Add Paging to Your Existing Phone Line
Without an Expensive Phone System
Features
The SLP-1 Single Line Paging controller will
allow you to page family members or co-
workers from any phone in your home or
small office. The pages can be heard over
the same speakers that are installed for
multi-zone music distribution.
The SLP-1 connects in series with a single
existing phone line. The unit has a built-in 2
watt amplifier, pre-amp output, music on hold
input, intercom features and selectable loud
ringing. The SLP-1 provides an input for a
lighted doorbell switch, allowing a door chime
to be heard over existing speakers. Page
from several different phone lines by
connecting multiple units.

* Note: Most multi-zone controllers/amplifiers require a 12VDC trigger signal or relay contact closure to automatically switch the source to the “page” input. The SLP-1
will provide a switched 12VDC (20mA maximum) signal or relay contact closure which is maintained while the unit is paging or for the duration of the chime/ding-dong
sound (approximately 2 seconds). The SLP-1 can also provide a secondary “dry” contact page trigger output. N.O. and N.C. relay contacts are available on solder
pads J9 1-3 (see diagram above). Users often turn off all zones when they retire for the evening. In this event, we recommend dedicating up to three 8-Ohm speakers
on the SLP-1’s 2 watt speaker output. They should be placed in central locations (hallways, etc.) on each level so the door chime can be heard when all zones are dis-
abled. Caution: This connection is polarity sensitive.
** Warning: Multi-zone controllers with-
out a page trigger input (audio sensing
only) are not recommended, as the 1st
word during paging is usually omitted.
C. Connecting to the “Page” Input on Multi-Zone Controllers / Amplifiers and Controlling an
Existing Doorchime
Note: The background music mute command (#5), should not be used when connecting multiple SLP-1’s to a
single amplifier, see Operation section K, page 8.
* Note: The internal 2 watt amplifier
should only be used on the last
SLP-1 in the chain.
Caution: I.O. communications
connection is polarity sensitive.

F. Provide Paging, Doorbox, and Doorstrike Control with Unique Front and Back Door Chimes
Note: To provide unique front door bell chime (ding-dong) and back door chime (ding-ding), the C-1000B must be programmed to enable
the “Auxiliary Contact Mode” (
Q 7) and have the auxiliary contact programmed for custom ring cadence (12#03). Doorbox ringing can
also be disabled by placing the C-1000B in the “Doorbell Mode” ( Q 1). See the C-1000B Technical Practice for programming details. The
C-1000B CCTV Video Control Mode can NOT be used in conjunction with unique front and back door chimes. See Operation section I,
page 7. The caller’s music on hold is limited to 5 seconds while communicating with a doorbox.

G. Provide Paging with Four Unique Door Chimes and Control of Up to Four Entry Phones
and Doorstrikes from a Single Phone Line
Note: To provide unique door chimes, the C-2000B must have the “Auxiliary Contact Mode”
enabled (DIP switch 1 OFF) and have the auxiliary contact programmed for “Entry Phone
Triggered Ring Cadence Activation” (3#60). Entry phone ringing can also be disabled (0#62).
See the C-2000B Technical Practice for programming details.The caller’s music on hold is
limited to 5 seconds while communicating with an entry phone.
Door Chimes:
Entry 1 = “ding-dong”
Entry 2 = “ding-ding”
Entry 3 = “ding-ding-ding”
Entry 4 = “ding-ding-ding-ding”
H. Provide Whole House Paging, Control Up to 2 Entry Phones and Doorstrikes and Provide
Entry Phone Triggered Unique Front and Back Door Chimes from a Single Line Phone
The SLP-1 can be used with one or two Viking C-500 entry phone controllers. The phone line first runs through the SLP-1, then runs
through one or two C-500’s before continuing on to the house phones. Connect both C-500’s “SLP Control” output terminals 18 & 19 to
the SLP-1’s “Doorbell Sw Input” input (CAUTION: This connection is polarity sensitive.) When entry phones call in, the SLP-1 will play a
“ding-dong” door chime for an entry phone 1 call and a “ding ding” door chime for an entry phone 2 call, a “ding-ding-ding” chime for an
entry phone 3, and a “ding-ding-ding-ding” chime for an entry phone 4 call. To provide the 4 different door chimes, the SLP-1’s “Doorbell
Mode” DIP switch 2 must be set to ON. The C-500’s entry phone ringing can be disabled by entering 0#62 in programming. See the C-500
Product Manual for complete programming instructions (DOD 177).
* See the C-2000B Product Manual for complete programming instructions (DOD# 156).
Important: With a C-2000B as the controller, the P/N number of the SLP-1 must be 259967F or higher in order for
this application to work. If the controller is a C-2000A, the P/N number of the SLP-1 must be no higher than 259967E.

