Mircom MIX-4041 is an intelligent addressable mini dual-input monitor module designed to supervise two independent contact circuits while using a single address on a compatible MGC fire alarm system. Its compact size allows installation in a single-gang junction box, and an onboard LED indicates module status during normal operation and alarm conditions.

The module can be configured for one Class A input or two Class B inputs. In Class A operation, an internal end-of-line resistor eliminates the need for a separate EOL resistor. It is designed for use with compatible Mircom addressable fire alarm control panels and supports quick, reliable monitoring of external initiating circuits.

Specifications:

Features:

• • Circuit Monitoring: Provides two independent contact monitoring circuits while using only a single address on the Signaling Line Circuit (SLC) loop.
• • Input Modes: Supports either one Class A circuit (with internal End-of-Line [EOL] resistor, requiring no external resistor) or two independent Class B circuits.
• • Physical Design: Compact unit engineered to fit inside a single-gang junction box.
• • Status Indicator: Features a panel-controlled red LED indicator that flashes during normal operation and stays steady when an alarm is triggered.
• • Addressing: Device address is configured electronically using the MIX-4090 programmer tool (remember to disconnect the loop or short SLC+/SLC- before programming to protect other devices).
• • Common Applications: Used to supervise external devices such as water flow switches, tamper switches, and manual pull stations.
• • Operating Temperature: 32°F to 120°F (0°C to 49°C).
