Requirements
Installation
Cable Requirements:
The
PRX-1
can operate at up to *500 feet (152 m) of cable, using seven-con-
ductor, 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 500-foot 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.
Output Formats:
• Wiegand (industry standard 26-bit Wiegand)
• Magnetic Stripe (ABA Track II, clock and data, with card present)
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-1
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.
FleaPowerTM Control Line:
The
PRX-1
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 Technical Practice
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. Additionally, read
range may be affected by local installation conditions. Range will be less when mounted to metal.
Note 2:
Use of a linear power supply is always recommended.
Note 3:
Minimum current draw is obtained by operating the reader in the fleaPower mode at 5 VDC
with the LED off. Peak current draw occurs when reading a card or tag.
