The Potter Amseco VSR-2 is a vane-type waterflow switch for use on wet sprinkler systems. It is UL Listed and FM Approved for use on steel pipe; schedules 10 through 40, size 2".
The VSR-2 may also be used as a sectional waterflow detector on large systems and contains two single pole, double throw, snap action switches and an adjustable, instantly recycling pneumatic retard.

Enclosure
A general-purpose, die-cast enclosure houses the VSR switches and the retard device. Two tamper-resistant screws that need a unique key to remove hold the cover in place. As an extra, there is a field-installable cover tamper switch that can be used to signal illegal cover removal. For this switch's installation instructions, refer to bulletin number 5401103. |
