Fire Alarm System Limitations

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 detectors 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.).

While a fire alarm system may lower insurance rates, it is not a substitute for fire insurance!

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.

detectors are designed to protect property, not life.

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 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.

CAUTION -

Changes.

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 RH (non-condensing) at 30° 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.

ACM-16ATF/ACM-32AF Manual PN 51480:A0 02/02/01

1. Product Overview

This manual provides instructions for connecting an ACM-16ATF series and ACM-32AF series annunciators to various Fire Alarm Control Panels. Each appendix contains instructions that are unique to a particular FACP.

General

This series provides Fire•Lite FACPs with up to 32 remote serially connected annunciators, each with a capacity of 64 points, for a total capacity of 2048 points. Expander modules are provided for each series.

The series provides an array of LEDs to indicate, at a remote location, the status of circuits within the system. Individual fire alarm control panels offer different methods of identifying annunciator points:

• Sensiscan 200 and Sensiscan 2000 - Annunciator points directly

follow the circuit arrangement of modules installed in the cabinet.

• MS-9200 and MS-9600 - Annunciator points are programmable by

group.

Common system functions such as signal silence, system reset, and local annunciation controls (local acknowledge and lamp test) are controlled through the annunciator's integral membrane push switches.

Communication between the control panel and the modules is accomplished over a power-limited, two-wire serial interface employing an EIA-485 communication standard. Power for the modules is provided via a separate power-limited power loop from the control panel which is inherently supervised by the annunciator module (loss of power results in an communication failure at the control panel). The module can also be powered from a power-limited and regulated remote power supply listed for fireprotective signaling use.

3. Design Considerations

Limits

The standard Fire•Lite EIA-485 circuit can drive up to 32 annunciators or expanders. The number of annunciators that can engage in two-way communication is dependent on the number of addresses available with a given fire alarm control panel. The actual number of annunciator/expander modules that can be powered in a particular system depends on the current available from the control panel’s power supply.

Note: Refer to the instruction manual of the particular Fire Alarm Control Panel for more details.

Wire Runs

Communication between the control panel and the annunciator occurs over a power-limited 2-wire EIA-485 serial interface. This communication is supervised by the fire alarm control panel. Each annunciator/expander module also requires a filtered 24 VDC power connection. This power circuit is inherently supervised; loss of power registers as a communication failure at the control panel.

The EIA-485 circuit cannot be T-Tapped; it must be wired in a continuous fashion. The maximum wiring distance is 6,000 feet at 16 AWG. The wiring size must be a 12 AWG to 18 AWG twisted shielded pair cable having a characteristic impedance of 120 ohms, +/- 20%. Limit the total wire resistance to 100 ohms on the EIA-485 circuit, and 10 ohms on the annunciator power circuit. Do not run cable adjacent to, or in the same conduit as, 120 volts AC service, “noisy” electrical circuits that are powering mechanical bells or horns, audio circuits above 25 volts RMS, motor control circuits, or SCR power circuits.

3. Design Considerations Receive Only and Transmit/Receive

Receive Only and Transmit/Receive

For redundant annunciation of system points, annunciators can be configured as “Receive Only” annunciators. Receive Only annunciators must be set to the same address as the annunciators they duplicate. Receive Only annunciators intercept information being transmitted to a “Receive/Transmit” annunciator for duplication at an intermediate display location. When configured for Receive Only operation, they cannot be used to send information to the system, and as a result are not supervised by the control panel. They cannot perform remote functions such as Acknowledge, Silence, or Reset. Control switches on Receive Only annunciators can be used only for local functions, such as Lamp Test. Wiring to Receive Only annunciators may be supervised by installing the modules “upstream” of fully supervised, Receive/Transmit annunciators along the EIA-485 line.

Annunciators that are configured to serve as full function annunciators can both receive status information as well as transmit commands to the control panel. This allows the annunciator to remotely execute functions of the control panel in addition to displaying the status of the system.

Annunciator Power Requirements

Annunciators draw their power from the control panel and must be considered when calculating the primary and secondary power supply requirements for the system. Each annunciator module is accounted for in the power calculations outlined in the respective installation manual. However, if the current draw dedicated to the annunciators must be calculated as a separate figure, use the equations below:

Number of ACM modules [ ] X 0.040 = [ ] amps

Note: The 0.040 amps can be reduced to 0.030 for modules with Piezo Disable or Flash Inhibit modes selected.

For 10% capacity, enter 10% of the total number of ACM and AEM modules multiplied by the number of remote annunciator locations, but do not enter less than one.

Total Annunciator Alarm Current = [ ] amps
