1. Take the KWX unit to be connected to the master controller and designate this unit the Master
Transceiver.
2. Position the Master Transceiver in the desired location near the master controller location using
the following criterion:
- Mount the unit at least 7 feet above the floor; the higher the unit is mounted, the greater the
signal strength.
- The unit must be mounted upright for proper signal coverage (refer to the unit label – see
Figure 5 on page 7).
- Do not mount the unit on to or beside metal and ensure the unit is not obscured by large metal
objects (such as HVAC units and ducts, building supports and poles, etc.).
- Ensure you will be able to route the unit cables to the controller.
The Master Transceiver must be located central to all Remote Transceivers. All Transceiver
communication occurs between the Master and the Remote Transceivers. Remote Transceivers do
not communicate with each other.
3. Provide 12 VDC power to the Master Transceiver using a gel cell battery or a DC power supply.
The Power LED will light-up solid amber.
4. Turn the Test Mode Switch ON. The Test Mode Active LED will flash red and the Master
Transceiver will begin transmitting test data packets.
5. Take a second KWX unit and designate this unit the Remote Transceiver. Leave the Test Mode
Switch on the Remote Transceiver OFF.
6. Position the Remote Transceiver in a desired mounting location near a controller on an access
control network spur using the same criterion as in Step 2. The two units must be mounted greater
than 10 feet apart.
NOTE: Transcievers must be placed greater than 10 feet apart from each other. Unit-to-unit
interference may be generated if units are placed closer than 10 feet from each other.
7. Provide 12 VDC power to the Remote Transceiver using a gel cell battery or a 12 VDC power
supply. The Power LED will light-up solid amber.
8. Ensure the Test Mode Switch on the Remote Transceiver is OFF.
