OVERVIEW
The Presco™ PRX Proximity Reader by Nidac is an advanced,
self contained RFID (Radio
Frequency IDentification)
contactless reader. It is capable of interfacing to either a
Wiegand input control panel or to Nidac’s new range of
Presco™ PAC decoders.
The mullion (or architrave) styling makes the PRX suitable for
door frame mounting as well as other mounting positions.
OPERATION
Connected to a Presco™ PAC decoder
The LED on the reader is red when ready to read a Presco™
prox card. When a card is presented to the front of the reader
the LED momentarily turns orange to indicate that the PRX has
read it. The code is then transmitted to the PAC decoder.
If the card is valid the PRX will respond with 1 or 2 short beeps
and the LED will change to green (provided the blue wire is
connected as shown in the wiring diagram) for the time the ELC
relay is active (door is released).
If the card is invalid the PRX will respond with a “blarp” (long
beep) and the LED will remain red.
Connected to a Wiegand controller
The LED on the reader is red when ready to read a Presco™
prox card. When a card is presented to the front of the reader
the LED momentarily turns orange and the internal buzzer gives
a short beep to indicate that the PRX has read it. The code is
then transmitted to the Wiegand controller.
The LED can be made to change colour to green by the
controller by ap5 to 15 Volts D.C. to the blue wire.
