Grade A ld2 system in self contained flats

[skidmark]

Hi there,

I am the freeholder of my flat. There are 2 other flats. In the building, it’s a converted terrace house.

The council have instructed me to install a grade a ld2 system. I have no idea what this means. Can anyone explain what the requirements are to appease the council?

I’m a teacher and don’t earn much money. I’m very worried about being able to carry out the works.

Many thanks

dude if you dont know dont do it cos your liable if someone dies get a proper fire alarm company in ....DONT TOUCH IT>>>>>>>