The SLP-1 can provide on-hold alarm tones to alert you that a caller has been left on hold. After each minute the
call has been left on hold, the SLP-1 will momentarily mute the background music and output a double beep tone
over the speakers. This feature can be disabled by setting DIP switch 1to OFF (see DIP Switch Programming
above).

* Note: This mode will provide unique chimes for each doorbox/entry phone when
used with a C-200, C-500, C-1000B or C-2000B (see Operation section I).
To page throughout the house/small business, simply press #, then 7(the letter “P” key on your keypad). Speak
into the phone receiver and your voice will be heard throughout the house or small business over the speakers.
If background music is present over the speakers, it will automatically mute allowing your page to be heard. If you
have a caller on the phone, they will automatically be put on hold. You can get the caller back by simply pressing
#8 or by momentarily hanging up. Note: The PAGE LED will light during paging.
A. Paging
To place a call on hold, simply press #then 6(the letter “O” key on your keypad), two beeps should be heard
confirming the call is on hold, then hang up. The call can then be taken on another phone elsewhere in your home
or small business. Optional Music-On-Hold can be provided.
B. Placing a Call On Hold
If you hang up the phone after placing a call on hold, simply coming off-hook with any phone will return you to the
caller on hold. If you have placed a caller on hold (#6) or have announced a page (#7) and have remained off-
hook, enter #8 or momentarily hang up to return to the caller on hold.
If the caller hangs up while on hold, the SLP-1 can sense a CPC disconnect signal and will automatically release
the line. Note: The SLP-1 has a maximum on-hold call time of 1 hour. After a caller has been on hold for 1 hour,
the SLP-1 will automatically disconnect the call.
C. Releasing a Call On Hold
D. On-Hold Alarm Tones

