COMPLIANCE WITH SPECIFIC
REQUIREMENTS
a) Basic Operation
Normal operation of a
"Sequentially Confirmed"
system requires the following
signals to be sent to the ARC:
Intruder (03) at first alarm
Confirmation
(06)
at second valid
alarm
Zone omit at
Rearm (17)
in the event of
a zone being
omitted at
Reinstatement
of the system
at the end of
confirmation
time
Set/Unset (04)
OR
When system
sets / unsets
Misoperation
(05)
When system
manually unset
following an
alarm.
These output configurations
are programmable as required
(see 13-27).
These are available on a system-
wide ("ANY") - type number
references as above -or per
area ("AREA") as required.
Local responses of the system
should be set up in the "Alarm
responses menu, see page 13-
25.
Note particularly the following
option available:
'Silent First Alarm:'
all sounder and siren outputs
remain silent until an alarm is
confirmed. This could be used
for an audio-confirmed system
for example, if the audio
confirmation equipment did
not include the facility to
interrupt these outputs.
If such a situation, feedback
from that equipment would be
required to simulate a
"sequentially" confirmed alarm
in order to trigger the panel
sounders and sirens.
Additionally, the following
TIMERS are required (page 13-
17):
"Pre-Alarm" Time should be set
to 30 seconds (or equal to entry
time if shorter) for correct
operation.
"Confirmation" Time should be
set as required, noting that
DD243:2002 specifies between
30 and 60 minutes.
NOTE: DD243:2002 permits the
"Confirmation" timer to be re-
started in the event of a second
trigger of the 'first detector'
during confirmation time.
This option is NOT available on the
Euro-MERiDIAN range.
