Edwards KIR-OSHCD Smoke Heat CO Detector

The Edwards KIR-OSHCD is a commercial smoke, heat, and carbon monoxide detector designed for compatible Edwards fire alarm systems. It combines three life-safety detection functions in one low-profile device, helping identify smoke, elevated temperature conditions, rapid temperature increases, and hazardous carbon monoxide levels.

The detector includes automatic environmental compensation, continuous self-diagnostics, electronic addressing, and visible status indication. This product is intended exclusively for commercial fire alarm installations.

Product Functions

• Detects airborne smoke
• Detects fixed-temperature heat conditions
• Detects rapid temperature increases
• Monitors life-safety carbon monoxide levels
• Reports fire and CO alarm conditions
• Performs continuous self-diagnostics
• Identifies maintenance conditions

Electrical & System Information

The KIR-OSHCD operates on compatible Edwards signaling line circuits and reports smoke, heat, CO, alarm, and maintenance conditions to the connected fire alarm control panel.

Rotary switches allow technicians to set the device address during installation. A compatible Edwards detector base is required and may be sold separately.

Features

• Combined smoke, heat, and CO detection
• Integrated carbon monoxide sensor
• Fixed-temperature heat detection
• Rate-of-rise heat detection
• Automatic environmental compensation
