Loop Response; Daylight Savings Time; Clock Adjust; Timebase - DSC Power 864 Installation Manual

Auto-Arming and Keyswitch arming will also be prevented in the
presence of any system tamper or zone fault.
NOTE: The Auto Arm cancellation code will not be trans-
mitted if arming is inhibited due to a system tamper or
zone fault.

5.22 Loop Response

The normal loop response time for all zones is 400 milliseconds.
The panel will not consider a zone violated unless it is violated for
at least 400 milliseconds.
If Zone 1 is Fast Loop Response is enabled, the loop response
for zone 1 will be 40 milliseconds. Typically this can be used for
vibration type sensors.
Zone 1 is Fast Loop Response. . . . . . . Section [013], Option [5]

5.23 Daylight Savings Time

If the Daylight Savings Time option is enabled, the panel will
follow the daylight savings time change. At 2 a.m. on the first
Sunday in April, the panel clock will be set forward one hour to 3
a.m. At 2 a.m. on the last Sunday in October, the panel clock will
be set back one hour to 1 a.m.
NOTE:Events programmed to occur between 2 and 3 a.m.
will not occur on the first Sunday in April. Events pro-
grammed to occur between 1 and 2 a.m. will occur twice on
the last Sunday in October.

5.24 Clock Adjust

In order to compensate for timing inaccuracies, you can program
the panel to add or subtract seconds to the clock during the last
minute of each day, using the Clock Adjust programming sec-
tion. Valid entries are 01 - 99. The default setting is 60 seconds.
Example #1: The clock loses an average of 9 seconds per day.
Solution: Program the panel to adjust the clock by 51 seconds
(instead of the default 60 seconds) for the last minute of each
day in section [700]. This will speed up the panel's clock by 9 sec-
onds, correcting the problem.
Example #2: The clock gains an average of 11 seconds per day.
Solution: Program the panel to adjust the clock by 71 seconds
(instead of the default 60 seconds) for the last minute of each
day in section [700]. This will slow down the panel's clock by 11
seconds, correcting the problem.
NOTE:If the Auto-arm time is set for 23:59, any change to the
Clock Adjust option will directly affect the Auto-arm pre-alert
time.

Timebase

In cases of unstable AC power input you can use the internal
crystal to keep a more accurate timebase by enabling the Time-
base is Internal Crystal option.
If the 50 or 60Hz AC power input is very stable it can be used as
the timebase, by enabling the Timebase is AC line option.

5.26 LINKS1000/GSM1000 Cellular
Communicator
The LINKS1000/GSM1000 cellular communicator can be used
three different ways: as the sole communicator for the panel, as
a back up for either or both telephone numbers, or as a redun-
dant back up to the land line communicator (the panel will call
both the land line and via the LINKS1000/GSM1000). A
LINKS1000/GSM1000 Preamble is programmable for each tele-
phone number in the event that the land line number is local but
the LINKS1000/GSM1000 is required to dial an exchange. When
programming a LINKS1000/GSM1000 Preamble, all unused digits
must be programmed with a hex decimal "F".
NOTE: The GSM1000 cannot be used for downloading.
Sole Communicator
The panel can be programmed to report only using the
LINKS1000/GSM1000 cellular communicator when an event
occurs. To program this select only the LINKS1000/GSM1000 for
the Communicator Call Direction Options for the event. In
addition the Call LINKS1000/GSM1000 as well as Land Line
option must also be enabled.
When the selected event occurs the panel will only attempt to
call central station using the LINKS1000/GSM1000.
NOTE: If a LINKS1000/GSM1000-only event fails to commu-
nicate, the LINKS1000/GSM1000 must successfully commu-
nicate a LINKS1000/GSM1000-only event in order for the
FTC trouble to clear.
Backup Communicator
The panel can be programmed to call using the LINKS1000/
GSM1000 cellular communicator if the panel is having difficulty
communicating an event using the land line. To program this
select both the telephone number and LINKS1000/GSM1000
options for the Communicator Call Direction Options for the
event. In addition the LINKS1000/GSM1000 is Backup of Land
Lines option must be selected.
When used as a backup communicator the panel will attempt to
call the central station in the following manner:
• the panel will try to call using land lines - if unsuccessful the
panel will try to call using the LINKS1000/GSM1000
• if unsuccessful the panel will try to call using the land lines
• if unsuccessful the panel will try to call using the LINKS1000/
GSM1000
This process will continue until the panel has successfully com-
municated with the central station or the Maximum Dialing
Attempts has been reached.
Redundant Communicator
The panel can be programmed to call using both the land line
and the LINKS1000/GSM1000 cellular communicator when an
event occurs. To program this select both the telephone number
and the LINKS1000/GSM1000 options for the Communicator
