Trigger Mode Selection Jumper

The trigger mode selection jumper allows you to select between single and

repeatable triggers. The affect of this jumper setting is to determine when the time

delay begins.



SINGLE TRIGGER – The time delay begins immediately when motion is first detected.



REPEATABLE TRIGGER – Each detected motion resets the time delay. Thus the

time delay begins with the last motion detected.

Imagine that you want to control lighting on a dance floor based upon where the

dancers are dancing. Understanding how the time delay and trigger mode interact

will be necessary to controlling that lighting in the manner that you want.
