alarms protect package

E/One Sewer Systems has added Protect Plus for duplex grinder pump stations to its Sentry alarm panel offerings, further enhancing the strongest panel line in the category.

E/One Sentry alarm panels are UL-listed and include lockable, NEMA 4X-rated enclosures. From basic monitoring to advanced warning of pending service needs, E/One Sentry panels are customizable and designed for use with simplex and duplex Extreme Series grinder pump stations.

The Protect Plus panel’s dead front includes a membrane switch with LED indictors and an LCD message display. The Protect Plus option provides protection from low voltage (brownout), run dry and high system pressure situations. With each condition, a lockout cycle will prevent the motor from operating, the Trouble LED will illuminate and the LCD will display the lockout message.

Features exclusive to Protect Plus include: high/low voltage monitoring; high/low wattage monitoring; extended run time; cycle/event counter; adjustable run time limit; adjustable power-up and alarm delays; and system self-test.

Available options include generator receptacle with auto transfer; main service disconnect; E/One’s Remote Sentry (indoor alarm module); and an external auto-dialer.
