Firelite | MS-4

The Fire-Lite MS-4 is a conventional fire alarm control panel (FACP) designed to provide reliable fire signaling protection for small to medium-sized commercial, industrial, and institutional buildings. It supports four initiating device circuits (IDCs) and is compatible with a variety of conventional input devices. 

Key Features:

• Four Initiating Device Circuits (IDCs): Compatible with both two-wire and four-wire smoke detectors, pull stations, waterflow devices, tamper switches, and other normally open contact devices. 

• Two Notification Appliance Circuits (NACs): Each NAC supports built-in synchronization for System Sensor®, Wheelock®, or Gentex® devices, ensuring consistent operation of audio/visual notification appliances. 

• Advanced Maintenance Features: Includes drift compensation and maintenance alert capabilities to reduce false alarms and indicate when detectors require cleaning. Also provides a freeze warning feature to alert when ambient temperatures fall below detector ratings. 

• Optional Modules: Offers expansion options such as the 4XTMF transmitter module for municipal box transmitter and alarm/trouble reverse polarity, and the 4XZMF zone relay module for additional relay outputs. 

Specifications:

• Primary Power: 120 VAC, 50/60 Hz, 2.3 A.

• Total Usable Current: 3.0 amps, expandable to 6.0 amps with an optional second transformer.

• Dimensions: 14.5” (36.8 cm) H x 15.218” (38.65 cm) W x 2.875” (7.3 cm) D.

• Compatibility: Works with System Sensor’s i3 Series smoke detectors, providing features like EZ Walk Test and a remote maintenance signal without additional modules. 

The MS-4 is designed to meet the needs of various applications, offering flexibility and reliability in fire detection and notification. Its compatibility with a wide range of devices and optional modules allows for tailored configurations to suit specific requirements.
