electric gate operators
section 02829
6. Heater: Chamberlain / LiftMaster MA201 Thermostat Control Heater; designed to
automatically maintain a suitable temperature inside a control enclosure for temperatures
below 32 degrees F (0 degrees C).
7. Pedestals: PED42 Pedestal; 42 inches (1067 mm) high; mounts to pre-existing concrete
pad; 11 gauge steel construction; power coated black; 2 inch x 2 inch (51 mm x 51 mm)
square post; faceplate with universal hole pattern. Includes hardware.
8. Pedestals: PED4272 Dual height Pedestal; 42 and 72 inches high; mounts to pre-
existing concrete pad; 11 gauge steel construction; power coated black; 2 inch x 2 inch
(51 mm x 51 mm) square post; faceplate with universal hole pattern. Includes hardware.
9. Emergency: Chamberlain / LiftMaster ACP17 Fire Access Box.
B. Chassis: Manufactured from 1/4 inch (6 mm) rustproof T-6 aluminum alloy for superior heat and
corrosion resistance; powder-coated.
C. Operator Enclosure: High density polyethylene plastic.
D. Operator Motor: 1/2 HP continuous duty 24VDC operator that provides for up to 6000
operating cycles per day; left- or right-hand operation.
E. Battery Backup: Barrier gate housing shall contain an integral and internally-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 DC control devices and sensing devices, including all sensing loops,
to maintain normal operation of the barrier gate system in the event of a power loss; gate(s)
open on power failure with a 15 second delay; 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 12V DC batteries per gate operator for battery backup power.
F. Gear Reduction: Heavy-duty 10:1 gear reducer in synthetic oil bath.
G. Control Circuit: Microprocessor (RISC) electronics and solid-state control board; low-voltage
control inputs provide for connection of optional external devices including loop detectors,
telephone entry systems, access control systems, and radio receivers.
H. Additional Required Controls:
1. Internally-mounted 312 HM radio receiver.
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. Soft start/stop capabilities providing extended gate system life.
4. Dynamic electronic braking to provide gate position control and ensure consistent gate
closing without coasting.
5. Dual gate operation capabilities to allow two separate gate operators to operate in
unison at a single entrance.
6. Automatic Closing Timer: Timer-to-close providing adjustable timer settings between 1
and 33 seconds.
