  
 Introducing the most versatile Essex Keypad ever built. The K1 Series is the next generation multi format Keypad designed to provide a migration path from a 500 user stand alone access control system to a Keypad reader which provides one of several industry standard outputs.
The unique design of the K1 Series allows the output to be easily configured in the field as any one of the following:
•26 Bit Wiegand Reader
•8 Bit Word Reader
•BCD Reader
•ABA Track II Reader
•Serial ASCII Reader
•500 Code Self Contained Access Controller
Professional Grade
Weather installed in extreme climate conditions or inside a building, this Essex 12 digit 3x4 is unsurpassed in its' ability to tolerate virtually any environment. Utilizing Essex state of the art, Billion Cycle Switch Technology™, the K1 Series 12 Pad 3x4 outperforms other keypads (membrane, conductive rubber, mechanical and other piezoelectric keypads) in indoor, outdoor, harsh and high use applications.
Not all Keypads are the same. Traditional mechanical, membrane or conductive rubber Keypads fail after 5 to 10 million cycles at best. Keypads built with Essex piezoelectric technology have been tested more than 1 Billion cycles without failure. In addition, Essex Keypads are unaffected by extreme environments (rain, snow, ice or heat)
Security Professionals Choice
Over the past decade, the Essex Keypads have become the choice of security professionals worldwide. From banks to airports to government facilities, Essex has been specified for a variety of access control (and equipment control) applications. Installation sites include the Pentagon, the White House, the Chunnel, the Hong Kong International Airport and on commercial aircraft fleets around the world.
