contact is closed. Now, a contact will be made to the limit switch input at the terminal board through both limit switch contacts. Both motors will be turned off.

A wiring schematic of the Bi-Parting installation is shown in Figure 15, page 14. It is important this schematic be followed closely and that the color codes at the MECHANICAL UNITS and the CONTROL BOX be followed exactly. Most of the difficulties encountered with Bi-Parting installations are due to the wiring instructions not being followed.

ACCESSORY EQUIPMENT HOOK-UP

All accessory equipment is connected to the 18 terminal barrier strip located inside the GS4000 Control Box. To expose this terminal strip, remove the cover on the Control Box.

There are 13 command inputs (#3 through #15) available to the installer on the GS4000 in a addition to a common terminal (#16). To trigger any of these inputs, a switch or relay closure to the common terminal for a duration longer than 100 milliseconds and of a resistance of less than 100 ohms is necessary. Eight of the inputs, FREE EXIT (#5), OPEN (#6), STOP (#8), REV LOOP (#11),

BI-PARTING WIRING

For a Bi-Parting installation, an additional two conduits must be installed between the First Mechanical Unit and the Second Mechanical Unit. (See Figure 8, page 8.) For a Bi-Parting installation, one operator must be a Left Hand unit and the other a Right Hand unit.

The two motors of the Bi-Parting GS4000's will be wired in parallel. BOTH motors will run until both are shut off. If the two gate leafs do not open exactly the same amount, then the first gate leaf to reach it's open position will have to be held (or mechanically stopped) in that position until the second gate reaches its open position. Now, both motors can be turned off. The stop for the first gate can be installed externally or the GS4000 internal Stop Pall mounted on the large output drive sprocket of the GS4000 may be used.

The Limit Switch contacts of the two Bi-Parting units need to be wired in series. Both limit switch contacts must be closed before a connection is made to the limit switch input at the Control Box to stop the motors at the Open or Closed position.

The operation of the Bi-Parting installation is as follows: After receipt of a command to open, both units will begin to open together. The first gate to reach its open position will be stopped by the mechanical

stop. Its motor will continue to run. The Torque Limiter will be

 

adjusted to slip when the stop is encountered with the motor still

 

running. The limit switch contact on this first unit is adjusted to

 

close at this position. The second gate has not reached its fully

 

open position. Its limit switch will be still open and no command

 

will be given to the limit switch input at the terminal board until the

gate has reached the maximum open position and the open limit

ANSI/UL 325 specifications

Allstar Products Group is a prominent manufacturer in the realm of access control and safety products, and its commitment to quality is evidenced by its compliance with ANSI/UL 325 standards. These standards are essential for ensuring the safety and reliability of automatic gates and their related components, focusing on minimizing risks associated with entrapment and injury.

One of the key features of Allstar's ANSI/UL 325 compliant products is their advanced safety mechanisms. These include integrated sensing technology that detects the presence of objects or obstacles in the path of the gate, effectively preventing accidents. This safety technology often encompasses features such as photo eyes and edge sensors that can immediately halt or reverse the movement of a gate if an obstruction is detected.

Additionally, Allstar’s product range is notable for its robust design and durability. Built to withstand various environmental conditions, these products use high-quality materials that ensure longevity and reliability, meeting the stringent demands of both residential and commercial applications. The designs are also forward-thinking, incorporating user-friendly features that allow for easy installation and maintenance.

Another characteristic that sets Allstar apart is their integration of advanced technologies. Many of their products support smart technology, enabling users to control their gates through mobile applications or remote access systems. This integration allows for convenience and enhanced security, providing real-time alerts and status updates.

Allstar Products Group also emphasizes compliance to facilitate peace of mind for users. All their ANSI/UL 325 certified products undergo rigorous testing procedures to ensure they meet the stringent safety and performance requirements set forth by the American National Standards Institute and Underwriters Laboratories. This adherence to such standards not only assures consumers of reliability but also aligns with the industry’s best practices.

In conclusion, Allstar Products Group’s ANSI/UL 325 compliant products exemplify cutting-edge safety features, robust construction, and advanced technology integration. Their commitment to quality and safety ensures that customers can enjoy the benefits of automatic gate systems with confidence, knowing that they adhere to the highest safety standards in the industry.
