Viking PRX-2, PRX-5 Product Manual
PRODUCT MANUAL
Designed, Manufactured and Supported in the USA
COMMUNICATION & SECURITY SOLUTIONS
Features
The model PRX-2 is designed to be mounted directly to
standard single-gang wall box, and integrates both a
125KHz proximity card reader and keypad into a singleunit making it ideal for applications requiring an access
credential and/or personal identification number (PIN).
The proximity card reader and keypad of the PRX-2 are
both capable of transmitting data in 26-Bit Wiegand
format, making it compatible with any of the Wiegand
equipped Viking entry controllers. The keypad is based
upon cutting-edge, non-mechanical, capacitive
technology, which, unlike membrane keypads, includes no
moving parts prone to early failure. Advanced keypad
enhancements include fully potted circuit board (EWP),
keys with blue LED backlighting, raised key outlines and
pip on the 5-key.
The PRX-2 delivers non-contact read ranges up to 6
inches (152 mm), and operates from 5 to 14 VDC.
Mounting is simplified with horizontal and vertical
mounting slots, which allow the reader to be conveniently
adjusted and leveled. Concealing the mounting hardware,
the PRX-2 ships with both Black and Ash (Off-White)
covers standard.

Requirements
Wiring
Installation
Cable Requirements: The PRX-1 can operate at up to *500 ft (244 m) of cable, using seven-conductor, shielded, stranded cable. Per the
Security Industry Association’s Wiegand specification, AWG 24 (such as Belden 9537) is the minimum gauge required for data transfer in a 500foot run length. However, the proper wire gauge to use must be determined by the current draw requirements of the reader, the length of the
cable run, and the voltage applied to the reader.
If the reader is to be operated at 5 VDC, 5 VDC must be available at the reader (long cable runs have a voltage drop due to the resistance in
the cable). A larger gauge of wire (having less resistance) or a separate power supply near the reader may be required to ensure 5 VDC is
available at the reader.
Grounding: Shield (drain) continuity must run from the reader to the access panel. Shield (drain) and reader ground must be tied together at
the access panel and connect to an earth ground at one point.
Power: The PRX-2 may be powered by the access panel. As such, the reader is powered on when the access panel is powered on. However
the best case is to power the reader by a separate, linear power supply.
Voltage: 5 to 14 VDC Note: For maximum read range, a minimum of 12VDC is recommended.
FleaPower
TM
Control Line: The PRX-2 can be placed in a special lower power mode by pulling the purple colored fleaPower Control Line low.
This special low power mode reduces the average power required by the reader.
* Note: When used with a Viking Entry System/Controller, see the Entry System’s Product Manual for the maximum wire run length.
Note 1: Read range is stated in a clean RF and electrical environment using Viking proximity cards presented parallel to the reader surface
with the reader operating at 12 VDC. Read range may be affected by local installation conditions. Range will be less when mounting to metal.
Note 2: For user orientation in non-illuminated environments the 5-key is always illuminated.
Note: If powering the reader from
its own power supply, the negative
lead of the power supply must be
connected to the BLACK lead on
both the reader and the controller.

IMPORTANT: Electronic devices are
susceptible to lightning and power station
electrical surges from both the AC outlet
and the telephone line. It is recommended
that a surge protector be installed to protect
against such surges.
