Acknowledging Alarms
Each pending alarm may require, depending upon selected alarm mode, acknowledgment before the system
returns to normal operation (refer to
Alarm Ack Mode on page 26). To acknowledge an alarm, navigate to the
Alarm Detail Screen and select the ACK option as previously described. You will then be returned to the
Alarm Summary Screen and the box associated with that alarm will no longer be blinking, indicating that the
alarm has been acknowledged. Repeat this procedure to acknowledge any remaining alarms.
Alarm Summary Screen (Acknowledge Mode)
Once all the alarms associated with a given AGM-MZ are acknowledged, its RED LED will turn off and any
external alarms connected to the AGM-MZ relays will de-activate. All pending alarms across the entire
network must be acknowledged before the AGM-RD returns to normal operation. Once that occurs, its RED
LED will turn off and any associated external alarms connected to the AGM-RD relays will de-activate.
Keep in mind that the system will continue to generate new alarms if PPM values above the alarm thresholds
are detected.
Silencing an Alarm
When alarms are active, the ESC key functions as a silence key. During an active alarm and with the main
screen displayed, press the ESC key. This will generate a prompt to "PRESS ENTER TO CONFIRM
SILENCE". When ENTER is pressed, the LEAK relay will open and the internal audible alarm (if enabled)
will turn off. In this way, when the LEAK relay is used to operate strobes and horns, they can be quickly
silenced without effecting the SPILL or EVAC, which may be controlling fans or ventilation equipment. This
'silence' mode will be indicated by a reverse flashing 'S' in the alarm window. The 'silence' mode will be
automatically canceled if the alarm condition of any zone changes by clearing or elevating to a higher level.
System Faults
Functional Overview
If a system malfunction occurs, the yellow FAULT LED will glow. Additionally, an external alarm device may
activate and an audible alarm may sound if those features have been enabled (pages 25 & 29).
The next time the AGM-RD polls the affected monitor its yellow FAULT LED will also glow. Additionally, an
external alarm device may activate and an audible alarm may sound if those features have been enabled
(pages 25 & 29).
