Installation Technician Notice
- Do not use test lights. Use digital multimeters to test all wires.
- All outputs must use relays. This is true unless connecting to a Firstech series
control module.
- All output circuits must be isolated by wiring through a standard Bosch SPDT-
style relay.
- The CompuTrack may be damaged or operate improperly if relays are not used.
- If you must invert the polarity you must use a relay - do not use a solid state
inverter.
Firstech, LLC. nor Ayantra Inc. will not assume any
responsibility for improper use and/or installation.

THEFT ALARM – Alarm trigger sense input – Alarm
sounding devices are powered by 12 volts positive. The
CompuTrack GPS unit monitors 12 volt positive and/or
negative input. When the Siren sounds for 15 or more sec-
onds it causes the CompuTrack to send an alert message
to the owner. To prevent unintended messages from being
sent, only one message is sent to the customer per event
per 24 hour day.
Violet - Negative
Alarm Sense
Yellow - Positive
Ignition Input
IGNITION – Ignition ON/OFF sense input - The YEL-
LOW wire detects a positive 12V signal when the ignition
is turned ON and a LOW signal when the engine is turned
OFF. If the option is enabled, this will allow the unit to
send an Engine ON/OFF message to the customer.
This
wire must be connected
.
Firstech, LLC. and Ayantra Inc. requires you not to install the
CT-501-PA with a fuel or ignition interrupt. Doing so may result
in damage to the vehicle and/or driver.
