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.
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 Guides for Proper Use of System Smoke Detectors, which are made available at no charge to all installing dealers. These docu­ments can be found at http:/www.systemsensor.com/html/ applicat.html. 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 stor-
age 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 developing 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 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 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 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 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 indoor dry operation at 0-49° C/32-120° F 93 ±2% RH (non-condensing) at 32 ±2° C/90 ±3° 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. Refer to manual Specifications section for maximum allowable I.R. drop from the specified device voltage.
and at a relative humidity of
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 Technical 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.
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
CHAPTER 1 Pr oduct Description
The AUDIO•COMMAND•CENTER•25/50DA Distributed Panel (ACC-25/50DA) and AUDIO•COMMAND•CEN­TER•25/50DAZS Zone System Distributed Panel (ACC-25/50DAZS) are single channel, 25 watt, 25 V gency voice evacuation panels which are designed to interface directly to the AUDIO•COMMAND•CENTER•25/50 (ACC-25/50) Series audio panels. The ACC-25/50DA Series, which supports up to eight speaker circuits, can be used to distribute voice evacuation audio over a building’s speaker system. The audio riser input provides automatic gain control (AGC) which compensates for any audio signal loss due to circuit loading or cable length, ensuring that a full output signal is delivered to the speakers. An optional FC-MGM message generator is available with standard pre-recorded message or programmable message capability (up to sixty seconds). An integral power supply with bat­tery charger supplies operational power. An ACC-AAM25 audio amplifier is provided standard with each base unit. An optional second ACC-AAM25 amplifier is also available for backup purposes or to provide an additional 25 watt speaker circuit. Optional 70 V
conversion modules are also available for installations where 70 V

CMD 1 and CMD 2 provide terminals for NAC input and output to allow instal lati on of the audio panel anywhere along the NAC circuit being used to activate it.
The ACC-25/50DAZS includes an ACC-ZPM Zone Page Module and an ACC-ZSM Zone Splitter Module. These modules provide up to eight speaker circuits that may be manually or automatically activated. Significant technolog­ical enhancements set the ACC-25/50DA Series apart from other voice panels. These enhancements include full supervision in both active (alarm or music) and standby conditions. Note: Music cannot be used for ACC-25/50DAZS. Supervision is provided for:
amplifier outputsfield wiring (shorts and opens)optional message generator (FC-MGM)all tone generatorsoptional remote microphone
If the audio riser input fails, the distributed audio panel can be programmed to switch to the built-in tone generator or optional FC-MGM Message Generator. If the FC-MGM fails or is not installed, the tone generators on the main circuit board can be automatically switched in as backups.
Power is fed independently
to each amplifier so that a short circuit in one amplifier will not shut down the other. Full output power of 25 watts per amplifier is generated while in a low battery condition. Power is not diminished when the optional 70 V
transformer module is installed. Audio is amplified utilizing modern integrated circuits as
RMS
opposed to transformer technology. This provides for very low signal distortion for crystal clear audio.
Primary applications for the audio panels include structures such as restaurants, schools, auditoriums, places of worship, buildings with occupancies over 50, etc. The ACC-25/50DA Distributed Audio Series is designed to interface directly to addressable or conventional fire alarm control panels or with the ACC-25/50 series audio control panels to distribute audio in systems that require more than 50 watts.

Operating Power
3.3 Operating Power
CAUTION: Several different sources of power can be connected to this panel. Disconnect all sources of power
!
before servicing. The panel and associated equipment may be damaged by removing and/or inserting cards, modules or interconnecting cables while this unit is energized. Also, many components are static sensitive which require the use of proper grounding techniques.
AC Power and Earth Ground Connection
Primary power source is 120 VAC, 50/60 Hz, 1.0 amp for the ACC-25/50DA. Overcurrent protection for this cir­cuit must comply with Article 760 of the National Electrical Code (NEC) and/or local codes. Make certain that the AC mains circuit breaker is off a pair of wires (with ground conductor) from the protected premises main breaker box to TB10 of the main circuit board. Use 14 AWG (1.6 mm O.D.) or heavier gauge wire with 600V insulation. No other equipment may be connected to this circuit and it may not contain any power disconnect devices. A separate Earth Ground connec­tion must be made to ensure proper panel operation and lightning and transient protection. Connect the Earth Ground wire (minimum 14 AWG) to one of the transformer mounting studs. Do not use conduit for the Earth Ground connection since this does not provide reliable protection.
Secondary Power Source (Batteries)
Observe polarity when connecting the batteries. Connect the battery cable to P11 on the main circuit board, using the plug-in connector and cable provided. The battery charger is current-limited and capable of recharging sealed lead acid type batteries (See Figure 3-5 for battery orientation). The charger shuts off when the system is in alarm. Refer to page 61 for calculation of the correct battery rating.
!
CAUTION: Battery contains sulfuric acid which can cause severe burns to the skin and eyes, and can destroy fabrics. If contact is made with sulfuric acid, immediately flush the skin or eyes with water for 15 minutes and seek immediate medical attention.
before making any wiring connections between the mains and the panel. Run

3.5 Input Circuits
3.5.1 Master Command Bus
The Master Command Bus Input circuit, when used with the ACC-25/50 Series, can be used to add paging flexibility. All field wiring for each circuit is power-limited and supervised for opens and ground faults. Note that zero imped­ance to ground will be indicated as a ground fault.
The Master Command Bus Input circuit is triggered by a reverse polarity signal such as the one from the Master Command Output Bus on the ACC-25/50 Series. Master Command input and output terminals are provided to allow connection to additional audio distribution panels.
When connecting the Master Command Output of ACC-25/50 Series to the Master Command Bus Input of distrib­uted audio panels, the wiring must be supervised by a 4.7K EOL resistor connected across the out terminals of Master Command Bus Output on the last panel.
In Example 1 illustrated below, the Master Command bus is activated during paging, which routes paging audio from the riser to the Distributed Audio Panel speakers.

