Detector Head Input Type
Description
4-20 mA TRANSMITTER
A 4-20 mA TRANSMITTER detector head is connected
to the Beacon 410 with 2 or 3 wires, depending on the
detector head model, using the AMP +, S, and - terminals
on the detector/transmitter terminal strips. All calibration
adjustments are made at the detector head.
PREAMP DIRECT
A PREAMP DIRECT detector head is connected to the
Beacon 410 with 2 wires using the AMP + and S
terminals on the detector/transmitter terminal strips. All
calibration adjustments are made at the Beacon 410.
OXYGEN DIRECT (25%)
An OXYGEN DIRECT detector head is an oxygen
detector head in which the oxygen detector is wired to the
Beacon 410 with 2 wires using the OXY W (white) and G
(green) terminals from on the detector/transmitter
terminal strips. All calibration adjustments are made at
the Beacon 410.
RWGB DIRECT (LEL)
An RWGB DIRECT (LEL) detector head is detector head

(black) terminals on the detector/transmitter terminal
strips. All calibration adjustments are made at the
Beacon 410. This type of detector head is typically a
combustible gas LEL detector head, but may be another
type such as a CO
2
detector.
