SAMS DEFINITION
The Sequenced Access Management System or SAMS allows the customer more control when managing vehicular entrances to areas
such as apartment complexes, businesses and gated communities. The basic concept of the system is that traffic is controlled by two
gates installed in tandem, a fast moving gate such as a barrier gate operator and a slower moving more secure or ornamental gate
such as a single or pair of slide/swing gate operator. The design of this gate system balances the demands of speed during high traffic
periods with security during low traffic periods. Barrier gates typically have the fastest open times of the many gate operator types and
the slide or swing gates allow you to effectively seal off the perimeter of the complex you are planning to secure.
NOTE: Connect all entry devices to the slide or swing gate. If using a device, such as a 7-day timer, to latch the slide or swing gate
open during high traffic times, connect the device's N/O relay output to the GL board's Interrupt Loop input. Once the device activates
the Interrupt Loop input, the next vehicle to access the SAM system will lock the gate in the open position until the device deactivates.
When the device deactivates, the timer to close will automatically close and secure the gate.
SAMS OPERATION
1) When an authorized vehicle accesses the gate system, the
SAM system responds by first opening the gate farthest from
the vehicle, the swing or slide gate.
2) Once the swing or slide gate is open, the barrier gate begins
its open cycle.
3) Once the barrier is open the vehicle may pass through the
SAM system. At this point you have two options in how you
would like to initiate the SAM systems closure. You may chose
to:
a) Use a timer to close system to automatically close the
barrier gate after a preset amount of time or
b) Use a loop system to close the barrier gate after the vehicle
has passed through the SAM system.
4) Once the barrier gate is closed the slide or swing gate will
activate its internal timer to close and begin closing.
5) If another authorized vehicle accesses the SAM system before
the slide or swing begins to close the barrier will open and
allow the vehicle to pass through the SAM system.
6) If another authorized vehicle accesses the SAM system during
the slide or swing gates closing cycle the SAM system will
reopen the slide or swing gate. Once the slide or swing gate
reaches the open position the barrier will then open to allow
the vehicle to pass through the SAM system.
7) If no other authorized vehicles access the SAM system the
swing or slide gate will close followed by the barrier.

SAMS WIRING
1) Install conduit between the BG770 and the SL540/570 for
SAMS control wiring.
2) Run a 4-conductor cable in the conduit between the BG770
SL540/570.
3) Locate the SAMS relay terminals (J5) on the GL board in the
SL540/570 and locate the auxiliary limit switch in the BG770.
4) Attach a wire from the SAMS relay terminal (J5) on the GL
board to terminal 1 on the BG770 terminal strip.
5) Attach a wire from the SAMS relay terminal (J5) on the GL
board to terminal 3 on the BG770 barrier gates terminal strip.
6) Attach a wire from terminal 5 of the terminal block to the
common (COM) on the auxiliary limit switch in the barrier
gate.
7) Attach a wire from terminal 8 of the terminal block to the
normally open (NO) on the auxiliary limit switch.
8) Test for correct functionality of the SAM system.
