electric gate operators
section 02829
operation when power is restored; battery backup shall provide complete operation of the
gate operator and all DC control devices and sensing devices, including all sensing loops, to
insure proper and expected operation of the barrier gate system in the event of a power loss;
battery charging shall be accomplished by an integral regulated battery management system
that maintains proper battery levels to insure no disruption in service in the event of line power
failure.
1. Batteries: Provide two 7-amp 12V DC batteries per gate operator for battery backup
power.
I. Control Circuit: Microprocessor electronics and solid-state control board in a weatherproof
housing; low-voltage control inputs to provide for connection of a full range of optional external
devices including safety loop detector, photocell sensors, telephone entry access systems,
access control systems, radio receivers, and a keyed manual disconnect (to provide release
and manual operation of the gate in emergency situations); provides LED indication of all input,
status, and diagnostic capabilities.
J. Additional Required Controls:
1. Internally-mounted RF receiver tuned at 315 MHz pre-wired for compatibility with
LiftMaster Security+ transmitters.
2. Inherent obstruction sensing providing separate force adjustments for both open and
closed directions, allowing a closing gate to reverse to open and an opening gate to
stop.
3. Timer-to-close providing adjustable timer settings between 0 and 120 seconds which
resets upon receiving additional open commands.
4. Bi-Part latch for dual or double gate applications requiring one leaf to open or close
before the other.
K. Equipment: Provide the following optional equipment.
1. Master/Second option providing a cable extension kit consisting of a direct burial wire,
junction box and connecting hardware to provide synchronized movement between two
gate operators in a double gate installation at a single entrance.
2. Solar panel package that allows for operation as an independent unit with the use of a
DC adapter and solar panel.
3. Antenna package including antenna, 15 ft. cable, and mounting hardware for
repositioning radio antenna.
4. Push-to-Open bracket permitting gate to swing out from the property
5. Remote controls.
