MS-2/MS-4   PN 51512:E  01/18/05

Product Description

The MS-2 is a two zone FACP (Fire Alarm Control Panel) and the MS-4 is a four zone 
FACP.  The information in this manual refers to both the MS-2 and MS-4 unless 
otherwise specified.  These control panels provide reliable fire signaling protection for 
small to medium sized commercial, industrial and institutional buildings.  The FACP is 
compatible with System Sensor’s I

3

 detectors which are microprocessor-based 

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 (refer to System Sensor’s I

Installation and Maintenance Instructions document I56-1800-00 for device 
specifications).  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.  Refer to 
Fire•Lite Device Compatibility Document for a complete listing of compatible devices.

Outputs include one NAC (Notification Appliance Circuit) on the MS-2 and two NACs 
on the MS-4.  Each FACP has a Form-C Alarm and Trouble relay and 24 VDC special 
application resettable power.  In addition, the MS-4 has a Form-C Supervisory relay 
and a nonresettable special application power output. The FACP supervises wiring, AC 
voltage and battery level.

Activation of a compatible smoke detector or any normally-open fire alarm initiating 
device will activate audible and visual signaling devices, illuminate an indicating LED, 
sound the piezo sounder at the FACP, activate the FACP alarm relay and operate an 
optional module used to notify a remote station or initiate a auxiliary control function.  
The MS-2E and MS-4E offer the same features as the MS-2 and MS-4 but allows 
connection to 220/240 VAC.
