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.
