Beacon 800 Gas Monitor Operator’s Manual Alarm Indications • 22
Responding to an Alarm 2 Condition
This section suggests responses to an alarm 2 condition.
1. Follow your established procedure for a high-level combustible or toxic gas condition,
or an increasing oxygen condition.
2. Oxygen alarms are factory set as self-resetting and will automatically clear when the
oxygen reading rises above the alarm 2 setpoint.
3. Alarms for all other gas types are factory set as 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.
Fail Condition
This section describes the audible and visual indications for a fail condition and suggests
responses to a fail condition.
Fail Condition Indications
The Beacon 800 senses a fail condition for any of the following:
• the transmitter wiring is disconnected or incorrectly connected;
• the display reading is -10% of full scale or lower;
• the Beacon 800 or transmitter is malfunctioning.
When the Beacon 800 senses a fail condition, it alerts you as follows:
• the FAIL light turns on;
• the gas reading for the failing channel is replaced by the FAIL message;
• the buzzer sounds a steady tone;
• the common fail relay de-energizes.
NOTE: The fail alarm has a 30 second delay.
NOTE: If you elected to use the channel’s alarm 2 relay as an individual fail relay in the
Configuration menu, the relay de-energizes in a fail condition. See Chapter 5:
Configuration Menu.

This section suggests responses to a fail condition.
