8.4. Alarm Conditions

When an alarm condition is detected anywhere on the
network, the red ALARM LED will glow on the front
of the unit. Additionally, an external alarm 
device may activate and an audible alarm may sound
if those features have been enabled (Section 4.2., E2,
Einstein, and REFLECS Controllers (The RLDS
Gateway Board).
An inverse flashing box indicates an alarm condition
in the affected zone.
You can investigate the status of the affected zone fur-
ther by selecting the ALARM option on the Status
screen (Figure 7-2).

8.5. Fault Conditions

If a system malfunction occurs, the yellow FAULT
LED will glow. Additionally, an external alarm (Sec-
tion 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 7.8., Audible
Alarm).

8.6. Alarms

8.6.1. 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 7.8., Audible Alarm).
The alarm condition may or may not have to be 
acknowledged for the system to return to normal 
operation.

8.6.2. Responding to Alarms

An operator can respond to alarms by accessing the
Alarm Summary screen. Navigate to this screen by se-
lecting ALARM on the Status screen 1
(Figure 7-2).

Figure 8-3 - 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 pend-
ing, additional pages can be displayed by selecting the
MORE option (visible when there are more than
eight (8) alarms pending).
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.
The Alarm Data Log can be reset by pressing a com-
bination of the ENTER and right arrow buttons while
viewing the log.
