BEFORE INSTALLING
This information is included as a quick reference installation guide. Refer to
the appropriate Fire•Lite control panel installation manual for detailed sys-
tem information. If the modules will be installed in an existing operational
system, inform the operator and local authority that the system will be tempo-
rarily out of service. Disconnect the power to the control panel before install-
ing 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 removed from the body. The module housing should also
be grounded.
GENERAL DESCRIPTION
The MMF-302-6 Six Zone Interface Module is intended for use in an intelli-
gent 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.
A list of compatible two-wire System Sensor Smoke detectors for use with the
MMF-302-6 is available on the System Sensor website at systemsensor.com.

SPECIFICATIONS
MMF-302-6 Six Zone Interface Module
COMPONENTS
Following are descriptions of the MMF-302-6 mounting frameworks. There are
two mounting options for MMF-302-6 modules:
• Up to six MMF-302-6 modules can be installed on a CH-6 in a BB-6F
cabinet
• One or two MMF-302-6 modules can be installed in a BB-2F cabinet
Chassis
The CH-6 chassis is used to mount MMF-302-6 modules in a BB-6F cabinet.
It accommodates up to six MMF-302-6 modules in a single cabinet row three
modules wide and two modules deep.
FIGURE 1. CH-6 CHASSIS
C0206-00
The BB-2F cabinet has a built-in chassis that will accommodate one or two
MMF-302-6 modules.

The front MMF-302-6 module positions of each chassis are offset below the
rear MMF-302-6 module positions so that all of the status indicators are visible.
Cabinets
A BB-6F will house the CH-6 chassis with up to six MMF-302-6 modules in-
stalled on it. Refer to cabinet installation documents for dimensions.
