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 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 Guide for Proper Use
of System Smoke Detectors, which is made available at no
charge to all installing dealers. 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 detectors 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.
cated, 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 Chapter 7 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.

ADT-UZC-256 Universal Zone Coder
General
The ADT-UZC-256 Universal Zone Coder provides separate codes for up to 256 initiating
zones. Each code requires a different initiating circuit. Only one Notification Appliance
Circuit is required, but coded output from the ADT-UZC-256 can be fed to many output
circuits.
Coded Outputs
The ADT-UZC-256 contains three outputs, each rated for three amps at 30 VDC. These
outputs allow the ADT-UZC-256 to supply different coded information to certain output
circuits, depending on the alarm initiation condition. This can be useful when employing
coded outputs in floor-above, floor-below applications, or to provide various numbers of
rounds for bell circuits and strobe or lamp circuits.
These relays are controlled by a predefined program, and can be set to respond to general
alarm conditions with the fire alarm system. The ADT-UZC-256 also provides a second zonein-alarm override of the general alarm delay.
EIA-485 Communication
The ADT-UZC-256 and the CPU use the EIA-485 circuit for communication. When installed,
the zone coder automatically assumes the lowest available address on the EIA-485 interface.

sesserddA 1 1212 3 4
Assignment of points to zone codes within the ADT-UZC-256 is automatic in the Unimode
II and Unimode 4-16. It is programmable in the Unimode 2020/1010. Addresses occupied
by the ADT-UZC-256 are unavailable to other devices on the EIA-485 circuit (AMG,
annunciators, etc.).
Zone Code Protocol
The ADT-UZC-256 allows the specification of several parameters:
• Up to four code digits.
• Number of rounds
• Pulse-ON, Pulse-OFF time
• Time between digits
• Time between rounds
Note: Due to the nature of coded outputs, the ADT-UZC-256 is not compatible with
notification appliances which do not produce a steady sound. Periodic appliances that
produce their own code (such as some codes available with electronic sounders) will
not be compatible with the ADT-UZC-256; some appliances may have a response
time which is too slow to operate with the programmed code.

Unimode 2020/1010 Installation
Mechanical Installation
In a Unimode 2020/1010, the ADT-UZC-256 plugs into a slot on the ICA-4L chassis. If the
Unimode 2020/1010 is in an A-size cabinet (only one ICA-4L), the ADT-UZC-256 mounts
beneath the CPU or the SIB. If a second or third ICA-4L chassis is available, the
ADT-UZC-256 should be mounted in one of the two upper slots to permit easy access to
ADT-UZC-256 wiring and switch settings. Note that the ADT-UZC-256 mechanically
eliminates one LIB position, requiring the installation of an additional chassis in some
instances. As an alternative, the Unimode 2020/1010 may use a CHS-4 chassis to mount the
ADT-UZC-256 (see Figure 3 - 3).
Note also that the Unimode 2020/1010 does not require LIB boards to be installed in
consecutive positions. For example, in a five-loop system, the ADT-UZC-256 could be
installed in LIB position 3 (upper left of second chassis), with LIBs in all other slots. In this case,
the Unimode 2020/1010 would be programmed for loops 1, 2, 4, 5, and 6.
