The MRP-2001C is a six-zone FACP for single and dual hazard deluge and preaction applications. The MRP-2001C provides reliable fire detection, signaling and protection for commercial, industrial and institutional buildings requiring water-based releasing. The MRP-2001C is compatible with System Sensor’s i3 detectors which are conventional smoke detectors that can transmit a maintenance trouble signal to the FACP indicating the need for cleaning and a supervisory ‘freeze’ signal when the ambient temperature falls below the detector rating of approximately 7.22°C. In addition, the control panel is compatible with conventional input devices such as two-wire smoke detectors, four-wire smoke detectors, pull stations, waterflow devices, tamper switches and other normally open contact devices.
