C. UL Classification:
1. Conforms to Class I, when tested in accordance with UL325.
2. Conforms to Class II, when tested in accordance with UL325.
3. Conforms to Class III, when tested in accordance with UL325.
4. Conforms to Class IV, when tested in accordance with UL325.
D. Operator Enclosure: Powder-coated, weatherproof, locking, 14 gauge galvanized steel cabinet
over a metal frame.
E. Operator Motor:
1. GC Model: 1 HP Continuous Duty motor with built-in overload protection.
a. 115 VAC 60 Hz Single Phase operation.
b. 208 VAC 60 Hz Single Phase operation.
c. 230 VAC 60 Hz Single Phase operation.
2. GI Model: 2 HP Continuous Duty motor with built-in overload protection.
a. 208 VAC 60 Hz Three Phase operation.
b. 230 VAC 60 Hz Three Phase operation.
c. 460 VAC 60 Hz Three Phase operation.
d. 575 VAC 60 Hz Three Phase operation.
F. Open and Close Limit Settings: NEMA 4 limit switches that are modular and fully adjustable.
G. Control Circuit: LiftMaster Model GL solid-state digital logic control board including low-
voltage control, external spike and surge protection, separate open and close external sensor
inputs, fully adjustable inherent obstruction detection system, dual gate operation, built-in radio
receiver, and optional external devices including loop detectors and telephone entry systems.
H. Additional Required Controls:
1. Internally-mounted RF receiver tuned at 315 MHz.
2. Inherent obstruction sensing providing separate, single force adjustments for both open
and closed directions, allowing a closing gate to reverse to the opposite limit and stop
when encountering an obstruction.
3. External obstruction sensing providing separate open and close cycle input connections
for external contact and non-contact sensors.
4. Maglock control relay to activate and deactivate an optional magnetic lock for securing
the gate.
5. UL 325-compliant entrapment warning alarm system providing ability to offer a warning
tone which begins 3-seconds prior to gate movement and continues during gate
operation.
6. Loop detector inputs allowing for the connection of exit, shadow, and interrupt loop
detectors.
7. Control wiring distance can exceed 1,000 feet (305 meters) to allow exibility of gate
operator placement.
