Important
Please Read Carefully And Save
This instruction manual contains important information
about the installation and operation of waterflow detectors.
Purchasers who install waterflow detectors for use by oth-
ers must leave this manual or a copy of it with the user.
Read all instructions carefully before beginning. Follow
only those instructions that apply to the model you are in-
stalling.
CAUTION
Use vane-type waterflow detectors in wet-pipe systems
only. Do NOT use them in dry pipe, deluge, or preaction
systems. The sudden inrush of water in such systems may
break the vane or damage the mechanism.
Do not use in potentially explosive atmospheres. Do not al-
low unused wires to remain exposed.

Principles Of Operation
Vane-type waterflow detectors mount to water-filled pipes
in sprinkler systems. Waterflow in the pipe deflects a vane,
which produces a switched output–usually after a specified
delay. All waterflow detectors have a pneumatically con-
trolled mechanical delay mechanism. Delays do NOT accu-
mulate; they reset if the flow of water stops before the
entire delay has elapsed. All switches actuate when the wa-
ter flow rate is 10 gallons per minute or greater, but will not
actuate if the flow rate is less than 4 gallons per minute.
This System Sensor installation manual covers the follow-
ing waterflow detectors for sprinkler/fire alarm applica-
tions.
