10 MS-2/MS-4 PN 51512:E 01/18/05
SECTION 1 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
3
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.
Note: Unless otherwise specified, the terms MS-2 and MS-4 are used in this manual to
refer to the MS-2 and MS-2E as well as the MS-4 and MS-4E FACPs respectively.
