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, following the instruc-
tions in Chapter 5 of NFPA Standard 13A.
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.
WARNING
THE LIMITATIONS OF WATERFLOW ALARM DEVICES
3. Vane-type waterflow detectors have a normal service life of 10-15 years. Hard water
systems, however, may substantially reduce waterflow detector service life.
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.

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
