may activate and an audible alarm may sound if those
features have been enabled ( Section 4.2., E2,
Einstein, and REFLECS Controllers (The RLDS

An inverse flashing box indicates an alarm condition
in the affected zone.
You can investigate the status of the affected zone
further by selecting the ALARM option on the Status

7.5. Fault Conditions
If a system malfunction occurs, the yellow FAULT
LED will glow. Additionally, an external alarm
(
Section 4.2., E2, Einstein, and REFLECS
Controllers (The RLDS Gateway Board)
) device
may activate and an audible alarm may sound if those
features have been enabled (
Section 6.8., Audible

).
7.6. Alarms
7.6.1. Functional Overview
If the PPM level for any zone exceeds its designated
spill, leak, or evacuate thresholds, an alarm condition
will be created. Once the RLDS completes a
measurement cycle in the affected zone the alarm
condition will be indicated. At that time the red
ALARM
LED on the RLDS will glow. Additionally,
an external alarm device may activate and an audible
alarm may sound if those features have been enabled
( Section 6.8., Audible Alarm ).
7.6.2. Responding to Alarms
An operator can respond to alarms by accessing the
Alarm Summary screen . Navigate to this screen by
selecting
ALARM
on the Data Display screen
( Figure 6-1 ).
Alarm Summary Screen
The
Alarm Summary screen
displays a list of all alarm
conditions pending across the network. The screen is
divided into eight (8) boxes, and each box represents
a single alarm. If more than eight (8) alarms are
pending, the MORE option will be displayed at the
bottom of the screen to permit access to that
additional information.
Each box displays the zone number, zone name, and
the current PPM reading. A flashing box indicates an
alarm that has not been acknowledged. A static box
represents an alarm that has been acknowledged but
has not yet been cleared from the system.
