Connecting a Recorder
The recorder output terminals will accept 24 - 14 AWG wire. Select wire
that is rated to a minimum of 80°C, 0.2 A, and 150V.
Perform the following procedure to connect an analog recording device to
the Beacon 200. The output at the recorder output terminals is a 4 - 20 mA
signal that is proportional to the detection range of the applicable detector
head.
1. Turn off or disconnect mains power to the Beacon 200.
2. Open the housing door, then place the power switch in the OFF
position. Locate the recorder output terminals on the controller terminal
strip (see Figure 1).
3. Install an appropriately rated cable bushing or conduit in an unused
conduit hub on the bottom of the Beacon 200 housing.
4. Guide the wiring from the recording device through the selected
conduit hub on the Beacon 200.
