Fail Condition
This section describes the audible and visual indications for a fail condition
and suggests response to a fail condition.
Fail Condition Indications
The 12 VDC Beacon 200 senses a fail condition for any of the following:
• The detector head wiring to the 12 VDC Beacon 200 is disconnected or
incorrectly connected.
• The detector head’s detector is disconnected or incorrectly connected.
• The display reading is -10% of full scale or lower.
• The 12 VDC Beacon 200 or detector head is malfunctioning.
When the 12 VDC 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 “Chapter 5: Channel Control and
Setup Program” on page 28 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 12 VDC 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 Power Condition
Most 12 VDC power sources’ output voltage will decrease too quickly in a
low power condition for the 12 VDC Beacon 200 to recognize a low power
condition before it shuts down. As a result, when the 12 VDC Beacon 200
is used with a 12 VDC power source, there may be no low power alarm and
