General FMM-1(A) is a standard-sized module (typically mounts to a 4″ [10.16 cm] square box) that supervises either a Style D (Class A) or Style B (Class B) circuit of dry-contact input devices. Features • Built-in type identification automatically identifies this device as a monitor module to the control panel. • Powered directly by two-wire SLC loop. No additional power required. • High noise (EMF/RFI) immunity. • SEMS screws with clamping plates for ease of wiring. • Direct-dial entry of address: 01 – 159 on FlashScan loops; 01 – 99 on CLIP loops. • LED flashes green during normal operation (programmable option) and latches on steady red to indicate alarm. The FMM-1(A) Monitor Module is intended for use in intelligent, two-wire systems, where the individual address of each module is selected using the built-in rotary switches. It provides either a two-wire or four-wire fault-tolerant Initiating Device Circuit (IDC) for normally-open-contact fire alarm and supervisory devices. The module has a panel-controlled LED indicator. The FMM-1(A) can be used to replace MMX-1(A) modules in existing systems.
