EXTERNAL PAGING
Installing External Paging (Figure 4-1)
The CPU provides an External Paging output. You connect the
CPU Paging output to audio inputs on customer provided
Paging systems.To connect an External Paging amplifier:
1. Find an available connector in a station cable and make sure
it is correctly punched down at the 66M1-50 block.
Follow standard color code order. Be sure the block is
properly cross-connected.
2. For the connector chosen, locate pins 1T and 1R (see Figure
4-1) and connect the music source.
3. Plug the modular jack into the CPU modular connector.
Be sure the connected Paging equipment is compatible with the
following CPU page output specifications:
Output Impedance: 600 Ohms
Output Level: 0 dBr @ 1.0 kHz

DOOR BOX
Installing the Digital Door Box (Figure 4-2)
The Digital Door Box (P/N 80560) is a self-contained Intercom
unit typically used to monitor an entrance door. A visitor at the
door can press the Door Box call button (like a door bell). The
Door Box then sends chime tones to all extensions programmed
to receive chimes. To answer the chime, the called extension
user just lifts the handset. This lets the extension user talk to the
visitor at the Door Box. The Door Box is convenient to have at
a delivery entrance, for example. It is not necessary to have
company personnel monitor the delivery entrance; they just
answer the Door Box chimes instead.
The number of Door Boxes you can install is limited by the
System Load Factor. (see page 1-16).
The Door Box is a weather-tight unit, with an operating temper-
ature range of 0 to 45 degrees C (32 to 113 degrees F) and a
relative humidity of 10-95%, non-condensing. It is not intended
for outdoor installation.
Any available 16DSTU PCB port can support a Digital Door Box.
To install the Digital Door Box:
1. Snap open the Door Box case.
2. Punch down one end of a two-pair twisted station cable on
the extension block as shown in Figure 4-2.
3. Run the station cable through the hole in the back of the
Door Box.
When wall mounting, use the two holes in the base of
the Door Box for the mounting screws.
4. Strip the conductors back about 1/2 inch and connect to the
Door Box terminals.
5. Snap the Door Box cover back onto the base.
Also see Programming the Door Boxon page 4-6 and
Operating the Door Boxon page 4-7.

DOOR BOX
Programming the Digital Door Box
Door Box Setup 
You must assign the circuit type and chime pattern to each
installed Door Box.
In 1801: Extension Circuit Type, enter 10 to assign the
extension as a Door Box.

In 1801: Door Chime, enter the Door Chime type.
0 = Normal Ring Group ringing.
1 = Low pitch chime pattern.
2 = Mid range pitch chime pattern.
3 = High pitch chime pattern.
If you enter Door Chime type 0 (normal ring) above,
you can set up Call Coverage keys for the Ring Group.
This allows extensions that are not members of the Ring
Group to answer Door Box calls. Extensions with Call
Coverage keys to the Door Box Ring Group can also
activate the relay (see Door Box Relay Control below).
Door Box Ringing 
When a visitor at the door presses the Door Box call button, the
Door Box with alert (chime) all the extensions in the Ring
Group to which the Door Box belongs. For example, if theDoor Box and extensions 301 and 302 are in Ring Group 1,
pressing the call button alerts 301 and 302.

In 1802: Ring Group Number, assign the Door Box and
the extensions that should alert to the same Ring Group.

In 0511: Ring Group Master Extension Numbers and
Names, assign a Ring Group master number to the Ring
Group assigned in the previous step.
Door Box Relay Control 
If the relay on the CPRU controls the strike for the door, the
keyset that answers the Door Box chimes can remotely open
and close the strike. Refer to Connecting to the CPRU Relays
on page 4-8 for more on setting up this option.

In 1801: Relay Owner, enter 1 to assign the CPRU PCB
relay to the Door Box (see Operating the Door Box below).
Enter 0 to disable the CPRU PCB relay for Door Box calls.

In 0401: Door Unlock Time, enter the interval that the
CPRU relay should remain closed after the keyset user acti-
vates (closes) the relay. After this interval, the CPRU auto-
matically returns to its idle (open) state.

DOOR BOX
Operating the Door Box
To place a call from the Door Box:
1. Press the Door Box call button.
2. When someone inside the building answers your call, speak
toward the Door Box.
To place a call to the Door Box:
1. Lift handset and press 
ICM
.
2. Dial the Door Box extension number.
To answer the Door Box chimes from a keyset:
1. Lift handset or press 
SPK
.To control the CPRU relay which in turn controls the
door strike:
Once set up in programming, this option is available
to any member of the Door Box Ring Group as well as
any extension with a Call Coverage Key for the Door
Box Ring Group.
1. To open the relay, press 
FLASH
key or 
OPEN
soft key.
2. To close the relay, press 
FLASH
key again or 
CLOSE
soft key.

CPRU RELAYS
Connecting to the CPRU Relays (Figure 4-3)
Any keyset extension that receives Door Box chimes can con-
trol the CPRU relay, which in turn typically enables an electric
strike on an entrance door next to a Door Box. After answering
the Door Box chimes, the extension user can press a FLASH or
a soft key to enable the associated relay. The visitor at the door
can then enter without having an employee open the entrance
for them.To connect to the CPRU Relays:
1. Find an available connector in a station cable and make sure
it is correctly punched down at the 66M1-50 block.
Follow standard color code order. Be sure the block is
properly cross-connected.
2. For the connector chosen, locate pins 3T and 3R (see Figure
4-3) and connect to the device the relays will control.
3. Plug the modular jack into the CPU modular connector.Be sure the equipment connected to the relays is compatible
with the following CPU relay specifications:
Contact Configuration  . .Normally open
Maximum Load  . . . . . . .60 mA @ 30 VDC
10 mA @ 90 VDC
Maximum Initial Contact Resistance  . .50 mOhms
