P-500: Sierra Reader
The P-500 Sierra Reader
The P-500 Sierra Reader is intended for mounting on a flat surface or a standard U.S. single
gang electrical box. It can be mounted on metal or non-metal surfaces. The P-500’s electronics
are housed in a black, weatherproof, shock resistant package. This package is mounted to the
installation surface. An attractive, snap-on, black or white front cover hides the electronics
package and installation mounting hardware providing an extra level of security.
The P-500 can be used with virtually any manufacturer’s access panel because it produces an
industry standard Wiegand output. The reader can be configured to work with access panels
using either single or dual LED control lines. It is able to read the following Keri Systems’
Wiegand cards.
• PSC-1 Standard Light Proximity Cards
• PSM-2 Multi Technology Cards
• PSK-3 Proximity Key Tags
When a card or tag is read, the P-500 immediately responds with a beep and an LED blink. The
access panel then handles subsequent LED and beeper responses. The P-500 also features
built-in diagnostics: a start-up self test to ensure reader functionality and a data line test to ensure
reader/access panel communication.

(1)
Per Wiegand specification, a minimum gauge of AWG 24 is required for data transfer in a 500-foot run length.
However the wire gauge to use should be determined by the current draw requirements of the reader, the length of
the cable run, and the voltage being 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 across the length of the run due to the resistance in
the cable). To ensure +5 VDC is available at the reader a larger gauge of wire (having less resistance) or a separate
power supply at the reader may be required.

Read Range is measured in a clean RF and electrical environment using a Keri Systems Standard Light Proximity
Card presented parallel to the reader surface. The Read Range will be less for a Key Tag and a Multi Technology
Card.

Mounting Instructions
Three holes need to be drilled to mount the P-500 Reader (see Figure 1). One large hole (7/8")
accommodates the beeper and the reader cable. Two small holes (for a #6 screw) are for
mounting the electronics package on the mullion or doorframe.

Connections
There are no switches or jumpers to set. The only configuration the P-500 requires is to set the
reader for single or dual LED control line operation (explained later in this document). The P-500
Reader can be connected to virtually any access panel that meets Wiegand interface standards.
All connections are made through the reader's cable. Please consult Table 1 and Figure 2 for
wiring instructions.
