CONVENTIONAL ( STANDARD) FIRE ALARM SYSTEM
Conventional Fire Alarm Systems, in their various forms, have been around for many of years and have
changed little in that time in terms of technology although design and reliability have impoved
significantly. However, Conventional systems are a well proven technology protecting many hundreds of
thousands of properties worldwide. A Conventional Fire Alarm System is often the natural choice for
smaller systems or where budget constraints exist.
In a Conventional Fire Alarm System the “Intelligence” of the system resides solely within the Fire Alarm
Control Panel. The panel receives a trigger signal from a Conventional Detector or Initiating Device
Circuit (Smoke, heat, flame detectors) which in turn signals the condition to the Notification (Indicating)
Device Circuit such as alarm sounders, horns, strobes and other remote signalling equipment.
Conventional detectors are normally connected to the Fire Control Panel via dedicated circuits, each
circuit protecting a designated “Zone” or area of the building. The system has different modes: Normal,
Alarm, Trouble, and others, depending on the Fire Alarm Manufacturer.

CONVENTIONAL FIRE ALARM CABLE SELECTION
The designer must be sure that the last device on the circuit has sufficient voltage to operate the device
within its rated voltage. When calculating the voltage available to the last device, it is necessary to oconsider the voltage drop due to the resistance of the wire. The larger the wire, the less the voltage drop.
Generally, for purposes of determining the wire size necessary for the system, it is best to consider all of
the devices as “lumped” on the end of the supply circuit, this simulates the worst case.
Typical wire size resistance:
18 AWG solid:
Approximately
16 AWG solid:
Approximately
14 AWG solid:
Approximately
12 AWG solid:
Approximately
6.5Ω/1000ft.
4.1Ω/1000ft.
2.6Ω/1000ft.
1.8Ω/1000ft.
Loop Resistance
13Ω/1000ft.
8.2Ω/1000ft.
5.2Ω/1000ft.
3.6Ω/1000ft.
EXAMPLE:
Assume you have 10 devices on a zone and each require 50mA average and 2000ft. of 14 AWG wiring.
The voltage drop at the end of the loop is .050 amps per device x 10 devices x 2.6Ω/1000ft x 2000 =
2.6 V. A 12 AWG would produce a drop 1.8 V, and a 18 AWG would produce a voltage drop of 6.5 V.
Notes:
• If Class A wiring is installed, the wire length may be up to 4 times the single wire length in this calculation
• Consult your panel manufacturer’s specifications to determine acceptable voltage drop. Do not exceed panels specified
amperage output
• All wiring must be installed in compliance with the National Electrical Code (NEC) and applicable local codes, as well as
special requirements of the authority having jurisdiction, using the proper wire size.

ADDRESSABLE FIRE ALARM SYSTEM
Addressable Fire Alarm Systems differ from conventional systems in a number of ways and certainly add
more flexibility, intelligence, speed of identification and scope of control. For this reason,
Addressable Fire Alarm Systems are the natural choice for larger premises and buildings with more
complex system requirements.
In an Addressable system, detectors are wired in a loop around the building with each detector having
its own unique address. The system may contain one or more loops depending upon the size of the system and design requirements. The Fire Control Panel communicates with each detector individually and
receives a status report e.g Normal, Alarm, Trouble etc. As each detector has an individual address the
fire alarm control panel is able to display or indicate the precise location of the device in question, which
obviously helps speed the location of an incident and for this reason zoning of the system is not necessary, although it may be done for convenience.
Addressable detectors are, in themselves, intelligent devices which are capable of reporting far more
than just fire or fault conditions. Most analog addressable detectors are able to signal if contamination in
the device reaches a pre-set level enabling maintenance to take place prior to problems being
experienced.
In most earlier styles of Addressable systems, the notification appliances were not intellegent. Today,
many manufacturers are providing addressable notification technology. There are many advantages of
providing such technology. Such as lower cost of wire, and overall installation time.

