This special accessory is an adjustable timer with a built-in 15A relay. The ‘pulse’ timer can be triggered by a +
or - pulse, or a change of state (from + to -, or visa-versa) on the stripe wire.
NNoottee::
Do not exceed 15 amp draw with the 528T or damage will occur. If more current is needed,
use the timer with an external 30 amp SPDT relay.
This product has many popular uses by installers of mobile electronics. Some examples include: creating a wait-
to-start trigger for remote starting diesel vehicles that do not have wait to start triggers.
If you need to disconnect a circuit for a certain amount of time so that the alarm does not activate, you can
use the pulse timer’s normally closed circuit. Pulse the strip wire to disconnect the circuit for up to 60-seconds.
