CAUTION:
An uninsulated section of a
single conductor should not
be looped around the termi-
nal and serve as two sepa-
rate connections. The wire
must be severed, thereby
providing supervision of the
connection in the event that
the wire becomes dislodged
from under the terminal.
TESTING
The frequency of inspection and testing for the model VSR-F 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).
If provided, the inspector’s test valve, that is 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 flow detection device on the system, application of the
VSR-F is not recommended or advisable.
A minimum flow of 10 gpm (38 Lpm) is required to activate this device.
IMPORTANT NOTICE: Please advise the person responsible for testing of the fire protection system that this system must be
tested in accordance with the testing instructions.
