This Quick Start Guide is intended for experienced installing technicians. It is a basic reference to ensure all connections are properly made.
Models include Nortek PB-3500, PKB-2600 and PKB-3400.

1.0 Introduction

A key component of a physical security electronic access control system, a mobile-ready reader combining BLE and proximity technologies is 
based on RFID technology. In operation it is capable of reading data stored on a proximity credential via radio frequency—or reading data from 
mobile credential stored in a smartphone’s wallet app via BLE technology—and without physical contact, and then passing the data obtained to 
the physical access control system. Access control systems typically manage and record the movement of individuals through a protected area, 
such as a locked door.

2.0 Mounting Provisions

Each reader may be installed either indoors or outdoors. Mounting options shown in the table below. Use supplied #6 mounting screws, or 
equivalent security screws, for installation.

4.0 Cable Requirements

24 AWG minimum, multi-conductor stranded with an overall foil shield, for example Belden 9535 or similar, supporting the five conductors 
comprising the physical layer of the Wiegand interface (power, ground, data 0, data 1, and/or beeper and LED). Alternatively, Belden 9539 or 
similar, for all reader functions. Contact your access control system manufacturer for their specific requirements. Per the SIA’s Wiegand 
specification, maximum cable length is 500 feet (152 m).

5.0 Output Formats

Wiegand (industry standard 26-bit Wiegand and custom Wiegand formats)
Magnetic Stripe (ABA Track II, clock and data, with card present)

6.0 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.

7.0 Power

Reader may be powered by the access panel. A linear power supply is recommended for best operation.

NOTES:

a

Single Line LED:

 This is the standard operating mode and does not make use of the 

Orange conductor. The LED is Red when the reader is idle and flashes when a card is 
presented. The LED turns Green when the Brown Conductor is pulled low by the access 
control panel.

b

Dual Line LED:

 This mode makes use of both the Brown and Orange conductors. The 

Brown conductor controls the Red LED and the Orange conductor controls the Green 
LED. LED states are determined by the access control system option and capability.

Unused conductors should be trimmed, isolated and taped back to prevent unintended 
current flows. Apply positive voltage only to the Red DC Conductor.
