The Alarm Lock Trilogy T3 weatherproof electronic digital proximity and keypad cylindrical lock leverset has an HID compatible proximity card or key fob reader (each sold separately), supports up to 2,000 user entry codes for secure keyless entry, is for installation on exterior and interior doors, has a satin chrome finish and a reversible lever handle for right- or left-hand operation. The leverset can be manually programmed through the keypad or a computer to recognize up to 2000 user entry codes of 3 to 6 digits, and can store up to 500 lock/unlock events grouped into schedules to permit or deny access at specified times and days. It maintains a time-stamped audit trail record of the last 40,000 occurrences of successful and unsuccessful entry, which can be retrieved to a computer or printed to an infrared printer (sold separately). An automatic lockout disables the keypad up to 60 seconds after multiple failed code inputs, to discourage unauthorized access. LED indicators and sound provide feedback for code entry and manual programming. Programming through a Windows-compatible computer requires the Trilogy PC Software Kit (sold separately). The leverset has a cylindrical lock mechanism and a solid brass fixed key cylinder provides a key override to engage or release the lock. The leverset is rated for temperatures from -31 to +151 degrees F (-35 to +66 degrees C) for use on exterior, as well as interior doors. The leverset trim is made of stainless steel with a satin chrome finish to resist corrosion. The leverset is powered by 5 AA batteries (included). It meets American National Standards Institute (ANSI)/ Builders Hardware Manufacturers Association (BHMA) grade 1 standards for commercial buildings, and standards that can help comply with the Americans with Disabilities Act (ADA) when properly installed. It is also Underwriters Laboratories (UL) listed for a 3-hour fire rating and Federal Communications Commission (FCC) certified.SpecificationsLock typeMortiseUnique user codes supported2000Number of digits each code3 to 6Lock/unlock events500Audit trail40,000Key overrideSolid brass, 6-pin cylinder with pinned 5 SC1 keywayTemperature rating-31 to +151 degrees F (-35 to +66 degrees C)Proximity reader frequency13.56 MHzOperation5 AA batteries, 60,000 cyclesFits door thickness1-5/8 to 1-7/8"Backset width2-3/4" Access control keypads for doors limit entry to authorized users. The door remains locked until a recognized code is entered through the numeric keypad and returns to the locked state when the door is closed after passage. Many units include a leverset with a lock mechanism for key override to bypass the keypad. The lock mechanism may be a fixed key cylinder installed by the manufacturer, or it may accept an interchangeable core that can be replaced if security is compromised. A cylindrical lock mechanism requires two bored perpendicular holes in the door for installation, one in the door face and a crossbore hole in the door edge. A mortise lock mechanism fits into a pocket recess in the door edge. Alarm Lock Systems manufactures mechanical and electronic access controls for secure entry and egress. The company, headquartered in Amityville, NY, meets International Organization for Standardization (ISO) standard 9002.What"s in the Box?Trilogy T3 electronic digital keypad leversetMortise latchStrike plateLatch coverTrim plateBattery pack with 5 AA batteries
