4098-5268 – MX Photo/Heat/CO Sensor-Isolator

The Simplex 4098-5268 MX Photo/Heat/CO Sensor-Isolator is a triple-sensor device in the Simplex MX Addressable series, integrating three detection functions:

• Photoelectric sensor for smoke detection

• Heat sensor

• Carbon Monoxide (CO) sensor for toxic gas detection

Additionally, the unit features a built-in isolator that protects the MX loop circuit during short-circuit faults, ensuring reliable fire detection system operation.

Key Features

• Comprehensive and accurate detection – Simultaneously monitors smoke, heat, and CO levels for a complete fire profile, significantly reducing false alarms.

• Internal isolator – Automatically isolates short-circuit conditions on the MX loop to maintain system functionality and reliability.

• Self-monitoring and self-test – Supports continuous device supervision, integrated self-testing, and optional connection to a remote LED indicator for status signaling.

• Soft Addressing (intelligent addressing) – Enables quick and error-free address assignment via QR code using the Digital Enrollment application.

• MX Fastlogic algorithm – Processes combined smoke, heat, and CO data to generate precise fire alarms while minimizing nuisance alarms.
