RTAFHD3 Compatibility
The (G)RTAFHD3 sensor cannot be utilized in combination with the
discontinued (G)RTAF and (G)RTAFH sensors or (G)RTHD sensors built prior to
2010. If you desire to add (G)RTAFHD3 sensors to an existing installation
currently utilizing incompatible sensors, please contact Customer Service for
installation options. (G) indicates Global Sensor variants that may be used
outside of the US.
Connecting Remote Sensors
Plug-and-play remote sensors may be attached to the unit at any time via the
RJ-12 connectors on the face of the unit. In some cases splitters may be
required to add additional sensors. Each sensor has a unique serial number
and is automatically discovered and added to the web page. Up to four
sensors may be connected to the Watchdog 100.
The display order of the sensors on the web page is determined by the serial
number of each sensor. Friendly names for each sensor can be customized on
the Sensors Overview page.
NOTE
Sensors use Cat. 3 wire and RJ12 connectors.
Wiring must be straight-through: reverse polarity will
temporarily disable all sensors until corrected.
Sensors use a serial communication protocol and
are subject to network signaling constraints
dependent on shielding, environmental noise, and
length of wire. Typical installations allow runs of up
to 600 feet of sensor wire.
