What type of fire alarm system should I install?
The guy above is right, a lot of clarification is needed here. If I try to answer your question as broadly as it is asked, then here is my answer.
First, if you already have any security systems, I highly recommend purchasing a fire alarm from the same company. For example, I have monitoring and alarm systems from Ajax, so I also purchased a fire alarm from https://ajax.systems/.
Secondly, there are sensors that respond to different markers – directly to fire, to smoke, to carbon monoxide. Here you need to sit down and think about what is more suitable.
And thirdly, it’s better to take a wireless, battery-powered one, I think everything is clear.
