The basic concept of the system is that there are two gate operator systems installed in tandem, a fast moving gate such as a barrier gate operator and a slower moving more secure or ornamental gate system balances the demands of speed during high traffic periods with security during low traffic periods. Barrier gate operators have the fastest opening times of many gate operator types and slide, swing or vertical pivot gates allow you to effectively seal off the perimeter of the complex that you are planning to secure This SAMS Kit system is compatible with roll up or overhead operators and can also be used with motorized traffic teeth. his is made possible as any of our Mega Series barrier gate operators monitor the full open position of the gate, roll up or overhead operator or monitor the down position of the motorized traffic teeth and raise the barrier arm once fully open. The Sequenced Access Management System or SAMS allows more control when managing vehicular entrances to areas such as apartment complexes, businesses, gated communities and parking lots. The basic concept of the system is that there are two gate operator systems installed in tandem, a fast moving gate such as a barrier gate operator and a slower moving more secure or ornamental gate system balances the demands of speed during high traffic periods with security during low traffic periods. Barrier gate operators have the fastest opening times of many gate operator types and slide, swing or vertical pivot gates allow you to effectively seal off the perimeter of the complex that you are planning to secure (Figure 1). Our Mega Series barrier gate operators have the SAMS functionality and the ability to communicate and work in tandem with a slide, swing or vertical pivot gate. Additionally, this SAMS system is compatible with roll up or overhead operators and can also be used with motorized traffic teeth. This is made possible as any of our Mega Series barrier gate operators monitor the full open position of the gate, roll up or overhead operator or monitor the down position of the motorized traffic teeth and raise the barrier arm once fully open. NOTE: Any of the Mega Series Barrier Gate Operators will work the same way. The MEGA ARM has been selected as the example for these instructions. A one second pulse from access control device to the MEGA ARM will energize its K1 relay sending an open signal to the second operator causing it to open, however, the MEGA ARM’s boom will not raise yet. When the second operator reaches its full open limit switch, this will open the COMMON and NORMALLY CLOSED contact on the EXTRA open limit switch. This will allow the original signal from your access control device (that was stored in memory) to now raise the gate arm. As long as the second operator is in the full open position, any additional open pulse sent will in turn energize the MEGA ARM’s K1 relay to send another open signal to the second operator as well as cause the arm to raise again if it has closed via a car crossing the MEGA ARM’s close loop.
