Mircom Technologies is a Canadian fire alarm manufacturer headquartered in Vaughan, Ontario, with a dominant market share in Canada and a growing installed base in the United States. Mircom systems are found in residential high-rises, hotels, hospitals, and commercial buildings throughout North America. As Mircom panels age, finding replacement parts requires understanding the platform families and sourcing channels. This guide covers Mircom’s main systems, compatible devices, and how to source parts.
Mircom’s Main Panel Families
Mircom produces several distinct fire alarm panel families, each with its own device ecosystem:
- FX-2000 Series: Mircom’s primary commercial addressable panel, available in 1-loop (FX-2000) and 2-loop (FX-2000-2L) configurations. The FX-2000 supports up to 250 addressable devices per loop using Mircom’s SLC protocol.
- TX3 Series: A newer, more advanced platform supporting large-capacity networked systems. The TX3 is Mircom’s flagship for hospitals, high-rises, and campus applications requiring multi-panel network configurations.
- MR-2000 Series: A mid-range addressable panel for smaller commercial applications. Shares many loop devices with the FX-2000 series.
- FR-Series: Mircom’s conventional panel range, used in residential and small commercial applications.
Compatible Detectors for Mircom FX-2000 and TX3
Mircom uses its own addressable loop protocol, which means loop devices must be Mircom-compatible. The main detector lines include:
- MMX-150: Mircom’s standard intelligent photoelectric smoke detector. The MMX-150 is the most widely installed detector on FX-2000 and TX3 systems.
- MMX-151: Photoelectric smoke detector with integrated 135°F fixed-temperature heat sensor—the dual-technology option for areas with environmental challenges.
- MMX-155: Heat detector in rate-of-rise and fixed-temperature configuration.
- MMX-130: Duct smoke detector housing for installation in HVAC systems.
Mircom detectors use a twist-lock base system. The most common base is the B501 (standard) and B501-ISO (with short-circuit isolator for Class A loops). Always replace bases that show contact oxidation or physical damage.
Mircom Addressable Modules
The FX-2000 and TX3 platforms use a range of addressable interface modules:
- MMX-200: Single-input monitor module for supervisory and alarm inputs (waterflow, tampers, conventional zones).
- MMX-201: Dual-input monitor module.
- MMX-300: Control relay module for fan shutdown, door holders, damper control, and elevator recall.
- MMX-301: Dual-output control module for complex control sequences.
- MMX-700: Audio/visual module for voice evacuation integration on TX3 systems.
Pull Stations and Notification Appliances
Mircom offers both addressable and conventional pull stations. The FMM-1 is the standard Mircom addressable manual pull station with dual-action activation and key reset. For notification appliances, Mircom’s NAC circuits are 24VDC compatible with standard horn/strobes from multiple manufacturers.
For high-visibility notification in large spaces, consider upgrading aging horn/strobes to modern multi-candela devices. The Simplex multi-candela horn strobe is an example of a high-output notification appliance suitable for large areas (verify compatibility with your panel’s NAC output before installation).
Batteries for Mircom Panels
Mircom panels use standard sealed lead-acid batteries in 12V configurations. Battery sizing must meet NFPA 72 (in the US) or ULC-S524 (in Canada) standby power requirements. In Canadian installations, CAN/ULC-S537 inspection requirements are particularly strict about battery condition documentation. Replace batteries on a 4-year cycle in high-temperature environments (above 77°F/25°C ambient) or on the standard 5-year cycle otherwise.
Sourcing Mircom Parts in the US
Mircom distributes through an authorized dealer network that is stronger in Canada than in the US. For US-based facilities managers and technicians, this can make parts sourcing challenging—especially for older FX-2000 systems where the installing contractor may no longer be active.
Life Safety Consultants sources Mircom-compatible and Mircom OEM parts for customers across North America. Our Mircom parts catalog includes detectors, bases, and modules for FX-2000 and TX3 systems. When ordering, have your panel model number and current firmware version available—Mircom occasionally releases device compatibility updates tied to firmware revisions.
TX3 vs. FX-2000: Parts Compatibility
The TX3 and FX-2000 share the MMX-series detector and module platform, which simplifies parts sourcing. However, the TX3 uses a higher-capacity SLC protocol than the FX-2000, and some advanced TX3 devices (such as the MMX-700 audio module) are not compatible with FX-2000 loop controllers. When sourcing detectors and basic input/output modules, TX3 and FX-2000 parts are generally interchangeable. For advanced modules and network cards, confirm panel compatibility before ordering.
Documentation and Firmware
Mircom’s programming software (Mircom FX Programmer and TX3 Toolbox) is available through Mircom’s dealer portal. Keep firmware up to date—Mircom periodically releases updates that address device compatibility issues and false alarm reduction algorithms. Outdated firmware combined with replacement detectors can cause unexpected behavior. Visit our full catalog for parts and contact our team for technical compatibility questions.
