This Quick Start Guide is intended for experienced installing technicians. It is a basic reference to ensure all connections are properly made. Models include ACSR35L, ACSR62L, and ACSR64L long-range readers.
Introduction
A key component of a physical security electronic access control system, a mobile-ready reader combining BLE and contactless smart card technologies is based on RFID technology. In operation it is capable of reading data stored on a contactless smartcard credential via high 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.
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.


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.
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.
Read Mode: In regards to contactless smart card credentials, the reader will only read and output the credential’s Card Serial Number (CSN) when the Violet conductor is pulled low (connected to ground). Otherwise, the reader will only read and output the credential’s programmed Sector data.
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).
Output Formats
Wiegand (industry standard 26-bit Wiegand and custom Wiegand formats)
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
Reader may be powered by the access panel. A linear power supply is recommended for best operation.
Voltage
8 to 14 VDC. 12 VDC at the reader is recommended for best operation.
Read mode
For sector data reads, do not connect the Violet conductor (leave it high). For CSN reads, pull the Violet conductor low (connect the Violet conductor to ground).
Connection
Connection must be done in accordance with NFPA 70. Do not connect to a receptacle controlled by a switch. Connect to a power limited DC voltage source.
Troubleshooting
- When the reader is first powered on it will beep 4-times, and the LED will shine red.
- Presenting a supported access credential will result in the reader beeping and the LED flashing once.
- Mobile operation is optimized for smartphones supporting Bluetooth LE version 4.2. Further, for the downloading of mobile access credentials, a stable, high-quality internet connection is recommended.
If the reader does not recognize the mobile credential or card or tag (no beep, no LED flash) or exhibits short read range, please see the table below for possible causes and solutions.

Should any of the corrective actions mentioned above not improve performance, disconnect the reader from the access panel and power it with a separate power supply or 9VDC battery, and re-test card functionality. By powering the readers separately, most variables that may lead to reduced performance can be eliminated. Should the problem persist, please contact Speco Technologies directly.
