Introduction
This rule demonstrates the ability to control lighting using the External Trigger actions. These actions can trigger relays if the system has been configured to use the ADAM 6060 I/O device. This configuration is based on the Area Movement Rule and combines an area check with a timer back off, which means the lights remain active for as long as a track is in the area with an additional time out if required. As soon as the track leaves the area then the timer will count down and once expired the lights will be automatically switched off.
If using the ADAM 6060 I/O device then you will need to configure and use the ADAM Plugin. The ADAM 6060 device is natively supported within Witness. The software can support more than one ADAM device therefore enabling the control of multiple external devices.
