GATE INSTALLATIONS
• It is recommended that you attach fine mesh or
screening across the inside of swinging or sliding
gates in order to prevent intruders from reaching
through the bars and releasing the trolley from the
door arm or pressing the door control button.
• The opener must be protected from rain and/or
moisture.

SWINGING GATE INSTALLATION
Safety Reversing Sensor
(Optional Accessory)
Without a properly working safety reversal system,
persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing gate.
• Activate gate ONLY when the gate is in full view and
free from any obstructions.
• ALWAYS keep gate in sight until completely closed.
NEVER permit anyone to cross the path of the moving
gate.
• ALWAYS keep gate in good repair and make sure it
moves freely. An improperly maintained gate may NOT
reverse when required and could result in SEVERE
PERSONAL INJURY or DEATH.
