GardTec 872 & DD243 : 2002
From the 1st July 2002 DD243 2002 will come into effect in England, Wales and
Northern Ireland replacing the 1999 policy. All communications systems that require a
Police URN will need to conform to DD243:2002.
This document is intended to help installers of the GardTec 872 control panels
understand the new features that have been incorporated into the panels and use
them to ensure that the system complies to the new DD243:2002 requirements. The
advanced DD243 features must be programmed via a LCD keypad.
This document is intended as a guide only and should be read in conjunction with the
relevant standards relating to the alarm system giving particular attention to BS 4737
and DD243. These may be obtained from the British Standards Institute.
To program the confirm options on the GardTec 872 enter engineer mode (1234
default followed by YES) the display will show 'Program Zones' press NO until the
display shows 'Program Alarm Confirm' press YES to enter into this section.
The first option will be
Confirm Time Window (default = 60)
This time window may be programmed between 1 and 120 minutes. To comply the
required time should be between 30 and 60 minutes.
See 5.4.1 DD243:2002 Criteria for sequentially confirmed alarm conditions.
Confirm on Entry (default = On)
This option may be programmed to On or Off. If Confirm on Entry = Off then confirmed
alarms to central station are disabled if the entry timer is started. If ACE is used then it
is permissible to set this option to On.
See 6.4.4 DD243:2002 Opening the initial entry door disables all means of
conformation.
Sounder Mode (default = Unconfirmed)
This option controls the system speakers fitted, options are confirmed or un-confirmed.
If Sounder Trigger = Confirmed then internal sounder will only trigger with a confirmed
alarm.
If Sounder Trigger = Unconfirmed then internal sounders will trigger with un-confirmed
alarms.
This feature is not mandatory for DD243
Reset Mode (default = Any)
Choose from Any or Normal.
If Unconfirm = Any then any code can be used to reset an un-confirmed alarm.
If Unconfirm = Normal then the programmed reset mode for alarm will still be required
i.e. if alarm reset has been programmed as engineer and Unconfirm reset is Normal
then an engineer reset will be required for Un-confirmed alarms.
See A.4 DD243:2002 Resetting following an alarm condition.
