Definitions
Client: A computer or device that makes use of a server. As an example, the client might request a particular file from the server.
DHCP: Dynamic Host Configuration Protocol. In this procedure the network server or router takes note of a client’s MAC address and
assigns an IP address to allow the client to communicate with other devices on the network.
DNS Server: A DNS (Domain Name System) server translates domain names (ie: www.vikingelectronics.com) into an IP address.
Ethernet: Ethernet is the most commonly used LAN technology. An Ethernet Local Area Network typically uses twisted pair wires to
achieve transmission speeds up to 1Gbps.
Host: A computer or device connected to a network.
Host Name: A host name is a label assigned to a device connected to a computer network that is used to identify the device in various
forms of network communication.
Hosts File: A file stored in a computer that lists host names and their corresponding IP addresses with the purpose of mapping addresses
to hosts or vice versa.
Internet: A worldwide system of computer networks running on IP protocol which can be accessed by individual computers or networks.
IP: Internet Protocol is the set of communications conventions that govern the way computers communicate on networks and on the
Internet.
IP Address: This is the address that uniquely identifies a host on a network.
LAN: Local Area Network. A LAN is a network connecting computers and other devices within an office or building.
Lease: The amount of time a DHCP server reserves an address it has assigned. If the address isn’t used by the host for a period of
time, the lease can expire and the address can be assigned to another host.
MAC Address: MAC stands for Media Access Control. A MAC address, also called a hardware address or physical address, is a unique
address assigned to a device at the factory. It resides in the device’s memory and is used by routers to send network traffic to the correct
IP address. You can find the MAC address of your K-1900-8-IP phone printed on a white label on the top surface of the PoE LAN port.
Router: A device that forwards data from one network to another. In order to send information to the right location, routers look at IP
Address, MAC Address and Subnet Mask.
RTP: Real-Time Transport Protocol is an Internet protocol standard that specifies a way for programs to manage the real-time transmission
of multimedia data over either unicast or multicast network services.
Server: A computer or device that fulfills requests from a client. This could involve the server sending a particular file requested by the
client.
Session Initiation Protocol (SIP): Is a signaling communications protocol, widely used for controlling multimedia communication sessions
such as voice and video calls over Internet Protocol (IP) networks. The protocol defines the messages that are sent between endpoints,
which govern establishment, termination and other essential elements of a call.
Static IP Address: A static IP Address has been assigned manually and is permanent until it is manually removed. It is not subject to the
Lease limitations of a Dynamic IP Address assigned by the DHCP Server. The default static IP Address is: 192.168.154.1
Subnet: A portion of a network that shares a common address component. On TCP/IP networks, subnets are defined as all devices
whose IP addresses have the same prefix. For example, all devices with IP addresses that start with 100.100.100. would be part of the
same subnet. Dividing a network into subnets is useful for both security and performance reasons. IP networks are divided using a subnet
mask.
TCP/IP: Transmission Control Protocol/Internet Protocol is the suite of communications protocols used to connect hosts on the Internet.
TCP/IP uses several protocols, the two main ones being TCP and IP. TCP/IP is built into the UNIX operating system and is used by the
Internet, making it the de facto standard for transmitting data over networks.
TISP: Telephone Internet Service Provider
WAN: Wide Area Network. A WAN is a network comprising a large geographical area like a state or country. The largest WAN is the
Internet.
Wireless Access Point (AP): A device that allows wireless devices to connect to a wired network using Wi-Fi, or related standards. The
AP usually connects to a router (via a wired network) as a standalone device, but it can also be an integral component of the router itself.
Wireless Repeater (Wireless Range Extender): takes an existing signal from a wireless router or access point and rebroadcasts it to
create a second network. When two or more hosts have to be connected with one another over the IEEE 802.11 protocol and the distance
is too long for a direct connection to be established, a wireless repeater is used to bridge the gap.

