Fire Lite MDF 300 Dual Monitor Module | Reliable Fire Supervision
The Fire Lite MDF 300 is a dual monitor module designed for use with Fire-Lite’s addressable fire alarm control panels. It provides two independent 2-wire initiating device circuits (IDCs) at two separate, consecutive addresses.
Why Choose the Fire Lite MDF 300?
When it comes to expanding your fire alarm system’s capabilities without overcomplicating the wiring, the Fire Lite MDF 300 is the industry standard. Moving beyond basic monitoring, this device is engineered for reliability and ease of installation.
Unlike standard single modules, the Fire Lite MDF 300 allows you to monitor two separate circuits simultaneously. This “2-in-1” capability makes it an incredibly cost-effective solution for both retrofits and new construction projects, saving you space in the junction box and reducing hardware costs.

Key Features and Benefits
To understand why this module is a top-seller, here is a breakdown of the specific features that the Fire Lite MDF 300 offers:
Dual Circuit Monitoring: Effectively monitors two independent 2-wire Initiating Device Circuits (IDCs).
Addressable Intelligence: Communicates the status (normal, open, or alarm) of the monitored device back to the control panel.
Space-Saving Design: Mounts directly inside a standard 4-inch square electrical box.
High Compatibility: Seamlessly integrates with Fire-Lite SLC loops.
High Noise Immunity: The Fire Lite MDF 300 is built to resist interference, ensuring stable communication.
System Compatibility
One of the biggest advantages of the Fire Lite MDF 300 is its broad compatibility with legacy and modern systems. It is designed to work with Fire-Lite Alarm Control Panels (FACPs) that utilize the specific protocol for addressable devices.
Compatible Panels Include:
- MS-9050UD
- MS-9200UDLS
- MS-9600UDLS
Endurance Series (ES-50X, ES-200X)
Installation and Wiring
Installing the Fire Lite MDF 300 is straightforward, but it must be done in accordance with the installation manual and NFPA 72 codes. The module uses rotary switches to set the address. Because it is a dual module, it will automatically assign itself the address you select plus the next sequential number (e.g., if you set it to address 12, the second circuit acts as address 13).
Note on Installation: This unit mounts to a 4-inch square box with a minimum depth of 2.125 inches. No external power supply is required as communication and power are provided via the SLC loop.
Frequently Asked Questions (FAQ)
Does the Fire Lite MDF 300 require external power? No, the module draws its operating power directly from the SLC loop of the control panel.
Can I use the Fire Lite MDF 300 for pull stations and water flow switches? Yes, it is ideal for monitoring contact devices such as manual pull stations, water flow switches, and tamper switches.
