4.4.4. 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.
Figure 4-5. Alarm Summary Screen (Acknowledge Mode)
Once all the alarms associated with a given MZ monitor are acknowledged, its RED LED will turn off and
any external alarms connected to the MZ relays will de-activate. All pending alarms across the entire
network must be acknowledged before the Remote Display returns to normal operation. Once that occurs,
its RED LED will turn off and any associated external alarms connected to the 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.
4.4.5. 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 “P RESS ENTER TO CONFIRM
SILE NCE ”. When ENTE R 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 SP ILL 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. “Silence mode” will be
automatically canceled if the alarm condition of any zone changes by clearing or elevating to a higher
level.
