Four monitor modules are available for Fire-Lite Alarms MS-9050UD, MS-9200UDLS, and MS-9600 intelligent fire alarm control panels to suit a variety of applications. Monitor modules are used to supervise a circuit of dry-contact input devices, such as conventional heat detectors and pull stations, or monitor and power a circuit of two-wire smoke detectors.
MMF-300(A) is a standard-sized module that supervises either a Style D (Class A) or Style B (Class B) circuit of dry-contact input devices.
MMF-301(A) is a miniature monitor module a mere 1.3" (3.302cm) used to supervise a Style B (Class B) circuit of dry-contact input devices.
MMF-302(A) is a standard-sized module used to monitor and supervise compatible two-wire, 24 volt, smoke detectors on a Style D (Class A) or Style B (Class B) circuit.
MDF-300(A) is a standard-sized dual monitor module used to monitor and supervise two independent two-wire Style B (Class B) dry-contact initiating device circuits (IDCs) at two separate, consecutive addresses.
Built-in type identification automatically identifies these devices as a monitor module to the control panel.
