Stage 1 time
•
Press 'Yes' to accept and step on. Press 'No' to change and then enter the required end time using
the number buttons.

Stage 2 time
( Key in number, then press "Enter"
•
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 'ACCEPT' button within the 30 seconds a full alarm will be generated.
•
Pressing the '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, or if a new fire alarm signal is detected during stage 2, a full fire
alarm will be raised.
•
Finally, the display prompts the zones that are to be used in delayed mode.
---------------------------------------------
Zone[001] to [012] may use day mode
•
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.

The commissioning engineer can adjust the sensitivity of both temperature and smoke detectors by
adjusting the threshold at which pre-alarm and fire alarm signals are generated.

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.
