Electric Door Strikes
An electric door strike allows doors to remain locked to public access (usually on the exterior side of the door). However, the door may still be opened quickly and easily from the inside without the use of a key. These commercial and industrial rated door strikes can withstand the traffic involved with access control applications. They are tested to 500,000 cycles. These strikes are fail-secure for free exit applications. They can be used with cylindrical, narrow line and mortise locks with centerline latch entry. The strikes are listed under UL1034, ANSI/BHMA E09321 and New York City MEA 404-91-M.
