Table 10: 12 VDC Beacon 200 Detector Head Types
Detector Head Type Description
4 - 20 mA Amp [+S(-)] A 4 - 20 mA detector head is connected to the 12 VDC
Beacon 200 with 2 or 3 wires, depending on the detector
head model, using the AMP/PREAMP +, S, and - terminals
on a detector head terminal strip. All calibration adjustments
are made at the detector head.
PreAmp [+S] A PreAmp detector head is connected to the 12 VDC Beacon
200 with 2 wires using the AMP/PREAMP + and S terminals
on a detector head terminal strip. All calibration adjustments
are made at the 12 VDC Beacon 200.
O2 Direct [+-] An O2 Direct detector head is an oxygen detector head in
which the oxygen detector is wired to the 12 VDC Beacon
200 with 2 wires using the OXYGEN + and - terminals on a
detector head terminal strip. All calibration adjustments are
made at the 12 VDC Beacon 200.
LEL Direct [RWGB] An LEL Direct detector head is a combustible gas detector
head in which the combustible gas detector is wired to the 12
VDC Beacon 200 with 4 wires using the LEL R, W, G, and B
terminals on a detector head terminal strip. All calibration
adjustments are made at the 12 VDC Beacon 200.
