When first powered up its in a test mode showing open circuits. Once you clear them all it will then go to rest / day mode.
One option is to remove all circuit wiring (marking up first and take a photo) then link out all to prove the panel. If the panel functions with all circuits, tampers etc closed then you have a base point to start from
on power up from new (if you reset it then its the same sort of thing) it will show active circuits till you press a button etc. Whats concerning me is the fact its not accepting the default code. If its that old it wont have an engineer code. Just the user code.
It is knocking on though an optima compact gen4 isnt exactly much.
Old yes useless maybe not, worth spending much time on, no. But depends how much you need it and how important reliability is. Is also god a horrid cheap battery on it that certainly wont help if it was ever 2.2Ah id be astounded
agreed but 2000 ohms is a lot. I would expect it to be the pir but if you test the tamper switch at 200 ohms this will confirm, testing set on 200k wont show a high reading. It should be very close to 0.3 ohms (not 0.3 K Ohms) plus whatever size the built in series resistor ir (not the ones in the terminals) you could try adding something to the red dot to adjust the close point if the case is slightly twisted
Put your meter on 200 ohms.
Yes short the blue and yellow to check the cable but I'd expect a connection or the tamper switch the reading should be steady and not fluctuate
Disconnect the circuit at the panel and meter the tamper pair on the sensor. The tamper switch is the red dot.
Then short the cables at the pir and measure the resistance at the panel
As above if an intruder alarm fails to perform your insurance company would claim from the maintaner. Thats why Insurance companies want an approved company as they have to have the specialist insurance for this. As such systems are locked down to prevent an innocent change to the config actually having unforseen problems. So without that you may not have a valid insurance cover
agreed looks like a big blustu, maybe an isdn one?
also looks more like outputs in use apart from pin 1. Is it on a Fire panel?
However just a heads up not sure it ever passed CE
