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 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.

The Manufacturer recommends that smoke and/or heat detectors be located throughout a protected premise following the recommendations of the current edition of the National Fire Protection Association Standard 72 (NFPA 72), manufacturer's recommendations, State and local codes, and the recommendations contained in the Guide for Proper Use of System Smoke Detectors, which is made available at no charge to all installing dealers. A study by the Federal Emergency Management Agency (an agency of the United States government) indicated that smoke detectors may not go off in as many as 35% of all fires. While fire alarm systems are designed to provide early warning against fire, they do not guarantee warning or protection against fire. A fire alarm system may not provide timely or adequate warning, or simply may not function, for a variety of reasons:

Smoke detectors may not sense fire where smoke cannot reach the detectors such as in chimneys, in or behind walls, on roofs, or on the other side of closed doors. Smoke detectors also may not sense a fire on another level or floor of a building. A second-floor detector, for example, may not sense a first-floor or basement fire.

Particles of combustion or "smoke" from a developing fire may not reach the sensing chambers of smoke detectors because:

• Barriers such as closed or partially closed doors, walls, or chimneys may inhibit particle or smoke flow.

• Smoke particles may become "cold," stratify, and not reach the ceiling or upper walls where detectors are located.

• Smoke particles may be blown away from detectors by air outlets.

• Smoke particles may be drawn into air returns before reaching the detector.

The amount of "smoke" present may be insufficient to alarm smoke detectors. Smoke detectors are designed to alarm at various levels of smoke density. If such density levels are not created by a developing fire at the location of detectors, the detectors will not go into alarm.

Smoke detectors, even when working properly, have sensing limitations. Detectors that have photoelectronic sensing chambers tend to detect smoldering fires better than flaming fires, which have little visible smoke. Detectors that have ionizing-type sensing chambers tend to detect fast-flaming fires better than smoldering fires. Because fires develop in different ways and are often unpredictable in their growth, neither type of detector is necessarily best and a given type of detector may not provide adequate warning of a fire.

Smoke detectors cannot be expected to provide adequate warning of fires caused by arson, children playing with matches (especially in bedrooms), smoking in bed, and violent explosions (caused by escaping gas, improper storage of flammable materials, etc.).

Heat detectors do not sense particles of combustion and alarm only when heat on their sensors increases at a predetermined rate or reaches a predetermined level. Rate-of-rise heat detectors may be subject to reduced sensitivity over time. For this reason, the rate-of-rise feature of each detector should be tested at least once per year by a qualified fire protection specialist.

Heat detectors are designed to protect property, not life.

IMPORTANT! Smoke detectors must be installed in the same room as the control panel and in rooms used by the system for the connection of alarm transmission wiring, communications, signaling, and/or power. If detectors are not so located, a devel-

oping fire may damage the alarm system, crippling its ability to report a fire.

Audible warning devices such as bells may not alert people if these devices are located on the other side of closed or partly open doors or are located on another floor of a building. Any warning device may fail to alert people with a disability or those who have recently consumed drugs, alcohol or medication. Please note that:

• Strobes can, under certain circumstances, cause seizures in people with conditions such as epilepsy.

• Studies have shown that certain people, even when they hear a fire alarm signal, do not respond or comprehend the meaning of the signal. It is the property owner's responsibility to conduct fire drills and other training exercise to make people aware of fire alarm signals and instruct them on the proper reaction to alarm signals.

• In rare instances, the sounding of a warning device can cause temporary or permanent hearing loss.

A fire alarm system will not operate without any electrical power. If AC power fails, the system will operate from standby batteries only for a specified time and only if the batteries have been properly maintained and replaced regularly.

Equipment used in the system may not be technically compatible with the control. It is essential to use only equipment listed for service with your control panel.

Telephone lines needed to transmit alarm signals from a premise to a central monitoring station may be out of service or temporarily disabled. For added protection against telephone line failure, backup radio transmission systems are recommended.

The most common cause of fire alarm malfunction is inadequate maintenance. To keep the entire fire alarm system in excellent working order, ongoing maintenance is required per the manufacturer's recommendations, and UL and NFPA standards. At a minimum, the requirements of Chapter 7 of NFPA 72 shall be followed. Environments with large amounts of dust, dirt or high air velocity require more frequent maintenance. A maintenance agreement should be arranged through the local manufacturer's representative. Maintenance should be scheduled monthly or as required by National and/ or local fire codes and should be performed by authorized professional fire alarm installers only. Adequate written records of all inspections should be kept.

Installation Precautions

Adherence to the following will aid in problem-free installation with long-term reliability:

WARNING - Several different sources of power can be con- nected 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 this manual is read and understood.

CAUTION - System Reacceptance Test after Software Changes. To ensure proper system operation, this product

must be tested in accordance with NFPA 72 Chapter 7 after any programming operation or change in site-specific software. Reacceptance testing is required after any change, addition or deletion of system components, or after any modification, repair or adjustment to system hardware or wiring.