Input Circuits
3.5.2 CMD Input Circuits
The Distributed Audio Panel has five Command Input circuits, which are used to activate the panel amplifiers which, in turn, transmit an audio signal over the system speakers. All field wiring for the circuits is power-limited and super­vised for opens and ground faults. Note that a ground fault is indicated when there is zero impedance to ground.
CMD1 and CMD2 Command Input circuits can be independently field programmed to be triggered by a contact closure or by the reverse polarity of a Notification Appliance Circuit. (IMPORTANT! When CMD1 and CMD2 are configured for reverse polarity, the NAC cannot be Coded). Input and output terminals are provided for CMD1 and CMD2 to allow placement of the Distributed Audio Panel anywhere along a Notification Appliance Circuit allowing nondedicated use of host FACP NAC for triggering. CMD1 has relay contacts (maximum current 2.0 amps) before the out terminals which will open the outgoing NAC circuit during a Distributed Audio Panel trouble condition. This causes an NAC trouble at the host FACP. Note that CMD1 and CMD2 configurations can be independently set so that both circuits are triggered by the same type of input or by different types of inputs (see Figure 3-8 on page 34).

Power Supply Calculations
CHAPTER 6 Power Supply Calculations
6.1 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
6.2 Calculating the AC Branch Circuit
The audio distribution 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 transponder. 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
2
) wire with 600 volt insulation for this branch circuit.
The ACC-25/50DA requires 1 amp from the AC branch circuit.
6.3 Calculating the System Current Draw
6.3.1 Overview
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 1 in Table 6-2 . The ACC-25/50DA must support a larger load current during a fire alarm condition and primary power loss. To calculate the fire alarm load on the secondary power source, use Calculation Column 2 in Table 6-2 .
When calculating current draw and the battery size, note the following:
• ‘Primary’ indicates that the audio panel is being powered by AC
• ‘Secondary’ indicates that the audio panel is being powered by battery backup during AC failure
• All currents are given in amperes (A) and refer to the DC shows how to convert milliamperes and microamperes to full amperes
TABLE 6-1: Converting to Full Amperes
To convert.... Multiply Example
Milliamperes (mA) to amperes (A)
Microamperes (µA) to amperes (A)
mA x 0.001 3 mA x 0.001 = 0.003 A
µA x 0.000001 300 µA x 0.000001 = 0.0003 A
current being supplied by the panel. Table 6-1
ACC-25/50DA 52265:B 1/30/08 61
Calculating the System Current Draw
6.3.2 How to use Table 6-2 to calculate system current draws
1. Enter the quantity of devices in both columns
2. Enter the DC current draw where required. Refer to the Device Compatibility Document for compatible
devices and their current draw
3. Calculate the current draws for each in both columns
4. Sum the total current for each column
5. Copy the totals from Column 1 and Column 2 to Refer to Table 6-3 on page 63
Following are the types of current that can be entered into Table 6-2 :
Calculation Column 1 - The standby current load that the audio panel must support (from the batteries)
during a non-fire alarm condition and a loss of AC power.
Calculation Column 2 - The alarm current draw that the audio panel must support (from the batteries)
during a fire alarm condition and a loss of AC power
Table 6-2 contains two columns for calculating current draws. For each column, calculate the current and enter the total (in amps) in the bottom row. When finished, copy the totals from Calculation Column 1 and Calculation Column 2 to Refer to Table 6-3 on page 63.

Calculating the Battery Size
6.4 Calculating the Battery Size
Use Table 6-3 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 ACC-25/50DA under the loss of AC power. Complete Table 6-3 as follows:
1. Enter the totals from Refer to Table 6-2 on page 62 Calculation Columns 1 and 2 where shown
2. Enter the NFPA Standby and Alarm times (refer to Section 6.4.1, 'NFPA Battery Requirements')
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 get the proper battery size (in AH)
5. Write the ampere hour requirements on the Protected Premises label located inside the cabinet door

Addressable Module Connections
Appendix B Addr essable Module Connections
When configured with an addressable FACP such as the MS-9200UD, MS-9200C(E) or MS-9600, the ACC-25/ 50DA may be triggered either by an FACP main NAC output or from addressable control modules. Figure B-1 illus­trates CMD1 triggered by an addressable control module. The addressable control module may trigger the ACC-25/ 50DA via reverse polarity (shown) or relay contact. The FACP monitors the ACC-25/50DA for faults while in the standby or alarm state by wiring a monitor module to the trouble contacts as shown in Figure B-1. Activation of the addressable control module is controlled by the FACP. Refer to the appropriate FACP manual for additional information.
