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 NFP A 72 af ter any programming operation or change in site-specific
software. Re-acceptance 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 within the range of 0°C-49°C (32°F-120°F) or humidity within the range
of 10%-93% at 30°C (86°F) noncondensing. 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. Remove DC power 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. Over-tightening may
damage threads, resulting in reduced terminal contact pressure and difficulty with
screw terminal removal. Fire alarm control panels contain 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 (Fire Alarm Control Panel) operation and reliability
depend upon proper installation.
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. The most common cause of fire alarm malfunctions, however, is inadequate maintenance. All devices
and system wiring should be tested and maintained by professional fire alarm
installers following written procedures supplied with each device. System inspection
and testing should be scheduled monthly or as required by national and/or local fire
codes. Adequate written records of all inspections should be kept.

Introduction
Limitations of Fire Alarm Systems
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
Guide for the 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 or give early warning in as many as 35% of all fires. While fire alarm
systems are designed to provide 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. For example:
•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.
In general, smoke detectors on one level of a structure cannot be expected to sense
fires developing on another level.
•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 photo electronic 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 are subject to false alarms and nuisance alarms and may have
been disconnected by users. For example, a smoke detector located in or near a
kitchen may go into nuisance alarm during normal operation of kitchen
appliances. In addition, dusty or steamy environments may cause a smoke
detector to falsely alarm. If the location of a smoke detector causes an abundance
of false alarms or nuisance alarms, do not disconnect the smoke detector; call a
professional to analyze the situation and recommend a solution.
•Smoke detectors cannot be expected to provide adequate warning of fires caused
1514501-3
Model 5600 Installation and Operation Manual
by arson, children playing with matches (especially within bedrooms), smoking in
bed, violent explosions (caused by escaping gas, improper storage of flammable
materials, etc.).
•Heat detectors do not sense particles of combustion and are designed to alarm
only when heat on their sensors increases at a predetermined rate or reaches a
predetermined level. Heat detectors are designed to protect property, not life.
•Warning devices (including horns, sirens, and bells) may not alert people or wake
up sleepers who are located on the other side of closed or partially open doors. A
warning device that activates on a different floor or level of a dwelling or structure
is less likely to awaken or alert people. Even persons who are awake may not
notice the warning if the alarm is muffled by noise from a stereo, radio, air
conditioner or other appliance, or by passing traffic. Audible warning devices may
not alert the hearing-impaired (strobes or other devices should be provided to
warn these people). Any warning device may fail to alert people with a disability,
deep sleepers, people who have recently used alcohol or drugs, or people on
medication or sleeping pills.
Please note that:
i)Strobes can, under certain circumstances, cause seizures in people with con-
ditions such as epilepsy.
ii) Studies have shown that certain people, even when they hear a fire alarm sig-
nal, do not respond or comprehend the meaning of the signal. 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 on the proper reaction to alarm
signals.
iii) In rare instances, the sounding of a warning device can cause temporary or
permanent hearing loss.
•Telephone lines needed to transmit alarm signals from a premises to a central
station may be out of service or temporarily out of service. For added protection
against telephone line failure, backup radio transmission systems are
recommended.
•System components, though designed to last many years, can fail at any time. As
a precautionary measure, it is recommended that smoke detectors be checked,
maintained, and replaced per manufacturer’s recommendations.
•System components will not work without electrical power. If system batteries are
not serviced or replaced regularly, they may not provide battery backup when AC
power fails.
•Environments with high air velocity or that are dusty or dirty require more frequent
maintenance.
In general, fire alarm systems and devices will not work without power and will not
function properly unless they are maintained and tested regularly.
While installing a fire alarm system may make the owner eligible for a lower insurance
rate, an alarm system is not a substitute for insurance.
1-4151450
Property owners should
Introduction
continue to act prudently in protecting the premises and the people in their premises
and should properly insure life and property and buy sufficient amounts of liability
insurance to meet their needs.
Requirements and recommendations for proper use of fire alarm systems including smoke detectors and other fire alarm devices:
Early fire detection is best achieved by the installation and maintenance of fire
detection equipment in all rooms and areas of the house or building in accordance
with the requirements and recommendations of the current edition of the National Fire
Protection Association Standard 72, National Fire Alarm Code (NFPA 72), the
manufacturer’s recommendations, State and local codes and the recommendations
contained in Guide for the Proper Use of System Smoke Detectors, which is made
available at no charge to all installing dealers. For specific requirements, check with
the local Authority Having Jurisdiction (ex. Fire Chief) for fire protection systems.
Requirements and Recommendations include:
•Smoke Detectors shall be installed in sleeping rooms in new construction and it is
recommended that they shall also be installed in sleeping rooms in existing
construction.
•It is recommended that more than one smoke detector shall be installed in a
hallway if it is more than 30 feet long.
•It is recommended that there shall never be less then two smoke detectors per
apartment or residence.
•It is recommended that smoke detectors be located in any room where an alarm
control is located, or in any room where alarm control connections to an AC
source or phone lines are made. If detectors are not so located, a fire within the
room could prevent the control from reporting a fire.
•All fire alarm systems require notification devices, including sirens, bells, horns,
and/or strobes. In residential applications, each automatic alarm initiating device
when activated shall cause the operation of an alarm notification device that shall
be clearly audible in all bedrooms over ambient or background noise levels (at
least 15dB above noise) with all intervening doors closed.
•It is recommended that a smoke detector with an integral sounder (smoke alarm)
be located in every bedroom and an additional notification device be located on
each level of a residence.
•T o keep your 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 14 of NFPA 72, 2010 Edition shall be
followed. A maintenance agreement should be arranged through the local
manufacturer’s representative. Maintenance should be performed annually by
authorized personnel only.
The most common cause of an alarm system not functioning when a fire occurs is
inadequate maintenance. As such, the alarm system should be tested weekly to
make sure all sensors and transmitters are working properly.

