F. System Bypass

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-4

will now ignore all

Touch Tone commands on the next off-hook.

G. Music Mute

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.

H. Outside Line Access Mode (Dial 9)

With DIP switch 

3

in the 

OFF

position (see 

DIP Switch Programming

page 8), simply coming off-hook will instantly give you the

outside line. With DIP switch 

3

in the 

ON

position, you must dial a “

9

” to get an outside line. The 

SLP-4

’s features remain the same

in either mode.

Note:

Instant outside line access mode is for use with private dial tone.

I. Door Chime (Doorbell Switch Input)

With DIP switch 

1

in the 

OFF

position (see 

DIP Switch Programming

, page 8), the doorbell input terminals on the 

SLP-4 

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/message 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

2

in the 

ON

position, the first triggered chime input on the 

SLP-4

can be connected to the 

C-1000B

or 

C-2000A

nor-

mally open auxiliary relay contacts. When a doorbox on the 

C-1000B

, or a door phone on the 

C-2000A

is activated, the 

SLP-4

will

momentarily mute the background music and play the first chime/message sound over the speakers.  When doorbox 2 on the 

C-

1000B

, or door phone 2, 3 or 4 on the 

C-2000A

is activated, the second chime/message will be heard over the speakers. This is

ideal for determining which door the visitor is located at without having to answer the telephone.  

Note: 

The 

C-1000B

or 

C-2000A

must have the auxiliary contact mode programmed for custom ring cadence.  For more information, refer to the 

C-1000B

or 

C-2000A

Technical Practice.

J. Loud Ringing

The 

SLP-4

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.

K. I.O. Communications (for Multi-Line Applications)

The 

SLP-4

is designed to operate on a single phone line. If paging is required on two or more phone lines, connect one 

SLP-4

per

line. Multiple 

SLP-4

’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-4

. 

Caution:

This connection is polarity sensitive. With the I.O. communication con-

nected between each 

SLP-4

, paging will be allowed on a first come, first serve basis. If paging is active on one 

SLP-4

, any person

attempting to page on another 

SLP-4

will hear a busy signal on their phone.

10

E. Phone to Phone Intercom

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 

0

key. Another phone coming off-hook will be instantly connected.
