the alarm 1 circuit. Resetting the alarm 1 circuit silences the buzzer, turns off the
ALARM 1 light, and de-energizes the alarm 1 relay.
NOTE: To silence the buzzer while in an alarm 1 condition, press the reset switch.
You cannot de-energize the alarm 1 relay until the gas reading falls below (above
for oxygen) the alarm 1 setpoint. Once the gas reading falls below the alarm 1
setpoint, if the reset button has been previously pressed the alarm 1 relay will de-
energize.
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 Beacon senses
an alarm 2 condition. The Beacon 100 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
• the buzzer sounds a faster pulsing tone than an alarm 1 condition
• the alarm 2 relay energizes
Responding to an alarm 2 condition

the alarm circuit. Resetting the alarm circuit turns off the ALARM 2 light, and
de-energizes the alarm 2 relay.
NOTE: The alarm 2 condition cannot be silenced. The reset switch must be pressed after
the gas reading falls below the alarm 2 level in order to de-energize the alarm 2
relay.
