Do not drill into the base as this creates
metal shavings which can create
electrical hazards and damage the
device. Drilling voids the warranty.

Testing
The frequency of inspection and testing for the Model VSR and its associated protective monitoring system shall 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 shall 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 is not recommended or advisable.
A minimum flow of 10 GPM (38 LPM) is required to activate this device.
Advise the person responsible for testing of the fire protection system that this system must be tested in accordance
with the testing instructions.

An uninsulated section of a single conductor should not be looped
around the terminal and serve as two separate connections. The
wire must be severed, thereby providing supervision of the
connection in the event that the wire become dislodged from under
the terminal. Failure to sever the wire may render the device
inoperable risking severe property damage and loss of life.
Do not strip wire beyond 3/8" of length or expose an uninsulated
conductor beyond the edge of the terminal block. When using
stranded wire, capture all strands under the clamping plate.
Notes:
1. The Model VSR has two switches, one can be used to operate a central
station, proprietary or remote signaling unit, while the other contact
is used to operate a local audible or visual annunciator.
2. For supervised circuits, see “Switch Terminal Connections”
drawing and warning note (Fig. 4).
