Alarm 1 Condition
This section describes the audible and visual indications for an alarm 1
condition and suggests response to an alarm 1 condition.
Alarm 1 Condition Indications
When the gas reading of an active channel reaches the alarm 1 setpoint,
the Beacon 200 senses an alarm 1 condition. The Beacon 200 alerts you to
an alarm 1 condition as follows:
• The ALARM 1 light turns on.
• The gas reading in alarm 1 condition flashes and alternates with the
ALARM-1 message.
• The buzzer sounds a pulsing tone.
• The common alarm 1 relay energizes.
• The applicable alarm 1 channel relay energizes.
Responding to an Alarm 1 Condition
This section suggests response to an alarm 1 condition.
1. Follow your established procedure for a low level combustible or toxic
gas condition or a decreasing oxygen content condition.
2. Oxygen alarms are self-resetting and will automatically clear when the
oxygen rises above the alarm 1 setpoint.
3. Alarms for all other gas types are latching. 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, resets the channel display, and de-energizes the
common and channel alarm 1 relays.
NOTE: To silence the buzzer while in an alarm 1 condition, press the
reset switch.
You cannot de-energize the alarm 1 relays until the gas reading
falls below (above for oxygen) the alarm 1 setpoint.
