Product Description


At the first sign of trouble outside, with just one button and virtually no special training or knowledge required, faculty and/or students of all ages can simply press Trilogy's inside 'privacy' button to lock out unauthorized access, instantly locking-down a classroom or area, all while remaining safely within the room. There is no need to open the door, nor use a special key, since the fingertip-activated button is located on the inside door, i.e., the same side as classroom occupants. Trilogy's lockdown function automatically disables free passage through the door and even locks out general PIN user codes, since routine Trilogy keypad access is temporarily suspended whenever the privacy button is activated (even when the lock is time-scheduled for free-access mode).

Instantly, a lock-down override code, however, will reactivate the pushbutton keypad and enable authorized teachers/staff, outside the classroom, to readily bypass the lockout function at any time, should students, etc. accidentally or purposefully activate lockdown mode. (In fact, all master and management codes (11) will permit instant access to the Trilogy protected area.)

Operation PRIVACY: After entering with a PIN pass code the user simply pushes the privacy button on the back of the lock (inner door). Doing so assures privacy, as the lock will not open from the front entry side, until the user exits (the door is reopened from the inside), or optionally, the privacy session “times-out” following a preset duration
RESIDENCY: For residency applications, where accidental resident lock-outs are a concern, or where frequent trips in and out make unlocking the door with code impractical, the residency feature can also be turned on at the lock’s keypad. This programmable “Residency” feature allows users to exit their premises, closing the door behind them and the lock will remain unlocked until it is physically, consciously relocked, with PIN. This free-exit/passage mode enabled by the residency feature is a welcome convenience for those needing to make several trips in and out of a unit, room or building, and is likewise ideal for residents who, may repeatedly find themselves unintentionally locked out, for example, upon momentarily stepping out the front door, to pick up their mail or newspaper only to have the door accidentally lock behind them.
