electric gate operators
section 02829
K. Additional Required Controls:
1. Internally-mounted RF receiver tuned at 315 MHz for use with LiftMaster DIP switch,
billion code, and Security+ remote controls.
2. Inherent obstruction sensing providing a slight reverse/full stop if an object is contacted
while opening or a complete reopen if an object is contacted while closing.
3. Entrapment sensor to temporarily shut off motor for 3 seconds upon contacting an
obstruction which causes the operator to labor, followed by a slight reverse of direction
away from the obstruction before shutting off the motor again resulting in a full stop of
the gate.
4. Soft start/stop capabilities providing extended gate system life.
5. Timer-to-close providing adjustable timer settings between 0 and 60 seconds.
6. On-board 3-push button control for close, stop, and open of gate.
7. Two-stage surge/lightning protection protecting against a lightning strike within a 50-ft
radius.
8. Emergency release to manually operate the gate.
9. Dual gate operation capabilities to allow two separate gate operators to operate in
unison at a single entrance.
10. Internal alarm to activate whenever the gate encounters an obstruction.
11. Master/Second capability to provide synchronized movement between two gate
operators in a double gate installation at a single entrance.
L. Non-scissor swing aluminum arm designed to be free of pinch points and to bend when at
the break point if the gate encounters an obstruction.
M. Equipment: Provide the following optional equipment.
1. Battery Backup: An externally mounted battery backup system to automatically engage
in the event of a power loss and auto-reset to normal operation when power is restored;
battery backup shall provide complete operation of not only the gate operator, but all
control and sensing devices, including all sensing loops, to ensure proper and expected
operation of the barrier gate system in the event of a power loss; battery charging shall
be accomplished by a regulated battery management system that maintains proper
battery levels to insure no disruption in service in the event of line power failure.
2. Heater to keep gearbox at optimum temperature range.
3. Integrated, plug-in loop detector modules to create safety and exit loops.
