Operation - Viking K-1275-IP Series Product Manual

29. Call Length Time Out
This feature selects the maximum length of time that calls can be connected. Programmable in increments of 1 minute
up to a maximum of 9 minutes or disabled. With the call length disabled, the K-1275-IP phone must rely on a call ended
signal, busy signal, Ring No Answer limit, or touch tone "#" command to hang-up.
Note: The factory default is 3 minutes.
30. Dial Next Number on RNA (Ring No Answer)
If enabled and a ring-no-answer is detected, the K-1275-IP phone will dial the "Roll Over" speed dial number.
Note: Factory set to redial if not answered after 7 rings.
31. Dial Next Number on Busy
If enabled and a busy is detected, the K-1275-IP phone will dial the "Roll Over" speed dial number. Notes: This feature
is enabled in the factory default setting. If the busy signal is interrupted with a promotional message, contact your
central office to have it removed.
32. REX Input
The K-1275-IP has one Request for Exit (REX) trigger input. The REX switch must have a momentary, normally open
contact. When the K-1275-IP detects a contact closure on the REX trigger input it performs one of the following actions,
based on the Relay Mode settings for each relay (see section 22):
Relay 1 "Door Strike", relay 2 other: Relay 1 will be activated for the programmed Relay 1 Activation Time.
Relay 1 other, relay 2 "Door Strike": Relay 2 will be activated for the programmed Relay 2 Activation Time.
Relay 1 "Door Strike", relay 2 "Door Strike": If the Relay Activation Delay is disabled, Relay 2 will be activated for
the programmed Relay 2 Activation Time. If Relay Activation Delay is not disabled, Relay 2 will be activated for the
programmed Relay 2 Activation Time, then after the Relay Activation Delay time has passed, Relay 1 will be activated
for the programmed Relay 1 Activation Time. This is useful in two door vestibule applications where Relay 1 is used to
unlock the outside door, and Relay 2 is used to unlock the inside door.
NOTE: For security reasons this input is disabled when the relay is set to "External".
A. Keypad
When a Keypad button is pressed, the K-1275-IP immediately dials the pre-programmed telephone number stored in
the corresponding Phone Number Database Index location (1-#). The Call Status LED momentarily flashes during
dialing. In the event the line is busy or there is a ring-no-answer, the unit can be programmed to call a second roll over
number.
When the call is answered, relay activation commands can be entered or the # key can be used to force the phone to
hang-up.
After communication is established, enter the 1 or 2 digit relay activation command (factory set to "QQ"
) to momentarily activate the entry phone (door strike) relay. Two beeps will be heard confirming that the
"Q2" for Relay 2
relay has been activated. If you require the relay to remain on continuously (ie: a truck delivery), enter Touch Tones
"11" or "21" to continuously activate relay 1 or relay 2 respectively. A double beep will indicate that the relay is latched
on. When the visitor calls in again (ie: they are finished unloading the truck), enter Touch Tones "10" or "20" to deactivate
relay 1 or relay 2 respectively. A single beep will indicate the relay is latched off. The relays can be toggled by entering
"1#" and "2#" for relays 1 and 2.
