ORDERING INFORMATION
GENERAL DESCRIPTION
The 46131 Alarm Processing Unit (APU) gathers alarm information from TBOS interrogator ports and local discrete
alarm points. Three responder ports send the information to
alarm reporting equipment in various protocols.
A front panel LED display shows if there are any alarms or
failed TBOS displays.
Wiring is done at the back of the APU.
Before operating the APU, it must be configured. Connect a
dumb terminal or programming paddle to an RS-232 configura-
tion port on the APU. The configuration is backed-up by a
battery.
WARNING: When power is applied to the APU, negative battery voltage is
present at pins 54 and 56 of connector P2 and at any alarm
inputs wired to negative battery. For safety, cover these pins
with protective insulation. Keep the plastic front panel cover
closed during normal operation.
NOTE: This section lists the different options available for this product. To order any of the avail-
able options, contact Dantel Inside Sales through our toll-free number, 1-800-432-6835.

RESPONDER PORTS
Responder ports send alarm information to alarm reporting
equipment.
All options
Ports 1 and 2 can be either an RS-422/485 or RS-232 interface.
The RS-422/485 receive input can be terminated with 182 ohms
(switch option).
If RS-232 is used on ports 1 or 2, RTS/CTS handshaking can be
used. RTS/CTS handshaking enables communication through an
external modem on ports 1 and 2.
Port 3 is not used.
Options -20 and -21
Port 4 communicates through a optional 202 Modem subassem-
bly that plugs into the main circuit board. The modem operates
as a Bell 202 full-duplex tone modem. It has a data rate of
1200 baud. The modem provides:
♦Test points to measure the transmit and receive signal levels.
♦A potentiometer to adjust the transmit level.
♦An LED to indicate when the carrier signal is present.
The test points and potentiometer are accessible through a
window in the back panel of the APU.
All the responder ports communicate with either DCP, DCPF,
TBOS, or TABS protocol.
CONFIGURATION PORT
To program the APU to operate, connect a programming paddle
or dumb terminal to the RS-232 configuration port. The paddle
plugs into the RJ-11 connector on the front panel. The dumb
terminal connects to C1 on the front panel or at P3 on the back
panel.
LOCAL ALARM AND ACKNOWLEDGEMENT
Wire external audible or visual devices, such as a bells or lights,
to the APU for local alarm monitoring. When there is an alarm,
a relay in the change-of-state (COS) circuit operates the device.
If the alarm device is operating and another alarm occurs, the
relay will pulse once.
Depending on how the APU has been programmed, the relay
returns to its non-alarm state either (1) when all the alarms
clear or (2) when a timer expires after 15 minues. Manually
reset the relay either by applying a ground at the ACK COS
input or by pushing the front panel acknowlege button.
CIRCUIT DESCRIPTION
UPDATED

PAGE 6 46131-0598 <90-00018>
PUSH BUTTONS AND LED DISPLAY
On the front panel are five push buttons and five seven-segment
LED displays. They:
♦Show if there are alarms or failed TBOS displays.
♦Indicate if the TBOS interrogator ports are transmitting and
receiving data.
♦Reset the APU’s microprocessor.
♦Acknowledge alarms.
♦Indicate alarm location.
POWER
The APU operates on -21 to -56 VDC applied at a connector on
the front panel. Power goes through fuse F1 (two amperes) to an
on-board power supply. Power also goes to wire-wrap pins 54
and 56 of connector P2. Use pins 54 and 56, which are limited to
15 mA of current, to provide power to alarm inputs 25-32.
If the fuse fails, the fuse alarm (FA) LED on the front panel
lights. A relay also operates an external alarm.
CIRCUIT DESCRIPTION

WIRING
CAUTION: To avoid possible damage to the unit, do not make any
connections to the APU if the power is connected and turned
on.
NOTE: When cabling to the APU, leave sufficient slack in the cabling
to permit the internal printed circuit board to slide out from
the front panel (refer to Fig. 5). This allows replacement of the
circuit board without having to rewire the connectors.
If the wire bundle extending out one side of the unit is too thick
to permit closing the plastic front cover, divide the wiring so
some of it comes out the right side of the unit and some of it
extends out the left side of the unit.

To use a programming paddle:
Connect the programming paddle to the RJ-11 connector on the
front on the panel.
To use a dumb terminal:
Connect a dumb terminal or computer operating as a dumb
terminal to wire-wrap pins 53, 54 and 55 of connector P3 on the
back panel (refer back to Table H) or connect it to C1 on the
front panel. Refer to Fig. 9 for a drawing showing how connector
C1 is wired. Set up the dumb terminal or computer for 9600
baud, eight data bits and one stop bit.
FIG. 9 - DB9 CONNECTOR WIRING
WARNING: Do not connect a dumb terminal or a computer emulating a
dumb terminal directly to the DB9 connector. The DB9
connector is not a true RS-232 interface when connecting to a
terminal. Pin 9 has +5 VDC on it. A special cable is available
from Dantel that has pin 9 open. You can order the cable by
part number A15-46133-00.
