A. Acknowledge the displayed point or acknowledge all points on the list (Global
Acknowledge).
B. Scroll the points chronologically after all points have been acknowledged.
When Global Acknowledge is used on the 4100 system, a single key press will
acknowledge all fault changes in the system. If status change information is
required, the user may review this data (after a delay) by pressing the <ACK>
key and reading the total number of fault changes on the alphanumeric display.
If a fault condition has been acknowledged with the <ACK> key and further
unacknowledged fault conditions remain in the system, the tone-alert continues
to sound and the next status change is shown on the alphanumeric display.
NOTE: Normally, points may not require acknowledgment and do not latch. If the
system does not clear, read the display, then check for devices still in fault
(manual call points, smoke detectors etc.).

SYSTEM RESET TO CLEAR FAULTS

Some faults latch until they are reset manually or can be cleared by pressing the
<SYSTEM RESET> key once the fault condition has been rectified. This applies to
Open Circuit faults on MAPNET and RUI communications lines.
If a monitor point or device intermittently toggles faults or will not reset, the user may
elect to ISOLATE the faulty zone or disable the faulty device (refer section 3.3 for
isolate procedures).

FAULT INDICATIONS FOR TrueAlarm™ SENSORS
The devices that are used for TrueAlarm™ operation are considered sensors instead
of detectors, because these devices do not determine alarm conditions. The
TrueAlarm™ smoke sensor is a measuring device that sends data regarding smoke
density to the 4100 control panel. The TrueAlarm™ heat sensor operates in a similar
fashion, but sends temperature data instead of smoke density data. The 4100 uses
this data to determine whether a fault has occurred. This basic operational difference
is the key to TrueAlarm™ operation.
The TrueAlarm™ sensor has two automatic fault conditions:
Dirty, and
Excessively Dirty
