• 6 watts of paging power (powers up to (8) 8 ohm
horns/speakers)
• Increased audio fidelity with low noise amplifier
• Interfaces with ringing C.O. lines, Centrex lines, paging
ports, unused phone system trunk inputs, or ringing
analog station ports
• 600 ohm audio output to connect multiple CPA-7B’s for
larger paging applications
• (1) 8 ohm 25AE paging horn included
• Day/night switchable for paging/loud ring
• Ringing/alert tone volume adjustment
• Paging volume adjustment
• Selectable ring trip paging and night bell
• Background music is muted during page*
• 10 pin cage clamp terminal strip for easier wiring
• Provides “Night Bell” warble tone via contact closure
or ringing analog circuit
• Provides page “Alert” tone before paging
• Adjustable ring trip paging time out for auto disconnect
(disable timeout by removing JP1)
• Audio patch cord provided
* Note: A dry contact closure is required to mute back-
ground music when paging from a 600 ohm paging port
(see Installation section D).
The CPA-7B is a cost effective, multi-purpose, tele-
com paging system.
The CPA-7B features a low noise, high fidelity amplifi-
er, providing 6 watts of power for a variety of telecom
paging applications. It can also provide background
music* and night bell/common audible. In addition,
multiple units may be daisy-chained for larger paging
applications.
Compatible with ringing C.O. lines, Centrex lines and
adjustable analog PABX/KSU station ports as well as unused trunk inputs, the CPA-7B
will also interface directly with standard paging ports. For loud ringing, the CPA-7B gen-
erates an adjustable loud warble from a dry contact closure, a ringing C.O. or a ringing
analog PABX/KSU station.
The CPA-7B is easy to install and can eliminate the installation of multiple bells, relays
and paging cards.

If the equipment is causing harm to the telephone network, the telephone company may request that you disconnect the
equipment until the problem is resolved.
Connection to Party Line Service is subject to State Tariffs. Contact the state public utility commission, public service com-
mission or corporation commission for information.
WHEN PROGRAMMING EMERGENCY NUMBERS AND (OR) MAKING TEST CALLS TO EMERGENCY NUMBERS:
Remain on the line and briefly explain to the dispatcher the reason for the call. Perform such activities in the off-peak
hours, such as early morning or late evenings.
It is recommended that the customer install an AC surge arrester in the AC outlet to which this device is connected. This
is to avoid damaging the equipment caused by local lightning strikes and other electrical surges.
PART 15 LIMITATIONS
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part
15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference
when the equipment is operated in a commercial environment. This equipment generates, uses, and can radi-
ate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause
harmful interference in which case the user will be required to correct the interference at his own expense.
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 company.
The REN is used to determine the number of devices that may be connected to a telephone line. Excessive 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 deter-
mined 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 specially wired alarm equipment connected
to the telephone line, ensure the installation of this CPA-7B 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 CPA-7B 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 cus-
tomer as soon as possible. Also, you will be advised of your right to file a complaint with the FCC if you believe it is nec-
essary.
The telephone company may make changes in its facilities, equipment, operations, or procedures that could affect the
operation of the equipment. If this happens, the telephone company will provide advance notice in order for you to make
Step 1. Set the MODE SWITCH to the RING TRIP
position.
Step 2. Adjust the RING TRIP TIME OUT POT as
required (adjustable from approximately 12 -
80 seconds).
Step 3. Plug a C.O. line, Centrex line or analog PABX/
KSU station into the PAGING INPUT PORT.
Step 4. Make a sample page adjusting paging and
alert tone volume.
Step 5. With the night transfer switch off (open), the
CPA-7B will answer and page, then disconnect
on CPC or time out.
Step 6. With the night transfer switch on (closed), the
CPA-7B will broadcast a night bell ring
(electronic warble tone) during each incoming
ring.
Caution: Do NOT connect speakers with a combined
parallel impedance of less than 1 ohm. To power more
speakers, see Installation/Applications section F.

* Note: Some KSU/PABX’s provide a “common audible” con-
tact closure that activates during incoming ring on the phone
system’s line inputs. Night bell (electronic warble tone) will then
be broadcast over the output. Night bell takes precedence over
voice paging.

Step 2. Adjust the RING TRIP TIME OUT POT to
the maximum (fully clockwise) position.
Step 3. Connect terminal 8 to 5 to provide talk battery
on the PAGING INPUT PORT.
Step 4. Connect the unused trunk port to the PAGING
INPUT PORT.
Note: If both paging and loud ringing audible are required, connect
the night transfer switch (optional), the phone system common audible
dry contacts to terminals 5 and 6 and jumper terminal 6to 7as shown.
Caution: Do NOT connect speakers with a combined parallel imped-
ance of less than 1 ohm. To power more speakers, see
Installation/Applications section F.
* Note: Some KSU/PABX’s provide a “common audible” contact clo-
sure that activates during incoming ring on the phone system’s line
inputs. Night bell (electronic warble tone) will then be broadcast over
the output. Voice paging takes precedence over night bell.
Step 1. Set the MODE SWITCH to the TRUNK/
PAGING PORT position.
Step 2. Adjust the RING TRIP TIME OUT POT to
the maximum (fully clockwise) position.
Step 3. Connect the phone system’s paging port to
the PAGING INPUT PORT.
Step 4. Connect the phone system’s dry contacts to
terminals 5and 7. The contact closure will
activate the alert tone for paging and mute the
background music.
Note: If both paging and loud common audible are required, connect the night trans-
fer switch (optional), the phone system’s common audible dry contacts to terminals
5 and 6 and jumper terminal 6 to 9 as shown.
Caution: Do NOT connect speakers with a combined parallel impedance of less
than 1 ohm. To power more speakers, see Installation/Applications section F.
* Note: Some KSU/PABX’s provide a separate “page” contact closure that activates
when a page is in progress. Some KSU/PABX’s provide a “common audible” con-
tact closure that activates during incoming ring on the phone system’s line inputs.
Night bell (electronic warble tone) will then be broadcast over the output. Voice pag-
ing takes precedence over night bell.
