SAFETY RECOMMENDATIONS

Automatic gate operators can produce high levels of force, therefore it is very important that all gate operator system installers and
designers are fully aware of potential hazards that exist with an incorrectly installed or designed system. The internal safety capabilities
of a gate operator system are not enough to reduce the risk of injury. The operator is only one part of a properly installed system,
which when combined with correctly installed safety devices will yield a complete system that will not only provide convenience and
security, but will be safer with a minimal risk of injury.
The following information along with the check list (and the rest of the manual) is provided to make you aware of potential areas that
are of a safety concern. Disregarding any of the following may result in serious injury or death.
INSTALL THE GATE OPERATOR ONLY WHEN THE FOLLOWING HAS BEEN ADDRESSED:
• Two warning signs securely installed on each side of gate panel (required).
• 1 or 2 safety photo beams installed, one across each side of gate opening (required).
• 1 or 2 stop photo beams installed on each side of fixed gate panel (back area).
• Photo beams installed according to their instructions and in areas that pose entrapment risk.
• Customer advised that gate in for vehicular traffic only (required).
• A separate pedestrian entry and/or exit is provided (required).
• Contact edges installed and functional at all hazard or pinch points.
• Safety guards installed covering all cantilever wheels (required).
• All controls located far out of reach of gate, fixed panel and operator (required).
• This class operator is approved for the application of the operator (1, 2, 3 or 4) (required).
• A sphere with a 2-1/4" diameter cannot be pushed through the gate or fixed panel.
• A safety screen/mesh is installed with a minimum height of 4' from ground.
• Controls intended to reset gate after obstructed installed in line of sight (required).
• Hard wired contact sensors located and wired to avoid any mechanical damage.
• Customer instructed and is clear on proper use of gate operator (required).
• Customer instructed on proper use of all control devices used with operator.
• Safety instructions were reviewed and left with customer (required).
• Installer offered a preventative service/maintenance contract.
• A photo of completed installation taken from front and back of gate and dated.
• Advised customer that for manual operation they must disconnect batteries and AC power.
• If installing this unit on a gate that allows a 2-1/4" sphere to pass through it, the gate must be corrected before the unit is put
into operation.
• Gate must be installed in a location so that enough clearance is supplied between the gate and adjacent structures when opening
and closing to reduce the risk of entrapment (required).
Do not disconnect the siren in any way. Switch S1#6 must stay on and S1#8 must stay off. Tampering with the siren or switch
settings may pose the risk of serious injury or death. (NOTE: Does not apply to versions 6.30 or higher. These switches were
redefined for new functions. The siren cannot be disabled by changing these switches on 6.30 or higher.)
