32 • Alarm Indications
incorrectly connected.
• The detector head’s detector is disconnected or incorrectly connected.
• The display reading is -10% of full scale or lower.
• The Beacon 200 or detector head is malfunctioning.
When the Beacon 200 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 Channel Control & Setup menu, the relay de-
energizes in a fail condition. See the Channel Control & Setup
section of Chapter 5 for a description of this setting.
Responding to a fail condition
This section suggests response to a fail condition.
1. Verify that the detector head wiring to the Beacon 200 is correctly and
securely connected.
2. Verify that the detector head’s detector is correctly and securely
connected.
3. See the troubleshooting guide in the detector head instruction manual.
Low Battery Condition
This section describes the audible and visual indications for a low battery
condition and suggests response to a low battery condition. This condition
only applies when DC power is used as a primary or backup power source.
NOTE: When a 24 VDC battery is used as a backup power source, the
Beacon 200 keeps the battery charged by providing a trickle
charge from the AC power source. If AC power is interrupted, the
Beacon 200 will operate from the DC backup battery until the
battery voltage drops to 21.5 volts or less, or until AC power is
restored.
