National Loop Co. 30' (4' X 11') Direct Burial Vehicle Detection Loop with 175' Lead-In for 15' Wide Driveways - X-NL15-14-175

The National Loop Co. 30' Direct Burial Vehicle Detection Loop with 175' Lead-In is a 14 AWG inductive loop that arrives preformed and ready to install, with its lead-in attached as part of the same continuous wire. 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. Its 11' side spans the travel lane while the 4' side runs in the direction of traffic, leaving roughly 2' of clearance on each edge, an arrangement well suited to standard 2-car driveways on modest suburban lots.

Features:

• 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
• Saves labor cost compared with winding a loop by hand in the field
• Provides the non-contact vehicle detection UL 325 gate systems count toward their two required means of entrapment protection
