National Loop Co. 56' (6' X 22') Direct Burial Vehicle Detection Loop with 20' Lead-In for 28' Wide Driveways - K-NL28-14-20

Built for sites where saw-cutting is not an option, the National Loop Co. 56' Direct Burial Vehicle Detection Loop with 20' Lead-In is a preformed 14 AWG loop encased in liquid-tight conduit. Wired to compatible automated system, the loop counts as one of the two means of entrapment protection UL 325 requires for gate operators, detecting the metal of any vehicle over the sensing area so the gate stops or reverses before contact. Crews place the loop on the prepared sub-base before paving, and the new asphalt, concrete, or gravel surface locks it in place. With the 22' side crossing the lane and about 3' of clearance per edge, and the 6' side capturing vehicles in the direction of travel, the layout fits apartment complex entrances and farm or agricultural property gates.

Features:

• More cost-effective than hand-wound loop installations
• Fills the non-contact detection role UL 325 assigns to vehicle loops in a 2-device entrapment protection system
• Designed for vehicle detection with gate operators, parking barrier gates, overhead doors, traffic signals, arming devices, and vehicle counters
• Wound from one continuous, non-spliced wire, leaving no splice point between the loop and lead-in to fail
• Heavy-duty, liquid-tight conduit shields the loop from sharp stones, chemicals, ground heaving, and harsh weather
• Fully assembled at the factory, so there is nothing to wind, count, or connect before paving
• Predetermined number of turns removes the guesswork of achieving optimal read range
