STARTER DEFEAT NORMALLY CLOSED
STARTER DEFEAT RELAY WIRING DIAGRAMS
STARTER DEFEAT NORMALLY OPEN
The Starter Defeat/Anti-Grind relay socket can be wired in either normally closed or normally
open configuration. In either configuration, the Starter Defeat relay also provides Anti-Grind
protection during remote start control, to prevent accidentally grinding the starter if attempting
to start the vehicle using the key. The main unit default setting is normally closed operation.
In normally closed configuration (default), the starter is only disabled when the alarm is powered
up and in the armed state. In the event power to the alarm module is disconnected, the vehicle
will be able to start using the key, even if the alarm had been armed prior to power loss. The
normally closed configuration is considered a fail-safe because the vehicle will still start if the
alarm loses power (blown fuse, etc.). This is the recommended installation method.
The normally open configuration provides a higher level of security by only allowing the vehicle
to start if the system powered up and is in the disarmed state. If power to the system is lost
for any reason, even while disarmed, the vehicle will be unable to start. The normally open
configuration provides the highest level of security but without fail-safe. If the normally open
configuration is selected, Programmable Alarm Feature step 10 must be set to button 2.