This feature allows you to first page someone over the speakers, then speak with them over the phone without
the conversation being heard over the speakers. To perform this function, simply press #, then 7(the “P” key on
your keypad), announce your page, then press the numeric 0key. Another phone coming off-hook will be instantly
connected.
E. Phone to Phone Intercom
The system bypass allows you to use outside phone services (automated attendants, etc.) that require the use of
the #key. Come off hook with any phone and enter #9, two confirmation beeps should be heard, hang up the
phone. The SLP-1 will now ignore all Touch Tone commands on the next off-hook.
F. System Bypass
To mute the background music any time you are on the phone, simply enter #5. The background music will return
when you enter #5 again or hang-up the phone. The MUTE LED will light while the background music is muted.
Note: The music mute command (#5) should not be used in multi-line applications.
G. Music Mute
With DIP switch 3in the OFF position (see DIP Switch Programming page 7), simply coming off-hook will instantly
give you the outside line. With DIP switch 3in the ON position, you must dial a “9” to get an outside line. The
SLP-1’s features remain the same in either mode. Note: Instant outside line access mode is for use with private
dial tone.
H. Outside Line Access Mode
With DIP switch 2in the OFF position (see DIP Switch Programming, page 7), the doorbell input terminals on
the SLP-1 can be connected to a normally open switch (lighted or non-lighted doorbell buttons, etc.). When the
switch is activated, the unit will momentarily mute the background music and provide a door chime (ding-dong)
sound over the speakers. Note: This input is not polarity sensitive and is designed to light standard 6-16V lighted
doorbell switches.
With DIP switch 2in the ON position, the doorbell input terminals on the SLP-1 can be connected to a C-200,
C-500, C-1000B or C-2000B normally open auxiliary relay contacts. When doorbox 1 on the C-1000B (or an entry
phone on a C-200) is activated, the SLP-1 will momentarily mute the background music and provide a door chime
(ding-dong) sound over the speakers. When doorbox 2 on the C-1000B is activated, a double chime (ding-ding)
will be heard over the speakers. When doorphone 1 on the C-2000B or C-500 is activated, the SLP-1 will
momentarily mute the background music and provide a door chime (ding-dong) sound over the speakers. When
door phone 2, 3 or 4 on the C-2000B or C-500 is activated, the SLP-1 will produce 2, 3 or 4 dings respectively.
This is ideal for determining which door the visitor is located at without having to answer the telephone. Note:
The C-1000B or C-2000B must have the auxiliary contact mode programmed for custom ring cadence. For more
information, refer to the C-200, C-500, 1000B or C-2000B Product Manual.
I. Door Chime (Doorbell Switch Input)
The SLP-1 can momentarily mute background music and provide loud ringing (warble sound) over the speakers
each time the incoming phone line rings. To enable this feature, short terminals labeled LOUD RING ENABLE.
This input can also be connected to a SPST switch or time controlled relay for night ring applications. Note: With
loud ringing enabled, if the incoming phone line rings during a page or phone to phone intercom, a short “loud
ring” burst will be heard over the speakers every 15 seconds or until the line stops ringing.
J. Loud Ringing
The SLP-1 is designed to operate on a single phone line. If paging is required on two or more phone lines, connect
one SLP-1 per line. Multiple SLP-1’s can be connected to the same Pre-Amp, Amp or Receiver. In this application
the terminals labeled IO COM should be connected in parallel to each SLP-1. Caution: This connection is polarity
sensitive. With the I.O. communication connected between each SLP-1, paging will be allowed on a first come,
first serve basis. If paging is active on one SLP-1, any person attempting to page on another SLP-1 will hear a
busy signal on their phone.

The C-200 allows single line telephones or a telephone system to share a phone
line with a single Viking entry phone. Tenants may answer an entry phone call and
converse with the visitor.
The C-200 provides a “Call Waiting” tone when the phone line is in use.
Tenants may call out to the entry phone for monitoring purposes. Auxiliary contacts
are provided to operate a doorbell, or activate a camera, lights, etc.
Basic Single Entry Phone Interface
• Add an entry phone to your standard
home or office phones to provide door
communication
• Provide commercial or residential secu-
rity via two-way handsfree communica-
tion at the door or gate
• Connects in series with a single phone
line or to a phone system’s unused line
input (loop start trunk input)
For more information, see DOD 169
Advanced Two Door Entry Phone Controller
with Call Forwarding and Door Strike Controls
The C-500 allows single line telephones or a
telephone system to share a phone line with
two Viking entry phones. Up to four C-500’s
can also be connected in series allowing con-
trol of up to eight entry phones and/or
doorstrikes. Tenants may answer an entry
phone call, converse with the visitor and let
them in with a touch tone command which
activates one of two relays to control a gate
or door strike.
The C-500 also has a built in five number di-
aler to call your cell phone or an outside line
if there is no answer on the inside phone. If
the outside call is busy or ring no answer, the
C-500 can call up to four more numbers.
The C-500 provides the house phones with
user programmable entry phone “Caller ID”.
Tenants may also call the entry phones for
monitoring purposes or enter touch tone
commands to activate, deactivate or toggle
the doorsrike/gate relays.
The C-500 allows up to 6 permanent keyless
entry codes, 2 “one time use” entry codes
and 1 toggle entry code for each door. The
C-500 provides optional entry phone distinc-
tive ring, two trigger inputs for “Request to
Exit” and field programmable Caller ID or
beep tones when answered to indicate which
door is activated.
For more information on the C-500, see DOD 177

