false alarm control technology (FACT II)
Your system offers FACT II, a feature that prevents annoying
repetitive trigger sequences due to a faulty sensor or environmental
conditions such as thunder, jackhammers, airport noise, etc.
Here’s how it works: The alarm triggers three times. If the same sensor is
triggering the alarm and the first and the third triggers are within 60 min-
utes of each other, FACT
II
will interpret this pattern of triggers as false
alarms. After the third trigger, FACT
II 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
II
differently; if the alarm is triggered by an
open door for three full cycles, the doors will be bypassed until the trig-
ger ceases. FACT
II is programmable. See the Programming Options
section of this guide.
nnoottee::
Arming and disarming the system does not reset this function! The
only way to reset a bypassed zone is for 60 minutes or to turn on the igni-
tion. If testing your system, it is important to remember that the FACT II pro-
gramming can cause zones to be bypassed and appear to stop working.
If you wish to clear the FACT II memory, turn the ignition key on.
