*Any* UL or ULC listed station would act on a tamper alarm. No matter how
"brief".

Most panels have a "pager" notification option. Talk to your alarmco to
confirm it's available and activate it. I can tell you that your CS *will*
act on a tamper signal.

The chances are extremely slim that anyone would be "lucky enough" to cut
the wire in this manner. He'd have to have to be sitting on a bag of
horseshoes.