Add One or Two Doorboxes to an Existing
Phone Line and Provide CCTV Camera Control
The C-1000B allows single line phones or phone systems to share a phone line with one or
two Viking doorboxes or paging amplifiers. The C-1000B provides two Touch Tone controlled
relays to operate door strikes or gate openers and provides doorbox triggered CCTV cam-
era switching.
Viking doorboxes and paging amplifiers can be used on single line, residential or home office
applications as well as on fully loaded systems, because they are no longer limited to instal-
lation on unused trunk ports.
• Add one or two Viking Doorboxes to your home or
office phones
• Switch between two CCTV cameras automati-
cally when either doorbox is activated
• Add a Viking SLP-1 Single Line Paging Controller
to provide paging, intercom, loud ringing, door
chime and music on hold features
• Provide commercial or residential security via two-
way handsfree communication from a door or gate
• Use as a line concentrator (one fax machine or an-
swering machine can answer three lines)
For more information, see DOD 168
Add Entry Phones and Doorstrike Control to an Existing
Line Or Securely Operate Multiple Doorstrikes
The C-2000B offers two operational modes for
flexibility in operation.
In the Single Line Ring Through Mode, the C-
2000B allows single line phones to share a phone
line with 1 to 4 entry phones. Tenants may con-
verse with visitors and activate a contact closure
to control gates or strikes. The C-2000B provides
entry phone “Caller ID” and “Call Waiting Caller ID”
and a “Call Waiting” tone when the phone line is in
use. Tenants can enter at each location by enter-
ing a keyless entry code.
In the Analog Station Dial Through Mode, the C-
2000B allows 1 to 4 entry phones to share one
analog PABX extension or telephone line and
place outgoing calls. When a remote party an-
swers, they can converse with visitors and activate
a contact closure to control gates or strikes. Mon-
itoring entry phones, forcing doorstrike relays to
operate or remote programming of the C-2000B
can be accomplished by calling the analog PABX
extension or telephone line connected. Authorized
personnel can enter at each location by entering a
keyless entry code.
In either operational mode, the secure relay control
of the C-2000B prevents the entry phone from di-
aling the activation code on the keypad of the entry
phone or using a hand held touch tone dialer. An
auxiliary input is available for connecting a lighted
doorbell switch, a common garage door opener/re-
ceiver or an auxiliary keyless entry keypad.
For more information on the C-2000B, see DOD 156

FCC REQUIREMENTS
This equipment complies with Part 68 of the FCC rules and the requirements adopted by the ACTA.
On the side of this equipment is a label that contains, among other information, a product identifier in
the format US:AAAEQ##TXXXX. If requested, this number must be provided to the telephone com-
pany.
The REN is used to determine the number of devices that may be connected to a telephone line. Ex-
cessive REN's on a telephone line may result in the devices not ringing in response to an incoming
call. In most but not all areas, the sum of the REN's should not exceed five (5.0) To be certain of the
number of devices that may be connected to a line, as determined by the total REN's, contact the
local telephone company. For products approved after July 23, 2001, the REN for this product is part
of the product identifier that has the format US:AAAEQ##TXXXX. The digits represented by ## are
the REN without a decimal point (e.g., 03 is a REN of 0.3). For earlier products, the REN is separately
shown on the label.
The plug used to connect this equipment to the premises wiring and telephone network must comply
with the applicable FCC Part 68 rules and requirements adopted by the ACTA. If your home has spe-
cially wired alarm equipment connected to the telephone line, ensure the installation of this SLP-1
does not disable your alarm equipment. If you have questions about what will disable alarm equipment,
consult your telephone company or a qualified installer.
If the SLP-1 causes harm to the telephone network, the telephone company will notify you in advance
that temporary discontinuance of service may be required. But if advance notice isn't practical, the
telephone company will notify the customer as soon as possible. Also, you will be advised of your right
