Potter VSR-S Mode D'emploi page 4

Typical Electrical Connections
Fig 6
The VSR-S does not require power to operate. Do not connect AC power directly to the terminals as this will damage the switch.
The terminals are for switching power to an indicating appliance such as a bell or strobe. Similar to how a light switch is used to switch power to a
light. The terminals can also be used to connect to a fire/security panel.
Notes:
1. The Model VSR-S 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 Clamping Plate Terminal" drawing and warning note (Fig. 5).

CAUTION
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).
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-S is not
recommended or advisable.
A minimum flow of 10 GPM (38 LPM) is required to activate this device.
Please advise the person responsible for testing of the fire
protection system that this system must be tested in accordance
with the testing instructions. Do not obstruct or otherwise prevent
the trip stem of the flow switch from moving when water flows as
this could damage the flow switch and prevent an alarm. If an alarm
is not desired, a Flowswitch Bypass Switch should be used (refer to
Potter data sheet 5401554), or a qualified technician should disable
the alarm system.
