INSTALLATION To prevent SERIOUS INJURY or DEATH from a moving gate: l ALL gate operator systems REQUIRE two independent entrapment protection systems for each entrapment zone. l Entrapment protection devices MUST be installed to protect anyone who may come near a moving gate. l Locate entrapment protection devices to protect in BOTH the open and close gate cycles. l Locate entrapment protection devices to protect between moving gate and RIGID objects, such as posts, walls, pillars, columns, or operator itself. Step 4 Install Entrapment Protection Entrapment protection MUST be installed according to the following UL 325 requirements: l Slide gate operators require a minimum of two external monitored entrapment protection devices to function; one in the open direction and one in the close direction. l Every installation is unique. It is the responsibility of the installer to ensure that ALL entrapment zones are protected with an external monitored entrapment protection device, protecting both the open and close gate cycles. l LiftMaster monitored external entrapment protection devices MUST be used with LiftMaster operators to meet UL325 requirements, see Accessories. l Test ALL entrapment protection devices after completing installation of the operator. For testing instructions, refer to the manual provided with your entrapment protection device.
