Fire Alarm & Emergency Communication System Limitations

While a life safety system may lower insurance rates, it is not a substitute for life and property
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 (FACP) 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.

An emergency communication system—typically made up
of an automatic fire alarm system (as described above) and a
life safety communication system that may include an autono­mous control unit (ACU), local operating console (LOC), voice
communication, and other various interoperable communica­tion methods—can broadcast a mass notification message.
Such a system, however, does not assure protection against
property damage or loss of life resulting from a fire or life
safety event.

The Manufacturer recommends that smoke and/or heat
detectors be located throughout a protected premises
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. This document can be found at
http://www.systemsensor.com/appguides/. 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,
chimneys, even wet or humid areas 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, such as air conditioning vents.

• 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,
compromising its ability to report a fire.

Audible warning devices such as bells, horns, strobes,
speakers and displays 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:

• An emergency communication system may take priority
over a fire alarm system in the event of a life safety emer­gency.

• Voice messaging systems must be designed to meet intelli­gibility requirements as defined by NFPA, local codes, and
Authorities Having Jurisdiction (AHJ).

• Language and instructional requirements must be clearly
disseminated on any local displays.

• 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 to or comprehend
the meaning of the signal. Audible devices, such as horns
and bells, can have different tonal patterns and frequen­cies. It is the property owner's responsibility to conduct fire
drills and other training exercises 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 life safety 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
premises 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 life safety system malfunction is
inadequate maintenance. To keep the entire life safety system

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 . 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.

When the AMPS-24 communicates via the SLC, the installer must reserve sequential SLC
addresses (an address block) equal to the number of addresses that will be consumed by the
AMPS-24. Determining the size of the address block and setting the SLC base address is
described in this section.

3.1.1 Determining Address Consumption

CAUTION:

Always select “SLC Trouble Reporting” when connecting the AMPS-24 to an NFS2-3030.

Software determines the AMPS-24 address consumption. An AMPS-24 can occupy either one or
five addresses on an SLC. The AMPS-24 will consume five addresses on the SLC if configured for
five-point trouble reporting. If trouble reporting is not selected, the AMPS-24 will only consume
one address. Table 3.1 details address consumption.

3.1.2 Setting the Base Address (SLC Enabled)

The base address is the first address used in an SLC address block. Combine rotary switch (SW2)
and address switch (SW3) settings to determine the base address (B). The base address will be a
number that ends in zero or five and the rest of the address block will progress sequentially from
that number until all the addresses in the block are consumed.

NOTE: The lowest base address for the AMPS-24 is 05. Do not use FACP addresses 00 through 04
for the AMPS-24.

The Rotary Switch

The rotary switch SW2 determines the address decade. Each number on the dial represents the ten
addresses of a decade. Turning the arrow until it points at a number selects that number’s decade.

For example:

Pointing the arrow at the 1 selects the “one” address decade, beginning at 10.

Pointing the arrow at the 12 selects the “twelve” address decade, beginning at

120.

The SLC Address Slider Switch (SW3)

Use the slider switch, SW3, to further define the SLC base address. While an address’ decade is
defined by the rotary switch, the slider determines whether the base address (B) will end in a zero
or a five. Sliding the switch towards the 0 selects a base address that ends with a zero. Sliding the
switch towards the 5 selects a base address that ends with a five.

For example:

Slide the switch towards the 0, as shown in the illustration to the left, to select
an initial address that ends in zero. Since the rotary switch defines the decade, if
the rotary switch were to point at 8, the base address in this address block would
be 80.

Slide the switch towards the 5, as shown in the illustration to the left, to select
an initial address that ends in five. Since the rotary switch defines the decade, if
the rotary switch were to point at 8, the base address in this address block would
be 85.

3.3 Configuring the Network Annunciator

3.3.1 Programming

Because the AMPS-24 communicates with an NCA-2 through the use of 485 trouble reporting, it
does not require an SLC address block. Supervision and addressing for the AMPS-24 is assigned at
the network annunciator. Note that the AMPS-24 can connect to the NCA-2 via TB1 (dedicated
connection) or TB3 (remote connection) on the AMPS-K2 board.

See the NCA-2 manual for more information.

3.3.2 Display

When the power supply is configured for 485 Trouble Reporting, the NCA-2 displays a system

Section 4: Power Supply Calculations

Calculations must be done to determine standby and alarm DC current loads. Ampere-hour
requirements must be calculated as well to determine battery size.

The AMPS-24 provides filtered 24VDC (nominal) power that may be used for operating external
devices. The power for operating external devices is limited. Use Table 4.1 to determine if external
loading is within the capabilities of the power supply.

4.1 Calculating the System Current Draws

When used as the main power supply, the AMPS-24 must be able to power all internal system
devices (and several types of external devices) continuously during non-fire alarm conditions. Use
column 1 in Table 4.1 to calculate the Non-Fire Alarm Load on the power supply when applying
primary power. The main power supply must also provide a finite amount of additional current
during a fire alarm condition. Use column 2 in Table 4.1 to calculate the additional current needed
during fire alarms. The requirements for non-fire alarm and fire alarm current loads cannot exceed
the capabilities of the power supply as listed below.