ADDRESSABLE FIRE ALARM CABLE SELECTION
The designer must be aware of not only the D.C Resistance of the cable, but the capacitance and the
Velocity of proporgation of the cable. The designer must assure that the overall loop capacitance is not
compromised, and error rates are kept to a minimum.
Nominal Capacitance for wire sizes:
18 AWG solid unshielded: 16pf/ft
18 AWG solid shielded:
25pf/ft
16 AWG solid unshielded: 18pf/ft
16 AWG solid shielded: 30pf/ft
14 AWG solid shielded:
30pf/ft.
12 AWG solid shielded:
35pf/ft.
Example
A systems loop capacitance is given to be
.5mf. A 16AWG shielded cable is selected.
45pf/ft **
54pf/ft **
54pf/ft **
63pf/ft **
** Capacitance between one conductor and the other connected to the shield.
Calculation:
.5 divided by .000054 = 9259ft.
if the system requirement is .2mf, then
.2 divided by .000054 = 3703ft.
Notes:
• If Class A wiring is installed, the wire length may be up to 4 times the single wire length in this calculation
• Consult your panel manufacturer’s specifications to determine acceptable loop capacitance.
• All wiring must be installed in compliance with the National Electrical Code (NEC) and applicable local codes, as well as
special requirements of the authority having jurisdiction, using the proper wire size.

LOW AND MID CAPACITANCE CABLES:
ADDRESSABLE FIRE ALARM SYSTEM
The need to conform to the American with Disability Act (ADA), and the increased demand for
addressable fire-alarm systems have created many changes in the fire-alarm cable constructions.
An addressable system allows the control panel or unit to communicate with each base individually
using a sophisticated polling process. The polling process allows the system to detect trouble, or alarm
or each base initiating devices, and in some cases the notification devices.
Addressable fire-alarm signals need to be fast and have a clear signal transfer. Hence the electrical
characteristics are a major concern in cable construction
OUTPUT

Minimal Capacitance change
Small capacitance change
Large capacitance change
Capacitance-The property of a system of conductors and dielectrics that allow the storage of an
electrical charge when a potential difference exists between conductors. Capacitance is found between
wo wires of a twisted pair, and also between adjacent conductors in the same cable (mutual capaciance). Capacitance is expressed in pf/ft. The larger the capacitance, the higher the distortions.
Velocity of propogation- refers to a ratio of a signal traveling through a cable compared to that same
signal traveling through air and is determined by the dielectric insulation material.

AQUASEAL WATER RESISTANT CABLE
Aquaseal Power-limited water-resistant cables are designed to be used for indoor/outdoor fire alarm system. The Aquaseal products are manufactured using a premium grade jacket compound. These cables
are flame retardant, sunlight and water resistant, and employ an abrasion and crush resistant construction. This durability allows the Aquaseal power-limited water-resistant cables to be direct burial.
The internal cable construction employs a dry water blocking barrier instead of a messy gel. Unlike
many other outdoor cables which can not be placed indoors due to their inability to pass flame tests.
Aquaseal water-resistant cables carry both indoor and outdoor ratings
Aquaseal cable retains consistent electrical characteristics compared to standard cable when immersed
in water. The moisture blocking barrier used in this cable has proven itself in various tests where standard outdoor cable has failed. This can be verified by monitoring the capacitance levels of both cables.
Aquaseal water-resistant cables will consistently have lower capacitance values and remain stable over
the long haul enabling the lowest signal loss.
Aquaseal is UL listed NEC type FPL or PLTC rated and utilizing 18 AWG to 12 AWG makes this cable
excellent for low voltage Conventional and Addressable systems.

SYSTEM LAYOUTS:
The initiating circuits that connect detectors to a control panel should be supervised so that a fault
(trouble) condition that could interfere with the proper operation of the circuit will be detected and annunciated.
Detectors are generally categorized as either 2-wire or 4-wire detectors. Two-wire detectors derive their
power directly from the same fire alarm control panel alarm initiating device circuit over which they report
an alarm. Because of their dependency on the initiating circuit, 2-wire detectors must be tested and listed for compatibility with the control panel to be used, to ensure proper operation.
Four-wire detectors are powered from a separate pair of wires, and like the 2-wire detector, apply an
electrical short across the associated alarm initiating device to transmit an alarm. Because they do not
derive their power from the alarm control panel circuit, compatibility is predicated upon the operating
parameters of the power supply to which the detectors are connected and not the initiating circuit.
Supervision of the power to 4-wire detectors is mandated through the use of an end of line power supervision relay (EOLR). When power is on, the relay contacts at the end of line relay are closed and connected in series with the end of line resistors beyond the last initiating device. Loss of power at any
point in the power supply circuit will cause the relay to de-energize and a trouble condition to occur on
the initiating circuit.
CLASS B CIRCUITS:
Class B circuits differentiate between short circuits across the loop ( alarm) and opens on the loop
(trouble). Supervision of this circuit is accomplished by passing a low current through the installation
wiring and an EOLR. Increases or decreases in this supervisory current are monitored by the fire alarm
control panel and will cause alarm or trouble conditions, respectively, to be indicated. A single onpen in
a Class B circuit disables all devices electrically beyond open.
CLASS A CIRCUITS
Class A circuits also differentiate between short circuits across the loop and opens on the loop.
Supervision is accomplished by monitoring the level of current passing through the installation wiring
and the EOLR, which in a Class A circuit is an integral part of the fire alarm control panel. Class A
wiring must return to and be terminated in the control panel. This technique requires a minimum of four
wires be terminated in the control panel, and further requires that the fire alarm control panel is
designed to monitor Class A circuits. The additional circuitry neccessary for Class A supervision
enables the control panel to “condition” the initiating circuit to monitor the initiating circuit from both ends
when in a trouble mode due to an open fault on the loop. This “conditioning” ensures that all devices are
capable of responding and reporting an alarm despite a single open or non-simultaneous single ground
fault on a circuit conductor.

