I've been asked to look at a panel (presumed for now to be M-Series). It's five years old and has started generating alerts for panel battery low. I can fit a new battery but am reluctant to take the panel lid off as I don't know if I'll need eng code to reset tamper.
It was a new build house and a contractor installed alarms in all the properties. There was no maintenance contract as far as I know. The default eng code (1234) has no effect (assuming you just enter the code from normal unset state) so presume installer changed it. Lots of questions here so any help from professionals is welcome. Q1: Is it incumbent on the installer to tell the owner the eng code on request; i.e. does the eng code belong to the owner? Q2: If installer says the eng code is some sort of master that they use for other alarms, can the owner insist that the installer revert the code to default 1234? (at no cost to owner for site visit). Q3: Am I right in suspecting that by default, a tamper will need eng reset? Q4: If so and I don't have the eng code, what's the consequence; e.g. is the system useless until reset? Q5: If I tried a factory reset and find the NVM is locked, are the two options (a) get the original installer to reset (with call-out cost) or (b) send panel to Menvier (with repair cost)? Q6: If Factory Reset did work, I know I'd have to sort out zones/wards/attributes, etc. I've got a list of zones from the user menus: 8 are straight off the panel. Two more are off the RKP (1011 PAB near front door, 1012 switch on front door). There's also a PAB in the bedroom, zone 2011 - how's that likely to be connected? Could there be a LEC2 expansion module and if so, where is it? (inside the main box?). Zone resistances are around 2.2k so I presume it's set up with FSL using 4K7/2K2 resistors.
