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.
