Beacon 110 Operator’s Manual 23
Alarm 1 Condition
Alarm 1 Condition Indications
When the gas reading reaches the alarm 1 setpoint, the Beacon 110 senses an alarm 1
condition. The Beacon 110 alerts you to an alarm 1 condition as follows:
• The alarm 1 LED turns on.
• The gas reading alternates with the ALARM-1 message.
• The buzzer sounds a pulsing tone.
• The alarm 1 relay energizes.
• If the optional strobe is installed and set to operate for alarm 1, it flashes.
Responding to an Alarm 1 Condition
1. Follow your established procedure for a low level combustible or toxic gas condition or
a decreasing oxygen concentration condition.
2. Oxygen alarms are factory set as self-resetting and will automatically clear when the
oxygen reading rises above the alarm 1 setpoint.
3. Alarms for all other gas types are factory set as latching. After the gas reading falls
below (or rises above for oxygen) 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 LED, returns the LCD to the normal operation screen, de-energizes the alarm 1
relay, and turns off the strobe if it is installed and set to operate for alarm 1.
NOTE: If the reset switch is pressed while the Beacon 110 is in an alarm 1 condition,
the buzzer will be silenced and the alarm 1 LED will flash. If the strobe is
installed and its alarm 1 operation is set to CanReset in Configuration Mode,
the strobe will turn off.
You cannot de-energize the alarm 1 relay until the gas reading falls below
(above for oxygen) the alarm 1 setpoint.
Alarm 2 Condition
Alarm 2 Condition Indications
When the gas reading reaches the alarm 2 setpoint, the Beacon 110 senses an alarm 2
condition. The Beacon 110 alerts you to an alarm 2 condition as follows:
• The alarm 2 LED turns on.
• The gas reading alternates with the ALARM-2 message.
• The buzzer sounds a pulsing tone.
• The alarm 2 relay energizes.
• If the optional strobe is installed and set to operate for alarm 2, it flashes.
NOTE: If the Beacon 110 is in both an alarm 1 and alarm 2 condition, both the alarm 1
and alarm 2 LEDs will be on, the gas reading will alternate with the ALMS 1&2
message, and both alarm relays will energize.
