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.

3.5 Input/Initiating Circuits

The ACC-25/50 Series 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 zero impedance to ground will cause a ground fault.

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

Coded.

Input and output terminals are provided for CMD1 and CMD2 to allow placement of the ACC25/50 Series 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 ACC-25/50 trouble condition (AC loss is programmable as described for switch 8 in Table 2.3 on page 34). This causes a NAC trou-

Section 5: Application Examples

The AUDIO•COMMAND•CENTER•25/50, AUDIO•COMMAND•CENTER•25/50ZS, and AUDIO•COMMAND•CENTER•25/50ZST are voice evacuation control panels which can be used, with a variety of Fire Alarm Control Panels, to provide emergency audio messages. This chapter contains a few application examples and is not meant to provide a comprehensive list of all possible ACC-25/50 Series applications.

5.1 One Speaker Circuit on ACC-25/50

Single Output Zone (Table 2.7 on page 37 for Message Control switch settings)

A very basic application consists of one ACC-25/50 Series with one amplifier and a single speaker circuit. This configuration is suitable for small facilities requiring no more than 25 watts of output power. A single fire evacuation message will be generated during an alarm condition from the host FACP or manually by a message push-button.

In this application, the NAC from the host FACP is connected to CMD1. The CMD1 out terminals are then terminated with an EOL resistor for the FACP's Style Y NAC or the terminals are wired back to the host FACP for a Style Z NAC. S3 DIP switches 1, 2 and 3 are set to OFF which causes a 60 second message to be sent to the speaker circuit when CMD1 input is activated. S5 DIP switch 5 is set to OFF which causes CMD1 input to be activated by a reverse polarity condition. CMD3, CMD4, and CMD5 inputs require End-of-Line resistors and CMD2 cannot be used to trigger the ACC-25/50.

IMPORTANT! When CMD1 is configured for reverse polarity, the NAC cannot

be Coded.

Audio•Command•Center•25/50 Connection to Multiple Audio•Command•Center•25/50 Distributed Audio Panels (see Table 2.7 on page 37 for Message Control switch settings and ACC-25/50DA Manual Doc. 52265).

This application consists of one ACC-25/50 and two ACC-25/50DA panels, supplying 150 watts of output power. The addressable FACP directs one of the five voice messages to both speaker circuits and also manages the routing of audio in the ACC-25/50DA panels via the control modules on the SLC Loop. Audio from the first amplifier of the ACC-25/50 is input to the ACC25/50DA via the audio riser.

The ACC-25/50 is configured for single zone operation by setting S3 DIP switches 1 and 3 to ON and DIP switch 2 to OFF. This causes CMD1 to activate the Fire Message, CMD2 to activate the Fire Alert Message, CMD3 to activate the Tornado Message, CMD4 to activate the Chemical Spill Message, and CMD5 to activate the All Clear Message. The FACP can route the message generated by the ACC-25/50 to the speaker circuits of the ACC-25/50DA by activating the control module connected to CMD1 of the ACC-25/50DA or it can select the ACC-25/50DA’s local message by activating the control module connected to CMD2.

All Call paging is possible by pressing the All Call button on the keypad of the ACC-25/50. This will activate the Master Command Bus and trigger the ACC-25/50DA speaker circuits. Keying the microphone will allow announcements to be made on all speaker circuits.

Section 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

The ACC-25/50, ACC-25/50ZS and ACC-25/50ZST require 1.5 amps from the AC branch circuit.

) wire with 600 volt insulation for this 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 6.3 . The ACC-25/50 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 6.3 .

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 Table 6.1 shows how to convert milliamperes and microamperes to full amperes

To convert.... Multiply Example

Milliamperes (mA) to

amperes (A)

Microamperes (µA) to

amperes (A)

Table 6.1 Converting to Full Amperes

mA x 0.001 3 mA x 0.001 = 0.003 A

µA x 0.000001 300 µA x 0.000001 = 0.0003 A

1. Enter the quantity of devices in both columns.

2. Enter the DC 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 both columns.

4. Sum the total current for each column.

5. Copy the totals from Column 1 and Column 2 to Table 6.3 on page 100.

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 Table 6.3 on page 100.

Power Supply Calculations 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-25/50 Series under the loss of AC power. Complete Table 6.3 as follows:

1. Enter the totals from Table 6.2 on page 99 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.
