ignores, or bypasses, that sensor (along with any other sensors
sharing the same zone) for 60 minutes.
If the bypassed sensor tries to trigger the system while it is being
bypassed, the 60-minute bypass period will start over. This ensures
that a sensor that continually triggers will remain bypassed.
Doors are covered by FACT differently: If the alarm is triggered
by an open door for three full cycles, the doors will be bypassed
until the trigger ceases.
FACT is programmable. See the Programming Options section
of this guide.
note: Arming and disarming the system does not reset
this function! The only ways to reset a bypassed zone are
for it to not trigger for 60 minutes, or to turn on the igni-
tion. If testing your system, it is important to remember
that the FACT programming can cause zones to be
bypassed and appear to stop working. If five chirps are
heard when disarming, FACT has been engaged. If you
wish to clear the FACT memory, turn the ignition key on.

The microprocessor at the heart of your security system is
constantly monitoring all of the switches and sensors that are
connected to it. It detects any faulty switches and sensors and
prevents them from disabling the entire system. The micropro-
cessor will also record and report any triggers that occurred
