The newly enhanced PS Patrol® high-water alarm system for pumping station applications employs a receptacle to accept a 120-V pump and piggy-back pump switch. The angled design of the clear enclosure includes a removable cover for easy access for field wiring. All internal components are sealed within the cover for protection from the elements. The red LEDs illuminate the top of the cover in an alarm condition for easy 360-degree visual identification. The design of the controller accepts a 5-inch square plastic post or 4-inch pipe/conduit for mounting. The PS Patrol features automatic alarm reset, green power-on indicator, and a flush-mount horn-silence/alarm-test switch. The electrical potting cavity provides a method to seal power cables, and a cord seal is included for sealing switch and pump cables. Auxiliary contacts are included for attachment of remote devices.
