The ECKey EK3 Bluetooth-enabled Professional Relay Unit offers all of the same features as the ECKey EK2 with several advanced features. Like the ECKey EK2 Virtual Keypad, the ECKey EK3 Professional Relay allows you to use a Bluetooth-Enabled phone or PDA as a key to lock and unlock almost any electronically controlled access control device such as a door lock, gate, alarm or garage door. The ECKey EK3 is a Bluetooth based electronic relay unit that installs next to your electronic lock. By leaving your phone's Bluetooth setting in Discovery mode, the EK3 will detect your phone when you walk into range (which is adjustable from three feet to 30 feet). The advantage to using the EK3 (instead of the EK2) is that you can create hands free access for up to twenty users, with no PIN required, so it will work for the whole family. The EK3 relay will automatically trigger when the corresponding Bluetooth device is in range. Once your phone is registered its presence will automatically unlock the door, open the gate or disable your alarm. You don't even need to take your phone out of your pocket. The option of requiring a PIN confirmation for preregister phones is also available, as well as dynamic range tuning options. Both the ECKey and your phone can be hidden from everyone else with 128bit encryption of billions of rolling codes as used for internet encryption. It works with any Bluetooth device without any software installation on the phone. Using the MK3 Management Kit software, the EK3 can be configured to have PIN once, PIN every time, change the relay between pulsing and toggle, change the PIN and manage the registered phones. The PC software can communicate with the EK3 via the included Bluetooth dongle or USB cable. What's Included # ECKey EK3 Bluetooth-enabled Professional Relay Unit # Owner's Manual The ECKey EK3 Bluetooth-enabled Professional Relay Unit does NOT come with a power supply. The power is drawn from the same source as the electric door strike/gate or mag lock, each sold separately, that it is being used for. Please refer to the sample wiring diagram. Applications # You drive up and your Bluetooth car kit talks to ECKey which opens the gate or garage door. # As you walk up to your front door the door unlocks; it could even trigger the door to open for you as well. # You forgot that your alarm was on, no problem, as ECKey authenticates you, it can disarm the security system and triggers your home automation system. # Provide access to other people without having to leave a key under the mat or getting multiple keys made. Using Multiple ECKey EK3 Relay Units If you plan to install an ECKey EK3 Relay Unit at multiple entry locations on your property, consider using the ECKEY MK3 Management Tool Kit with EK3 Professional Relay. In addition to coming with an ECKey EK3 Relay Unit, it also comes with the software and USB dongle to program and manage each of the EK3 units.
