2.1.5 Powering Up and Shutting Down the WD
The WD is delivered in a shutdown state for safety reasons and to save battery. While in this
state, the motion sensing capabilities and the wireless radio are shutdown, and the device is
ready to receive the LF command to power up and join a wireless ZigBee network.
1. To power up and join the device to a wireless network that has already been formed by
a WG, use the WH as described in the specific WH IOM sending the JOIN (or JOIN
ALL) command to the WD.
When the WD powers-up, a distinct flashing sequence of the LEDs is visible. The operation
normally takes a few seconds. During this sequence, the WD validates that the battery has
sufficient power for the initial process. If this is not the case, the power-up sequence might take
longer (during which the LEDs are still flashing), until the power levels are stable.
If the power on sequence takes longer than 4 minutes, replace the battery pack. If power up
does not complete, contact your local distributor. For additional information, refer to
Troubleshooting chapter.
