Description

The Mircom MIX-100R Intelligent Addressable Relay Module provides reliable relay control for compatible Mircom addressable fire alarm systems. The module connects to the same addressable loop as initiating devices and provides two isolated sets of Form-C relay contacts for controlling auxiliary equipment.

Designed as part of Mircom’s MIX-100 Series Alpha intelligent addressable modules, the MIX-100R provides a practical interface between the fire alarm system and equipment requiring normally open or normally closed relay operation. Typical applications can include fan control, door closure, and other auxiliary building functions.

Intelligent Addressable Relay Control

The Mircom MIX-100R allows a compatible fire alarm control system to operate external equipment through its relay contacts. Because the module is addressable, the fire alarm system can identify and control the device through the signaling line circuit.

The module provides two isolated sets of Form-C contacts, offering normally open, normally closed, and common relay connections. Therefore, installers can integrate the module with a variety of auxiliary control applications.

Two Form-C Relay Outputs

A major feature of the MIX-100R is its dual Form-C relay configuration. These dry relay contacts allow the fire alarm system to interface with equipment that requires contact closure or contact transfer.

Typical applications may include:

• Fan operation
• Door closure systems
• Auxiliary equipment control
• Building system interfaces
• Other normally open or normally closed control applications

The relay contacts are rated at 2A at 24 VDC and 0.5A at 30 VAC, according to Mircom’s MIX-100 Series product literature.

Low Current Addressable Design

The Mircom MIX-100R has a specified current consumption of approximately 250 µA, helping minimize the load placed on the addressable circuit.

The MIX-100 Series operates from 16–28 VDC, while the relay module communicates through the compatible Mircom addressable system. This design allows the module to provide relay control without requiring a separate conventional control circuit for module communication.

Red LED Status Indicator

The MIX-100R includes a red LED indicator associated with relay operation. According to Mircom documentation, the activated LED follows the state of the relay contacts. Therefore, technicians have a convenient visual indication of module operation during installation, testing, and system servicing.

Addressable Module Configuration

The Mircom MIX-100R uses onboard DIL switches for address configuration. The installation instructions specify that switch segments are used to select the module address, allowing technicians to assign the module within the compatible addressable system.

This individual addressing allows the fire alarm control panel to operate the relay according to the programmed system sequence.

Commercial Fire Alarm Applications

The MIX-100R can be used where an addressable fire alarm system needs to control external equipment through relay contacts. Applications can include commercial buildings, institutional facilities, schools, healthcare properties, offices, and other facilities using compatible Mircom fire alarm equipment.

For example, the module can provide relay interface functions for fan control or door closure equipment. Its two Form-C contact sets also provide flexibility for applications requiring either normally open or normally closed operation.

Installation and Compatibility

Before installing the Mircom MIX-100R, technicians should confirm compatibility with the fire alarm control panel and verify the required relay load. The connected equipment must remain within the module’s specified contact ratings.

The module should also receive the correct address setting before system commissioning. Wiring should follow Mircom’s official installation instructions, including the specified loop connections and relay contact configuration.

Qualified fire alarm professionals should install, program, and test the module according to the approved system design, Mircom technical documentation, and applicable fire alarm requirements.

Overall, the Mircom MIX-100R Intelligent Addressable Relay Module provides a flexible way to integrate auxiliary equipment with compatible Mircom addressable fire alarm systems. Its two Form-C relay outputs, low current consumption, addressable operation, and compact design make it suitable for a variety of professional fire alarm control applications.
