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 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 first­floor 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 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 panel. 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 manuals are read and understood.
CAUTION - System Re-acceptance 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 operation at 0-49º C/32-120º F and at a relative humidity 93% ± 2% RH (non­condensing) at 32°C ± 2°C (90°F ± 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 its peripherals be installed in an environment with a normal room temperature of 15-27º C/60-80º 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.
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 interference, 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, or printed circuit board location.
Do not tighten screw terminals more than 9 in-lbs. Over­tightening 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.

Section 1: Product Description

The ACC-25/50 Series consists of the AUDIO•COMMAND•CENTER•25/50 (ACC-25/50), the AUDIO•COMMAND•CENTER•25/50 Zone System (ACC-25/50ZS), and the AUDIO•COM­MAND•CENTER•25/50 Zone System with Telephone (ACC-25/50ZST) which are single channel, 25 watt, 25 VRMS, emergency voice evacuation panels. The ACC-25/50 provides up to two speaker circuits while the ACC-25/50ZS and ACC-25/50ZST support up to eight speaker circuits. Each panel provides the ability to record five field programmable messages (up to 60 seconds total message duration) with an integral microphone or from an external audio source. 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 channel of 25 watts. Optional 70 VRMS con­version modules are also available for installations where 70 VRMS speakers are to be installed or already exist. An optional External Page Module (ACC-EPM) is available for interfacing to nonfire paging systems. The modular design allows for ease-of-serviceability.
Automatic activation of the ACC-25/50 by an FACP is possible via the five Command Input Cir­cuits (CMD). The ACC-25/50ZS and ACC-25/50ZST can be automatically activated by the CMD inputs or via the ACS serial communications link from the MS-9600, MS-9200UDLS, MS­9200UD, MS-9200(E) and MS-5210UD FACPs.
Two Command Input Circuits can be independently field programmed for activation by an FACP Notification Appliance Circuit reverse polarity or by closure of a supervised normally open contact and three Command Input Circuits activate on contact closure. CMD 1 and CMD 2 provide termi­nals for NAC input and output to allow installation of the audio panel anywhere along the NAC cir­cuit being used to activate it. Options via the Command Inputs allow one 60 second message, two 30 second messages, three 20 second messages, four 15 second messages or five 12 second mes­sages.
The ACC-25/50ZS and ACC-25/50ZST include an ACC-ZPMK Zone Page Module with keypad and an ACC-ZSM Zone Splitter Module. These modules provide up to eight speaker circuits that may be manually or automatically activated.
The ACC-25/50ZST includes an ACC-FFT Fire Fighter Telephone Module with keypad which provides indications of phone activation, remote page activation, remote microphone activation and corresponding trouble conditions. Additionally, up to 24 telephone circuits can be annunciated at the ACC-FFT by connecting addressable monitor modules to the optional FPJ-F or RPJ-F Remote Page Jacks.
Significant technological enhancements set the ACC-25/50 Series apart from other voice panels.
These enhancements include full supervision in both active (alarm or music) and standby condi­tions. Supervision is provided for:
amplifier outputs
field wiring (shorts and opens)
message generator
all tone generators
microphone
telephones (optional)
If the message generator fails, the system automatically reverts to the primary tone generator. If the primary tone generator fails, one of three backups become enabled.
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
RMS
is amplified utilizing modern integrated circuits as opposed to transformer technology. This pro­vides for very low signal distortion for crystal clear audio.

1.4 Circuits

Input Circuits - CMD1, CMD2, CMD3, CMD4 & CMD5
Input circuits CMD1 and CMD2 are independently field programmable to accept Notification Appliance Circuits or normally open contacts. (IMPORTANT! When CMD1 and CMD2 are
configured for reverse polarity, the NAC cannot
feed-through of the NACs, allowing placement of the ACC-25/50 Series anywhere along a Notification Appliance Circuit. A trouble on the ACC-25/50 Series will cause relay contacts at the out terminals of CMD1 to open, causing an NAC circuit trouble at the FACP.
NOTE: The ACC-25/50 Series will not open the out terminals while in alarm or during AC loss if the Trouble Relay is programmed not to transfer on AC Loss conditions (refer to Switch 8 in Table
2.3 on page 34). Monitoring ACC-25/50 Series troubles while in alarm requires use of
independent trouble relay at TB1.
Programming CMD1 and/or CMD2 for activation on contact closure will allow activation of the amplifiers on a normally open contact transfer to the closed condition. Contact wiring is supervised for open conditions. A short will cause amplifier activation (contact closure).
Input circuits CMD3, CMD4 and CMD5 will only activate on contact closure which will allow activation of the amplifiers on a normally open contact transfer to the closed condition. Contact wiring is supervised for open conditions.
Audio Input Jacks
RCA Jack provides convenient connection to an audio source such as a tape player for recording a new digital message. It may also be used for background music if approved by local AHJ. Background music is prohibited during AC loss conditions to preserve battery power.
PC Jack provides convenient connection to an audio source such as a personal computer for recording a new digital message. The jack allows vertical plug-in of a standard mini-jack cable. It may also be used for background music if approved by local AHJ. Background music is prohibited during AC loss conditions to preserve battery power.
Output Circuits
Specific Application Power Output, 35 mA @ 24 VDC.
Main circuit provides a 24 Volt Battery Charger (up to 18 AH batteries) @ 800 mA maximum.

The FC-MIM module function is incorporated into the ACC-FFT module eliminating the need for the FC­MIM (refer to Section “ACC-FFT Fire Fighter Telephone Module (ACC-25/50ZST Only)” on page 55.
ACC-EPM External Page Module
Connector P13 provides a connection for the optional ACC-EPM External Page Module which is used to connect external non-emergency page equipment. The electrically isolated signal from the external equipment is not supervised by the ACC-25/50 Series panels. Alarm condition and paging from the ACC-25/50 Series panels have priority and will override all external page functions. To preserve battery power, non-emergency paging is prohibited during AC loss conditions.
ACC-ZPMK Zone Page Module (ACC-25/50ZS & ACC-25/50ZST only)
Connector P11 provides a connection for the ACC-ZPMK Zone Page Module which is used to annunciate and control the selection of speaker circuits. Refer to Section “ACC-ZPMK Zone Page Module - ACS Link (ACC-25/50ZS & ACC-25/50ZST)” on page 52.
