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

In Riser Mode to RSM/AIM Series Canadian Room Isolator Modules

When a DAA2’s Riser Mode is programmed R

ISER MODE TO RSM/AIM SERIES MODULES (refer to

the DVC Digital Voice Command manual for programming), the amplified signal from the DAA2 is routed to RSM-1A or AIM-1A room isolator modules.

AIM-1A - Provides isolation to a separate circuit on an audio riser. A short circuit on an AIM-1A speaker circuit will not disable other speaker circuits on the riser.

RSM-1A - Works same as the AIM-1A, with the exception that there is a silence button for in-suite operation. The silence button will silence the audible signal to the module’s circuit for ten minutes during alarm. Resounding will occur automatically after ten minutes. To override the ten minute silence, CBE programming must be done at the FACP so that it interrupts the module’s 24VDC power for two seconds.

NFS2-3030 example:

Give the isolator module’s 24VDC source a common ground with the DAA2 amplifier. Power the isolator module through a relay module that has Special Zone 14 in its CBE list. Special Zone 14 will activate for ten seconds when a reset is initiated at the panel.This period is used to disable the 24VDC for those 10 seconds to clear a local silence.

Remove jumpers for speaker applications. (Refer to Figure 2.23.)

A pre-announce tone of 800 Hz will clear a local silence.

Do not use background music in this mode. The DAA2 will provide speaker circuit supervision only when idle.

NOTE: The DAA2-5070 speaker circuit risers are non power-limited when used with Canadian room isolator modules. Speaker Circuit 1 can not be used with these modules. All DAA2-5025 and DAA2-7525 speaker circuit risers are power-limited when used with Canadian room isolator modules.

 Speaker Backup Circuits - TB1, TB14, TB15, TB16

The DAA2 supports one-to-one or one-to-many backup amplifier applications. A BDA-25/70V backup amplifier may be used in a one-to-one backup application. Refer to “BDA Backup Digital Amplifiers” on page 67 for information on the BDA-25/70V amplifier. Each DAA2 must be designated a primary or backup amplifier through VeriFire Tools programming. The speaker wiring from backup to primary is unsupervised when the backup amplifier is not active; therefore the backup and primary amplifiers must be in the same enclosure, or in conduit within the same room.

Figure 2.26 One-to-one Backup Using BDA-25/70V

Each backup terminal block contains two sets of terminals. One set may be used for “Backup In” applications, the other set for “Backup Through” applications..

NOTE: In Style 4 wiring arrangements of the DAL (digital audio loop), it is recommended that the backup amplifier be located closer to the DVC than the primary DAA2 amplifiers on the DAL.

Each DAA2 acts as a repeater for the digital audio signal. If a primary amplifier falls off-line, the backup will not receive the signal if it is further down the DAL chain.

2.3 DAA2 Configuration

2.3.1 Setting the Configuration Switches

GND Fault Switch - SW1 on CPS-24

The DAA2 has a ground fault switch that can be set to EN (enable) to detect ground faults on the board’s external wiring (except DAL Port A) and on a DAL (digital audio loop) segment (Port B). Port A is isolated, and ground fault detection on Port A will be performed at the other end of the connection. A general ground fault error for the device will be generated when a ground fault is detected.

The default state of the switch is for Earth Fault detection to be disabled. When sharing batteries, only one Earth Fault detection circuit can be enabled. When batteries are not shared, each Earth Fault detection circuit must be enabled.

Refer to “Battery Sharing” on page 27, as well as the DAL Earth Fault Detection appendix in the DVC Digital Voice Command manual for more information on how to set this switch.

2WIRE/4WIRE Switch - SW1 on DAA2 Board

The FFT riser may be wired in a Class A four-wire or a Class B two-wire configuration.

Address Switches - SW2, SW3

A maximum of 32 digital audio loop devices may be connected to one DVC. Each device must have its own address. Refer to Figure 2.32 for an illustration of address settings and to Figure 2.3 on page 19 for the location of the switches.

Addresses one (1) through 32 may be used for digital communication. Address 00 and addresses above 32 will generate a DAA2 trouble.

The default address setting for the DAA2 as it arrives from the factory is 00.

AC Power

WARNING: High Voltages Present.

Use extreme caution when working with the DAX. High voltage and AC line-connected circuits are present. Turn off and remove all power sources. To reduce the risk of electric shock, make sure to properly ground the board.

The DAX requires connection to a separate dedicated AC branch circuit. Follow these guidelines when connecting the AC branch circuit:

• Label the branch circuit “Fire Alarm”.

• Connect the branch circuit to the line side of the main power feed of the protected premises.

• Do not power other equipment from the fire alarm branch circuit.

• Run the AC branch circuit wire continuously, without any disconnect devices, from the power source to the power supply.

• Overcurrent protection for the AC branch circuit must comply with Article 760 of the National Electrical Codes, as well as local codes.

• Use 12-14 AWG (1.6mm O.D.) wire with 600 VAC insulation for the AC branch circuit.

