Potter Electric Signal (OSYSU-2) Supervisory Switch
The Potter OSYSU-2 is a high-reliability supervisory switch designed to monitor the open position of Outside Screw and Yoke (OS&Y) type gate valves. As a critical component in fire sprinkler systems, it helps prevent unauthorized or accidental closing of water supply valves, ensuring that the system remains operational. The “2” in OSYSU-2 indicates it comes equipped with two sets of Single-Pole, Double-Throw (SPDT) switches for redundant monitoring. This is a direct replacement for the OSYSU-A2 supervisory switch.
Key Features
- Dual Switch Capability: Contains two sets of SPDT (Form C) contacts, allowing for monitoring of two independent circuits.
- Broad Compatibility: Fits most 2″ to 12″ (50mm–300mm) OS&Y valves, with the capability to fit some valves as small as ½”.
- Rugged Construction: Features a NEMA 4X and 6P rated enclosure, making it suitable for both indoor and outdoor use, including direct sunlight or potential water submersion.
- Tamper Resistance: Equipped with a tamper-resistant cover, requiring a special tool (included) for removal to prevent unauthorized tampering.
- Easy Installation: Features a knurled mounting bracket to prevent slippage and a fine-adjustment mechanism for quick setup.
- Visual Indicators: Includes visual indicators that assist with installation and show the status of the switch.
