The Company I Work For Has Just Been Given A Service Contract On This Panel But If I Can Remember Right This Is A Very Old Addressable Panel Which Only Has Basic Functions Like Silence Then You Get A Pen And Press It Through The Hole To Reset. Is There Any Hidden Features In The Main Board To Put This In A One Man Walk Test Or To Disable Sounders. It Has A Switch To Turn Off Remote Signal And That Is It (on The Front Of Panel).
Best of British , they are only addressable , a right pig of a panel , I don't remember any OMT on these , the small reset button is to do with the power up reset if you log any more devices onto the system. It works adding the next available unused number , once spent 2 days on a fault as it wont log on pass the detector , which in my case was 004 that was causing problems , how many jobs have you been on that are actually addressed how it was wired ?
Any new style detectors will require a new blown eprom , i think it was called a poo chip.( Says it all really)
I would advise your customer to allow in their budget some contingency's for upgrade.
Note : Don't be surprised if you see devices in the panel , power supply etc , obviously if equipment was removed the panel eprom would still see it , and nobody's going to readdress the whole system.
