Mircom CR-135-LED-MP Heat Detector

The Mircom CR-135-LED-MP is a moisture proof LED indicating heat detector designed for use in harsh environments where conventional smoke detection may be impractical. The Mircom CR-135-LED-MP combines rate-of-rise and fixed temperature detection with a highly visible LED indicator to provide dependable fire detection in areas exposed to humidity, condensation, dust, corrosive atmospheres, and wash-down conditions. Therefore, it is an excellent solution for industrial, commercial, and utility applications requiring reliable heat detection.

Mircom CR-135-LED-MP Function

The is designed to detect abnormal temperature increases and initiate a fire alarm condition. As a result, it provides early warning of developing fire events while reducing the risk of nuisance alarms often associated with smoke detectors in challenging environments. In addition, the detector incorporates both rate-of-rise and fixed temperature sensing technologies for enhanced fire detection performance.

Dual-Action Heat Detection

The CR-135-LED-MP utilizes a combination of rate-of-rise and fixed temperature detection methods. Consequently, the detector can activate when temperatures rise rapidly at approximately 15°F (8.4°C) per minute or when the ambient temperature reaches 135°F (57°C). Furthermore, this dual-action design provides faster response to rapidly developing fires while maintaining dependable fixed-temperature protection.

Moisture Proof Construction

The features a specialized moisture proof design intended for demanding environmental conditions. As a result, it is suitable for installation in areas with high humidity, condensation, corrosive elements, or frequent wash-down procedures. Additionally, the sealed construction helps protect internal components from environmental contamination that could affect detector performance.

Integrated LED Alarm Indication

The CR-135-LED-MP includes a highly visible LED indicator that provides local visual confirmation of detector activation. Therefore, maintenance personnel and emergency responders can quickly identify the initiating device during alarm conditions. Moreover, the LED indication simplifies testing, inspection, and troubleshooting procedures.

Designed for Harsh Environments

The Mircom CR-135-LED-MP is commonly installed in environments where smoke detectors may be susceptible to false alarms or contamination. Consequently, it is ideal for:

• Mechanical rooms
• Electrical rooms
• Transformer vaults
• Pump rooms
• Utility areas
• Storage facilities
• Manufacturing plants
• Parking structures
• Industrial processing areas
• Wash-down environments

These applications benefit from the detector’s ability to provide reliable heat detection despite challenging environmental conditions.

Non-Restorable Fixed Temperature Protection

The fixed temperature element utilizes a fusible mechanism designed to activate when the surrounding temperature reaches 135°F (57°C). As a result, the detector provides dependable thermal protection even if a fire develops without a rapid temperature rise. Furthermore, the non-restorable design ensures a positive alarm condition once the fixed temperature threshold is reached.

Fire Alarm System Compatibility

The CR-135-LED-MP is compatible with conventional fire alarm initiating circuits and can also be used with addressable systems through approved monitor modules. Therefore, it provides flexibility for both new construction and retrofit fire alarm installations. Additionally, the detector supports a variety of life safety applications requiring reliable heat detection in difficult environments.
