•
In the above example, the internal warning buzzer will sound and the sensor location will be shown on the display
immediately a fire is detected. If this Stage 1 alarm is not acknowledged at the panel by pressing the "MUTE /
ACCEPT" button within the 30 seconds a full alarm will be generated.
•
Pressing the “MUTE / ACCEPT” button within this period will cause stage 2 to be entered.
•
The stage 2 timer will start counting down as soon the panel detects an alarm signal (i.e. starts at the same time
as stage 1). Setting the stage 2 time for a longer period than stage 1 provides the user with the opportunity to
investigate the cause of the alarm and take appropriate action. If the panel is not reset by the time stage 2 has
expired, a full fire alarm will be raised.
•
Finally, the display prompts the zones that are to be used in delayed mode.
Zone[01] to [12] run in day mode [FALSE]
•
The above example shows that zones 1 to 12 inclusive will not use the day mode times and hence, a fire alarm
will be generated immediately any sensor in these zones detects a high sensor reading.
•
To change the zones, use the
‘<
’ or
‘>
’ to select the appropriate field. Use the number keys to change the zone
numbers. Use the Change key to toggle between [TRUE] and [FALSE].
The user can choose to enable and disable the delayed day mode at level 2. This is as
described in the user manual.
•
Note that for compliance with EN54 the maximum total delay is 10 minutes, therefore the stage 2 delay plus any
sounder delay must not exceed this time.
