A friend's burglar alarm needs testing, probably several times.
I know it would be better if I had the model number for the wireless communicator to her monitoring service, but she's not living there now and it will be weeks before I go there again.
"In general" if one unplugs the wire from the alarm box to the cellular communicator**, does the system work again as soon as it's plugged back in, or is some setup needed. I don't have the procedure for setting up the communicator.
If not "in general" then, the case of the alarm you have.
**(so that the testing doesn't require calling the alarm company in advance each day)
Her alarm is old, Moose Z1100E, but the communicator is about 4 years old.
