The electric hinge provides an easy means to monitor the opening as well as transferring power from the frame into the door.
Electric hinge modifications can be either exposed on the surface of the hinge or concealed in the hinge. When concealed, the modifications are not visible and normally go undetected by personnel using the openings.

All of the Hager Companies electric hinges have been tested through UL in order that our products can be used on fire-rated or labeled openings. 

Another important point to remember, an electrically modified hinge is for low voltage power transfer only (48 volts or under). Higher voltages are not allowed because of the potential dangers. Also, a consideration is the amperage rating of the power transfer hinges. Hager’s 18-gauge wires are rated for 50 volts AC/DC at 10 amps continuous. The maximum inrush is 20 AMPS for 4 seconds per wire. Hager 28-gauge wires include amperage ratings of 3.5 AMPS/continuous duty and 16.0 AMPS/ intermittent duty (pulse).

Both leaves are mortised, one leaf in the door and one leaf in the frame (wood door or hollow metal door with wood or hollow metal frame).
