Hi Guys
Ive been working in fire alarms for 7 years now both carrying out design, install and comissioning of systems both installed by ourselves and some installed by electricians.
ive come across install's carried out by electricians and some have been good, others have been quite terrible that have cost the customer's more money to put right, i know that not all sparkies are cowboys but i should emphasis that as stated above if you install a fire detection system that should be compliant to BS5839 then you need to make sure all the avenue's are covered.
As members of organisations such as BAFE,NSI etc we have to meet certain standards of install,comissioning and maintenance otherwise we are liable for prosecution should the system fail to operate and someone is seriously injured or even killed.
If your unsure of what you are doing then the simple thing is dont do it, the consequences could be severe
