from date of manufacture. System Sensor makes no other express warranty for
this air duct smoke detector. No agent, representative, dealer, or employee of
the Company has the authority to increase or alter the obligations or limitations
of this Warranty. The Company’s obligation of this Warranty shall be limited
to the replacement of any part of the product which is found to be defective
in materials or workmanship under normal use and service during the three
year period commencing with the date of manufacture. After phoning System

The Company shall not be obligated to 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 negligence or fault. Some states do not allow the
exclusion or limitation of incidental or consequential damages, so the above
limitation or exclusion may not apply to you. This Warranty gives you specific
legal rights, and you may also have other rights which vary from state to state.
1. Waterflow detectors may not work or operate properly if sprinkler piping being
monitored is plugged with pipe scale, mud, stones or other foreign material. Sprinkler
systems should be checked regularly for such blocking material.
2. Alarms generated by the activation of waterflow detectors may not be received by
a central station if telephone or other communication lines to the detector are out of
service, disabled, or open.
3. Vane-type waterflow detectors have a normal service life of 10–15 years. Hard water
systems, however, may reduce waterflow detector service life significantly.

4. Waterflow detectors are not a substitute for insurance. Building owners should always
insure property and lives being protected by sprinkler systems.
5. If valves controlling the water supply to a sprinkler system are closed, vane-type
waterflow detectors will not work. All valves controlling a sprinkler water supply
should be sealed or locked in the normally open position. The normally open position
should be monitored by a sprinkler supervisory switch.
