GM1212 Geist Watchdog Wi Instruction Manual
alternative communications channels. While it is not difficult to switch the channels on
which your system is communicating, it is outside the basic Watchdog Wi configuration
scope. For this reason, we are providing a specialized set of instructions and encourage
you to contact our technical support staff if you have any problems configuring alternate
channel communications.
Watchdog Wi Sensor Communications
By default, Watchdog Wi sensors communicate via channel pair 1. You can determine on
which channel pair your sensor(s) are communicating by looking at the status LED on the
front of the sensor enclosure. This LED blinks randomly once every 10 - 20 seconds. If the
LED blinks blue, the sensor is communicating on channel pair 1. If the LED blinks green,
the sensor is communicating on channel pair 2.
Change the Sensor’s Channel Pair
Hold the sensor in your hand and locate the LED on the top of the enclosure. Make sure
the LED on the board is blinking blue to indicate it’s currently communicating via channel
pair 1. Now look down the side of the enclosure past the LED (the left side of the
enclosure) and find the small hole in the middle of the bottom left side of the enclosure -
right where the lid meets the base. If you look inside this hole you will see a small black
button. You will use this button to change the channel pair of this sensor.
Figure 4-39 Sensor Channel Pair Button
Insert a small non-conductive tool - like a toothpick - inside the hole and push the black
button three times consecutively. The LED on the sensor board blinks blue with the first
push, blue with the second push, and green with the third push. It will then blink green
three times in a row to indicate the sensor has switched to channel pair 2 for its
communications. Pause a minute and watch the sensor LED. Once the transition pattern of
blinks are complete, it blinks randomly, once every 10 - 20 seconds. Wait until it blinks
green once to ensure channel pair 2 communications are active. You can change the
sensor back to channel 1 communications in the same way. If the sensor is operating on
channel pair 2 (LED is blinking green), push the black button three times consecutively.
The LED blinks green with the first push, green with the second push, and blue with the
third push. Then it blinks blue three times in a row to indicate it’s communicating on
channel pair 1. Pause a minute to watch the LED and ensure it’s blinking blue in its random
blink cycle. If you remove or change the sensor’s battery, it will revert to the default
channel pair 1 (blue blinking light).
Manager Communications
By default, the Watchdog Wi communicates via channel pair 1. If you change the channel
pair on which your sensors are communicating, you also need to change the channel pair
