Troubleshooting: Alarm

Shock sensor doesn't trigger the alarm:

•

Was the onboard shock sensor adjusted before the brain was mounted? If so re-adjust the sensor.

•

Has the onboard shock sensor been turned down all the way? If so re-adjust the sensor

•

Has the NPC® system been triggered? If so, you hear 5 chirps when disarming. To check this,

turn the ignition key on and off to clear the NPC® memory, and then retest the shock sensor. For a

detailed description of NPC®, see Nuisance Prevention Circuitry section of this guide.

Door input does not immediately trigger full alarm. Instead, sounds are heard for the first 3 seconds:

•

That's how the progressive two-stage door input works! This is a feature of this system even if the

door is instantly closed again, the progression from pretrigger sounds to full trigger sounds contin-

ues.

Closing the door triggers the system, but opening the door does not:

•

Have you correctly identified the type of door switch system? This happens often when the wrong

door input has been used.

System does not passively arm until it is remotely armed and then disarmed:

•

Is passive arming programmed ON?

•

Are the door inputs connected? Is the blue or gray wire connected to the door trigger wire in the

vehicle?

•

Either the green or the violet should be used instead.

Door input does not respond with the progressive trigger, but with immediate full alarm:

•

Does the Status LED indicate that the trigger was caused by the shock sensor? (See Table of Zones

section of this guide.) The shock sensor, if set to extreme sensitivity, may be detecting the door un-

latching before the door switch sends its signal. Reducing the sensitivity can solve this problem.

Door locks operate backwards.

•

This unit has easily-reversed lock/unlock outputs. Recheck wire connections to see if you have

reversed these.