Username, a password is not used. Caller ID can be programmed if needed. Simply call the unit by entering the
programmed “[email protected]...(Static IP address for the unit)”. The static IP address is normally programmed into
a page button on the VoIP telephones.
When registered to a SIP server in the event that registration is lost you can program the unit to re-resolve using the
current SIP server IP address or route pages through an alternate SIP server. With Alternate Server selected enter the
IP address of the alternate SIP server in the field next to the Register Fails drop down box. Note: With an alternate
SIP server IP address programmed, the IP address for the SIP server and alternate SIP server will be limited to 31
characters.
6. Register Fails (Re-Resolve or Alternate Server)
4. Outbound Proxy
If your SIP provider requires an outbound proxy IP address enter it in the Outbnd Proxy field. If outbound proxy is not
required enter the SIP sever IP address into the Outbnd Proxy field. Note: If not required, this field must match your
SIP server IP address.
5. Authentication ID
If your SIP provider requires Authentication ID, enter it in the Authentic. ID field. If Authentication ID is not required,
leave this field blank.
2. SIP Server
1. Unit Name
Up to a 31 character unit name can be assigned to the K-1900-8-IP Series Phone being programmed.
Enter the IP address or URL of your SIP server or service provider in this field. The SIP server IP address is limited to
74 characters. Note: If an alternate SIP server IP address is programmed, the IP address for the SIP server and
alternate SIP server will be limited to 31 characters. Note: If outbound proxy is not required, enter the SIP server IP
address into the Outbnd Proxy field.

7. Phone Number Database
Clicking on the “Phone Number Database” button will open a screen allowing you to program all the Tenants Name’s,
Speed Dial Numbers, and Primary and Roll Over phone numbers. Tenant names are stored locally on the PC and are
not uploaded.
The Speed Dial Number is the 1 to 3 digit (0 - 999) number visitors enter on the K-1900-8-IP Series’s keypad for the
unit to call the tenant. 3 seconds after the 1 to 3 digit number is entered, the unit will then dial the Primary Phone Number
associated with that Speed Dial Number. If there is no answer or a busy signal is detected, the K-1900-8-IP Series
phone will then dial the Roll Over Phone Number.
The Primary Phone Number programmed in Index 0 is the number that is dialed when the handset is lifted and the
visitor does not dial any digits on the keypad before the “off hook dial delay” timer has expired ( if “Off Hook AutoDial”
is enabled). A second Roll Over Number will be dialed when there is no answer or a busy signal is detected. The
K-1900-8-IP Series phone is factory set with no Primary or Roll Over numbers programmed.
Note: Typical Apartment Applications use the tenant’s 1 to 3 digit apartment number as the Speed Dial Number. After
the apartment number is entered the unit will then dial the tenant’s phone number.

13
8. Event Log
The Event Log button is used to open the Event Log screen. The Event Log screen shows you the time and date of
each event, the event type, relay action (which door/gate was opened or closed), entry code index and phone number
index with tenant name. The Event Log can store up to 4,095 events. Events are stored in a first in first out format.
When the memory is full, new events will over write the oldest events. The Event log can be saved in one of two file
formats: Tab Delimited Text or Comma Separated Variable.
9. Entry Code Database
Clicking on the “Entry Code Database” button will open the Entry Code Database screen.
The Entry Code Database will then download. The Entry Code Database will allow you to program the Relay Function,
Relay 1 and/or 2, once only (one time use only), Entry Type (Card, Keyless or both), Keyless Code, Proximity Card #,
Facility Code, Day of week, Time of Day and Tenant Name. Tenant names are stored locally on the PC and are not
uploaded. Note that the same keyless entry code or card number can be programmed multiple times, as shown in the
example below with the “2222” keyless entry code.

14
The security code allows the user/installer to program the K-1900-8-IP Series phone. It is recommended that the factory
set security code be changed. Factory Setting: 845464
Note: The security code must be 6 digits and cannot include a , or a #.
