Three-Year Limited Warranty
System Sensor warrants its enclosed smoke detector base to be free
from defects in materials and workmanship under normal use and
service for a period of three years from date of manufacture. System Sen-
sor makes no other express warranty for this smoke detector
base. No agent, representative, dealer, or employee of the Company has
the authority to increase or alter the obligations or limitations of this War-
ranty. The Company’s obligation of this Warranty shall be limited to the
repair or replacement of any part of the smoke detector base which is
found to be defective in materials or work
manship under normal use and service during the three year period com-
mencing with the date of manufacture. After phoning System Sensor’s toll
free number 800-SENSOR2 (736-7672) for a Return Authorization num-
ber, send defective units postage prepaid to: System Sensor, Repair De-
partment, RA #__________, 6581 Kitimat Rd., Unit #6, Mississauga, ON,
L5N 3T5. Please include a note describing the malfunction and suspected
cause of failure. The Company shall not be obligated to repair or replace
units which are found to be defective because of damage, unreasonable
use, modifications, or alterations occurring after the date of manufacture.
In no case shall the Company be liable for any consequential or incidental
damages for breach of this or any other Warranty, expressed or implied
whatsoever, even if the loss or damage is caused by the Company’s neg-
ligence or fault. Some legislations do not allow the exclusion or limitation
of incidental or consequential damages, so the above limitation or exclu-
sion may not apply to you. This Warranty gives you specific legal rights,
and you may also have other rights which vary under common law.
The smoke detector used with this base is designed to
activate and ini-
tiate
emergency action, but will do so only when it is used in conjunction
with an authorized fire alarm system. This detector must be installed in
accordance with CAN/ULC-S524.
Smoke detectors will not work without power.
AC or DC powered
smoke detectors will not work if the power supply is cut off.
Smoke detectors will not sense fires which start where smoke does
not reach the detectors.
Smoldering fires typically do not generate a lot
of heat which is needed to drive the smoke up to the ceiling where the
smoke detector is usually located. For this reason, there may be large
delays in detecting a smoldering fire with either an ionization type detec
-
tor or a photoelectric type detector. Either one of them may alarm only
after flaming has initiated which will generate the heat needed to drive the
smoke to the ceiling.
Smoke from fires in chimneys, in walls, on roofs or on the other side of a
closed door(s) may not reach the smoke detector and alarm it. A detector
cannot detect a fire developing on another level of a building quickly or at
all. For these reasons, detectors
shall be located on every level and in
every bedroom within a building.
Smoke detectors have sensing limitations, too.
Ionization detectors
and photoelectric detectors are required to pass fire tests of the flaming
and smoldering type. This is to ensure that both can detect a wide range
of types of fires. Ionization detectors offer a broad range of fire sensing
capability but they are somewhat better at detecting fast flaming fires than
slow smoldering fires. Photoelectric detectors sense smoldering fires bet
-
ter than flaming fires which have little, if any, visible smoke. Because fires
develop in different ways and are often unpredictable in their growth, nei-
ther type of detector is always best, and a given detector may not always
provide early warning of a specific type of fire.
In general, detectors cannot be expected to provide warnings for fires
resulting from inadequate fire protection practices, violent explosions,
escaping gases which ignite, improper storage of flammable liquids like
cleaning solvents which ignite, other similar safety hazards, arson, smok-
ing in bed, children playing with matches or lighters, etc. Smoke detectors
used in high air velocity conditions may have a delay in alarm due to
dilution of smoke densities created by frequent and rapid air exchanges.
Additionally, high air velocity environments may create increased dust
contamination, demanding more frequent maintenance.
To keep your equipment in excellent working order, ongoing mainte-
nance is required per the manufacturer’s recommendations and ULC
standards. At a minimum, the requirements of the National Fire Alarm
Code, shall be followed. A preventative maintenance agreement should
be arranged through the local manufacturer’s representative. Though
smoke detectors are designed for long life, they may fail at any time.
Any smoke detector, fire alarm equipment or any component of that
system which fails shall be repaired or replaced as soon as possible.