Connect primary power as follows:

1.Turn off the circuit breaker at the main power distribution panel.

2.Connect the earth ground terminal (TB7 EARTH) to a solid earth ground (a metallic, cold water pipe may be suitable in some installations). This connection is vital to maintaining the power supply’s immunity to unwanted transients generated by lightning and electrostatic discharge.

3.Connect the primary power neutral line to the terminal marked NEUTRAL and the primary power AC line to the terminal marked HOT.

(refer to the DVC Digital Voice Command manual for programming), the amplified signal from the DAX is routed to RSM-1A or AIM-1A room isolator modules.

AIM-1A - Provides isolation to a separate circuit on an audio riser. A short circuit on an AIM-1A speaker circuit will not disable other speaker circuits on the riser.

NFS2-3030 example:

Give the module’s 24VDC source a common ground with the DAX amplifier. Power the isolator module through a relay module that has Special Zone 14 in its CBE list. Special Function Zone 14 will activate for ten seconds when a reset is initiated at the panel. This period is used to disable the 24VDC for those 10 seconds to clear a local silence.

Remove jumpers for speaker applications. (Refer to Figure 3.18.)

 Speaker Backup Circuits - TB10 and TB 11

The DAX supports one-to-one or one-to-many backup amplification. A BDA-25/70V backup amplifier may be used in a one-to-one backup application. Each DAX must be designated a primary or backup amplifier through VeriFire Tools programming. The speaker wiring from backup to primary is unsupervised when the backup amplifier is not active; therefore the backup and primary amplifiers must be in the same enclosure, or in conduit within the same room.

Each backup terminal block contains two sets of terminals. One set may be used for “backup in” applications, the other set for “backup through” applications.

NOTE: In Style 4 wiring arrangements of the DAL (digital audio loop), it is recommended that the backup amplifier be located closer to the DVC than the primary DAX amplifiers on the DAL.

Each DAX acts as a repeater for the digital audio signal. If a primary amplifier falls off-line, the backup will not receive the signal if it is further down the DAL chain.

 One-to-One Backup Using BDA-25/70V

Figure 3.21 shows the installation of a BDA-25/70V backup digital amplifier onto the primary amplifier. Should the amplifier portion of the DAX fail, all its messages will still be played by the BDA as programmed.

 One-to-One or One-to-Many Backup Using DAX

BKUP1and BKUP2 terminals on the DAX may be used to connect a backup amplifier to one or more primary amplifiers.

NOTE: Each backup terminal block contains two sets of terminals. One set may be used for “Backup In” applications, the other set for “Backup Through” applications.

One backup DAX may be used to back up as many as 31 primary DAX amplifiers. All primary amplifiers backed by the same backup amplifier must each be wired in the same style or combination of styles; for example, all wired Class A, or all wired Class B, or all wired with one Class A and two Class B circuits.

3.3 DAX Configuration

3.3.1 Setting the Configuration Switches

EARTH FAULT (Switch 5) - DAX-35 Only

The DAX-35 has a ground fault switch that can be set to EN (enable) to detect ground faults on the board’s external wiring (except DAL Port A) and on a DAL (digital audio loop) segment (Port B). Port A is isolated, and ground fault detection on Port A will be performed at the other end of the connection. A general ground fault error for the device will be generated when a ground fault is detected.

Refer to the DAL Earth Fault Detection appendix in the DVC Digital Voice Command manual, as well as “Battery Sharing” on page 53, for more information on how to set this switch.

Address Switches

A maximum of 32 DAL devices may be connected to one DVC. Each device must have its own address. Refer to Figure 3.26 for an illustration of address settings and to Figure 3.2 on page 47 for the location of the switches.

Addresses one (1) through 32 may be used for digital communication. Address 00 and addresses above 32 will generate a DAX trouble.

The default address setting for the DAX as it arrives from the factory is 00.

3.3.2 Programming

The DAX is programmed through VeriFire Tools. Refer to the DVC Digital Voice Command manual as well as the VeriFire Tools CD and Help file for information on how to create, prioritize and download audio messages, create system equations for message distribution, and set system parameters.

3.4 DAX Operation

3.4.1 Volume

The volume of audio messages is determined through FACP/network annunciator progrmaming and VeriFire Tools Read Status Service Form.

3.4.2 Trouble Messages

DAXs will send trouble messages to the DVC through the wire or fiber DAL (Digital Audio Loop). The DVC in turn sends them to the panel or network annunciator. Refer to the System Troubles appendix in the DVC Digital Voice Command manual for a list and description of system troubles.

Section 5: Fiber Option Modules

The DVC-PCC and all other DAL devices except fiber DAA amplifiers support wire media as shipped. The use of fiber optic media requires the use of fiber option modules. Each DAL device can be used with either one or two modules. This flexibility allows for the creation of digital audio networks with mixed wire, multi-mode fiber, and single-mode fiber segments on the same loop.

