Fire-Lite MMF-300 Addressable Monitor Module
General: Four different monitor modules are available for Fire-Lite's intelligent 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 or monitor and power a circuit of two-wire smoke detectors (MMF-302).
MMF-300 is a standard-sized module (typically mounts to a 4''[10.16cm] square box) that supervises either a Class A (style D) or Class B (style B) circuit of dry-contact input devices.
- 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 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 MMF-300 can be used to replace M300 modules in existing systems.
Use to monitor a zone of four-wire smoke detectors, manual fire alarm pull stations, water flow 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 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.
Each MMF-300 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/normal/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).
Nominal operating voltage: 15 to 32 VDC.
Maximum current draw: 5.0 mA (LED on).
Maximum operating current: 375 uA (LED flashing).
Maximum IDC wiring resistance: 1500 ohms.
Temperature range: 32o F to 120o F (0o C to 49o C).
Humidity range: 10% to 93% noncondensing.
Dimensions: 4.5" (11.43 cm) high x 4" (10.16 cm) wide x 1.25" (3.175 cm) deep. mounts to a 4" (10.16) square x 2.125" (5.398 cm) deep box.
MMF-300, MMF-302 , and MDF-300 modules mount directly to a standard 4 '' (10.16 cm) square, 2.125" (5.398 cm) deep, electrical box. They may also be mounted to the SMB500 surface-mount box. Mounting hardware and installation instructions are provided with each module. All wiring must conform to applicable local codes, ordinances, and regulations. These modules are intended for power-limited wiring only.
