The SimpleAccess SR3 Mobile Access Card Reader Overview
The SR3 is a 125kHz Prox and Bluetooth Low Energy (BLE) all-in-one commercial reader for access control systems. The reader can retrofit legacy PACS systems using proximity, otherwise known as prox to easily implement an enhanced user experience at the door. The reader is both cost-effective and easy to install, without requiring any rewiring or paneling.
The SR3 is intended to be used in conjunction with an access controller as part of the access control system to provide secure access to buildings or areas. The reader is installed and communicates an access request to the controller using the standard Weigand protocol. This request is made by the end-user presenting either prox card or fobs using ASK or FSK modulated Wiegand formats; the user can also use a Bluetooth-enabled device storing mobile credentials powered by UniKey mobile application.
Introduction
This guide will walk a professional installer through the steps needed to attach a SimpleAccess SR3 to an access control panel. The SR3 supports 125 kHz proxy access cards as well as mobile credentials. Please review the information below to ensure the reader is installed quickly and properly.
Grounding
- The shield must run continuously from the reader to the panel. At the panel, the reader ground, shield line, and earth ground must be connected together at a single point.
- Do not ground the shield line at the reader end as this will create a potential ground loop.
Power
- Please be aware that when searching for the power source or controller, this may not be readily accessible depending on which building or door you are installing the SR3 reader. We recommend contacting your building tenant or owner for access to the power source or controller to ensure proper installation. If access to the controller is not possible, do not proceed with removing the previous reader.
- It is recommended to find the datasheet for the currently installed reader to better understand the current reader to ensure proper connection for SR3.
- A non-switching power supply at the panel is recommended to power the reader for the highest noise immunity and best performance.
- For UL 294 Compliance, the readers shall be connected to a class two power-limited power supply or control panel output.
- The minimum wire gauge is 24 AWG with a maximum length of 500ft (150m).
Note: Performance will likely be unreliable if these standards are not met.
Voltage
- The minimum reader voltage required is +6 VDC to a maximum of +16.0 VDC, and 12.0 VDC is recommended.
- The reader will require 100 mA (typical @ 12 VDC)
Connection
- Connections must be in accordance with NFPA 70. DO NOT connect to a receptacle controlled by a switch.
Mounting the Reader
- Prior to installation, a voltage meter is recommended to check the input voltage of the reader. Connect the meter to the power and ground lines to verify that at least 6 volts is supplied by the controller.
- DO NOT remove an existing reader before matching up the function/purpose of each wire (regardless of wire color) so that in the event that the wires do not match, functionality is still clear.
- If the unit is used to control a door or pedestrian gate, locate the unit as near as practical to the entry point. If the unit is mounted on or in a wall adjacent to the entry point, be sure the wall is sturdy. The repeated shock and vibration from a slamming access door or spring-loaded pedestrian gate must be isolated from the unit.
- Never mount the reader directly on a moving door or gate.
- Choose a well-lit location near the controlled opening. Wiring access for power, network, and earth ground must be available to the mounting location.
- Both the Mullion and Single-gang readers can be mounted on a wall or any suitable flat surface.
Mounting Instructions
Note: Ensure the power supply is not energized until all wires are properly connected and terminated.
- Identify and mark the location on wall for mounting screws approximately 3 inches apart. Before drilling, confirm that the power supply wires are in the center.
- Drill two holes and install wall anchors to support mounting screws.
- Feed power cable through mounting bracket’s center opening.
- Place mounting bracket on the wall, aligning screw mounting positions with wall anchors and inserting screws.
- Connect reader wires to corresponding Wiegand wiring on panel.
- Connect the power supply wires to the reader and feed excess cable back into the wall.
- Mount reader into upper and lower mounting points.

Additional Troubleshooting
Reader Behavior |
Root Cause |
The reader is flashing orange and/or flashing white and beeping repeatedly |
· Enough voltage is present but not enough current. Apply additional power from the controller or external power supply. Check the condition of the wiring. |
Reader boots but does not beep after presenting prox card |
· The prox card may not be a supported format, or the reader is likely getting >5V but <6V |
Power is present, but no response occurs when a card is presented |
· Recommended voltage for the SR3 is 12V, but 6-16V is supported. Verify that the voltage between the red and black wires is greater than 6V under all conditions. |
Reader beeps after presenting mobile credential but doesn’t open the door |
· The card number may not be enrolled in the controller database. Verify the card number that was issued to the mobile credential. · If the reader did not flash green, check that the white and green wires are connected correctly. |
Power is 12V and reader beeps when a card is presented but door does not open |
· The green and white Wiegand lines might be not connected to the controller or are connected backward, or the reader may not be Weigand at all (this should be verified). · The cable may be longer than 500ft |
Power is 12V and door opens when a card/mobile credential is presented but reader does not display green animation |
· LED line (Blue wire) from the controller may not be connected to the reader. · If it is connected, try disconnecting the blue wire and touching it to the black wire while the reader is powered up. Does the line turn green? If so that means the reader hardware is functioning properly. · Check the configuration on the controller, it may be in a mode that operates the Blue line differently than is expected. For the Green LED to operate correctly, the Blue line needs to be pulled down to 0V when access is granted. |
The reader is not getting any power at all |
· The wires may have not been connected properly. The installer needs to verify that each wire is coming from the SR3 reader and coming from the controller. · The power from the controller is not sufficient. Please use a voltage meter to verify a minimum voltage of +6 VDC coming from the controller. This is the minimum proper power rating for the reader. |
SR3 Animations
Each animation corresponds with a specific response from the SR3 and can be customized individually for the user’s commercial organization. Other animation colors as well as various presentation styles are just some of the alternatives available for the UniKey SR3.
SR3 Reset
A reset is performed in order to clear the reader of existing organizations and corresponding end-user credentials. Access to any specified organization will need to be re-established before continuing reader use.
- To locate the reset button on the reader, dismount from the installation points. The reset button is located on the back of the reader, as depicted in Figure 1.
- Confirm that the reader is still connected to power source; The LED ring should display a solid blue animation.
- Hold down the reset button for a minimum of 5 seconds.
- After the reader has successfully completed the reset, the LED ring will momentarily flash a series of red, white, and amber blinking. Once the amber is solid, the reset is complete.
- The reader’s enrollment has now been cleared and is ready to be enrolled at a specified organization.
