n PREALARM STATUS
This status indicates that an input point (detector) has
exceeded its alarm threshold. The fire control panel will
not generate an alarm until the preset prealarm- time
ends. However, if a second input point (detector in the
same SW zone) detects alarm conditions during the
Prealarm phase (and the "Double knock" option has
been programmed for that zone), the fire control panel
will generate an instant alarm.
NOTE: If the fire control panel is operating in NIGHT
mode, it will generate INSTANT ALARMS ONLY (Prea-
larm status will be bypassed automatically). If an alarm
procedure is already running, the fire control panel will
ignore prealarm conditions.
PREALARM status will also be signalled by:
Ø blinking PREALARM LEDs;
Ø on fire control panel Display;
Ø an intermittent audible signal on the fire control panel;
Ø the prealarm output points.
During the PREALARM phase you will be able to
SILENCE, INVESTIGATE or RESET the system and
view the LOG.
The Display in Figure 42 shows that fire control panel is