Installation
Calculating Conduit Capacity
One Cable Type in Conduit
The following information is to provide you with a quick and easy reference for conduit fill
requirements. This information is to be used as a general guideline. Each installation has
different restrictions for installation environments and/or local codes to follow.
The Conduit Capacity Chart provided on the following page is for applications when only
one type of cable is to be used in a conduit. For example, if you know the diameter of the
cable you will be installing, use the cable O.D. column, and find the exact or next largest
diameter cable O.D.. Next, follow this row over to the number of cables you need to install
in a conduit. Then follow this column to the top of the chart and read the conduit size
required for the number of cables you need to install.
Multiple Types of Cable in One Conduit
If you will be mixing various cable diameters in a conduit, then this overall chart does
not apply. You will have to use the following guidelines to calculate the conduit fill
requirements.
To determine the conduit size required for a particular installation of cable follow
these steps:
1. Square the O.D. of each cable and total the results.
2. Multiply the total by .7854*. This is the total area of
the cables in square inches.
3. From the Permissible Area row on the Conduit
Capacity Chart shown on the following page, select the
conduit size with an area equal to or greater than the
total area you calculated.
* See Important Notes and
Installation Suggestions
** Permissible Area to be occupied (sq. in.) is based on the
NEC standard of 40% fill, which applies to three or more
non-lead covered cable installed in the same conduit.
• An anti-friction agent is recommended in pulling operations.
*CAUTION: Select an anti-friction agent which is suitable for the cable jacket material.
The electronic characteristics of unjacketed cable may change due to the
application of anti-friction agents.
* COLD ENVIRONMENT PRECAUTION: Due to the nature of PVC compounds to
become non-pliable when stored or handled in ambient temperatures of
32 degrees F or less, we recommend the following:
"Prior to installation, condition the cable for at least 24 hours
at room temperature to provide the best flex properties
for ease of installation."
• Permissible area chart does not apply to metallic and non-metallic surface raceways;
consult the NEC for recommendations.
THE NATIONAL ELECTRICAL CODE FORBIDS
THE INSTALLATION OF COMMUNICATION CABLE
IN THE SAME CONDUIT AS POWER CABLE.
Pulling Tensions
Under the stress of approximately 15,000 lbs./sq. in. annealed copper will begin to
permanently stretch. The table below lists the absolute maximum recommended pulling
tensions for conductor sizes. For multiple conductor cable, multiply the appropriate value
by the total number of conductors. These pulling tensions must be equally distributed
among the conductors.
THESE LIMITS MUST NEVER BE EXCEEDED
EVEN MOMENTARILY!
DON’T JERK THE CABLE!
The electronic characteristics of a cable may change due to
excessive tension and crushing.
Important Notes and
Installation Suggestions
• A single cable is permitted to occupy 53% and two cables are limited to 31% conduit
fill. For a single cable use .5927 in step 2, for two cables use 1.1034, and three
or more cables use .7854.
• This chart is based on the maximum number of cable permitted in conduit under the
B-I-A Vertriebs GmbH / Germany
Email: info@BiaGmbH.com
National Electrical Code, and is calculated on the area of the cable with 40% of the
conduit filled. For conduit runs of 50 to 100 feet, the installed number should be
reduced by 15%, or use the next larger size conduit. If more than two 90 degree
bends are to be used in the conduit run, or if the run is to be over 100 feet in length,
insert a pull box.

Important Note: This conduit capacity
chart is to be used as a general guideline.
Because local codes can vary from the
National Electrical Code, the manufacturer
cannot be held responsible for this information as it pertains to your installation. Proper
conduit fill is the sole responsibility of the
installer and it is your responsibility to see
that your installation will pass local codes.
* Permissible Area to be occupied (sq. in.) based on the NEC standard of 40% fill, which applies to three or more non-lead covered
cables installed in the same conduit.
