Operation
14 025-9567E
To prepare Instant Calls, merely press the desired Instant Call key or keys. Each key, when
pressed, generates a position number that corresponds to one of 206 call stacks. Up to 16
calls may be queued per panel even while one call is being sent. When the key has been
pressed the integral status LED will illuminate indicating that the key number has been
entered into the queue. If an LED does not illuminate when its key is pressed then it may be
because the key was pressed too lightly or because the queue was full. The call stack of the
key will not be sent unless its status LED illuminates.
If the review-before-send option is disabled then sending will begin as soon as the first
Instant Call key is pressed. If the review-before-send option is enabled then transmission of
the queued Instant Calls will occur only when the originating panels SEND QUEUE key
(lower left Instant Call key) is pressed. When the SEND QUEUE key starts a transmission,
its LED will turn on and will stay on until the queue becomes empty. Call stacks that are not
sent because they are unprogrammed will cause the LED to turn off completely and the
encoder to beep. Once an Instant Call begins, any keystrokes entered from the encoder’s
keypad, including the keyboard stack, are lost. However, calls initiated from the keypad
already in progress will not be disturbed. As the Instant Call queue is sent, it is sent in the
order that the keys were pressed (the first key pressed is the first Instant Call sent). The call
stack number (same as Instant Call number) displays briefly as it begins. As the calls in the
call stack are sent, their numbers also are displayed.
If during transmission the encoder begins to beep repeatedly then the channel needed by the
call shown in the display is busy. To force the transmission, press the any Instant Call key
that has its indicator fully on. If the desired channel remains busy for over 30 seconds then
the individual call of the call stack will be skipped over.
After the call stack is sent, the encoder will beep and the LED of the Instant Call key will
begin blinking. Note that the blinking action will also be taken on the LEDs of any parallel
addressed panels as well. Blinking indicators will continue to blink until cleared using the
CLEAR key of the individual panel (lower right key) or the RESET key on the encoder. The
RESET key of the encoder will cause all Instant Call status LEDs on all panels to go out
immediately. The operation of the
CLEAR key depends on the position of the clear key
jumper at the back of the Instant Call panel. In the “all” position the CLEAR key, when
pressed, will cause all of the panels status LEDs to turn off immediately. When this is done
any Instant Call not yet initiated will be canceled. In the “selective” position, the
CLEAR key,
when pressed, will illuminate its LED indicating that the panel is now in the clear mode.
While the encoder is in the clear mode any key pressed on the panel will cause the LED for
that key to turn off. When the
CLEAR key is again pressed its LED will go out indicating that
the panel is no longer in the clear mode.
Instant Call Key Numbering
The Model 25 system allows the connection of up to three full sized Instant Call panels for a
total of 206 individual Instant Call keys. The total panel count, however, is not restricted to
three since two, or more, Auxiliary panels may be configured to operate in parallel (same
panel address).
