Description
The Velociti™ Series, multi-mod six zone interface
module (MMI-6SF) provides six (6), Style B (Class
B) or three (3), Style D (Class A) supervised initiat-
ing device circuits (IDC) suitable for use with
U. L. Listed conventional 2-wire smoke detectors
as well as any normally open contact device.
The VelocitiTM Series use a communication proto-
col that substantially increases the speed of com-
munication between the sensors and certain FCI
analog addressable fire alarm controls. These de-
vices operate in a grouped fashion. If one of the
devices in the group has a status change, the
panel’s microprocessor stops the group poll and
concentrates on the single device. The net effect is
response speed up to five times greater than ear-
lier designs.
The MMI-6SF connects to the signaling line circuits
(SLC) of the FCI analog addressable series fire
alarm control panels. Each of the MMI-6SF initiat-
ing device circuits occupies its own address on the
system’s SLC allowing each to be fully programma-
ble in its control-by-event sequence of operation.
The address of the first initiating device circuit is
set with a pair of rotary dials. Each remaining cir-
cuit is automatically assigned to its own subse-
quent address. The MMI-6SF module includes an
address disable jumper matrix to allow a maximum
of two unused addresses to be turned off to free
these addresses for other purposes. An additional
pair of jumpers selects either Style B or Style D
circuit configurations.
Each circuit has its own status LED that flashes to
indicate proper polling and lights steadily when the
output has been activated.

Features
Each MMI-6SF module provides six (6), Style B
(Class B) or three (3), Style D (Class A) individually
addressable individually programmable initiating
device circuits.
Suitable for use with U. L. Listed, compatible 2-wire
conventional smoke sensors and normally open
contact devices.
Removable wiring terminal blocks allow ease of
installation and servicing terminal.
Blocks can accommodate 12 to 18 AWG wire.
Flexible jumper configuration feature allowing
one or two monitoring circuit addresses to be disabled.
Individual LED indicators*.
Ideal for retrofit applications.
As many as thirty-six (36), initiating device circuits in
one 12” x 24” x 6.5” cabinet.
Two (2), mounting cabinets available for two (2),
(MBB-2 cabinet) to six (6), (MBB-6 cabinet) units.
Bicolor LEDs flash green whenever the sensor is
addressed, and light steady red on alarm.*
Note: *Only the red LED is operative in panels that do not oper-
ate in Velociti™ mode.

Description (Continued)
www.DataSheet4U.com
Two (2), multi-mod series units can be mounted in
one MBB-2 cabinet. Additional mounting options
include the MCH-6 chassis that can accommodate
six (6), multi-mod series modules. The MCH-6 chas-
sis can be installed in a custom cabinet or can be
mounted in the MBB-6 cabinet allowing up to six (6),
multi-mod series modules in one cabinet.
The initiating device circuit of the MMI-6SF can sup-
port a maximum line resistance of up to 40 ohms
allowing the use of linear heat detection devices.
The MMI-6SF is ideal for applications where central-
ized location of circuits is required. As many as sixty
(60), initiating device circuits may be located in a
cabinet that is only 12.63” H x 24” W x 6.5” D in di-
mension, saving valuable wall space in mechanical
rooms and electrical closets and reducing cost of
installation.