4.1.1 How to Use the Calculating Tables

In the following section, the term “secondary” refers to the AMPS-24’s backup batteries: the term
“primary” is reserved for the AMPS-24’s primary source of power, 120 VAC 50/60 Hz power
(240 VAC 50/60 Hz for the AMPS-24E). The term “standby” refers to the output current required
when no fire alarm is present. The term “alarm” refers to the output current required when a fire
alarm is present.

The Primary Non-Fire Alarm Current and Fire Alarm Current columns are DC current calculations.
Use these calculations to confirm that the AMPS-24 can provide enough current to support the
system during Primary Non-Fire Alarm and Fire Alarm conditions.

Quantities List the number of devices powered by the MAIN 24V Main Output (TB1), AUX 24
Output (TB3), and the AUX 24V Accessories Output (TB2 on the CPS-24). Devices powered by
the Accessories Outputs draw current directly from the AMPS-24. Devices powered by the Main
Output draw current through the fire panel’s connection to the power supply. Use these quantities to
calculate total current draw of each set of devices in calculation columns 1, 2, and 3.

Calculation Column 1 (Primary, Non-Fire Alarm Current in amps) Add the contents of
Column 1 to get the current drawn from the AMPS-24 during a non-fire alarm condition, with AC
power applied. See Section 2.7.1.

Calculation Column 2 (Primary, Fire Alarm Current in amps) Column 2 lets the system
designer determine the current load that the AMPS-24 must support during a fire alarm. See
Section 2.7.1.

Typically, a system should contain capacity to activate all output circuits and relays, and support
fire alarms on no less than 10% of Initiating Device Circuits, subject to the requirements of the
Authority Having Jurisdiction (AHJ).

If the system provides power for Notification Appliance Circuits, refer to the Device Compatibility
Document for 24 VDC notification appliances that are UL/ULC-listed for fire alarm systems.

Calculation Column 3 [Secondary (Battery) Non-Fire Alarm Current] Column 3 lets
the system designer calculate the non-fire alarm current drawn from the secondary source in a non­fire alarm condition during AC power loss. The non-fire alarm current is required to complete the
standby battery calculations. After summing all current draws, insert the total in Table 4.2.

Table 4.1 System Draw Current Calculations

* Devices powered by the Main Output (MAIN 24, TB1) draw current through the fire panel’s connection to the power supply.
† Value represents an SLC’s maximum current draw. Refer to device datasheets for individual current draws. Total device current cannot exceed 200mA.
‡ Current consumption of the DPI-232 is dependent upon the baud rate selection (via slide switch on the DPI-232). See DPI-232 manual for details.
** Refer to manual and/or Device Compatibility Document.
†† Refer to Table 1.1, “Output Current for Each Configuration,” on page 8 to determine the maximum current for your configuration.

Calculating the System Current Draws Power Supply Calculations

4.1.3 Calculating the Maximum Secondary Power Non-Fire Alarm Current Draw

Use the table below to determine the maximum current requirements of the secondary power
source during non-fire alarm conditions. The result obtained is the amount of current that the
batteries must be able to supply to the fire alarm system. Use the result in Table 4.4 to determine the
size of the batteries needed for the fire alarm system.

Results taken from the table below assume that, while in a non-fire alarm condition, batteries must
feed the AMPS-24 (and any additional supplies) with the maximum rated power each supply can
provide.

Table 4.4 Secondary Power Standby and Fire Alarm Load

The following notes apply to Table 4.4:

1. NFPA 72 Local, Proprietary, Central Station, Auxiliary and Remote systems requires 24 hours
of standby power followed by 5 minutes in alarm.

2. Older NFPA standards and certain jurisdictions require 60 hours or standby power followed by
5 minutes in alarm. Verify this requirement with the AHJ.

3. Batteries installed in a system powered by an automatic starting engine generator need to
provide at least 4 hours of standby power.

4. Factory Mutual requires 90 hours of standby for deluge-preaction systems.

5. Emergency voice/alarm communications systems require 2 hours of operation in the alarm
condition. Due to the sporadic nature of voice operation, however, NFPA 72 permits 15
minutes of operation at a maximum connected load to equal 2 hours of normal use.

6. If the total exceeds 200 AH, an Uninterruptable Power Supply with sufficient amp-hour
capacity is needed. The Uninterruptable Power Supply must be UL-listed for Fire-Protective
Signaling.

7. The following battery derating factors must be used for Canadian installations using an
AMPS-24 charger:

• For 7 AH capacity, use derating factor of 1.1

• For 12 AH capacity, use derating factor of 1.2

• For 26 AH capacity, use derating factor of 1.2

• For 55 AH capacity, use derating factor of 1.8

• For 100 – 200 AH capacity, use derating factor of 2.5
