Fire Alarm And CO Alarm Test That I Do Once A 3 Months

This is me showing you and testing the fire alarms and CO alarms that I have got in my house, I show you the different makes, the series their from (e.g. like the Aico Ei141 is from the Ei140 series) and models (but of course there are some with an unknown model) and I test the sounders and sensors to make sure they are working, this is something I do once a 3 months. But there are some alarms that are hard to test (e.g. the Aico mains heat alarm is hard to have it's sensor tested with a hair dryer and the Aico mains smoke alarms are hard to test with smoke spray so then I have to use real smoke from a match, but of course please do not do this because it can be dangerous!), so I had been struggling and having delays testing them and have been choking from the smoke spray. Also there are some that still had testing spray in their sensing chamber, so then I ended up having to take the battery out until I thought that the chamber had cleared. But anyways guys, please don't forget to leave a like, subscribe to my channel or leave a comment box down below and click on the notification bell if you want to be notified when I upload more videos.
