Chapter 4: Operation Overview This chapter describes the Beacon 800 Gas Monitor in normal operation. This chapter also describes the Beacon 800 in alarm 1, alarm 2, and fail conditions, and suggests responses to these conditions. Normal Operation Normal operation is defined as follows: • the start-up procedure is complete. • the Beacon 800 is not indicating an alarm 1, alarm 2, or fail condition. • the Beacon 800 is not running the Configuration menu.
Alarm Indications This section describes the Beacon 800 in alarm 1, alarm 2, and fail conditions, and suggests responses to these conditions. Table 4 lists the alarm indications for each condition. NOTE: The Beacon 800 includes alarm on and alarm off delay settings for each channel and level of gas alarm. The alarm indications described in this section operate according to the default delay settings.
Alarm 1 Condition This section describes the audible and visual indications for an alarm 1 condition and suggests responses to an alarm 1 condition. Alarm 1 Condition Indications When the gas reading of an active channel reaches the alarm 1 setpoint, the Beacon 800 senses an alarm 1 condition.
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.
NOTE: When a 24 VDC battery is used as a backup power source, the Beacon 800 keeps the battery charged by providing a trickle charge from the AC power source. If AC power is interrupted, the Beacon 800 will operate from the DC backup battery until the battery voltage drops to 21.5 volts or less. Low Battery Condition Indications The Beacon 800 senses a low battery condition when: • AC power is disconnected, misconnected, or interrupted AND • the DC power source is 21.5 volts or less.
