Testing
The frequency of inspection and testing for the Model VSR-S and its associated protective monitoring system should be in accordance with applicable
NFPA Codes and Standards and/or the authority having jurisdiction (manufacturer recommends quarterly or more frequently.)
An inspector's test valve (usually located at the end of the most remote branch line) should always be used for test purposes. If there are no provisions
for testing the operation of the fl ow detection device on the system, application of the VSR-S is not recommended or advisable.
A minimum fl ow of 10 gpm (38 Lpm) is required to activate this device.
Please advise the person responsible for testing of the fi re protection system that this system must be tested in accordance
with the testing instructions.
Maintenance
Inspect detectors monthly for leaks. If leaks are found, replace the detector. The VSR waterfl ow switch should provide years of trouble-free service.
The retard and switch assembly are easily fi eld replaceable. In the unlikely event that either component does not perform properly, please order
replacement retard switch assembly stock #1029030. There is no maintenance required, only periodic testing and inspection.
Removal
• To prevent accidental water damage, all control valves should be shut tight and the system completely drained before waterfl ow detectors are
removed or replaced.
• Turn off electrical power to the detector, then disconnect wiring.
• Use a wrench on the fl ats of the bushing . Turn the switch counterclockwise to disengage the pipe threads.
• Gently lift with your fi ngers, roll the vane so it will fi t through the hole while continuing to lift the waterfl ow detector.
• Lift detector clear of pipe.
Waterfl ow switches that are monitoring wet pipe sprinkler systems
shall not be used as the sole initiating device to discharge AFFF,
deluge, or chemical suppression systems. Waterfl ow switches used
for this application may result in unintended discharges caused by
surges, trapped air, or short retard times.
