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 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.

NOTE: The term DVC is used in this manual to refer to all DVC wire and fiber model versions.

Individual part numbers are used in this manual only to distinguish features or functions that differ. Available models are described in the DVC Digital Voice Command manual.

Refer to Figure 1.1 on page 9 for a simplified illustration of DAL devices on a digital audio loop.

NOTE:

Speaker placement must be given careful consideration when planning an audio system.

• Place speakers from different DALs (Digital Audio Loops) so they are not within the audible

areas of other DALs.

• Carefully consider the audible distance of speakers within a DAL; overlapping audio messages

can be confusing.



Batteries Outside the DAA2 Enclosure

When the batteries are installed outside the DAA2 cabinet, connections are the same as in Figure 2.9. However, the battery cables between the two enclosures must be in conduit and the enclosures must be within 20 feet (6.09 m) of each other within the same room.

Figure 2.10 Using Conduit

 Battery Sharing

Up to four DAA2s may share a set of batteries. When DAA2s share batteries

• the ground fault switch on the DAA2 power supply (SW1) must be set to “Disable” on all

but one DAA2 attached to the set of batteries.

• In VeriFire Tools programming, “Disable Charger” must be checked in the “DAA2

Amplifier Programming Service - General II” screen for all but one DAA2.

The enabled ground fault switch does not have to be on the same DAA2 as the enabled charger.

Connect all DAA2s sharing a set of batteries directly to the batteries using 12 AWG. If the batteries are located outside of the DAA2 cabinet, the wiring must be in conduit that is no greater than 20 ft (6.09 m) long.

Digital Audio Ports A and B, Wire Connections

Digital Audio Ports A and B (DAP A and DAP B) allow digital communication with the DVC over the Digital Audio Loop (DAL); Amplifier programming from the DVC; control, audio, trouble, address and firefighter telephone data; and live voice paging can be communicated through these ports. They may also act as repeaters, in that what is received at one port is transmitted out the other. Events generated at the DAA2 will be transmitted out both ports.

Figure 2.14 Wire the DAA2 Digital Audio Loop Connections

NOTE: Digital Audio Ports A and B must be wired in Style 4 or Style 7 configuration. Do not wire

them in bus configuration.

NOTE: Style 4 configuration must be installed in accordance with the requirements for survivability from attack by fire in the National Fire Alarm Code, NFPA 72.

Digital Audio Ports A and B, Fiber and Wire/Fiber Connections

DAA2 boards are wire, but may be converted partially or fully to fiber boards with the use of fiber option modules DS-FM and DS-SFM. (Refer to Section 5.3.1, “DAA2 Installation”, on page 77 for information on installing fiber option modules.) The fiber, or wire/fiber cabling between these ports provides a Digital Audio Loop (DAL) for programming; alarm, control, trouble, automatic audio messages, address and firefighter telephone data; and live voice paging communications.

Figure 2.15 illustrates an example of how a DAL can be formed using mixed wire and fiber connectors.

FFT Riser Connections

The Firefighter Telephone Riser connections (TB7) provide for the use of firefighter telephones (FFTs) on an analog network. They are a means of connecting various FFT telephone control modules and devices, such as FTM-1 modules, AFAWS, FPJ or RPJ-1 telephone circuits to the DAA2.

The FFT riser may be wired in NFPA Class A or Class B configuration. For trouble supervision, VeriFire Tools must be used to indicate whether a riser is installed or not. SW1 must be set to indicated whether the wiring is Class A or Class B. (Refer to page 41 for switch settings.) Class B 2-Wire configurations require a 3.9K ohm 1/2 watt end-of-line resistor (P/N R-3.9K). Class A 4wire configurations have an internal ELR and do not require an external ELR

There are two ways that firefighter telephones may be installed on a DAA2 FFT riser. Both configurations have a limit of seven active phones. (Refer to the FFT appendix in the DVC Digital Voice Command manual for more information on limits.)

1. “Install FTM” selected - FireFighter Telephones must be wired to the output of the FTM

modules. The telephone points will be SLC addresses.
