-
The ALARM 1 light turns on
- The gas reading in alarm 1 condition flashes
- The buzzer sounds a pulsing tone
- The common alarm 1 relay energizes
- The alarm 1 relay on the applicable analyzer card energizes
• Responding to an alarm 1 condition
-
Follow your established procedure for a low level combustible or toxic gas condition or a
decreasing oxygen content condition.
- After the gas reading falls below the alarm 1 setpoint, press the reset switch to reset the alarm 1
circuit. Resetting the alarm 1 circuit silences the buzzer, turns off the ALARM 1 light, and de-
energizes the common and analyzer card alarm 1 relays.