11. Security Code
The access code comes into play when a tenant calls the K-1900-8-IP Series phone and a visitor lifts the handset to
answer the call or the K-1900-8-IP Series phone automatically answers the call (see Inbound Call Mode). It is a 1 to
6 digit code (can not contain “,” or “#”) that the tenant must dial before they are allowed to operate the door strike
relays, as extra security on inbound calls. Once a tenant has entered the correct access code, 2 beeps are heard and
the user can now enter any “Remote Access Operation Commands” (see page 22). The access code can be disabled
if this basic security is not required. Factory Setting: 123456
12. Access Code
Keyless Entry Code and Proximity Card logging can be set to Log Errors. With Log Errors selected, the K-1900-8-IP
Series phone will not only log all valid Keyless Entry Code and Proximity Card entries, but also log any errors, incorrect
codes, or non-valid card reads.
Keyless Entry Code and Proximity Card logging can also be set to Live Logging. With Live logging selected and the
K-1900-8-IP Series programming software open and connected to a unit, each Keyless Entry Code entered or Proximity
Card read will immediately open the Event Log screen.
10. Keyless/Card Logging
13. Wiegand Direction
Wiegand Direction allows you to decide if the 26 bit Wiegand connection will be used as an input or an output. The default
setting for direction is “Inbound” and this is the correct setting if you intend to connect a card reader or Wiegand keypad
device to the wiegand connections.
When the direction is set to “outbound”, the 26 bit Wiegand connections become an output and can be connected to the
card reader input on the access control system. Unprogrammed keyless entry codes dialed by the user on the keypad are
then sent over the Wiegand output. When the user dials “#” plus a entry code that is not programmed in the Entry Code
Database, the code dialed by the user is sent over the Weigand output along with the facility code selected. Since Wiegand
data limits the entry code to 65535 maximum, “#” plus entry codes higher than 65535 are not sent over the Wiegand
output. When the user dials “#” plus a valid keyless entry code that is programmed in the Entry Code Database, the code
dialed by the user is not sent over the Wiegand output and the Local / External relay is activated.
When using date and time logged events or setting the access date and times of keyless codes or proximity cards in
the Entry Code Database, you must program the unit to your time zone. Example: You are installing the K-1900-8-IP
Series phone in the Central standard time zone: Select (UTC - 06:00) CST, which is 6 hours behind Coordinated
Universal Time (UTC). Factory Setting: CST
The Daylight Savings Time programming can be enabled or disabled and can be programmed to start on any Sunday
in March and stopped on any Sunday in November. Currently, daylight saving time starts on the second Sunday in
March and ends on the first Sunday in November, with the time changes taking place at 2:00AM local time.
Factory Setting: Enabled

16. Relay 1 or 2 Internal / External
With relay 1 and/or 2 set to “Internal” the K-1900-8-IP Series phone will activate its on board relays for door strike /
gate control. Relay 1 and/or 2 should be set to “External” for higher security installations when using a Viking remote
model RC-4A relay controller to activate the door strike / gate controller (see page 22). Note: With relays set to external
the internal on board relays will also activate at the same time as the external relays. Factory Setting: Internal
Doorstrike Mode (Factory Setting): When programmed for Doorstrike Mode the relay is intended for door strike,
maglock or gate control. The relay can also be touch tone activated by dialing a “#” plus a valid keyless entry code or
by scanning a valid proximity card that has been assigned to that relay.
Outbound Call Mode: When programmed for Outbound Call Mode the relay will activate continuously for the duration
of any outbound call from the Entry phone.
Inbound/Outbound Call Mode: When programmed for Inbound/Outbound Call Mode the relay will activate
continuously for the duration of any inbound or outbound call to or from the Entry phone. This mode is useful for turning
on IR flood lights, for VoIP phones with cameras, etc.
