OPTION NUMBER FEATURES
B11-46020-38 Multiple Alarm Processor equipped with 46600-38 Firmware.
GENERAL DESCRIPTION
The 46020-38 Multiple Alarm Processor (MAP) is part of a Dantel 460 Alarm and Control System. It is a 46020 MAP
with 46600-38 firmware. This chapter describes the features of
the MAP and firmware, and also how they work as part of a
complete system.
MAP PORTS
The firmware allows a MAP to operate in several different
applications of a 460 Alarm and Control System. The MAP
provides three different data interface points, and all of them
are affected by the firmware. Here is a brief description of each
of the ports:
Master Port
♦Connects to an alarm center that reports alarm data and
issues control point commands.
The alarm center may be a personal computer or an alarm
system master. For example, it could be an E-System master
the MAP communicates with through a 46033 E-System
Adapter.
♦May also connect to another device as an intermediary
point in reporting data to an alarm center.
This device could be a 46062 General Purpose Processor or
another MAP (using DCP, TBOS or DCPF protocol).
Printer Port
♦Connects to a standard ASCII (VT-100) terminal, with or
without a printer,
or
♦Connects to Dantels 46001 Status Monitor.
You can use the terminal or status monitor for local alarm
reporting. The terminal also can operate controls.
NOTE:
In order to work, the MAP must
be configured. Configuration al-
lows you to define how the MAP
will function, such as what
alarms it will poll and what con-
trol points it will operate. Refer
to the Switch Settings chapter.

46020-38-0299<90-00029> PAGE 3
♦May also operate as a master port (when youre using TBOS,
DCP, or DCPF protocol on it).
Data Port
♦Can process up to 32 displays (2,048 points) of alarms and
controls. There can be any combination of alarm and control
displays; for example, 32 displays of alarms and 32 displays
of controls.
♦These may be discrete alarm points connected to 46009 or
46010 Multiple Alarm Transmitters (MATs) and control
points wired to 46028 or 46029 Control Point Modules
(CPMs).
♦Can communicate with alarm and control points through
TBOS serial equipment.
♦Can be wired to either a 46022-12 Multiple Alarm Combiner
(MAC), which provides eight RS-422 serial ports or a
46022-20 MAC, which provides one port equipped with a
communications subassembly.
TYPICAL SYSTEMS
These diagrams show examples of how you can use the 46020
MAP in typical systems. Fig. 1 shows a basic system and Fig. 2

DATA CAPACITY
Master and Printer Ports
The MAP can handle 2,048 alarm and control points (32 dis-
plays) except when you use TBOS protocol.
When TBOS is used on the master and printer ports, the
amount of alarm data the MAP can address is limited. TBOS is
limited to eight displays of alarms and controls on the master
port and an additional eight displays of alarms and controls on
the printer port (a total of 16 displays).
Data Port
With DCM, DCP, or DCPF protocols on the master and/or
printer ports, the data port can communicate with up to 2,048
alarm and control points. See Fig. 1 for an illustration of these
protocols.
If TBOS is used on the master port, the data port is limited to
512 alarm and 512 control points (eight displays).
If TBOS is used on both master and printer ports, the data port
can communicate with up to 1,024 alarm and 1,024 control
points. See Fig. 3 for an illustration of TBOS on master and
printer ports.

PROTOCOLS
There are three communications protocols available for the
master port, three for the printer port (plus a printer syntax
using ASCII format), and two for the data port. Refer to Fig. 1.
Master and Printer Ports
DCP - This protocol is used when the MAP interfaces another
MAP, a personal computer, or an external alarm master (such as
an E-System master interfaced through an E-System Adapter).
DCPF - This is a modified DCP protocol with improved error
detection. It is used when the MAP interfaces another MAP, a
General Purpose Processor, or a Status Monitor.
TBOS - This protocol is used when the MAP interfaces a TBOS
serial port, such as on an E2A remote or on the data port of
another MAP (refer to Fig. 2).
Printer - This syntax establishes the coding for the printer port
to interface a standard ASCII (VT-100) terminal. The Printer
Syntax chapter contains the user commands for operating the
terminal.
Data Port
TBOS - This allows the MAP to communicate with TBOS serial
equipment, such as another MAP as shown in Fig. 2.
DCM - This protocol communicates with discrete points only.
The MAP interrogates MATs (Multiple Alarm Transmitters) for
alarm data and operates control points on CPMs (Control Point
Modules).
NOTE:
Only one protocol may be used on
port 1. Choose DCM or TBOS.
GENERAL DESCRIPTION

