Secutron MRI-4030-ISO Intelligent Addressable Tri-Mode Heat Detector provides flexible heat detection with built-in short-circuit isolation. It can operate using fixed-temperature or rate-of-rise detection modes, allowing the detector to be matched to different environmental and application requirements.

Ideal for fire alarm installations requiring reliable heat detection in areas where smoke detection may be unsuitable. Integrated isolation helps maintain system circuit integrity during a wiring fault.

Specifications:

Features:

• • Detection Modes: Supports fixed temperature at 57°C (135°F) or 79°C (175°F), plus a rate-of-rise mode at 57°C (135°F).
• • Short-Circuit Isolation: The -ISO model includes a bi-directional isolator to protect against loop wiring faults.
• • Status Indicators: Features distinct LED status colors (steady red for alarm, flashing green for normal, and steady amber for fault/trouble).
• • Configuration: Easily configured using the handheld programmer MIX-4090.
