T530 Question

Hi,

Yes - the dreaded Minerva T530 extinguishant panel 

As there seems to be a lack of information on this panel anywhere on the net (!), wondering if someone with a manual could just confirm for me if this panel has the facility for a "hold-off" to be fitted. I seem to remember that it does, but as I've seen that many panels over last couple of weeks, I can not be 100% and just want to confirm.

Teach me for not taking pictures of terminals..........

Thanks in advance
