Software Operation
1. Functions - The touchscreen consists of a combination of icon icons and function icons. The icons
are; the door icon, the intercom icon, the camera icon, the page icon, utilities icon and group icons.
The function icons include unlock, stop, Hold open, isolate, utilities, interlock override, emergency
evacuation, disable panel, silence, and reset. Pressing any of these icons will result in the DVS
announcing the action performed.
2. Door Control - Pressing the Door Icon without a menu active will result in the act of locking the
door. Unlock, Hold Open, Stop, Local Access, and isolate are menu functions that act with two
keystrokes to make the door operate. Two keystroke operations for unlocking a door are critical so
that doors cannot accidentally be unlocked. The keystrokes required to open an overhead door are
the same. The officer will first press the Unlock icon in the Door Control menu area which will
cause the DVS to announce "unlock"; then within 3 seconds, press the door icon on the graphic at the
location of the door and the DVS will announce the actual name of the door as defined by Harris
County. The door will become unlocked. Other doors may be unlocked by pressing other door icons
within 3 seconds of the first. After 3 seconds of no icon depressions, or when another menu function
is selected, or the Reset icon is pressed, the Unlock (or other command) cancels. After the door has
unlocked for a specified amount of time, it will then relock automatically. To stop the motion of an
overhead, door, the officer will press the STOP icon and the door icon.
Using the Hold Open feature will unlock the door and keep it electrically unlocked until the officer
presses the door icon only. The respective menu icon is illuminated during the 3-second selection
process.
a. Door Control Indicators: The door icon and a Door Status Icon are located on the graphic at each
controlled door. The Door Status Icon is a graphical representation of the door. A swinging door
depicts the door swing displays as secure, in mid travel, or fully open.
The door icon is gray and the Door Status Icon is gray outlined and is shown closed when the
door is locked and secured.
The door icon is red and the Door Status Icon is gray outlined and is shown closed when the
door is powered but the lock status switch, the bolt position switch, and the door position
switch are still indicating that the door is secure.
The door icon is red and the Door Status Icon is red and is shown open when then door is
powered and open.
The door icon is gray and the Door Status Icon is red and is shown open when then door is not
powered but is open.
The Door Status Icon flashes red and shows the current status of the door if the door is
violated or opened manually.
b. Interlocked Doors are bordered around their icons in yellow when a door in a designated interlock
group is unsecured. If an interlocked door is attempted to be unlocked, an Information Dialog
box will appear indicating the door cannot be opened because of the interlock condition.
c. The Reporter/Logger records to disk all openings, unlocking, re-locking, secure actions, door
position, lock status, violations, violation silencing, violation resetting, interlock violations, and
resetting of interlock violations.
