Commercial Fire Alarms


The Fire-Lite MS-5UD five zone, and MS-10UD ten zone Fire Alarm Control Panels bring the latest in technology to conventional fire controls.The MS-5UD and MS-10UD are fully programmable via built-in keypad and 80 character LCD display, so you do not need an external programmer. Both panels have a built-in Digital Alarm Communicator Transmitter (DACT) and availability to add optional equipment: Remote annunciator, Relay module, LED Driver module, Transmitter module and Printer interface module. Both panels are compatible with the new i3 smoke detectors from System Sensor, providing such advanced features as drift compensation, maintenance alert, and freeze warning – features normally found in more expensive addressable systems.

The Notification Appliance Circuit (NAC) protocol includes the ability to silence audible devices while strobes continue to flash, using only a single pair of wires, as well as automatic synchronization for five manufacturer’s synchronization protocols of audio/visual devices. The panels are also 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.


When coupled with the Fire-Lite MS-5UD and MS-10UD Fire Alarm Control Panels, i3 devices provide additional detection technology. i3 detectors automatically adjust their sensitivity settings based on dust accumulation in their chamber, resulting in an increased resistance to false alarms. A special maintenance alert message on each zone will warn of excessive dirt accumulation preventing false alarms – a quick way to test each detector without need for a ladder. In addition, a special supervisory message warns if a detector is approaching freezing temperatures. This is especially useful when panels are placed in a warehouse facility where such low temperatures may be found. A special wireless handheld sensitivity meter eliminates the need for voltmeters, magnets and physical connections to the detectors to determine sensitivity settings. The meter displays sensitivity in terms of percent per foot obscuration and provides status of detector sensitivity in clear English text.


The MS-5UD and MS-10UD panels provide state-of-the-art NAC synchronization features that meet NFPA requirements for both audible signals and ADA MS-5UD/MS-10UD Conventional Fire Alarm Systems Advanced systems ideal for small facilities compliant strobes. To ease retrofit applications, strobe synchronization is provided for System Sensor, Wheelock, Amseco, Faraday and Gentex signaling protocols, and permits use of existing devices. Both panels contain a Selective Silence feature where horns can be manually silenced while strobes continue to flash on the same NAC. This reduces confusion when first responders arrive to survey the situation, yet still warns occupants to exit the building.


Designed to reduce installation and maintenance labor time, both panels feature a Silent or Audible Walk Test operation
mode that can be commanded from the front keypad. If no activity takes place after one hour, the system automatically returns to normal operation. To further reduce false alarm potential, the systems feature the ability to select alarm verification mode by each zone. This permits testing of zones that may be more prone to alarm to insure the detectors have not sensed a false indication of fire. When using the MS-5UD, a special module is available that converts all five indicating circuits and notification appliance circuits to be used in a Class A wiring configuration, enhancing wire supervision for opens or shorts. When low-cost conventional fire detection equipment is required and budget is tight, you can rest assured the advanced features found in the MS-5UD or MS-10UD will meet and exceed requirements for the most demanding applications. The MS-5UD and MS-10UD are

designed and built by Fire-Lite Alarms, well known throughout
the industry for high quality and exceptional design.
