WARNING
!
These fire protection devices require correct wiring
to function. It is the responsibility of the purchaser
to provide correct wiring installation. SARGENT
accepts no responsibility for incorrect wiring.
Devices wired incorrectly may be damaged and
this is not covered under warranty.
Life safety devices including door release devices
require correct positioning and appropriate
selection for the required task. It is the responsibility
of the purchaser to select appropriate hardware
and provide professional installation. It is the
responsibility of the purchaser to insure that NFPA
and other applicable fire codes are met. Door
release devices function properly only if the door
is free to close. SARGENT accepts no responsibility
for incorrect installation of its equipment.
Smoke detectors will not work without power. AC
or DC powered smoke detectors will not work if
the power supply is cut off for any reason.
All high voltage wiring should be undertaken by a
qualified professional licensed electrician. It is the
responsibility of the purchaser to insure that
installation meets all applicable local and national
electrical codes.
Smoke detectors will not sense fires which start
where smoke does not reach the detectors.
Smoke from fires in chimneys, in walls, on roofs or
on the other side of closed doors may not reach
the smoke detector and alarm it.
A detector may not detect a fire developing on
another level of a building. For this reason, detectors
should be located on every level of a building.
Smoke detectors have sensing limitations.
Photoelectric detectors sense smoldering fires
better than flaming fires. Ionization detectors offer
a broad range of fire-sensing capability, but they
are better at detecting fast, flaming fires than slow
smoldering fires. Because fires develop in different
ways, and are often unpredictable in their growth,
neither type of detector is always best, and a given
detector may not always provide warning of a fire.
In general, detectors cannot be expected to provide
warnings for fires resulting from inadequate fire
protection practices, violent explosions, escaping
gas, improper storage of flammable liquids like
cleaning solvents, other safety hazards, or arson.
Smoke detectors used in high air velocity conditions
may fail to alarm due to dilution of smoke densities
created by such frequent and rapid air exchanges.
Additionally, high air velocity environments may
create increased dust contamination, demanding
more frequent maintenance.
Smoke detectors do not last forever. Even though
detectors are made to last over 10 years, these
components could fail at any time. Therefore, test
your smoke detector system per NFPA 72E at
least semiannually. Clean and take care of your
smoke detectors regularly. Taking care of the fire
detection system you have installed will measurably
reduce your liability risks.
