User Interface
Interaction with the lock is accomplished via the pushbutton keypad, the green
and red status lights, the audible buzzer, the outside lock lever, and the
mechanical override key. Through these components, those who are Master and
Manager authorized program the lock and those with access codes unlock it.
There is free egress at all times from inside by turning the inside lock lever.
4.2.1
Pushbutton Keypad
The keypad, located on the outside housing of the lock, is a standard telephone-
style metal-pushbutton keypad displaying ten numeric keys from zero to nine
and the alphanumeric keys <*> and <#>.
By entering a valid access code combination and turning the outside lock lever,
the user unlocks the door. The keypad is also used to program the lock, including
adding, deleting, or changing authorization and access codes or enabling a
special lock mode such as passage mode. The <#> key is used to start and end a
programming session and is also used following each command code entered.
If an undesired command code is entered, the <*> key can be used to clear the
command before the <#> key is pressed. However, once the <#> key is pressed, the
command is executed.
While entering an access code or during a programming session, five seconds is
allowed between pushbutton entries; however, once the five seconds is up, a
timeout occurs and the access code or the programming session is aborted.

Green And Red Status Lights
The green and red status lights, Light Emitting Diodes (LEDs), are located
immediately above the keypad behind a dark window. The lights are visual
indicators for the lock operations as described below.

Audible Buzzer
The buzzer is an audible status indicator located inside the dark window on the
front lock housing. The buzzer can be programmed to sound at loud or soft levels
or it can be disabled; however, regardless of the setting, it is always enabled at the
loud volume level during a programming session when command codes are
entered. The buzzer emits two tones: one high-pitched and the other low-pitched.
These tones are used as audible indicators for the lock operations as described