All components, circuits, system operations, or software functions known to be affected by a change must be 100% tested. In addition, to ensure that other operations are not inadvertently affected, at least 10% of initiating devices that are not directly affected by the change, up to a maximum of 50 devices, must also be tested and proper system operation verified.

This system meets NFPA requirements for operation at 0-49° C/32-120° F condensing) at 30° C/86° F. However, the useful life of the system's standby batteries and the electronic components may be adversely affected by extreme temperature ranges and humidity. Therefore, it is recommended that this system and all peripherals be installed in an environment with a nominal room temperature of 15-27° C/60-80° F.

Verify that wire sizes are adequate for all initiating and indicating device loops. Most devices cannot tolerate more than a 10% I.R. drop from the specified device voltage.

and at a relative humidity of 85% RH (non-

Like all solid state electronic devices, this system may operate erratically or can be damaged when subjected to lightning-induced transients. Although no system is completely immune from lightning transients and interferences, proper grounding will reduce susceptibility. Overhead or outside

aerial wiring is not recommended, due to an increased susceptibility to nearby lightning strikes. Consult with the Techni-

cal Services Department if any problems are anticipated or encountered.

Disconnect AC power and batteries prior to removing or inserting circuit boards. Failure to do so can damage circuits.

Remove all electronic assemblies prior to any drilling, filing, reaming, or punching of the enclosure. When possible, make all cable entries from the sides or rear. Before making modifications, verify that they will not interfere with battery, transformer, and printed circuit board location.

Do not tighten screw terminals more than 9 in-lbs. Over-tightening may damage threads, resulting in reduced terminal contact pressure and difficulty with screw terminal removal.

Though designed to last many years, system components can fail at any time. This system contains static-sensitive components. Always ground yourself with a proper wrist strap before handling any circuits so that static charges are removed from the body. Use static-suppressive packaging to protect electronic assemblies removed from the unit.

Follow the instructions in the installation, operating, and programming manuals. These instructions must be followed to avoid damage to the control panel and associated equipment. FACP operation and reliability depend upon proper installation by authorized personnel.

Product Description Product Features

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 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 resettable power. In addition, the MS-4 has a Form-C Supervisory relay and a nonresettable 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.

Operating Instructions Switch Functions in Normal Mode

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. Pressing the Acknowledge button will have no effect on the Notification Appliance Circuits. To activate, press and hold the Acknowledge button for a minimum of one second.

4.1.2 Silence

Pressing the Silence button, which is located on the FACP membrane switch panel, silences the system piezo sounder, turns off the silenceable Notification Appliance Circuits and turns on the Alarm Silence LED. The Silence button will be ignored for nonsilenceable waterflows and NACs. Upon the occurrence of a subsequent event (alarm or trouble), Silence is overridden and the control panel will respond to the new event. To activate, press the Silence button for a minimum of one second.

Note: If Silence Inhibit has been enabled, NACs cannot be silenced for one minute following initiation of an alarm.

4.1.3 Zone Enable/Disable

To disable a zone, press the corresponding Zone Enable/Disable button. The Zone Disable and system Trouble LEDs will blink, as well as the Trouble LED for the disabled zone. To enable the zone, press the Zone Enable/Disable button a second time.

4.1.4 Reset/(Lamp Test)

The system Reset button, which is located on the FACP membrane switch panel, resets the system and any smoke detectors. Each press of the Reset button will cause the following:

 Clear all status LEDs

 Turn off the Notification Appliance Circuits

 Reset all zones by temporarily removing power

 Silence the onboard piezo sounder

 Restore all system relays to normal

 Temporarily remove power from the resettable power output

Note: if Silence Inhibit is active, a panel reset cannot occur for one minute.

Any alarm, supervisory or trouble condition that exists after a system reset will resound the system, reactivating appropriate system activity. Any zones that were disabled before the reset will be disabled after the reset.

Lamp Test - When the Reset button is pressed and then released, the FACP will perform a Lamp Test. All panel LEDs will be turned on and the piezo will sound for approximately two seconds.

Page 39

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. Walktest can be exited by pressing and holding the Walktest button for a minimum of three seconds or by pressing the Reset button. Refer to “Walktest” for a complete description of this feature.

4.2 Walktest

Walktest allows the testing of all control panel IDCs (input zones). An audible or silent walktest may be performed.

It is important to note that while the FACP is in Walktest mode, the control panel is in

an off-normal condition and does not provide fire protection.

It should also be noted that the trouble relay will be activated while the control panel is in Walktest mode. Placing the control panel into Walktest mode will only be possible if the system has no active alarms.

