22 • Operation Pioneer Gas Monitor Operator’s Manual
NOTE: The alarm 3 relay does not energize if you elect to use it as the channel’s fail relay
in the Channel Setup program (see the “Channel Setup Program” section of the
applicable detection insert in Appendix B, Gas Detectors.)
Responding to an alarm 3 condition
This section suggests response to an alarm 3 condition.
1. Follow your established procedure for a high level combustible or toxic gas condition
or an increasing oxygen content condition.
2. After the gas reading falls below the alarm 3 setpoint, press the reset switch to reset
the alarm 3 circuit. Resetting the alarm 3 circuit turns off the ALARM 3 light, and
de-energizes the common and analyzer card alarm 3 relays.
NOTE: To silence the buzzer while in an alarm 3 condition, press the reset switch.
You cannot de-energize the alarm 3 relays until the gas reading falls below the
alarm 3 setpoint.
Fail Condition
This section describes the audible and visual indications for a fail condition and suggests
response to a fail condition.
Fail condition indications
The Pioneer senses a fail condition for any of the following:
• the detector wiring is disconnected or incorrectly connected
• the analyzer card is disconnected or incorrectly connected
• the display reading is below the fail setpoint
• the monitor or detector is malfunctioning
When the Pioneer senses a fail condition, it alerts you as follows:
• the FAIL light turns on
• the gas reading in fail condition flashes
• the buzzer sounds a steady tone
• the common fail relay de-energizes
NOTE: If you elected to use the analyzer card’s alarm 3 relay as an individual fail relay
in the Channel Setup program, the relay de-energizes in a fail condition.
(See the “Channel Setup Program” section of the applicable detection insert in
Appendix B, Gas Detectors.)
Responding to a fail condition
This section suggests response to a fail condition.
1. Verify that the detector wiring is correctly and securely connected.
2. Verify that the analyzer card is securely and correctly installed. (The components of
the analyzer card face left when the analyzer card is correctly installed.)
3. See the troubleshooting guide in the applicable detection insert (Appendix B,
Gas Detectors).
