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 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 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 stor-

age 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. 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 this manual is read and understood.

CAUTION - System Reacceptance 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 indoor dry
operation at 0-49° C/32-120° F
93 ±2% RH (non-condensing) at 32 ±2° C/90 ±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 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. Refer to manual Specifications
section for maximum allowable I.R. drop from the specified
device voltage.

and at a relative humidity of

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
interferences, 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, and printed circuit board
location.

Do not tighten screw terminals more than 9 in-lbs.
Over-tightening 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 by authorized personnel.

Product Description

CHAPTER 1 Pr oduct Description

The 411UDAC is a fire alarm communicator with four input/channels and dual telephone lines. The four inputs use
conventional input devices. The 411UDAC accepts waterflow devices, two-wire smoke detectors, four-wire smoke
detectors, pull stations and other nor mally-open contact devices. The unit also supervises AC voltage, telephone line
input voltage/current, battery level and battery charger operation.

Outputs include one supplementary NAC (Notification Appliance Circuit), two programmable Form-C relays and 12
VDC resettable special application power. The 41 1UDAC interfaces with the public switched telephone network and
is compatible with most central station receivers. A total of fifteen popular communications formats are supported,
including the industry standard Ademco Contact ID. The communicator also contains a unique DACT option that

eliminates 'dialer runaway'. It restricts the transmission of any intermittent nuisance fault to 10 attempts in a 24 hour
period.

Accessories include the Fire-Watch 411 Series DACT Programmer (Model PRO-411) as well as the PK-411UD
Windows

®

95 based remote site programming software. The 411UDAC is supplied with a compact metal cabinet.

Panel Configuration

1.7 Panel Configuration

The 411UDAC can be configured, through programming, for the following modes of operation:

• Stand-alone Mode With Communicator Enabled - the 411UDAC functions as a latching digital alarm com­municator in which all input circuit activations latch (except those programmed as autoresettable) and are
restored only by pressing the local reset switch. The onboard communicator will attempt to transmit events to
a Central Station

• Slave Mode With Communicator Enabled - the 411UDAC functions as a nonlatching slave to a host control
panel and the onboard digital alarm communicator will attempt to transmit events to a Central Station

• Slave Mode With Communicator Disabled - the 411UDAC functions only as a nonlatching slave to a host
control panel. The digital alarm communicator will not transmit to a Central Station

1.8 Operational Modes

1.8.1 Normal Mode

Normal Mode is the standard mode of operation in which the 411UDAC monitors the channel/input circuits as well
as telephone line voltage and other internal circuits. In addition to locally annunciating system trouble, active chan­nel/input and communication fail, the onboard communicator transmits system status information to UL listed central
station receivers if programmed to do so. Transmitted data includes fire alarm, fire alarm trouble, supervisory alarm
and AC loss information. Specific digital communicator troubles are also transmitted.

1.8.2 Real Time Clock Mode

Real Time Clock Mode allows the user to change the digital alarm communicator’s internal 24 hour clock. Connect­ing an external Programmer allows access to the various Modes of operation. While the 411UDAC is in Real Time
Clock Mode, it does not monitor channel inputs.

1.8.3 Program Mode

Program Mode is used to change the programmed functions of the 411UDAC. While the 411UDAC is in Program
Mode, it does not monitor channel inputs. In addition, some program items will be locked, which will prevent editing
while the communicator is active (dialing, transmitting, etc.).

1.8.4 Troubleshoot Mode

Troubleshoot Mode may be used to sample and display status for all channel/input circuits, Notification Appliance
Circuit, AC power, battery, charger and 12 volt resettable power. In addition, Troubleshoot Mode may be used for
testing the telephone line interconnect wiring. Connection from the 411UDAC’s modular jacks, through the RJ31X
jacks and into the telephone network may be easily checked. In this mode, the Programmer keypad acts similar to a
telephone touchpad. While the 411UDAC is in Troubleshoot Mode, it does not monitor channel inputs.

1.8.5 Default Mode

Default Mode may be used to return all 411UDAC programming back to the factory default settings and to reset the
Real-Time Clock to ‘00:01’ midnight. See “Default Mode” on page 53.

Input Channels

2.4 Input Channels

The 411UDAC has four channel inputs. Channel/input field wiring is supervised for opens (trouble), shorts (alarm)
and ground faults (zero ohms impedance between panel and earth ground) by the 411UDAC. All conditions are visu­ally and audibly annunciated and, if programmed, communicated to a Central Station.

Each channel is a Style B (Class B) Initiating Device Circuit with the exception of channel/input 3 which can be con­figured for Style B or Style D (Class A). All inputs can be connected to normally-open contact type devices. In addi­tion, inputs 1 and 3 can be connected to conventional 2-wire smoke detectors. Refer to Figure 2-6, “Wiring Initiating
Device Circuits,” on page 24 for information on wiring Style B and Style D circuits.

The channel/inputs may be programmed as shown below:

• 2-wire smoke detector (inputs 1 & 3 only)

• Pull station

• Normally-open contact device

• Host panel trouble

• Supervisory

• Supervisory autoresettable

A maximum of five waterflow devices may be used on any circuit programmed as a waterflow zone per NFPA 72.

• Waterflow silenceable

• Waterflow nonsilenceable

It is allowable to mix an assortment of device types (i.e. smoke detectors, heat detectors, pull stations, etc.) on any
zone. This is not recommended, however, since specific and detailed reports will not be possible (particularly critical
when using Contact ID format). For example, the report of general fire alarm versus pull station fire alarm or smoke
detector fire alarm could not be distinguished.

411UDAC Document #51073 Rev. D 12/09/2008 P/N 51073:D 23

Input Channels

The factory default programming for each channel is as follows:

 Channel 1 - fire alarm (2-wire smoke)
 Channel 2 - pull station
 Channel 3 - fire alarm (2-wire smoke)
 Channel 4 - pull station

The following illustration shows Channel 1 connected to 2-wire smoke detectors, Channel 2 connected to manual pull
stations, Channel 3 connected to 2-wire smoke detectors and Channel 4 connected to waterflow devices. In this
example, the factory default programming for Channel 4 must be changed from pull station to waterflow device.