Doorbell Mode: When programmed for Doorbell Mode the relay will momentarily activate the relay for the
preprogrammed relay activation time on any outbound call from the Entry phone. This mode is useful for activating a
door chime, etc. When activating door chimes, a 0.5 - 1 second relay activation time is recommended.
Alarm Mode: When programmed in Alarm Mode the relay will activate continuously while the Entry phone is powered
and registered to the SIP server. In the event the unit loses power and/or SIP registration the relay will turn off, which
can be used to signal an alarm device. This can only be used for internal relay control.
Ring Mode: When programmed for Ring Mode the relay will continuously activate while the ringing extension is called.
This mode is useful for activating a Viking model SL-2 strobe light, etc.
Ring Flash Mode: When programmed for Ring Flash Mode the relay will momentarily turn on and off in a 400ms
on/off cadence while the ringing extension is called. This mode is useful for activating a Viking LPL-1 Remote Visual
Indicator, etc.
17. Relay Mode

16
20. Relay Activation Delay
A relay activation delay of 0.5 - 99 seconds can be programmed in the K-1900-8-IP Series phone. A relay activation
delay is useful in two door vestibule entrance applications. This allows you to program a delay time from when relay 1
(outside door) is activated to when relay 2 (inside door) is activated. The programmed delay time should be set to the
average time it takes a person to walk from the outside door to the inside door.
When a request for exit (REX) is activated, relay 2 will activate first, then after the programmed delay relay 1 will
activate. Factory Setting: Disabled
The value stored in the Relay 1 or 2 Activation Time is the amount of time relay 1 or 2 will be energized after a correct
momentary touch tone command is entered, “#” plus a valid keyless entry code or a proximity card was scanned that
is programmed to momentarily activate the relay. This number can range from 0.5 to 99 seconds. Note: This also
affects timing in Doorbell Mode. Factory Setting: 5 seconds
19. Relay 1 or 2 Activation Time
The one or two digit code stored in the Relay Activation Command is the touch tone command that the person being
called must enter on their phone in order to momentarily activate relay 1 or 2 to control a doorstrike, mag-lock, gate
controller, or other device. The code can contain the characters 0 - 9, 00 - 99, ## or ,,. The code cannot match a
relay latching or toggle command (11, 10, 1#, 21, 20, or 2#). The code must be entered while the remote phone is
communicating with the Entry phone. The Entry phone determines which direction the touch tone is coming from and
only responds to touch tones from the called phone. Factory Setting: Relay 1 - ,,, Relay 2 - ,2
18. Relay 1 or 2 Act (Activation) Command
21. Relay Latch Commands
When set to “Enabled” the Remote Access Operation Commands to Un-Latch, Latch or Toggle the relay are enabled.
When set to “Disable” the Remote Access Operation Commands to Un-Latch, Latch or Toggle the relay are disabled.
Disabling the Latch commands can be useful in applications where you want to eliminate the possibility of inadvertently
entering a latch command leaving a gate open/closed, etc. The relays can still be activated with the “Relay Activation
Command” for momentary closures. Factory Setting: Enabled
25. Phone Mode
The Phone Mode can be programmed to one of two settings: Auto Dialer or Manual Dial Phone. When set to Auto
Dialer the K-1900-8-IP will auto dial any preprogrammed phone numbers stored in the Phone Number Database when
the corresponding Speed Dial Number (example: apartment number) is entered on the unit’s keypad. When set to
Manual Dial Phone the unit’s auto dialing features are disabled and the unit functions as a standard VoIP phone. When
the handset of the K-1900-8-IP is lifted, dial tone is provided and the user can manually dial the desired number on the
keypad. Keyless entry codes can be used in either mode. Factory Setting: Auto Dialer
The In-Band Audio Call Progress Detection can be set to enabled or disabled. In-Band Audio Call Progress detection
should be enabled in applications where you are making an outbound call through your VoIP phone system and are
relying on In-Band analog audio for ringback or busy detection. Factory Setting: Enabled
22. In-Band Audio Call Progress
The In-Band Audio Detect level (Sensitivity) can be set from 1 - 9, 1 = minimum setting, 9 = highest setting. Increasing
or decreasing the sensitivity may be required in applications where you are making an outbound call through your VoIP
phone system and are relying on In-Band analog audio detection. Power cycle unit after changing this setting.
