Gamewell-FCI MMI-6SF Multi-Mod Six Zone Interface Module
The Velociti® Series, multi-mod six zone interface module (MMI-6SF) provides six Style B (Class B) or three Style D (Class A) supervised initiating device circuits (IDC) suitable for use with UL® Listed conventional 2-wire smoke detectors as well as any normally open contact device.
The Velociti® Series uses a communication protocol that substantially increases communication speed between the sensors and certain Gamewell-FCI analog addressable fire alarm controls.
These devices 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 earlier designs.
The MMI-6SF connects to the signaling line circuits (SLC) of the Gamewell-FCI analog addressable series fire alarm control panels.
Each of the MMI-6SF initiating device circuits occupies its own address on the system’s SLC, allowing each to be fully programmable 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 circuit is automatically assigned to its own subsequent address.
The MMI6SF 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.
Two multimod series units can be mounted in one MBB-2 cabinet. Additional mounting options include the MCH-6 chassis that can accommodate six multi-mod series modules. The MCH-6 chassis can be installed in a custom cabinet or mounted in the MBB-6 cabinet, allowing up to six multi-mod series modules in one cabinet. The initiating device circuit of the MMI-6SF can support a maximum line resistance of up to 40 ohms, allowing linear heat detection devices to be used.
The MMI-6SF is ideal for applications requiring a centralized location of circuits. As many as sixty initiating device circuits may be located in a cabinet that is only 12.63” H x 24” W x 6.5” D in dimension, saving valuable wall space in mechanical rooms and electrical closets and reducing the cost of installation.
