FOR MONTGOMERY COUNTY DETENTION CENTER
SECURITY CAMERA SYSTEM 17000-32
d. Based on the preliminary meeting, the Division 17 Contractor
shall develop the control and display software. The control screens
shall be submitted as shop drawings on both paper prints and
electronic CAD files.
e. Any changes or modifications to the system resulting from the
shop drawings shall be incorporated into the system and
demonstrated at a meeting to finalize the system.
f. Any modifications to the system resulting from the meeting will
be incorporated and demonstrated at the factory testing.
F. General Description:
1. The Security Monitoring and Control System is an integrated monitoring
and control system which includes a networked Wonderware HMI system
and Allen-Bradley programmable logic controllers.
2. The Security Monitoring and Control System interfaces directly with the
following systems:
a. Door Control System
b. Closed Circuit Television System

G. Wonderware HMI System Description:
1. Screen icon inputs and outputs provide the human interface device for
security alarm monitoring and control of security devices including doors,
cameras, and intercoms.
2. The Dell PC consists of a 21" high resolution color LCD touch screen
monitor and high performance processor. The LCD will sit on a
freestanding pedestal similar to the existing ones. Coordinate casework
opening dimensions and configurations with engineer.
3. Control Functions: Wonderware on the personal computer stores the
graphic images consisting of icons which performs the function of a
typical push button switch. When a particular icon is activated by a
pointing device, the personal computer sends the information to the Allen-
Bradley Programmable Logic Controller (PLC). The PLC then performs
logic functions (such as timing and interlocking) and activates the
appropriate field device(s) such as door locks or video switcher control
based on the command.
4. Monitoring Functions: The PLC receives signals from the field devices,
performs the necessary logic functions and routes the required information
to the HMI personal computer for display on the LCD terminal.