Factory Setting: 5
23. In-Band Audio Detect Sensitivity
The Handset Default Volume can be set from 1 to 4, 1 = lowest volume setting, 4 = highest volume setting. This will be the
default volume setting from off hook but then can be increased or decreased with the handset volume control button. Setting
it to “1, 2, 3, or 4 only” will lock the volume at that setting for all calls (handset volume control button disabled). Setting it to
“last used” will leave the handset volume set to the last user adjusted volume setting.
Factory Setting: 1
24. Handset Default Volume

17
28. Ring Cadence
When “Inbound Call Mode” on the K-1900-8-IP Series phone is set to “Ring Low” or “Ring High” the Ring cadence can
be programmed to one of 4 different cadences: Factory Setting: Normal Ring
Normal Ring (single ring, 2 seconds on 4 seconds off) factory setting
Double Ring (double ring, 1 second on 0.5 seconds off 1 second on 3.5 seconds off)
Short-Short-Long (triple ring, 0.5 seconds on 0.5 seconds off 0.5 seconds on 0.5 seconds off 1 second on 3 seconds off)
Short-Long-Short (triple ring, 0.5 seconds on 0.5 seconds off 1 second on 0.5 seconds off 0.5 seconds on 3 seconds off)
The Inbound Call Mode determines how the K-1900-8-IP handles incoming SIP calls. One option is to generate a ring
sound through the handset receiver, allowing someone to lift the handset to answer the inbound SIP call. The
K-1900-8-IP Series phone can also auto answer the call, to allow remote control of the doorstrike relays and the ability
to listen to transmit audio from the handset of the phone. The last option is the silent monitor mode, which allows
callers to listen to the transmit audio from the handset of the phone at a much higher volume than normal. The “secure”
options for auto answer and silent monitor require the callers to dial the access code in order to remain connected and
listen to the audio from the handset. Factory Setting: Auto Answer
Disabled – Inbound calls are not allowed.
Auto Answer – Inbound calls are auto answered and the caller hears transmit audio from the handset at a normal
volume level.
Auto Answer Secure – Inbound calls are auto answered and the caller must dial the access code in order to listen to
transmit audio from the handset (volume level is still normal).
Ring Low – In the “low” mode the phone will output a ring signal out of the earpiece in the ring pattern selected in
Ring Cadence. The call can then be answered by taking the handset off hook.
Ring High – In the “High” mode the phone will output a slightly louder, higher pitched ring signal out of the earpiece
in the ring pattern selected in Ring Cadence. The call can then be answered by taking the handset off hook.
Silent Monitor – Inbound calls are auto answered and the caller hears transmit audio from the handset at a much
higher volume level.
Silent Monitor Secure – Inbound calls are auto answered and the caller must dial the access code in order to listen
to transmit audio from the handset (volume level is still at a much higher volume level).
27. Inbound Call Mode
26. 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-1900-8-IP Series phone must rely on a call ended
signal, busy signal, or a touch tone # command to hang-up. Factory Setting: 3 minutes
Note: Timer starts after call is connected. If call is not answered (and ring no answer disabled) there is a default 7 minute
timer.
If enabled and a busy is detected, the K-1900-8-IP Series phone will dial the “Roll Over” speed dial number.
Factory Setting: Enabled
Notes: If the busy signal is interrupted with a promotional message, contact your central office to have it removed.
