How does a Fire Damper Work?

In this video we show how a fire damper works. It's a fusible link that when heated, breaks and releases a spring-loaded shutter. In this case it's set to 72 degrees with an alloy fuse.
You can see that even with the relatively low heat of a standard heat gun, the fusible link breaks and the spring of the shutter slams it closed. If you'd like to read about a Fire Damper in detail, then here's an article about them bit.ly/fire-damper
If you need your fire dampers testing and you are in the North West of the UK, then speak to kimpton.co.uk

So that's what that thing was that was preventing the office from getting heat! (the linkage failed) Had a lot of fun figuring that one out!
