Setting Alarm Thresholds
There are two (2) sets of Alarm Limits that are of general
use in FLEX for each Badge. These are called “Monitor
Preset A and B.” Monitor Preset A establishes one full set
of Alarm Limits and thresholds, noted on the screen below.
Monitor Preset B establishes another full second set of
Alarm Limits and thresholds. These sets A and B can be
usedwithdifferentroomProles,suchasOCCUPIEDand
UNOCCUPIED states, where the user may desire different
Alarm Limits.
For example: OCCUPIED may have thresholds for 0.03”
WC Pressure, 68 °F Temperature, and 20 ACH. But
UNOCCUPIED would not need those higher thresholds,
and may only need thresholds 0.01” WC Pressure, 75 °F
Temperature, and 8 ACH.
Decide whether you will need one or two sets of Alarm
Limits, and use only Monitor Preset A, or whether you will
need a second set, Monitor Preset B. Set parameters for
one, or both. When the radio button for Monitor Preset B
is pressed, all new Alarm Limits can be entered on that
screen.
Low Limit is the low threshold for alarming. High Limit is
the high threshold for alarming. For a Positive room you
may not need a High Limit. If this is the case, change the
state of High Alarm Enabled to Disabled. For a Negative
room, you may not need a Low Limit. If this is the case,
change the state of Low Alarm Enabled to Disabled.
Alarm Delay is the time between when a parameter value
falls beyond an alarm condition (trigger) and when an
audible, visual, or output alarm condition occurs. Use
Alarm Delay when time is needed for door entry and
personnel access. Return to Normal Delay is just the
opposite. When a parameter value comes out of alarm
and now falls within normal range, the audible, visual, and
output alarm condition will persist for this period of time
until the condition is cleared.
Deadband is a value that is added or subtracted to a limit
when determining if a parameter has returned to a normal
state. For example. Given a pressure parameter with a low
alarm limits of 0.1”WC, and deadband of 0.01”WC, if the
pressure falls below 0.1”WC and goes into an alarm, the
pressure must then return to a value greater than 0.11”WC
to trigger the alarm state change from alarm to normal.
3.8 Room Prole
The Room Prole Setup menu is where the functions of
the Home screen Proles pull-down menu are dened.
There are four (4) fully congurable Room Proles, and