30. Dial Next Number on Busy
29. Dial Next Number on Ring No Answer
If enabled and a ring-no-answer is detected, the K-1900-8-IP Series phone will dial the “Roll Over” speed dial number
after the programmed amount of rings. This can be set from 1 - 9 rings. Factory Setting: 7 (will redial after 7 rings)

18
33. Off Hook AutoDial
When the Off Hook AutoDial feature is enabled, it allows visitors that do not know the tenant’s apartment number
(Speed Dial Number) a way of simply going off-hook with the handset (with no additional numbers entered) and the
unit will automatically dial the Primary Phone Number stored in Phone Number Database Index 0. This could route the
call to the building manager, care taker, receptionist, etc. The Phone Mode must be set to “Auto Dialer” in order to use
this feature. When the Off Hook AutoDial feature is disabled, a user hears three beeps instead of being routed to Phone
Number Database Index 0, once the Off Hook Dialing Delay has expired. Factory Setting: Enabled
31. In Call Dialing Format
The In Call Dialing Format can be set to In-Band DTMF (Touch Tones) or RFC 2833 (Out of Band DTMF Touch Tones). In
Call dialing refers to the numbers dialed after an outbound call has been answered by the distant party. This would typically
be the numbers dialed to steer through automated attendants, voice mail, etc. If your VoIP phone system does not
automatically convert out of band DTMF to In-Band after the call is answered, set In Call Dialing Format to “Inband DTMF”.
Factory Setting: RFC 2833
32. Off Hook Dialing Delay
The Off Hook Dialing Delay is the length of time a user hears simulated dial tone after picking up the handset before
they are routed to the Primary phone number in the Phone Number Database Index 0 or hear 3 beeps, depending on
the Off Hook AutoDial program option.The time is programmable from 0 to 20 seconds. Off Hook Dialing Delay time is
needed to allow visitors time after they come off-hook to then enter the tenant’s apartment number (Speed Dial Number)
or their Keyless Entry Code. Factory Setting: 3 seconds
34. Mute Current / Next Alarm
A network failure alarm will be indicated by providing 3 beeps every 30 seconds in the handset of the K-1900-8-IP
Series phone. A network failure indicates the unit is not registered to the SIP server or there is a communication failure
with the gateway. The three beeps can be muted by clicking on “Mute Current / Next Alarm”. The Status LED will
continue to flash to assist troubleshooting. The alarm beeps can also be permanently disabled. See Permanent Alarm
Mute.

19
42. REX Input
The K-1900-8-IP has one Request for Exit (REX) trigger input. The REX switch must have a momentary, normally
open contact. When the K-1900-8-IP Series phone 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 17):
NOTE: For security reasons the REX input is only enabled when the relay is set to “Internal”.
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.
35. Permanent Alarm Mute
Selecting “Alarm Tones Disabled” will mute all alarm tones indefinitely. To re-enable alarm tones select “Alarm Tones
Enabled”. Factory Setting: Alarm Tones Enabled
36. IP Firmware
If new K-1900-8-IP firmware is available, after opening the programming software a pop window will come up asking
you if you would like to update firmware. An alternative method of updating can be done by clicking the IP firmware
“Update IP” button. You can then browse to the folder that contains the PIP file for updating the unit’s IP firmware. This
method is typically only used when Viking Technical Support has sent you updated IP firmware.
The Import/Export feature is useful for backing up all the K-1900-8-IP Series phone’s programming or for importing
programming when installing multiple units with a majority of the same programming.
37. Unit Firmware
If new K-1900-8-IP firmware is available, after opening the programming software a pop window will come up asking
you if you would like to update firmware. An alternative method of updating can be done by clicking the Unit firmware
“Update Unit” button. You can then browse to the folder that contains the HEX file for updating the unit’s firmware. This
method is typically only used when Viking Technical Support has sent you updated firmware.
Note: Export your phone settings before updating firmware.

current relay status, or to display information on the last card or fob detected by the card reader.

