Product Overview

MSHA Approved for Use In Underground MinesThe CHECKFIRE MP-N (Mine Permissible) system meets MSHA approvals for use in underground mines (Permissible Applications in Explosive Methane/Air Applications). Built for equipment subjected to extreme environmental and physical conditions, the rugged system control module is designed to withstand shock and vibration and can be utilized as a self-contained system, powered by its own internal lithium battery. Additional system features include supervised circuitry, adjustable shutdown and discharge time delays.

Proven, Flexible Detection OptionsTwo detection options are available: Linear Detection Wire and Spot Thermal Detection.

The Linear Detection Wire consists of spring steel conductors that are separated by a heat-sensitive insulator that melts at 356°F (180°C), allowing the two conductors to make contact. This contact provides electrical continuity between the two conductors.

Spot Thermal Detectors are normally open, contact closure devices. The fixed temperature design causes the contacts to close when the temperature of the surrounding air reaches the set point temperature of the detector.
