OPC ALARMS AND ALERTS

The following section will cover the OPC Alarm and
Alert modes. This information can also be found on the
backside of the unit (Fig. 24).
The OPC continuously displays its operational STATUS,
and also generates various ALARMS and ALERTS to
indicate critical warnings or error conditions. System
STATUS, ALARM and ALERT conditions are conveyed by
front-panel LEDs. The pattern of flashing LEDs associated
with each condition is intended to be suggestive of the
severity of the condition indicated and otherwise as
obvious as possible. A user should nevertheless become
familiar with the various ALARMS and ALERTS before
using the OPC for the first time, and review periodically.
(See Legend Fig. 25)
The Oxygen Flow Indicator LED (O
Warning LED displays battery-related conditions. An initial oxygen pulse is delivered as part of the
Power-Up Test sequence. Oxygen pulses are subsequently delivered with each inhalation during
normal operation.
Notes:
• Status LEDs flash green for Night Vision Goggle (NVG) compatibility, and are therefore difficult to
see through the NVG. LEDs should be viewed directly (not through the NVG) and the OPC should
be located in such a manner as to make this convenient.
• OPC status should be checked periodically to verify proper operation.
