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: 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.
Responding to a Fail Condition
This section suggests responses to a fail condition.
1. Verify that the transmitter wiring is correctly and securely connected.
2. See the troubleshooting guide in Chapter 6, Maintenance.
Low Battery Condition
This section describes the audible and visual indications for a low battery condition and
suggests responses to a low battery condition. This condition only applies when DC power
is used as a primary or backup power source.
