11.2.1
Commissioning Delayed Mode
•
Press 1 to select Delayed mode from the 'Day Modes Menu.
The display will prompt
whether the mode is to be
used.
•
Press No to inhibit the mode and return to the 'Day Mode' menu.
•
Press Yes to enable the mode.
The display will then prompt
the start and end times for the
day period.
•
Press Yes to accept and step on.
•
Press No to change and then
enter the required start time
using the number buttons.
•
Press Yes to accept and step on. Press No to change and then enter the required end time using the
number buttons.
•
A two stage timer is built into the day mode.
•
After entry of the start / end
times, the display prompts the
stage timers as follows:
•
Press Yes to accept and step on.
Press No to change and then
enter the required end time
using the number buttons.
•
Immediately a fire is detected. If this Stage 1 alarm is not acknowledged at the panel by pressing the
"TROUBLE SILENCE" button within the 15 seconds a full alarm will be generated.
•
Pressing the "TROUBLE SILENCE" 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.
•
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.
Per NFPA 72 1999, paragraph 1-5.4.11 the maximum times for the Stage 1 and Stage 2
timers are as follows:
Stage 1 = 15 seconds
Stage 2 = 180 seconds
