Mircom MIX-3300 Intelligent Thermal Heat Detector

The Mircom MIX-3300 Intelligent Thermal Heat Detector provides addressable temperature monitoring for compatible Mircom fire alarm systems. Part of the Alpha Series intelligent addressable detector family, it uses electronic temperature sensing technology to provide fast and accurate thermal detection.

Designed for use with the Mircom FX-350 Series platform, the MIX-3300 combines digital addressable communication with an adjustable temperature range. Its low-profile construction and interchangeable mounting-base options make it suitable for commercial and institutional fire alarm applications.

Intelligent Thermal Detection

The Mircom MIX-3300 uses electronic temperature sensing rather than a conventional mechanical heat-detection element. This design provides accurate temperature monitoring while allowing the detector to communicate its status digitally to the compatible fire alarm control panel.

Mircom identifies two heat-element settings for the detector: Mode 1 at 129°F (54°C) and Mode 5 at 212°F (100°C). The temperature configuration is controlled through the compatible FX-350 Series fire alarm control panel.

Addressable Digital Communication

Each MIX-3300 operates as an individually identifiable device on the compatible addressable fire alarm system. Mircom’s Alpha Series design stores the detector address in its mounting base using the MIX-ADD address card.

Because the address remains with the base, detector replacement can be simplified during system maintenance. A replacement detector can be installed without having to manually reassign the original point address.

Key Features

• Intelligent addressable thermal detection
• Adjustable temperature configuration
• 17–28 VDC operating range
• Automatic addressing with MIX-ADD card
• Low-profile detector design
• Multiple compatible mounting-base options

Electrical Specifications

The Mircom MIX-3300 operates from 17 to 28 VDC with a modulation voltage of 5 to 9 V. Mircom specifies a maximum alarm current of approximately 3.4 mA, surge current of 1.0 mA, and supervisory current of 500 µA.

These electrical characteristics allow the detector to operate directly on the compatible addressable circuit while maintaining continuous communication with the fire alarm control panel.

Adjustable Temperature Configuration

A major advantage of the MIX-3300 is its configurable thermal operation. Mircom’s documentation lists a 129°F (54°C) Mode 1 setting and a 212°F (100°C) Mode 5 setting.

This flexibility allows the detector to support different thermal detection requirements when properly configured through compatible Mircom fire alarm equipment.

Low-Profile Detector Design

The MIX-3300 belongs to Mircom’s Alpha Series of low-profile intelligent detectors. The detector installs into compatible mounting bases rather than having the field wiring terminate directly at the detector head.

Mircom identifies the MIX-2000 standard base and MIX-2001 E-Z Fit base for use with the MIX-3000 Series detector family. This modular arrangement can simplify installation, servicing, and detector replacement.

Commercial Fire Alarm Applications

The Mircom MIX-3300 can provide addressable thermal detection in commercial buildings, schools, offices, institutional facilities, mechanical spaces, and other locations using compatible Mircom addressable fire alarm equipment.

Heat detection can be useful in locations where environmental conditions make smoke detection less suitable. The appropriate detector mode, temperature setting, spacing, and placement should always follow the approved fire alarm system design and applicable requirements.

System Compatibility

The MIX-3300 is identified by Mircom as a compatible heat detector for the FX-350 Series fire alarm control panels. Mircom’s compatibility documentation cross-references the MIX-3300 with Apollo model 55000-450.

The MIX-3300 is a legacy product associated with the FX-350/351 platform. Mircom’s end-of-life documentation lists the MIX-3300 among the affected FX-350/351 products and parts. Therefore, technicians sourcing this detector for an existing installation should verify panel, base, and system compatibility before replacement.

Overall, the Mircom MIX-3300 Intelligent Thermal Heat Detector provides configurable addressable heat detection with electronic temperature sensing, digital communications, automatic base addressing, and a low-profile design for compatible Mircom fire alarm systems.
