Page 7 IMPORTANT SAFETY INSTRUCTIONS Entrapment Zones for a proper Pull-To-Open installation: Zone 1 – leading edge of the gate and the fence post. Zone 2 – between the gate and the gate post. Zone 3 – the path of the gate. Zone 4 –...
Page 8 If any of these signs or warning decals become damaged, illegible or missing, replace them immediately. Contact GTO for free replacements. The gate is automatic and could move at any time, posing a serious risk of entrapment. No one should be in contact with the gate when it is moving or stationary.
Page 9: Secondary Means Of Protection Against Entrapment Secondary Means Of Protection Against Entrapment
IMPORTANT SAFETY INSTRUCTIONS Secondary Means of Protection Against Entrapment As speciﬁed by Gate Opener Safety Standard, UL 325 (30A.1.1), automatic gate openers shall have an inherent entrapment sensing system, and shall have provisions for, or be supplied with, at least one independent secondary means to protect against entrapment.
Page 10: Required Safety Precautions For Gates
(recommended, not included) Entrapment Protection GTO’s inherent obstruction settings, even when properly adjusted, may not be sensitive enough to prevent bodily injury in some circumstances. For this reason, safety devices such as safety edge sensors (or photoelectric sensors), which stop and reverse gate direction upon sensing an obstruction, are suggested for enhanced protection against entrapment.
