Default Alarm system transformer + power supply (would both go bad atonce?)

Tony, I worked in the alarm industry years ago and to reset and alarm
board may not be as simple as shorting a jumper. This prevents another
company from hijacking your customer accounts. It's a security feature
and the reset is a code in static ram that may only be possible to
access by first putting in the installer's code. It really depends on
how easy or difficult the manufacturer has made it. ^_^


I visited a few intrusion alarm shops today and the Bosch definitely
has a LOCK code (that's what they called it) on the board.

That super-secret lock code allows *only* them to program the circuit
board.

The owner of the home is never provided that lock code, I was told.

Incredulously, I asked why, and they said it prevents burglaries.


You could probably purchase a DSC board and keypad to install in your
existing can, reusing the same wiring, switches and detectors. I think
there are several places on the web including eBay where you might get
one. I purchased a number of main boards only to install inside
generator transfer switches to monitor the generators. DSC makes pretty
good stuff. ^_^
