- What's Included
With the EMX BG-VK2 BlueGuard VK2 Bluetooth Free Entry Wireless Access Control Module you can have wireless control over an array of systems with Bluetooth-enabled smartphones. This can include gates, doors, lighting and other devices that use low voltage relay control. What makes the EMX BlueGuard VK2 so innovative is its versatility—it combines wireless Bluetooth technology with a wired low-voltage relay system. So rather than carrying your keyfob around, or an RFID card, the EMX BlueGuard VK2 can provide access control from Bluetooth-enabled smartphones. With a range of up to 33 feet, you can conveniently open gates and doors without having to strain yourself. Say goodbye to reaching through car windows; just pick up your Android phone, open the app, and enter your pin.
The BlueGuard VK2 can be used to create any number of wireless applications: automatically having lights turn on when you get home, remote gate access, arming and disarming security systems, triggering electronic door strikes and more.
As long as you are in Bluetooth wireless range of the BlueGuard VK2, you can conveniently open gates and doors by entering a unique PIN or activating a one-touch BlueGuard app calibrated for Android smartphones. Using the one-touch interface, the app will send a signal to the BlueGuard VK2 creating a contact closure and triggering the built-in low-voltage relay. That relay then sends a signal output to the device you want to have controlled; ie. access control via an electronic door strike. To ensure that your property stays secure, BlueGuard VK2 pairs with Bluetooth-enabled devices using a unique 6-digit PIN created upon initial set-up. If you want to grant friends, family, employees, tutors, and/or other guests remote access using BlueGuard VK2, it can be programmed to recognize an unlimited number of devices with the PIN. If you are installing this module outdoors, ensure it is not exposed to direct moisture. Additionally, BlueGuard VK2 can be used in industrial locations for warehouse and office security and access control.
BlueGuard and INSTEON
Automatically power on your garage and porch light using the BlueGuard VK2. Maximize the potential of this Bluetooth module by integrating it with your INSTEON home automation system. Wiring the BlueGuard VK2 with an INSTEON I/O Linc will give you the convenient ability to simultaneously activate other INSTEON devices (such as an INSTEON bulb as shown below) through your INSTEON Hub, or other INSTEON dual-band device*.
* INSTEON Communication:
INSTEON I/O Linc sends and receives signals via powerline, it does not have RF capability. For I/O Linc to communicate with another INSTEON device (as suggested in the above example), the receiver or Hub must be on the same electrical phase, unless another Dual-Band INSTEON device is already in place on same electrical circuit as the I/O Linc.
When it comes to installation, the EMX BG-VK2 requires some basic wiring knowledge and may require the help of a licensed electrician. The BlueGuard VK2 should be installed in the wall as a permanent fixture. Trace the rear enclosure for a cutout template, slide into the opening, adjust the braces, and install the faceplate. Wiring will be dependent on the application as shown above. An adjustable time can be set to a simple 3 second pulse for relay trigger, or up to a 90 second pulse to eliminate a need for a supplemental timer. The BlueGuard VK2 can be installed outdoors but cannot be in an area exposed to moisture like rain.
The included 4-foot cable provides connections to the wiring box for power, output, and control signals. BlueGuard VK2’s output consists of a set of form C contacts. The BlueGuard module can be wired to control Normally Closed, Normally Open, and Common relay installations. The VK2 triggers your contact closure with a 5-second pulse. The ARM input provides a means to prevent the BlueGuard from activating its output when it's not needed. This feature may be useful when used with a vehicle loop detector, allowing the BlueGuard to activate its output only when a vehicle is present. When the ARM input is connected to the ARM common the BlueGuard is disabled. Leave this connection disconnected if not used. The common contact is common to both the normally open (NO) and normally closed (NC) contact. The NO contact will close when an authorized phone comes into range while the NC contact will open.
BlueGuard’s user interface features a secure, magnetically activated switch to place the unit in set-up mode. See below for more detailed installation instructions:
1. Connect a digital voltmeter or buzzer to the brown and green wires to check continuity, a DVM should measure “open.”
2. Connect the BlueGuard module to power 5A @ 240VAC (attach the red + and black – wires)
3. The Blue LED will be ON for about ten seconds
4. Place the magnet against the BlueGuard housing and continue to hold it there. The blue LED will turn on for 10 seconds followed by a medium flashing for an additional 20 seconds. Remove the magnet during the medium flashing and the LED will flash faster for 3 minutes. During the 3-minute period BlueGuard is in “Discovery Mode” and can connect to Bluetooth-enabled devices
5. The BlueGuard module can be activated by any Bluetooth-enabled smartphone by entering a unique pin or with Android smartphones using a one-touch app interface.
6. To configure the BlueGuard app, press the blue icon button and start the set-up process by selecting the grey set-up button. Enter your device’s name and PIN.

The BlueGuard VK2 can be used to create any number of Bluetooth controlled relay applications: automatically having lights turn on when you get home, remote gate access, arming and disarming security systems, triggering electronic door strikes and more. BlueGuard VK2 specifically notates that it should not be used with garage door systems. Each model in the BlueGuard family is structured for a specific installation. The BlueGuard VK2 is a Bluetooth PIN or app based low voltage trigger that installs in-wall for permanent application in drywall.
