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
is used to operate a local audible or visual annunciator.
2. For supervised circuits see “Switch Terminal Connections” drawing
and caution note (Fig. 3).
Retard Adjustment
The time delay is factory set at 30 ± 10 seconds.
The delay can be adjusted by rotating the retard
adjustment knob from 0 to the max setting (60-90
seconds). The time delay should be set at the
minimum required to prevent false alarms.

To remove knockouts:
Place screwdriver at edge of
knockouts, not in the center.
Screw the device into the tee fitting as shown.
Care must be taken to properly orient the
device for the direction of waterflow. On sweat
tees, no threaded bushings, inserts, or adapters
are permitted, unless they comply with the
dimensions listed in the chart below.
Important - The depth to the inside bottom of
the tee should have the following dimensions:

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.

There are 12 paddles furnished with each unit.
One for each size of threaded, sweat or plastic
TEE as described in Fig. 2. These paddles have
raised lettering that shows the pipe size and type
of TEE that they are to be used with. The proper
paddle must be used. The paddle must be properly
attached (see drawing) and the screw that holds
the paddle must be securely tightened. Do not use more than three
wraps of teflon tape.
