The MS-10UD-7(E) is a ten-zone FACP. This control panel provide reliable fire signaling protection for small to medium-sized commercial, industrial, and institutional buildings. The Panel include built-in communicators for Central Station Service and remote upload/download. The FACPs is compatible with System Sensor’s microprocessor-based i3 series detectors. These conventional smoke detectors 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. Additionally, both the MS-5UD-3 and MS10UD-7 are compatible with conventional input devices such as two- and four-wire smoke detectors, pull stations, waterflow devices, tamper switches, and other normally-open contact devices. Refer to the Fire•Lite Device Compatibility Document for a complete listing of compatible devices.
