• BPS Formats - 0 is not valid in Account or Rep Code (A must
be used)
• SIA - This format uses 300 Baud FSK as the communication
media. The Account Code can be 4 or 6 hexadecimal digits in
length, All reporting codes must be 2 digits in length. The SIA
format will transmit a 4 (or 6) digit account code, a 2 digit
identifier code and a 2 digit reporting code. The 2 digit identi-
fier is pre programmed by the panel.
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 Cellular Communicator, or LINKS2X50 is being
used, the panel can be programmed to report a TLM Trouble
Reporting Code.
[351]-[376] - Communicator Call Directions
For events from each Call Direction group the control panel can
call 2 different phone numbers and use the LINKS as backup or
as a redundant communicator for one or both numbers. The
Third phone number can only be used as a backup or alternate
of the first.
Each report falls under one of the following 5 Groups:
1. Partition X Alarms & Restores
2. Partition X Openings & Closings
3. Partition X Tampers & Restores
4. System Maintenance Alarms & Restores
5. System Test Transmissions
Each group can be assigned to the following Call
Directions
1. Option 1 - 1st Telephone Number (and 3rd Telephone Num-
ber if enabled for Alternate or Backup)
2. Option 2 - 2nd Telephone Number
3. Option 3 - 1st Telephone Number Via LINKS (and 3rd Tele-
phone Number if enabled for Alternate or Backup)
4. Option 4 - 2nd Telephone Number Via LINKS
5. Option 5 - Alternate Communicator. This allows the panel to
have control of what types of events the LINKS2X50 products
will communicate. This Call Direction is enabled at default.
