FireLite’s MMF-302-6 six-zone interface module provides an interface between the intelligent alarm system and a two-wire conventional detection zone. A common SLC input is used for all modules, and the initiating device circuits share a common external supervisory supply and ground. Otherwise, each module operates independently from the others. The first module is addressed from 01 to 154 while the remaining modules are automatically assigned to the next five higher addresses. Provisions are included for disabling a maximum of two unused modules. Al two-wire detectors being monitored must be two-wire-compatibility-listed with the modules. The MMF-302-6 transmits the status of a zone of two-wire detectors to the fire alarm control panel. Status conditions are reported as normal, open, or alarm. The interface module supervises the zone of detectors and the connection of the external power supply. Each MMF-302-6 module has panel-controlled bicolor LED indicators. The panel can cause the LEDs to blink, latch on, or latch off.
• Six addressable Class B or three addressable Class A initiating device circuits. • Removable 12 AWG (3.1 mm²) to 18 AWG (0.78 mm²) plugin terminal blocks. • Status indicators for each point. • Unused addresses may be disabled. • Rotary address switches. • Class A or Class B operation. • LiteSpeed or CLIP operation. • Mount one or two modules in a BB-2F cabinet (optional). • Mount up to six modules on a CHS-6 chassis in a BB-6F cabinet (optional). • Mounting hardware included.
Standby current: 2.0 mA (SLC current draw with all addresses used; if some addresses are disabled, the standby current decreases). Alarm current: 40 mA (assumes all six LEDs solid ON). Temperature range: 32°F to 120°F (0°C to 49°C). Humidity: 10% to 85% noncondensing. Dimensions: 6.8"" (172.72 mm) high x 5.8"" (147.32 mm) wide x 1.25"" (31.75 mm) deep. Shipping weight: 1.1 lb. (0.499 kg) including packaging. Mounting options: BB-2F cabinet, CHS-6 chassis, or BB-6F cabinet. Wire gauge: 12 AWG (3.1 mm²) to 18 AWG (0.78 mm²). MMF-302-6 is shipped in Class B position: Remove shunt for Class A operation. Maximum SLC wiring resistance: 40 or 50 ohms, panel dependent.
