2.9 GIM-232 Galvanic Isolation Module for RS-232 Interface
The GIM-232 Galvanic Isolation Module for RS-232 interface allows
the connection of grounded serial devices such as a PC or a serial
printer to the ADR-3000 to be free of ground fault disturbance.
When connecting a PC or a printer to the control panel, place the
GIM-232 in the lower part of the internal mounting plate (see
figure 2).

Usually laptop computers are not grounded; therefore do not require
the galvanic isolation module.
Both jumpers should be in the lower position (

) when connecting
a PC to the control panel’s RS-232 port. Both jumpers should be in
the upper position (

) when connecting a printer to the control
panel’s RS-232 port.

The MCID-34 incorporates an auto disconnect feature that
allows the use of the telephone line for other uses, whilst
providing priority to the fire alarm system.
The MCID-34 can operate in one of two modes:
•
C
ALLER
ID
– allows preprogramming of authorized
telephone numbers. Only a recognized incoming phone
call will be answered by the modem, disconnecting the
subscriber’s phone-set. This mode requires the local
telecomm infrastructure to support caller ID.
•
A

– the modem will respond automatically
after a preprogrammed number of incoming rings.

Setting the MCID-34 operating parameters and authorized phone numbers can be
configured from the ADR-3000 Utilities Menu.