Prior to initiating a walktest, check to make certain that all system faults have been cleared. Upon entering Walktest mode, the following conditions should occur:

• Trouble relay will activate

• Alarm relay will be disabled

• Supervision relay will be disabled (MS-4 only)

• Piezo sounder will be disabled

•I

smoke detectors will enter their own test mode causing their LEDs to flash

twice every five seconds (refer to the I

• All alarm conditions will be displayed as they occur by blinking zone alarm LED

• All zone troubles will be displayed as they occur by blinking zone trouble LED

specification document)

During walktest, the FACP zone LEDs will blink for the first activation on a zone. Subsequent activations on the same zone will cause the corresponding zone LED to blink the number of alarms on the zone since the start of the test, followed by a two second pause and then a repeat of the sequence.

Note that following a zone activation, a 6 second reset for conventional and 60 second reset for I

detectors is initiated. No new alarms or troubles will be detected during this

reset period.

Disabled zones will not respond during Walktest. A zone may be disabled while in Walktest mode, should a faulty device be detected. This allows the user to return the system to Normal mode, enabling all other zones while preventing the faulty zone from triggering a false alarm.

Audible Walktest

To perform an audible Walktest, press and hold the Walktest button for a minimum of two seconds. The Trouble and Walktest LEDs will blink at a ¼ second rate.

While testing input devices, the first initiating device activated on a zone will cause the NACs to sound for four seconds. Subsequent device activations on the same zone will cause the NACs to turn on for one second. Any smoke detectors that are activated will automatically be reset by the panel. Zone faults (open circuits) will cause the NACs to remain on steadily until the fault is cleared.

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.

Power Supply Calculations Overview

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 size of batteries required to support the system if an AC power loss occurs

4. Selecting the proper batteries for your system

5.2 Calculating the AC Branch Circuit

The control panel requires connection to a separate, dedicated AC branch circuit, which must be labeled FIRE ALARM. This branch circuit must connect to the line side of the main power feed of the protected premises. No other non-fire alarm equipment may be powered from the fire alarm branch circuit. The branch circuit wire must run continuously, without any disconnect devices, from the power source to the control panel. Overcurrent protection for this circuit must comply with Article 760 of the National Electrical Codes as well as local codes. Use 14 AWG (2.00 mm insulation for this branch circuit.

Use Table 5-1 , to determine the total amount of current, in AC amperes (A), that must be supplied to the system.

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 46. The control panel must support a larger load current during a fire alarm condition. To calculate the fire alarm load on the power supply, use Calculation Column 2 in Table 5-3 on page 46. The secondary power source (batteries) must be able to power the system during a primary power loss. To calculate the non-fire alarm load on the secondary power source, use Calculation Column 3 in Table 5-3 on page 46.

When calculating current draw and the battery size, note the following:

• ‘Primary’ refers to the main power source for the control panel

• ‘Secondary’ refers to the control panel’s backup batteries

• All currents are given in amperes (A). Table 5-2 shows how to convert milliamperes and microamperes to full amperes.

To convert... Multiply Example

Milliamperes (mA) to amperes (A)

mA x 0.001 3 mA x 0.001 = 0.003A

µA x 0.000001 300 µA x 0.000001 = 0.0003 A

5.3.2 How to Use Table 5-3 on page 46 to Calculate System Current Draw

Use Table 5-3 on page 46 to calculate current draws as follows:

1. Enter the quantity of devices in all three columns

2. Enter the current draw where required. Refer to the Fire-Lite Device Compatibility Document for compatible devices and their current draw

3. Calculate the current draws for each in all columns

4. Sum the total current for each column

5. Copy the totals from Column 2 and Column 3 to Table 5-4 on page 47

Following are the types of current that can be entered into Table 5-3 on page 46:

 Calculation Column 1 - The primary supply current load that the control

panel must support during a non-fire alarm condition, with AC power applied.

 Calculation Column 2 - The primary supply current load that the control

panel must support during a fire alarm condition, with AC power applied.

 Calculation Column 3 - The standby current drawn from the batteries in

a non-fire alarm condition during a loss of AC power.

Calculating the Battery Size Power Supply Calculations

5.4 Calculating the Battery Size

Use Table 5-4 to calculate the total Standby and Alarm load in ampere hours (AH). This total load determines the battery size (in AH), required to support the control panel under the loss of AC power. Complete Table 5-4 as follows:

1. Enter the totals from Table 5-3 on page 46, 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. Write the ampere hour requirements on the Protected Premises label located inside the cabinet door

5.4.1 NFPA Battery Requirements

• NFPA 72 Local, Central and Proprietary Fire Alarm Systems require 24 hours of standby power followed by 5 minutes in alarm

• NFPA 72 Auxiliary and Remote Station require 60 hours of standby followed by 5 minutes in alarm. Batteries installed in a system powered by a generator need to provide at least 4 hours of standby power

5.4.2 Selecting and Locating Batteries

Select batteries that meet or exceed the total ampere hours calculated in Table 5-4 . The control panel can charge batteries in the 7 AH to 18 AH range. The control panel cabinet is capable of housing batteries up to 7 AH. Batteries larger than 7 AH require the BB-17F or other UL listed external battery cabinet.
