Fire-Lite MS-10UD-7 10-Zone Conventional Fire Alarm Control Panel with 7A Power Supply

The Fire-Lite MS-10UD-7 is a 10-zone conventional fire alarm control panel with an integrated digital alarm communicator and 7-amp power supply, designed to provide dependable fire detection, notification, and system monitoring for small to medium-sized commercial, industrial, and institutional buildings. Manufactured by Fire-Lite Alarms, a Honeywell brand, the MS-10UD-7 combines conventional fire alarm zone monitoring with programmable notification control and off-premises alarm reporting. The panel provides 10 supervised Style B (Class B) initiating device circuits (IDCs) for connecting compatible two-wire and four-wire smoke detectors, heat detectors, manual pull stations, waterflow switches, supervisory switches, and other approved normally open initiating devices. It also includes four Style Y (Class B) notification appliance circuits (NACs) for operating compatible fire alarm horns, strobes, horn/strobes, bells, and other notification equipment. The MS-10UD-7 is supplied with an FLPS-7 power supply providing up to 7 amps of total 24 VDC system output current, making it suitable for facilities requiring multiple conventional detection zones and coordinated audible and visual notification.

The MS-10UD-7 incorporates 10 individually programmable initiating circuits, four configurable notification appliance circuits, and three programmable Form C relays for fire alarm, trouble, and supervisory functions. Each initiating zone can be configured for the appropriate detection or supervisory application, including alarm verification and Positive Alarm Sequence (PAS) where permitted. The panel supports System Sensor i3 Series smoke detectors, including compatible maintenance trouble and low-temperature supervisory signaling, allowing maintenance personnel to identify detector conditions requiring attention. Its four NACs provide a combined 7.0-amp output capacity, with a maximum of 3.0 amps per individual notification circuit, subject to the power supply and total system load limitations. Programmable NAC features include Temporal 3 signaling, steady output, silence inhibit, automatic silence, and selective audible silence for compatible horn/strobe arrangements. Built-in synchronization supports compatible System Sensor, Wheelock, Gentex, Faraday, and AMSECO notification appliances. Optional CAC-5X converter modules permit conversion of the initiating and notification circuits to Class A configurations, providing additional wiring flexibility for installations requiring enhanced circuit survivability.

The Fire-Lite MS-10UD-7 features an integrated 80-character backlit LCD display, membrane-style programming keypad, and dedicated system control buttons for local operation, configuration, and troubleshooting. Its front-panel controls include Acknowledge, Alarm Silence, System Reset/Lamp Test, and Drill functions, while individual LED indicators display fire alarm, supervisory, trouble, and AC power conditions. The controller maintains a 256-event history log with a real-time clock and calendar to support maintenance records, event investigation, and system diagnostics. An integrated dual-line Digital Alarm Communicator/Transmitter (DACT) supports communication with compatible central monitoring stations over conventional telephone connections, including Contact ID reporting and remote upload/download functions. Fire-Lite's PS-Tools programming utility allows authorized technicians to configure the panel and retrieve supported system information. The built-in ANN-BUS supports up to eight compatible annunciator and interface modules, including the ANN-80 remote LCD annunciator, ANN-LED zone annunciator, ANN-RLY relay module, ANN-I/O LED driver, and ANN-S/PG printer interface. These expansion capabilities allow the system to provide remote status indication, additional relay control, and enhanced operator access without replacing the main fire alarm control panel.

The MS-10UD-7 operates from a 120 VAC, 50/60 Hz primary power source and includes the FLPS-7 internal power supply, which delivers nominal 24 VDC operating power to compatible notification circuits and auxiliary equipment. The panel provides 500 mA of selectable resettable or non-resettable auxiliary 24 VDC power, supporting compatible four-wire smoke detectors and other approved peripherals within the total system power budget. An integrated charging circuit supports rechargeable sealed lead-acid standby batteries, with battery capacity selected according to the required standby and alarm durations. The system is supplied in a lockable metal enclosure with a 19-inch-high, 16.65-inch-wide, and 5.25-inch-deep backbox, providing space for the control board, power supply, field wiring, and compatible standby batteries. Optional accessories include the DP-51050 dress panel, TR-CE semi-flush trim ring, CAC-5X Class A converter modules, and remote ANN-BUS devices. The MS-10UD-7 is listed to UL 864, 9th Edition, for fire alarm control unit applications, with applicable FM and California State Fire Marshal approvals documented by the manufacturer. Designed for installation in accordance with NFPA 72 and applicable fire alarm codes, the panel combines 10 conventional detection zones, 7-amp notification power, integrated central station communication, programmable outputs, and remote annunciation capabilities for comprehensive fire alarm control in commercial and institutional facilities.
