General Information

1.2.1 Warnings: Before Programming
1. All applicable codes and standards should be considered when programming the
Control Unit.
2. The Control Unit continues to monitor input circuits and devices and acts according to
the current program settings if an alarm is received while it is being programmed.
3. Loading a new database erases the current database before loading the new database.
If the new database is not loaded after the erasure, the panel will not operate.
4. The database internal revision number included must match the number required by the
MR2 program, otherwise a Database Mismatch trouble condition is generated. This
condition disables the panel until a correct MR2 program is loaded.
5. The database must be completely loaded for it to be considered valid. The program
keeps track if the last database load was valid/complete or not. An invalid database load
disables the panel until a valid database load is done.
1.2.2 Downloadable Database
The panel uses a downloaded database for input circuit programming. This database includes
the addressable devices on-line, and the Zone LEDs, Bells, Functions Relays and Control
Modules activated by addressable devices. This database is created and downloaded from an
IBM compatible computer using the Modul-R Human Interface (MHI) program. Refer to the
Modul-R Human Interface User Guide for instructions on downloading the database.

Networks

1.3.1 General
The MR-2200 can be incorporated into a network including other MR-2900 panels and MR-
2944 annunciators. Though up to 254 panels and annunciators can be supported by the
network, such a network would probably be too large to properly maintain. The network can be
setup for single building or multiple building operation.

All communications are stopped during the database load. This causes a trouble
to be recorded by those units that are normally communicating with the panel.
