System Sensor warrants its enclosed product 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 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 obliga-
tion 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 Sensor’s toll free number 800-SENSOR2 (736-7672) for a Return Authorization
number, send defective units postage prepaid to: System Sensor, Returns Department, RA

#__________, 3825 Ohio Avenue, St. Charles, IL 60174. Please include a note describing
the malfunction and suspected cause of failure. 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.

WARNING

THE LIMITATIONS OF WATERFLOW ALARM DEVICES

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 wa-

terflow 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.
