MS-9600LS Series Manual — P/N 52646:B2  2/12/2010

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 develop-
ing 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 detec-
tors be located throughout a protected premise following the 
recommendations 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.systemsen-
sor.com/html/applicat.html.  A study by the Federal Emer-
gency 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 sys-
tem 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 ion-
izing-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 predeter-
mined 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 pro-
tection 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 sys-
tem for the connection of alarm transmission wiring, communi-
cations, signaling, and/or power.  If detectors are not so 
located, a developing fire may damage the alarm system, crip-
pling 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 medica-
tion.  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 responsi-
bility 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 com-
patible with the control panel.  It is essential to use only equip-
ment 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 tele-
phone line failure, backup radio transmission systems are rec-
ommended.  

The most common cause of fire alarm malfunction is inade-
quate 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 stan-
dards.  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 main-
tenance agreement should be arranged through the local man-
ufacturer'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.
