2.3.15 Telephone
Line
Monitoring
(TLM)
When the TLM Enable option is selected, the system will supervise the telephone
line and will indicate a trouble condition if the telephone line is disconnected.
If the TLM Enable option is ON, the system will check the telephone line every 10
seconds. If the telephone line voltage is below 3V for the number of checks pro-
grammed in the TLM Trouble Delay section, the system 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 tele-
phone line will not cause a trouble condition.
If the TLM Trouble Beeps When Armed option is enabled, the system will indi-
cate 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 system can send a TLM Restoral
reporting code. Any events which occur while the telephone line is down will also
be communicated.

2.3.16 Test
Transmissions
To ensure that the communication link with the central station is functioning properly,
the system can be programmed to send a test transmission signal on a regular basis.
The system can send a Periodic Test Transmission Reporting Code at the pro-
grammed Test Transmission Time of Day. The Test Transmission Cycle deter-
mines the period of time between tests. The option Land Line Test Transmission
in Minutes/Days allows you to select whether the Land Line Test Transmission
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 Test Transmission Cycle must be greater than 10 minutes. A
cycle timer of less than 10 minutes will cause damage to the system.
When the test transmission cycle is programmed, the system will send a test trans-
mission the following day. This will indicate the beginning of the new test transmis-
sion cycle to central station.
The end user can also generate a communicator test. If the System Test Report-
ing Code is programmed, the system will send the signal when the System Test
keypad command is entered (see [*] [6] User Functions on page 29).
