Methane Elimination Switch
The methane elimination switch (SW1) is mounted near the top right corner
of the main PCB.
For applications where methane is an interfering gas, you can set the methane
elimination switch to eliminate most response to methane (see “Appendix B:
Methane Elimination” on page 58). An external methane elimination switch
is available as an option.
CAL/SETUP Switch
The CAL/SETUP switch (SW2) is mounted near the middle left edge of the
main PCB. This switch controls the Eagle functions available to the user by
disabling the SHIFT/
▼ button. Without the use of this button, the user is
unable to enter Calibration or Setup mode. (Display mode is available with
either switch setting.) See “Setting User Access” on page 18
to change the
switch setting.
Remote Detector
This section describes the Eagle’s Remote Detector. The Remote Detector is
used to detect combustible gas, oxygen, carbon monoxide, and hydrogen
sulfide using four sensors mounted inside a durable plastic case. These
sensors are connected to a printed circuit board, which is also located inside
the case. The Remote Detector includes a buzzer that sounds for gas alarms
and sensor malfunction. The Remote Detector can be connected either
directly to the Eagle, or it can be connected to the Eagle via a 50-foot
extender cable.
Case
The Remote Detector has a durable plastic case with a removable lid secured
by four screws. A removable rubber o-ring gasket mounted in the lid helps
protect the sensors, buzzer, and PCB from water, dust, and the corrosive
effects of gas and vapor.