Fiber option modules consist of the following models:

Model Fiber Type For direct fiber connection between.... Not Used on

DS-FM multi-mode Two DAL devices Single or multi-mode DVC-

PCA, DVC-PCB or DAA.

DS-SFM single-mode Two DAL devices. An ST® style connector is

required at a single-mode DVC/DAA end.

DS-RFM multi-mode Two DAL devices, one of which is a multi-mode

fiber DVC or DAA. An ST® style connector is required at the multi-mode DVC/DAA end.

Table 5.1 Fiber Option Module Models

NOTE: Whenever a fiber option module is used on a DAL device port, the next DAL device that

is linked to that port must have the same model fiber option module (with the exception of singleand multi-mode DVCs and DAAs).

Multi-mode DVC-PCA, DVC-PCB or DAA.

Single-mode DVC-PCA, DVC-PCB or DAA.

One or two fiber option modules may be connected to a DAX or DAA2 board to convert it from a board with two wire DAP ports to:

• a board with one wire and one fiber port,

• a board with two single-mode fiber ports,

• a board with two multi-mode fiber ports, or

• a board with one single-mode and one multi-mode fiber port.

When a fiber option module is mounted on a DAA2 or DAX, it disables the corresponding wire terminals.

• DAA2: TB2 (Digital Audio Port A) is disabled when a fiber option board is connected at J9. TB3 (Digital Audio Port B) is disabled when a fiber option board is connected at J10.

• DAX: TB1 (Digital Audio Port A) is disabled when a fiber option board is connected at J2. TB2 (Digital Audio Port B) is disabled when a fiber option board is connected at J3.

Attenuation of cabling between two nodes (fiber-optic circuits are point-to-point) must not exceed the maximum attenuation, specified below.

To determine attenuation:

1. Find the rated dB loss per foot within the cable manufacturer’s specifications. Determine

the total attenuation between the two nodes due to the cable. Loss = (loss/ft.) x (length in feet)

2. Establish the dB loss for each connector and splice. Sum all the losses.

3. Total the attenuation factors obtained in steps 1 and 2. This will provide an approximate

attenuation total. The actual attenuation should be measured end-to-end with fiber-optic industry standard equipment.

DS-FM and DS-SFM

The maximum attenuation:

6.5dB for multi-mode with 50/125 micrometer cable @ 1310 nm. 10dB for multi-mode with 62.5/125 micrometer cable @ 1310 nm. 30dB for single-mode with 9/125 micrometer cable @ 1310 nm.

DS-SFM/Single-mode fiber DVC/DAA Connection

The maximum attenuation:

17dB for single-mode with 9/125 micrometer cable at 1310 nm going from the DS-SFM to the fiber DVC or fiber DAA. 4dB for single-mode with 9/125 micrometer cable going from the fiber DVC or fiber DAA to the DS-SFM

The minimum attenuation:

12dB going from the DS-SFM to the fiber DVC or fiber DAA.

DS-RFM/Multi-mode fiber DVC/DAA Connection

Attenuation going from the fiber DVC or fiber DAA to the DS-RFM:

2dB maximum for multi-mode with 50/125 micrometer cable @ 850 nm for the

DS-RFM.

4dB maximum for multi-mode with 62.5/125 micrometer cable @ 850 nm for

the DS-RFM.

Attenuation going from the DS-RFM to the fiber DVC or fiber DAA:

12dB minimum*, 16dB maximum for both cable types.

*If the length of the fiber run results in an attenuation of less than 12dB, a suitable

attenuator must be used.

C.1 Overview

C.1.1 Description

The DAA Digital Audio Amplifiers are multi-featured amplifiers with digital audio functionality. They are designed for a networked or non-networked environment with the DVC Digital Voice Command.

DAA models are compatible with other types of DAL devices (e.g. DAA2, DAX) on a wire, fiber, or mixed wire/fiber digital audio loop. A DS-RFM (for multi-mode DAAs) or DS-SFM (for singlemode DAAs) is required for a fiber DAA used on a DAL with other types of DAL devices.

NOTE: The term DAA is used in this manual to refer to all the model versions listed in the bullets below this note. Individual part numbers are used to distinguish features or functions that differ.

To determine attenuation:

DAA2 & DAX — P/N 53265:A1 8/24/2011 91

DAA Digital Audio Amplifiers Overview

1. Find the rated dB loss per foot within the cable manufacturer’s specifications. Determine

the total attenuation between the two nodes due to the cable. Loss = (loss/ft.) x (length in feet)

2. Establish the dB loss for each connector and splice. Sum all the losses.

3. Total the attenuation factors obtained in steps 1 and 2. This will provide an approximate

attenuation total. The actual attenuation can be measured end-to-end with fiber-optic industry standard equipment using a test wavelength of 850 nanometers (multimode)/1300 nanometers (single-mode).

The Maximum attenuation*:

4.2dB for multi-mode with 50/125 micrometer cable @ 850 nm. 8dB for multi-mode with 62.5/125 micrometer cable @ 850 nm.

5.0dB for single-mode with 9/125 micrometer cable @ 1300 nm.
