BEFORE INSTALLING
If the modules will be installed in an existing operational system, inform the
operator and local authority that the system will be temporarily out of service.
Disconnect the power to the control panel before installing the modules. This
system contains static sensitive components. Always ground yourself with a
proper wrist strap before handling any circuits so that static charges are re-
moved from the body. The module housing should also be grounded.
NOTICE: This manual should be left with the owner/user of this equipment.
GENERAL DESCRIPTION
The MMI-6SF Six Zone Interface Module is intended for use in an intelligent
alarm system. Each module provides an interface between the intelligent
alarm system and a conventional alarm system loop. A common SLC input is
used for all modules, and the initiating device loops share a common super-
visory supply and ground. Otherwise, each monitor operates independently
from the others. Each module has its own unique address.
A pair of rotary code switches is used to set the address of the first module
from 01 to 154. The remaining modules are automatically assigned to the next
five higher addresses. Provisions are included for disabling a maximum of two
unused modules to release the addresses to be used elsewhere. Each mod-
ule also has panel controlled bicolor LED indicators. The panel can cause the
LEDs to blink, latch on, or latch off.

COMPONENTS
Following are descriptions of the MMI-6SF mounting frameworks. There are
two mounting options for MMI-6SF modules:
• Up to six MMI-6SF modules can be installed on a CHS-6 in a CAB-3
Series, CAB-4 Series or
MBB-6
cabinet
• One or two MMI-6SF modules can be installed in a
MBB-2
cabinet
Chassis
The CHS-6 chassis is used to mount MMI-6SF modules in a MBB-6, CAB-3 or
CAB-4 Series cabinet. It accommodates up to six MMI-6SF modules in a single
cabinet row three modules wide and two modules deep.
