SAMS WIRING WITH RELAYS NOT ENERGIZED
The Sequenced Access Management System (SAMS) are programmable relays used to determine the order in which more than one control device
operates across an opening. For example, where a swing gate and a barrier gate are both used, the swing gate may be set to open all the way before
the barrier gate activates. An example of SAMS wiring is shown below.