INTERFACES
Master Port
The master port requires a subassembly to be mounted on the
MAP in order to provide the proper interface to other equip-
ment. When TBOS is used on the master port, the most com-
mon is a 49008 subassembly providing an RS-422 interface.
Other subassemblies are available for special applications.
When DCP or DCPF is used on the master port, the subassem-
bly is usually a 49009 or 49029 with an RS-232 interface.
Printer Port
The printer port has a built-in RS-232 interface. If you require a
different interface on the printer port, you can add a Dantel
46035 Converter Module with the appropriate subassembly
between the MAP and the other equipment.
Data Port
The data port of the MAP communicates through transistor-
transistor logic (TTL). This means communications cannot
extend beyond the shelf where the MAP is installed. To commu-
nicate beyond the shelf, you must connect the data port to a
46035 Converter Module, 46022 Multiple Alarm Combiner
(MAC) or other device (for example, a 46034 Hubbing Module)
for conversion to the appropriate data communications interface.
A 46022-12 MAC has eight communications channels or ports.
The MAP's data port supports multiple MACs.
In communicating with alarm and control points, the data port
can use DCM protocol (port one only) or TBOS protocol (ports
one through eight) on any of the MAC channels.
However, only one protocol can be used on any one channel. The
protocol(s) used on the data port do not have to be the same as
those used on the printer and master ports. For example, DCP
could be used on the master port, PRINTER syntax on the
printer port, and DCM and TBOS on the data port.

interfaces.

BATTERY BACKUP
The MAP has a battery backup to preserve the system configu-
ration information that has been placed in memory. You can set
switches on the MAP to retain the information in memory, even
if the power to the MAP is interrupted. If you do not set the
switches to retain the memorys contents, configuration informa-
tion is erased when the power is restored. To learn how to set
these switches, refer to the Switch Settings chapter.
RESET
On the front panel of the MAP, there is a recessed reset button.
When you push this button, it executes a complete, or hard,
reset. The effect is the same as removing power from the MAP.
When power is restored later, the information in the MAPs
memory is saved ... only if you have set the switches to retain it
(see Battery Backup paragraph). If you have not set the
switches to save the memory, it will be erased.
The MAP also has a protective (watchdog) circuit. If the
software encounters a problem and is unable to refresh the
protective circuit, a complete reset automatically occurs after 1.2
seconds.
GENERAL DESCRIPTION

DIP SWITCHES
There are seven banks of DIP switches on the MAP. Each bank
has eight levers, and the banks are numbered S1 through S7.
Refer to Fig. 5 for a DIP switch location diagram.

♦Regulated power supply.
Binary data goes to and from the microprocessor by way of the
systems input/output. It is applied to each port through a series
of protectively buffered ACIAs (Asynchronous Communications
Interface Adapters).
Master port
Communicates with an external personal computer or other
alarm reporting equipment through a plug-in subassembly.
Printer port
Communicates with an external standard ASCII (VT-100)
terminal, personal computer, or other alarm reporting equip-
ment through an on-board RS-232 interface.
Data port
Communicates either directly or through other Dantel interface
modules with remote alarm and control devices using seven TTL
buses designated TXD, RXD, RTS, CTS, DCD, DSR, and DTR.
By setting switches, you can determine the default configura-
tions of the ports. These configurations affect the way the MAP
functions when you begin operation.
The on-board regulated power supply uses -21 to -56 VDC input
power to provide +5 and ± 12 VDC regulated power for the
modules circuits. The power supply also provides operating
power for the master port communications subassembly.
