Remote Mounting
The RXT-320 wireless transceiver is normally connected directly to the J-Box containing the battery/terminal
board assembly. In situations where RF line-of-sight is diminished by obstructions, it may be necessary to
remotely mount the wireless transceiver away from this J-Box. Remote separation distances of up to 15 feet
are possible with the recommended cable. Such an installation will require an additional J-Box which
connects to the separated transceiver and houses Detcon’s 8-position terminal board with Ground board plus
additional hardware (See Figure 10).

RXT-300 Wireless Transceiver Remote Mounting
A custom extension cable needs to be built per Figure 11 to interface the remote transceiver to the Model 100
Terminal Board. The recommended cable for remote transceiver separation is Belden 1421A (24AWG
shielded twisted pair, 4 pairs w/drain wire).
NOTE:
It is highly recommended to install the extension cable inside rigid metal conduit to
eliminate potential EMI and RFI interference and to maintain a Class I Division I rating.
NOTE:
Color coding of the cable will no longer match the color coding on the Model 100
Terminal Board for the J1 connector.
