Telephone Line Monitoring (Tlm); Test Transmissions - DSC Power 864 Installation Manual

incoming calls for downloading provided the following condi-
tions occur:
1. The panel hears one or two rings then misses a ring.
2. At this point the panel will start a timer.
3. If the panel hears another ring before the Answering
Machine Double Call Timer expires it will answer on the
first ring of the second call.
The panel will immediately go on line and begin the download
process unless the Call Back option is enabled. If enabled, the
panel and computer will both hang up. The panel will then call
the Download Computer Telephone Number and wait for the
computer to answer. Once the computer answers downloading
will begin.
If the User Enabled DLS Window option is ON, the user can
activate the downloading feature for a set period of time by
entering [*][6][Master Code][5].
If the Full 6-hour User Enabled DLS Window option is
enabled, when the user opens the DLS window with [*][6][Mas-
ter code][5], the DLS window will remain open for six hours. The
DLS window will remain open after a successful hang-up from a
downloading call. If the One Time 1-hour User Enabled DLS
Window option is enabled, when the user opens the DLS win-
dow with [*][6][Master code][5], the DLS window will stay open
for one hour, and will close after a successful hang-up from a
downloading call.
After six hours upon power up, the panel will not answer incom-
ing calls unless the Answering Machine/Double Call option is
enabled, or the Number of Rings is programmed to be more
than [0].
If the User Initiated Call-Up option is enabled, the user can
have the panel initiate a call to the downloading computer by
pressing [*][6][Master Code][6].
The Download Access Code and Panel Identifier Code are for
security and proper identification. Both the panel and the com-
puter file should have the same information programmed before
attempting to download.
The time to complete a successful download can be significantly
reduced with the use of the PC-Link. This adaptor makes it possi-
ble to perform on-site downloading. To Initiate Local Down-
loading via the PC-Link, enter [ ] [8] [Installer's Code] [499]
[Installer's Code] [499]. All keypads will be busy for the duration
of the PC-Link connection. The status LEDs will display the cur-
rent system status on the keypad where the PC-Link was initi-
ated. For more information on connecting the PC-Link, refer to
your "PC-Link Download Kit Instruction Sheet".
Downloading can also be performed through the LINKS1000 cel-
lular communicator if the telephone line is disconnected. If using
the LINKS1000 with Call Back, you need to program the
LINKS1000 Preamble with the downloading telephone number
in order for the panel to call the computer correctly.
NOTE:When uploading labels from LCD keypads, the DLS
software will receive the labels only from the LCD keypad
assigned to slot 8. In addition, version 1.0 and version 2.0
LCD keypads are not compatible on the same system. For
more information refer to the Download Manual included
with the computer software.

5.10 Telephone Line Monitoring (TLM)

When the TLM Enable option is selected, the panel will super-
vise the telephone line and will indicate a trouble condition if the
telephone line is disconnected.
If the TLM Enable option is ON, the panel will check the tele-
phone line every 10 seconds. If the telephone line voltage is
below 3V for the number of checks programmed in the TLM
Trouble Delay section, the panel will report a TLM trouble. The
default number of checks is 3. Enter a number from (000) to
(255) in the TLM Trouble Delay section to change the number of
checks before the TLM trouble is reported. Programming a delay
means that a momentary interruption of the telephone line will
not cause a trouble condition.
If the TLM Trouble Beeps When Armed option is enabled, the
panel will indicate a TLM trouble at the keypad while the system
is armed. To activate the bell output in the case of a TLM trouble
while the system is armed, the TLM Audible (Bell) When
Armed option must be selected.
When the trouble condition is restored, the panel can send a
TLM Restoral reporting code. Any events which occur while the
telephone line is down will also be communicated.
If the LINKS1000/GSM1000 Cellular Communicator, or
LINKS2X50 is being used, the panel can be programmed to
report a TLM Trouble Reporting Code.

5.11 Test Transmissions

To ensure that the communication link with the central station is
functioning properly, the panel can be programmed to send a
test transmission signal on a regular basis.
The panel can send a Periodic Test Transmission Reporting
Code at the programmed Test Transmission Time of Day. The
Test Transmission Cycle determines the period of time between
tests. The option Land Line Test Transmission in Minutes/
Days allows you to select whether the Land Line Test Transmis-
sion cycle will be counted in minutes or days. If you have selected
the test transmission cycle to be in minutes, the Test Transmission
Time of Day counter will not apply.
NOTE: The LINKS1000/GSM1000 Test Transmission can only
be programmed in days.
The Test Transmission Cycle must be greater than 10 min-
utes. A cycle timer of less than 10 minutes will cause dam-
age to the control panel.
