(if it is allowed) or direct to the ready mode. See the schematic of
changing the dialer modes.

BLOCKING MODE

The blocking mode, if allowed in the configuration procedure,
enables a use of the dialer as a double line alarm panel. In the
blocking mode the dialer ignores the alarm condition in the lines A
and B. However, if such a condition occurs, the dialer displays the
name of the line in which the alarm was initiated. You switch to the
blocking mode (if it is allowed) from the alarm mode, pause mode
or ready mode by entering the user code or by going to the
programming mode (see the schematic of changing the dialer
modes).

READY MODE

In this mode the program monitors the alarm inputs. When an
alarm is recognized in an alarm line, the system starts counting of
the time delay for the specific line and then it goes to the alarm
mode. Each time the ready mode is activated, which is performed
after entering the user code, it is preceded by performing the
system testing procedure and counting the output delay. When the
blocking line C is released in the ready mode, the alarm inputs A
and B are blocked. The lines A and B remain blocked as long as
the line C remains released. The release condition of the blocking
line C is signalized by displaying the letter C on the dialer display.

ALARM MODE

Single message dialer.

After recognition of the alarm condition in the line A (B), the dialer
begins counting the A (B) input delay. If you do not enter the
correct user or installer code during the counting of the input delay,
the dialer will start dialing the numbers in the list L1..L10, in the
sequence the numbers were put in the list. After making the
connection, the dialer transmits the alarm tone and announcement
five times, then it goes to the next number. The described action is
repeated twice. During the alarm action any signals in the alarm
inputs A and B are ignored.

Double message dialer

In this case the alarm mode initialization algorithm is identical as
for the single message dialer. The difference is that if an alarm
was activated in the input A, the system dials the numbers from
the list A1..A5 and the announcement A is transmitted. If an alarm
was activated in the line B, the system dials the numbers from the
list B1..B5 and the announcement B is transmitted. During the
alarm action the dialer displays two letters informing about the type
of the current alarm action and the name of the alarm input, which
initiated the alarm, to the right from the caption Ready.

Alarm types:
AG – loud alarm

(activates the PGM output)

AC – silent alarm

(does not activate the PGM output)

AN – duress alarm

(silent alarm in the line A)

DURESS ALARM

You can initiate the duress alarm in the Blocking or Ready mode
by entering the duress code:
[*] digit [*]
Regardless the line A programming as silent or loud, or the dialer
configuration as single message or double message, the duress
alarm is performed silently and corresponds the alarm initialization
in the line A. Following the completion of the duress alarm, the
dialer goes direct to the Ready mode.

PAUSE MODE

Single message dialer

When the notification procedure is completed, the dialer switches
to the pause during which it blocks both alarm inputs. After the
pause time has elapsed, the system returns to the ready mode and
stops blocking both alarm inputs.

Double message dialer

When the notification procedure is completed, the dialer switches
to the pause during which it blocks the alarm input from which the
alarm was initiated, monitors the other alarm input and is ready to
start the alarm action from the line, provided it is initiated. During
the notification action both alarm inputs are blocked. After the
pause time has elapsed, the system returns to the ready mode and
stops blocking both alarm inputs.

TELEPHONE LINE LISTENING

Using the headphone output, in addition to listening to the alarm
announcement, you can listen to the notifications, since the
telephone line tones are retransmitted to the headphone output.

EXTERNAL CALL ANSWERING FUNCTION

The function allows you to obtain remote information if there was
an alarm activated at the facility where the dialer is installed. You
can get such information by dialing the dialer telephone number. In
this function the dialer, being in the ready mode, after recognition
of 8 call tones, connects into the telephone line and transmits an
acoustic signal for 20s. If no alarm occurred at the facility from the
time the dialer went to the ready mode, the transmitted acoustic
signal is a two-second acoustic tone, repeated cyclically. If there
was an alarm at the facility, which was not reset, the dialer
transmits a signal, which is modulated in the identical way as the
signal preceding the alarm announcement.
