Remote annunciation – either audible, or
visual, or both – can be triggered by the
CP-220A whenever its own internal
sounder is activated. A typical application
of this process is shown at the right.
FIGURE 1-7
These terminals are typically wired to close a circuit
between a remote power source and the annunciating
device. Refer to Figure 1-7 for details.
Printer (No. 132A Cable)
This connector (or
port
) feeds data to a printer used to log
all events processed by the CP-220A. A cable of the
appropriate length is required to join the printer and the
receiver and must be equipped with
Centronics-type
connectors at
each
end. See the box on page 1-14 for
additional information
Printer (No. 132 Cable)
A similar connection can be made between the printer and
the receiver by using this alternate printer port, although
it's less common and requires a nonstandard cable.
To DTE (No. 133 Cable)
This connector (designated here as DTE [
Data Terminal
Equipment
]) feeds the "raw" data processed by the CP-220A
directly to the serial communications (or RS-232) port of a
computer, which, when used in conjunction with the
appropriate Central Station Automation Software, can
expedite and simplify the job of monitoring alarms.
The cable plugged into this port is known as a
serial
cable; the
end of this cable at the CP-220A is a 25-pin "DB"-type (male)
connector; its other end will vary according to the type of serial
port provided by the computer, and may have either 9 or 25
pins. The FBI No. 133 is a UL-Listed custom-made cable that
provides the proper wiring and required connectors for this
purpose.
Information about interfacing the CP-220A with a Central
Station
Automation System
is further discussed in
Section 2
(see pages 2-73 and 2-74).
To DCE
This connector (designated here as DCE [
Data
Communications Equipment
]) is used to feed the "raw" data
processed by the CP-220A directly to the communications

What Kind of Printer?
What Kind of Cable?
Even with an Automation System installed, a printer
that can log the events processed by the CP-220A
is highly desirable for several reasons:
• it prints a hard-copy reference of all CP-220A
activities as they occur
• resulting printouts can be used for diagnostic
purposes
• such printouts represent a legal record of the
receiver's operation and may be needed for this
purpose.
The best type of printer for event logging is a
common
Dot Matrix Printer equipped with a parallel
(also known as a
Centronics) interface. It must be
connected to the receiver with a suitably long cable
(not to exceed 10 feet), equipped with a
Centronics
connector at each end and secured by clips for that
purpose.
Virtually any such printer will be suitable, but for
Central Stations that must meet Underwriters
Laboratories requirements, only printers and cables
"listed" by UL may be used. If this is the case, FBI
can supply a custom-made cable (No. 132A) for this
purpose. Additionally, a list of several printers that
have been recognized by UL for use with the
CP-220A appears below. Because this list is
changeable and printers are continually being
added and withdrawn from the market, feel free to
contact FBI (at (800) 645-7492) to obtain a revised
listing:
• any Centronics-manufactured printer
• ADEMCO No. 6960-1 • Epson LX-80 or RX-80
• Okidata 82, 82A, 86P, 92P, 93P, and 182
