Interlogix 1078-N, 1078M-10PKG Specsheet

The GE Interlogix 1078 Series Steel Door contacts are designed

specifically for use in the steel doors commonly found in

commercial building applications. The unique housing design

features a rugged unibody construction with flexible ribbed sides

for quick, secure installation without gluing. The magnet housing

isolates the magnet from the surrounding steel for maximum gap

distances, both make and break. Over seven models including:

Wide Gap, SPDT, DPDT, and Biased for High Security applications

make the 1078 Series the most widely used and comprehensive

line available.

On available models a terminal connection (T) makes installation

easier. Simply strip the wire, insert it into the terminal block and

tighten. The terminal accepts any wire size from 14 to 22 gauge,

and has a unique one piece design for added strength.

An optional Rare Earth Magnet is available. It is designed for use

in metal entry/exit doors with a channel in the top of the door. The

magnet eliminates the need to cut a mounting hole in the door

channel. The flexible magnet housing can be compressed

to accommodate a variety of channel widths for quick, easy

installation. Adhesive is recommended.

The contact contains a hermetically sealed magnetic reed switch.

The reed shall be potted in the contact housing with a

polyurethane based compound. Contact and magnet housing shall

snap-lock into a 3/4" or 1" dia. hole. Housings shall be molded of

flame retardant ABS plastic. Color of housings shall be off-white,

grey or mahogany brown. The magnet shall be made of Alnico V.

Rare Earth Magnet shall be made of neodymium iron boron.

Snap-lock insulation bushing for tight fit and maximum gap

in steel.

Both contact and magnet plastic housings are constructed of

one piece of thick-walled ABS plastic for maximum strength

and durability.
