A.R22 Vehicle ID receiver
This vehicle ID receiver will open a gate or door to vehicles carrying a valid long range radio frequency ID tag. The receiver can be connected to and powered from all known control panels. The set is supplied with two pre-programmed ID tags.
The receiver controls the gate through two relays, one for opening and another to close. Gates and barriers with auto-close function enabled will only use the OPEN relay output. A blue LED indicates a vehicle ID tag is within the zone.
Mount the receiver in a plastic waterproof housing at least 1.5m above ground for good RF reception. There is no sensitivity adjustment or any other serviceable parts inside the receiver.
To add an ID tag, power the receiver and the new ID tag. Now press the P1 button. The blue LED will light, flash twice, then stay on.
Tags cannot be cleared individually, but the whole memory can be cleared. Press the P1 button for 5 secs. The blue LED will flash 5 times to confirm, then remain out.
The simplest wiring is for gate openers and barrier panels with auto-closing. The receiver has an open relay and a close relay, both producing a momentary pulse. The CLOSE output is not normally required, but could be used to close the gate sooner than the time delay set. The wiring below shows connection to a controller with auto-close enabled.
Multi-user entrances on private car parks or gated communities may have several users entering at the same time. The control panel must have timed closing and an open input. If only a combined open and close input is available, the additional relay shown for garage door openers will be necessary.
Q. How does the system recognise the car?
It doesn't recognise the vehicle, it receives a signal from the USB tag while the tag is powered. The tag gets it's power from the vehicle USB charging socket.
--------------------------------------------------------------------------------------------------------------
Q. Can i wire the tag into the car?
Not directly, because USB device standard is 5V and vehicles are 12V (or 24V for lorries). We have an adapter to convert from vehicle power (12V or 24V) to a 5V USB socket. Most cars these days have their headlights on all the time, so wiring the adapter into the front light circuit works well. Avoid using parking light circuits which are left on.
It is best to fix the tag in a waterproof plastic container behind a plastic radiator grill, or behind a plastic bumber. Do not put it behind a steel panel, or above the engine where it could get too hot.
--------------------------------------------------------------------------------------------------------------
Q. My car USB socket remains ON even when the car is parked overnight?
Unfortunately, this USB socket is going to hold the gate open. Your options are to unplug the tag, or wire the tag into another car circuit using the 12V to USB adapter. It is possible the car has an option to power off the USB at night that needs to be enabled.
--------------------------------------------------------------------------------------------------------------
Q. Is the receiver directional?
No, the receivier is not directional. It needs to be mounted in a plastic control panel. Any steel enclosure will stop the signal and reduce range. It is often better to mount the receiver in a small plastic enclosure above the gate or fence level.
--------------------------------------------------------------------------------------------------------------
Q. Why are there two outputs?
Output 1 sends a pulse to open a gate when a tag is first detected in the area (eg driveway). In most cases, only output 1 will be used, because gates are programmed to close after a short time period. The second relay output is triggered when all active tags are out of area or switched off. This is usually for systems that don't close automatically. .

Q. Can i use this system on a garage door?
Using a Vehicle ID receiver is popular with motor bike riders who find it difficult to operate a normal remote control while wearing biker's gaulntlets. It is a luxury, especially in winter, to drive up to your garage door and have it open automatically.
Garage doors tend not to be set to automatically close. They also have simple control panels that do not have a specific close terminal. But they have a courtesy light that can be used to indicate that the door is open.
Industrial roller shutters are also a popular application for fork lift drivers or commercial vehicles. Roller shutters need to have safety photobeams fitted for the closing cycle, then the auto-close can be enabled.
--------------------------------------------------------------------------------------------------------------
Q. What happens if there are two tags within range?
The receivier keeps a note of any tag powered up and in range. Obviously, it ignores any signals from tags that are not registered to that receiver. When the tag moves out of range, or the ignition is turned off, that tag drops of the active list in the receiver. When the list nolonger has any active tags, the close output is activated. The receiver can keep a note of 300 tags at a time.
