Cooper Menvier CAH330 Intelligent Addressable Multi-Mode Heat Sensor

The Cooper Menvier CAH330 Intelligent Addressable Multi-Mode Heat Sensor is a high-performance thermal fire detector designed to operate seamlessly within Cooper intelligent addressable fire systems. Engineered for accuracy and reliability in challenging environments, this multi-mode sensor offers selectable heat detection modes—including fixed 77°C, fixed 92°C, and rate-of-rise—allowing installers to tailor the detection method to the specific fire risk or environmental condition.

With soft addressing, an integrated short circuit isolator, and 360° LED visibility, the CAH330 combines intelligent design with practical functionality. It is ideal for use in areas prone to false alarms from dust, steam, or fumes—such as kitchens, industrial zones, or workshops—where traditional smoke detectors may not be suitable.

Product Features

Multi-Mode Heat Detection

Offers three selectable detection modes:

• Fixed 77°C
• Fixed 92°C
• Rate-of-Rise
  Provides flexibility in matching detection mode to site-specific fire safety requirements.

Soft Addressing

Configured without the need for a manual address switch, making installation faster and reducing setup errors.

Integral Short Circuit Isolator

Enhances system reliability by isolating faulty sections of the loop during a short circuit, ensuring continued operation of the remaining system.

Single Loop Address

Each sensor occupies a single address on the fire alarm loop, optimizing system capacity and simplifying device management.

360° Visibility LED

Equipped with lightpipe technology, the bright red LED ensures full-angle alarm indication, making status identification easier from any viewing direction.

Drift Compensation

Automatically adjusts for environmental factors like dust buildup, maintaining detection accuracy and reducing false alarms over time.

Removable Detector Chamber

Enables easy maintenance and servicing without needing to replace the entire sensor.

Discreet and Durable Design

Features a modern, compact appearance that integrates seamlessly into any décor while offering robust protection.
