New Delta Loop Detectors Help Negate Unexpected Gate/Barrier Openings/Closings
FOR IMMEDIATE RELEASE
VALENCIA, CALIF. – June 15, 2000 – Recommending its use with all Delta and most other vehicle access control systems, Delta Scientific’s NP Series Digital Loop Detectors are programmed to prevent a closing signal when power is resumed. NP Series Loop Detectors are directly interchangeable with most other brands as a plug-in replacement.
“These loop detectors provide customers with a safety detector that can prevent accidents which occur when power outages cause vehicle access control systems to reset their logic,” affirms David Dickinson, senior vice president of Delta Scientific. “The 3446 NP Series incorporates an advanced micro-controller that combines a powerful digital computer and the latest and most advanced inductive vehicle loop technology to give high-test reliability and accuracy when measuring, counting or detecting vehicles.”
This ability helps avoid unexpected gate operations such as the raising or lowering of gate arms, sliding gate operation, motorized teeth and barricade actuation. According to Dickinson, Delta highly suggests and is seeing a wider application of vehicle loop detectors to suppress the operation of heavy gates and vehicle barricades to prevent accidental closings or raisings when authorized vehicles move through vehicle access control systems.
Typical digital loop detectors hold a gate open until the last part of a vehicle has passed the closing loop, located beyond the gate. The detector then gives a pulse on departure, instructing the gate to close after the vehicle has passed. Oftentimes, after power outages, the entire system needs to be reset. The NP Series negates this problem.
Delta NP Series Loop Detectors provide input voltages of 24 VAC, 24 VDC, 120 VAC and 230 VAC.
