Fire Alarm Control Panel MS-2 & MS-4 MS-2E & MS-4E Instruction Manual Document 51512 10/18/2011 Rev: P/N 51512:G2 G2 ECN 11-740
Fire Alarm System Limitations While a fire alarm system may lower insurance rates, it is not a substitute for fire insurance! An automatic fire alarm system—typically made up of smoke detectors, heat detectors, manual pull stations, audible warning devices, and a fire alarm control panel with remote notification capability—can provide early warning of a developing fire. Such a system, however, does not assure protection against property damage or loss of life resulting from a fire.
Installation Precautions Adherence to the following will aid in problem-free installation with long-term reliability: WARNING - Several different sources of power can be connected to the fire alarm control panel. Disconnect all sources of power before servicing. Control unit and associated equipment may be damaged by removing and/or inserting cards, modules, or interconnecting cables while the unit is energized. Do not attempt to install, service, or operate this unit until manuals are read and understood.

Section 3: Program Options via DIP Switch This section describes the programming options available via DIP switch settings. The FACP can be field programmed using option DIP switches SW1, SW2, and SW3 which are located in the bottom right side of the main circuit board. A factory-installed dip switch cover, which prevents accidental programming, must first be removed. Once programming is complete, the cover must be reinstalled.
DIP Switch Settings Program Options via DIP Switch 3.1 DIP Switch Settings The following tables list the programmable features for the MS-2 and MS-4. Placing a DIP switch in the ON position will select the feature while placing the DIP switch in the OFF position will deselect the feature. The exceptions to this rule are SW3 DIP switches 5 & 6. These two switches are used to select the Notification Appliance Circuit synchronization feature.
Program Options via DIP Switch Switch Number SW1 SW2 SW3 DIP Switch Settings DIP Switch Number DIP Switch ON 1 Silence Inhibit 2 Auto-silence 3 Temporal Coding 4 Selective Silence (if sync.
DIP Switch Settings Program Options via DIP Switch 3.1.1 SW1 DIP Switch Settings Silence Inhibit Switch 1, placed in the ON position, selects the Silence Inhibit feature. This feature prevents the silencing or resetting of the NACs (Notification Appliance Circuits) for a period of one minute after initiation of an alarm. Placing switch 1 to the OFF position deselects the Silence Inhibit feature. The factory default setting is switch 1 OFF for no Silence Inhibit.
Program Options via DIP Switch DIP Switch Settings IDC Combination Circuit Switch 8, placed in the ON position, sets IDC #1 on the MS-2 or IDC #2 on the MS-4 as a combination circuit. A combination zone can be used for monitoring supervisory devices such as valve tamper switches and alarm devices such as waterflow switches. Supervisory conditions, which latch via software, can be silenced by pressing the Acknowledge and then Silence buttons.
DIP Switch Settings Program Options via DIP Switch IDC1 Supervisory for MS-2 or IDC2 Supervisory for MS-4 Switch 4, placed in the ON position, programs IDC #1 on the MS-2 or IDC #2 on the MS-4 as a Supervisory circuit. A supervisory zone can be used for monitoring supervisory devices such as sprinkler tamper switches. A supervisory activation will pulse the piezo sounder at a ½ second rate and flash the zone supervisory LED at the same rate. The factory default setting is switch 2 OFF for no Supervisory.
Program Options via DIP Switch DIP Switch Settings NAC2 Disable (MS-4 only) Switch 4 only on the MS-4, placed in the ON position, will disable NAC #2, preventing the notification appliances from activating. This feature may be used during maintenance or while testing the system to prevent building evacuation. The FACP will indicate an NAC disabled fault and system trouble while this feature is selected. The factory default setting is switch 4 OFF for NAC2 enabled.

Section 4: Operating Instructions The MS-2 and MS-4 have two modes of operation which are Normal and Walktest modes. Upon initial power-up, the system will be in Normal Mode. This section discusses operation of the control panel in the Normal Mode. 4.1 Switch Functions in Normal Mode 4.1.1 ACK - Acknowledge The Acknowledge button, which is located on the FACP membrane switch panel, silences the system piezo sounder and changes all flashing system LEDs to on steady.
Walktest Operating Instructions 4.1.5 Walktest The Walktest button, which is located on the FACP membrane switch panel, allows a panel walktest to be performed. Pressing and holding the Walktest button for a minimum of two seconds causes the FACP to enter audible walktest. Pressing the Walktest button and then the Silence button and holding both for a minimum of two seconds will cause the panel to enter silent walktest.
Operating Instructions Status LEDs During an audible walktest, if a device remains latched in alarm (such as a Pull Station that is not reset after activation), subsequent testing of devices on the same zone will not trigger the NACs. Be certain to reset or clear each device after testing. Silent Walktest To perform a silent Walktest, press the Walktest button, then press the Alarm Silence button and hold both for a minimum of two seconds.
Operation Operating Instructions Zone Fire Alarm LED A red LED for each zone that blinks to indicate that an alarm exists on the corresponding zone. It turns on steady when the Acknowledge or Alarm Silence button is pressed. Zone Supervisory LED A yellow LED for each zone that blinks if the zone has been programmed for supervisory and a supervisory condition exists on the corresponding zone. It turns on steady when the Acknowledge or Alarm Silence button is pressed.
Operating Instructions Operation 4.4.

Section 5: Power Supply Calculations 5.1 Overview This section contains instructions and tables for calculating power supply currents in alarm and standby conditions. This is a four-step process, consisting of the following: 1. Calculating the total amount of AC branch circuit current required to operate the system 2. Calculating the power supply load current for non-fire and fire alarm conditions and calculating the secondary (battery) load 3.
Calculating the System Current Draw Power Supply Calculations 5.3 Calculating the System Current Draw 5.3.1 Overview The control panel must be able to power all internal and external devices continuously during the non-fire alarm condition. To calculate the non-fire alarm load on the system power supply when primary power is applied, use Calculation Column 1 in Table 5.3 on page 48. The control panel must support a larger load current during a fire alarm condition.
Power Supply Calculations Calculating the Battery Size Table 5.3 contains three columns for calculating current draws. For each column, calculate the current and enter the total (in amperes) in the bottom row. When finished, copy the totals from Calculation Column 2 and Calculation Column 3 to Table 5.4 on page 49.
Calculating the Battery Size Power Supply Calculations 1. Enter the totals from Table 5.3 on page 48, Calculation Columns 2 and 3 where shown. 2. Enter the NFPA Standby and Alarm times (refer to ‘NFPA Requirements’ below). 3. Calculate the ampere hours for Standby and Alarm, then sum the Standby and Alarm ampere hours. 4. Multiply the sum by the derating factor of 1.2 to calculate the proper battery size (in AH). 5.
