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-
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
Each circuit has its own status LED that flashes to
indicate proper polling and lights steadily when the
output has been activated.
Multi-Mod Six Zone

• 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.
