OVERVIEW
The Presco™ Sprite Proximity Reader 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 range of Presco™ PAC decoders.
The full potting makes it suitable for outdoor environments and
the narrow styling makes the Sprite 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 Sprite has
read it. The code is then transmitted to the PAC decoder.
If the card is valid the Sprite 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 Sprite 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 Sprite 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.