*Regulated for NAC circuits
*Special application when used for auxiliary power circuits.
3-2151450
Before You Begin Installing
3.4Wiring Specifications
Induced noise (transfer of electrical energy from one wire to another) can interfere
with telephone communication or cause false alarms. To avoid induced noise, follow
these guidelines:
•Isolate input wiring from high current output and power wiring. Do not pull one
multi-conductor cable for the entire panel. Instead, separate the wiring as follows:
High voltageAC power Terminals
SLC loopsPhone line circuits
Notification circuitsNAC1 through NAC2
Relay circuitsSBUS Wiring
•Do not pull wires from different groups through the same conduit. If you must run
them together, do so for as short a distance as possible or use shielded cable.
Connect the shield to earth ground at the panel. You must route high and low
voltages separately.
•Route the wiring around the inside perimeter of the cabinet. It should not cross the
circuit board where it could induce noise into the sensitive microelectronics or pick
up unwanted RF noise from the high speed circuits. See Figure 3-1 for an
example.
•High frequency noise, such as that produced by the inductive reactance of a
speaker or bell, can also be reduced by running the wire through ferrite shield

3.6Calculating Current Draw and Standby Battery
This section is for helping you determine the current draw and standby battery
requirements (Table 3-2).
3.6.1Worksheet Requirements
The following steps must be taken when determining 5600 current draw and standby
battery requirements.
1. For the 5600, the worst case current draw is listed for the panel and all addressable devices. Fill in the number of addressable devices that will be used in the
system and compute the current draw requirements for alarm and standby.
Record this information in the Current Calculation Worksheet at Line A.
2. Add up the current draw for all auxiliary devices and record in the table at Line B.
3. Add up all notification appliance loads and record in the table at Line C.
4. For notification appliance circuits and auxiliary devices not mentioned in the manual, refer to the device manual for the current ratings.
5. Make sure that the total alarm current you calculated, including current for the
panel itself, does not exceed 2.0 A. This is the maximum alarm current for the
5600 control panel.
If the current is above 2.0 A you will need to use a notification power expander(s)
such as the Silent Knight 5495 power module to distribute the power loads so that
the 5600 or the power expanders do not exceed their power rating.
6. Complete the remaining instructions in the Current Calculation Worksheet for
determining battery size requirements.
