What is loop detection?
Loop detection is an always-on feature of your switch that helps you identify and remove loops on your network.
When your network has a loop, the switch is connected to itself and network traffic is looping and growing continuously instead of reaching its destination and stopping..
How does a boom barrier work?
A boom barrier, also known as a boom gate, is a bar, or pole pivoted to allow the boom to block vehicular or pedestrian access through a controlled point. Typically the tip of a boom gate rises in a vertical arc to a near vertical position. Boom gates are often counterweighted, so the pole is easily tipped.
What is a loop detector on Gates?
Vehicle Loops and Loop Detectors are used to detect the presence of a vehicle to open a gate, or as a safety device to prevent the gate from closing on a vehicle in its path. Inductance Loops are available as Direct Burial or Cut-In.
What is barrier gate system?
Boom gate or barrier gate systems use a bar to block vehicle traffic. Typically the tip of the barrier arm rises to allow entry or exit access. From airports to office buildings,and parking ramps barrier gates efficiently manage vehicle traffic.
What is an exit loop?
Exit Loops automatically open the gate when a vehicle drives over them, they also will hold a gate open and reverse a closing gate which means they can used in place of an inside reverse loop. A reverse loop will reverse a closing gate if a vehicle is detected.
How do you test a loop detector?
To check leakage disconnect loop from detector. Use a multi meter to measure the resistance from one loop wire to ground (stick long nail in dirt if operator does not have ground). Be sure that other loop wire is floating (not connected). If there is less than 10 Meg Ohm leakage to ground, loop is faulted.
How does a loop detector work?
Inductive loops work like a metal detector as they measure the change in the field when objects pass over them. … Once a vehicle drives over a loop sensor the loop field changes which allows the detection device to detect the presence of an object (mainly a vehicle).
What is a vehicle detection loop?
Vehicle detection loops, called inductive-loop traffic detectors, can detect vehicles passing or arriving at a certain point, for instance approaching a traffic light or in motorway traffic. An insulated, electrically conducting loop is installed in the pavement.
What is a hearing loop and how does it work?
A hearing loop (sometimes called an audio induction loop) is a special type of sound system for use by people with hearing aids. The hearing loop provides a magnetic, wireless signal that is picked up by the hearing aid when it is set to ‘T’ (Telecoil) setting.
