Alarm 2 Condition
This section describes the audible and visual indications for an alarm 2
condition and suggests response to an alarm 2 condition.
Alarm 2 Condition Indications
When the gas reading of an active channel reaches the alarm 2 setpoint,
the Rig Monitor senses an alarm 2 condition. The Rig Monitor alerts you to
an alarm 2 condition as follows:
• The ALARM 2 light turns on.
• The gas reading in alarm 2 condition continues to flash and alternates
with the ALARM-2 messages.
• The buzzer sounds a Pulsing tone.
• The common alarm 2 relay energizes.
• The applicable alarm 2 channel relay energizes.
Responding to an Alarm 2 Condition
This section suggests response to an alarm 2 condition.
1. Follow your established procedure for a high level combustible gas
condition.
2. Alarms are latching. After the gas reading falls below the alarm 2
setpoint, press the reset switch to reset the alarm circuit. Resetting the
alarm circuit turns off the ALARM 2 light, and de-energizes the common
and channel alarm 2 relays.
NOTE: To silence the buzzer while in an alarm 2 condition, press the
reset switch.
You cannot de-energize the alarm 2 relays until the gas reading
falls below the alarm 2 setpoint.
