TROUBLESHOOTING
I TRIGGERED THE ALARM SIREN FOR A VERY LONG TIME BUT THE PAGER
ONLY UPDATED ME TWICE.
This is normal. In most cases the pager will not report more than 2 no-
tifications per session. But if there is a long enough delay between trig-
gers
(e.g., between multiple shock sensor triggers), then the pager should
notify you each time the trigger occurs.
WHEN I PRESS THE TRUNK BUTTON THE FULL SIREN BLAST OCCURS.
A long press on the Trunk button produces a Trunk Release output, while
a short press should only update the Pager with the car’s current sta-
tus. If the siren blasts, then you need to Disarm and check the Status
LED flashes. Page 9 of the 1480 or 1460 Owner’s Guide shows what
each flash pattern means. Seven (7) flashes show the Shock Sensor (or
another attached sensor) is the culprit. The most likely cause of a shock
sensor trigger in that case is your installation. If shock sensor’s wire har-
ness touches or is in close vicinity to the Paging System’s “Antenna Unit”
wires, false triggers can and will occur, and they may not even be related
to your pressing the Trunk button. The fix is simple. Just use wire ties to
keep the shock harness as far as possible from the Antenna Unit harness.
Never allow the two harnesses to touch.
THE FULL SIREN BLAST OCCURS MOST OFTEN IN STRONG SUNLIGHT.
Never put the Antenna Unit in direct sunlight. That normally causes
communication problems with the pager, but other problems can occur as
well. We also received one report where mounting the Shock Sensor in
strong sunlight caused it to trigger. While this is rare, in such a case, we
recommend relocating the sensor to see if that helps, but make sure the
sensor is never located near sources of strong RF signals, and make abso-
lutely sure the shock harness does not touch the Antenna Unit harness.
YOU SAY NOT TO MOUNT THE SHOCK SENSOR TO METAL. WHY NOT?
The car’s metal frame is the most sensitive part. You normally may not
see any problem, but if you park close to another car and if they slam
their door rather hard, that shock wave is sent throughout the body of
your car, and if the shock sensor is affixed to metal it will detect that door
slam. In such cases the Warning Chirps would likely trigger, but the
full siren blast could occur if you set the sensitivity high. If you affix the
sensor to metal, a bus or Harley Davidson motorcycle or muffler-modified
sports car driving by could cause a trigger. Low frequency shock waves
are filtered-out only when you affix the shock sensor to firm plastic sur-
faces in your car. You can affix it to metal, but false triggers may occur.
