Chapter 2: Description
Overview
This chapter describes external and internal components of the Pioneer Gas Monitor.
External Description
This section describes the housing and all external components of the Pioneer. For the
purposes of this description, the housing door is considered the front of the monitor.
Housing
The Pioneer’s fiberglass housing is weather- and corrosion-resistant. It is suitable for
installation where general purpose equipment is in use. The housing door is hinged on
the left side and is secured by two latches on the right side. The display screen and status
lights are visible through a window in the housing door. Four mounting feet are attached
to the back of the housing (one at each corner). The mounting feet allow you to install the
housing to a vertical surface. Four conduit hubs on the bottom of the housing are for
external wiring connections.
CAUTION: To avoid electrical interference, do not route detector and power wiring through the
same conduit hub. Always install a 3/4 in. NPT conduit plug in any unused hub.
See Appendix A. Parts List, for ordering information.
Buzzer
The buzzer is on the bottom of the housing. It is behind the reset switch. The buzzer
sounds audible alarms to warn you of gas alarms and instrument failures.
Reset Switch
The reset switch is on the bottom of the housing. It is in front of the buzzer. The reset
switch serves three functions:
• You can reset the alarm circuits for “latched” alarms after an alarm 1, alarm 2, or
alarm 3 condition passes.
• If the alarm silence setting is ON in the Instrument Setup program, you can silence the
buzzer during an alarm 1, alarm 2, or alarm 3 condition. You cannot silence failure
alarms.
You can adjust the alarm silence setting in the Instrument Setup program
(see Chapter 4, Operation).
• You can run the Display Setpoints and Readings program (see Chapter 4, Operation).
