not attempt to test the alarm by using open fire or excessive heat as this may damage the unit.

Very easy to install replacement for same model after 17 years Had a prolem with the first one that arrived but customer service was excellent and a replacement was shipped which fitted and worked exactly as it should. The replacement item was shipped with all the installation extras which seems a waste - it was identical to the pack advertised as being for new installation.
