Addressable Monitor Modules
General
Four different monitor modules are available for Fire•Lite's
intelligent control panels to suit a variety of applications. Moni-
tor 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-302(A)).
MMF-300(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.
MMF-301(A) is a miniature monitor module a mere 1.3" (3.302
cm) H x 2.75" (6.985 cm) W x 0.5" (1.270 cm) D used to super-
vise a Style B (Class B) circuit of dry-contact input devices. Its
compact design allows the MMF-301(A) to be mounted in a
single-gang box behind the device it monitors.
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 in intelligent, two-wire systems.
LiteSpeed™ is a communication protocol developed by
Fire•Lite Engineering that greatly enhances the speed of com-
munication between analog intelligent devices. Intelligent
devices communicate in a grouped fashion. If one of the
devices within the group has new information, the panel CPU
stops the group poll and concentrates on single points. The
net effect is response speed greater than five times that of
other designs. designs.
MMF-300(A) Monitor Module
• 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 MS-9600 series
panels, 01 – 99 on other compatible systems.
• LED flashes during normal operation and latches on steady
to indicate alarm.
The MMF-300(A) Monitor Module is intended for use in intelli-
gent, two-wire systems, where the individual address of each
module is selected using the built-in rotary switches. It pro-
vides 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 MMF-300(A) can be used to replace M300(A)
modules in existing systems.
MMF-300(A) APPLICATIONS
Use to monitor a zone of four-wire smoke detectors, manual
fire alarm pull stations, waterflow devices, or other normally-
open dry-contact alarm activation devices. May also be used
to monitor normally-open supervisory devices with special
supervisory indication at the control panel. Monitored circuit
MMF-300(A) (Type H)
may be wired as an NFPA Style B (Class B) or Style D (Class
A) Initiating Device Circuit. A 47K ohm End-of-Line Resistor
(provided) terminates the Style B circuit. No resistor is
required for supervision of the Style D circuit.
MMF-300(A) OPERATION
Each MMF-300(A) uses one of the available module
addresses on an SLC loop. It responds to regular polls from
the control panel and reports its type and the status (open/nor-
mal/short) of its Initiating Device Circuit (IDC). A flashing LED
indicates that the module is in communication with the control
panel. The LED latches steady on alarm (subject to current
limitations on the loop).
