This revolutionary hinge is the first of its kind to offer several advantages to the installer/customer. Two of the wires are heavy 18 gauge, silver coated, high conductivity Teflon jacketed conductors and four of the wires are 28 gauge, silver coated high conductivity conductors. The two 18 awg wires can be used with electric latch retraction devices, such as the Von Duprin EL 33 and 99 series panic devices. In fact, this EL hinge was engineered for just such uses. The smaller 28 awg wires can be used for controls and switches.
Not only is this PTH (Power Transfer Hinge) stronger and able to withstand more inrush than any other electric hinge on the market, but it is also independently tested to over 800,000 cycles on average before a wire breaks or goes to ground. That is 8 times the UL requirement of 100,000 cycles typical for most products on the market.
This hinge is also burn tested and UL10C listed for use on fire rated doors and frames. Marray was the first with such a listing.

After a standard hinge is modified, it no longer meets ANSI 156.1, or NFPA 80 and must be re-tested to ensure it will not default in a fire situation. Be sure when you order hinges for your listed doors that you install hardware that is fire listed. This will benefit you by ensuring that you do not de-listed and de-certified a fire listed door by not providing the proper listed hardware.
Most jurisdictions will begin annual fire door inspections under the 2007 edition of NFPA 80. If your hinge is not listed for fire, you may have to replace the door. Marray maintains a very large inventory of these hinges for same day shipment.

- and on the last page will you choose what knuckle and corner style you would like.
Certain combinations of options are not common and may not be in inventory. If this is the case a special order will need to be placed which can take up to 7 weeks to be processed.