20
The K-1900-8-IP Series phone can be programmed to function as a single number auto dialer, a multi-number dialer
or a manual dial phone. The operation for the user depends on which mode it is running.
Single Number Auto Dialer (Phone Mode set to “AutoDialer” and the Off Hook AutoDial set to “enabled”)
With the Off Hook Dialing Delay set to “No Delay”, when the handset is taken off-hook, the K-1900-8-IP Series phone will immediately
dial the primary phone number programmed in the Phone Number Database Index 0. If there is no number programmed in the Phone
Number Database Index 0 position, the user will get a simulated busy signal when the handset is lifted. “#” plus a keyless entry code
can be dialed while the handset is hung up. Proximity cards can be scanned at any time, even while a call is in progress. The Off
Hook Dialing Delay can be set to a delay of 1 - 20 seconds in this mode, if you wish to allow users to pick up the handset and dial “#”
plus a valid keyless entry code, instead of being sent to the phone number in the Phone Number Database Index 0.
Multi-Number Auto Dialer (Phone Mode set to “AutoDialer” and a delay time selected for Off Hook Dialing Delay)
With the Off Hook Dialing Delay set from 1 - 20 seconds, when the handset is taken off-hook, the user will hear 1 - 20 seconds of
dial tone, allowing them time to enter the 1-3 digit Speed Dial number (0 - 999). The unit will then dial the Primary Phone Number
associated with the selected 1-3 digit Speed Dial Number (0 - 999). In the event the line is busy or ring-no-answer, the unit can be
programmed to call a second roll over number. If Off Hook AutoDial is enabled, users that don’t dial digits on the keypad during the
provided dial tone will be automatically sent to the phone number programmed into Phone Number Database Index 0. If Off Hook
AutoDial is disabled, users that don’t dial digits on the keypad will hear 3 beeps after the provided dial tone. “#” plus a keyless entry
code can be entered while the handset is hung up, or as the first digits dialed after lifting the handset. Proximity cards can be scanned
at any time, even while a call is in progress. A user that dials “*” on the keypad will automatically be sent to the phone number
programmed into Phone Number Database Index 0.
Manual Dial Phone (Phone Mode set to ”Manual Dial Phone”)
When the handset is lifted in the Manual Dial Phone mode, the user hears dial tone. Any keypad entries dialed by the user are
gathered and sent to the SIP phone system, just like a standard VoIP phone. Proximity cards can be scanned at any time, even
while a call is in progress.
In any of the above modes, relay activation commands can be entered or “#” can be dialed (from the remote phone only) to force
the phone to hang-up.
After communication is established, enter the 1 or 2 digit relay activation command (factory set to “,,” for Relay 1 and ”,2” for
Relay 2) to momentarily activate the entry phone (door strike) relay. Two beeps will be heard confirming that the 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.
*Note: Relay latch Commands can be disabled in programming.
B. Inbound Calls
How inbound calls are handled is determined by the Inbound Call Mode and these are the available options (see Inbound Call Mode
on page 17 for more details):
Disabled - Inbound calls are blocked. Users will get busy or reorder tone if they attempt to call.
Ring Low or Ring High – Inbound calls generate a ring through the receiver of the handset using either a low or high pitched ring
sound. Someone must lift the handset to answer the call.
Auto Answer or Auto Answer Secure – The K-1900-8-IP Series phone auto answers the inbound call and the caller can listen to
transmit audio from the handset at a normal volume level or remotely control the door strike relays if desired. In the “Secure” mode,
the caller must dial the access code in order to listen to handset audio or control relays.
Silent Monitor or Silent Monitor Secure – The K-1900-8-IP Series phone auto answers the inbound call and the caller can listen
to transmit audio from the handset at a much louder volume than normal or remotely control the door strike relays if desired. The
louder volume allows the caller to listen to sounds or conversations occurring around the phone. In the “Secure” mode, the caller
must dial the access code in order to listen to handset audio or control relays.
