34 REFERENCE & INSTALLATION MANUAL
10 DIALER OPTIONS
10.1 TELEPHONE LINE MONITORING
SECTION [521]: OPTIONS [1] AND [2]
When enabled, the system verifies the existence of a telephone
line once every second. After each successful test, the dialer LED
(green light) on the control panel flashes briefly. A line test failure
occurs when the TLM detects less than 3 volts for the period
defined by the TLM Fail Timer (see section 10.1.1). If the line test
fails, the dialer LED will flash and will generate one or more
conditions as defined by the TLM settings below, until the control
panel detects the telephone line again. Please note that when the
dialer detects a telephone ring, the TLM test stops for 1 minute.
TLM DISABLED
[1] OFF and [2] OFF
TROUBLE ONLY
[1] ON and [2] OFF
Upon line test failure, the Communicator trouble will appear in the
keypad's Trouble Display.
ALARM IF SYSTEM ARMED
[1] OFF and [2] ON
Upon line test failure, the Communicator trouble will appear in the
keypad's Trouble Display and the control panel will generate an
alarm if the system is armed.
SILENT ALARM BECOMES AUDIBLE
[1] ON and [2] ON
Upon line test failure, the Communicator trouble will appear in the
keypad's Trouble Display and cause a Silent Alarm zone or Silent
panic alarm to switch to an audible alarm.
10.1.1 TLM Fail Timer
SECTION [255]
If the TLM does not detect the existence of a telephone line for the
time programmed in this section, the control panel will generate the
condition(s) defined by the TLM options (see section 10.1). Enter
any value between 016 and 255 (value is X2 seconds) into section
[255]. Entering a value between 000 and 016 will set the TLM Fail
Timer to 32 seconds.
10.2 TONE/PULSE DIALING
SECTION [521]: OPTION [4]
Option [4] ON = the control panel can dial using the tone/DTMF
format.
Option [4] OFF = the control panel will use the pulse dialing format.
Refer to section 10.3 for setting the pulse ratio.
10.3 PULSE RATIO
SECTION [521]: OPTION [5]
When using Pulse dialing (see section 10.2), you can select one of
two Pulse Ratios. Although most European countries use the 1:2
pulse ratio, the 1:1.5 ratio may provide better results in some
cases. The same applies for North American countries. If the 1:1.5
pulse ratio is not providing the desired results, the 1:2 ratio may be
used.
Option [5] ON = North American pulse ratio of 1:1.5
Option [5] OFF = European pulse ratio of 1:2
10.4 BUSY TONE DETECTION
SECTION [521]: OPTION [6]
Option [6] ON = the control panel can immediately hang up if it
receives a busy signal when dialing an outside
number.
Option [6] OFF = feature disabled
10.5 SWITCH TO PULSE
SECTION [521]: OPTION [7]
Option [7] ON = When reporting events to the central station, the
control panel can switch from tone dialing to
pulse dialing on the fifth attempt. The control
panel continues to use pulse dialing until it
establishes communication. If switching to
another central station telephone number, the
control panel will return to tone dialing and will
switch back to pulse dialing on the fifth attempt.
Option [7] OFF = Feature disabled
10.6 BELL ON COMMUNICATION FAIL
SECTION [521]: OPTION [8]
Option [8] ON = If the control panel fails to communicate with the
central station when the system is armed, the
control panel can enable the BELL output, which
will set off any bells or sirens connected to the
output.
Option [8] OFF = Feature disabled
10.7 DIAL TONE DELAY
SECTION [522]: OPTION [7]
Option [7] ON = Dialer will hang up if no dial tone is present after
32 seconds
Option [7] OFF = Dialer will continue to dial if no dial tone is
present after 3 seconds. If more time is required,
you can insert a 4-second pause into the desired
telephone number sequence (see section 9.3).
