[Alterations to Existing System]

Hi

If adding a few extra detectors to an existing fire detection system which does not have a zone plan, is it the installer's responsibility to provide one (or update an existing one if they have one) or is it simply noted on the certificate that it is a non-conformity?

Thanks for reply AnthonyB

Not sure as yet, we've had a quick look and noticed the detectors are lsf so need to verify the sounders.

I presume if the sounders arent then its a no no?

Is there a part in the regs you can direct me to?

This has all been requested after a risk assessment, but they are no existing certs for the installation.
