Basic Flowchart Symbols and Meaning

The vector stencils library Initiation and annunciation contains 9 symbols of Fire Alarm Control Panel (FACP) or Fire Alarm Control Unit (FACU) elements, triggering devices, audible alarm systems, timers, security control equipment, and recording devices.
"A Fire Alarm Control Panel (FACP), or Fire Alarm Control Unit (FACU), is the controlling component of a Fire Alarm System. The panel receives information from environmental sensors designed to detect changes associated with fire, monitors their operational integrity and provides for automatic control of equipment, and transmission of information necessary to prepare the facility for fire based on a predetermined sequence. The panel may also supply electrical energy to operate any associated sensor, control, transmitter, or relay. There are four basic types of panels: coded panels, conventional panels, addressable panels, and multiplex systems." [Fire alarm control panel. Wikipedia]
Use the shapes library Initiation and annunciation to draw layout floor plans, communications schematics and wiring diagrams of security systems using the ConceptDraw PRO diagramming and vector drawing software.
The design elements library Initiation and annunciation is included in the Security and Access Plans solution from the Building Plans area of ConceptDraw Solution Park.

"HVAC (stands for Heating, Ventilation and Air Conditioning) is a control system that applies regulation to a heating and/ or air conditioning system. Usually a sensing device is used to compare the actual state (e.g., temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g., start the blower).
More complex HVAC systems can interface to Building Automation System (BAS) to allow the building owners to have more control over the heating or cooling units. The building owner can monitor the system and respond to alarms generated by the system from local or remote locations." [HVAC control system. Wikipedia]
The vector stencils library "HVAC control equipment" contains 48 symbols of heating, ventilation, air conditioning, refrigeration and automated building control equipment.
Use the design elements library HVAC control equipment to draw HVAC plans, schematic diagrams of heating, ventilation, air conditioning, refrigeration and automated building control systems, environmental control design building plans and equipment layouts using the ConceptDraw PRO diagramming and vector drawing software.
The shapes library HVAC control equipment is contained in the HVAC Plans solution from the Building Plans area of ConceptDraw Solution Park.

The vector stencils library "HVAC controls" contains 23 symbols of HVAC controls (sensors, actuators, timers, controllers, I/ O points).
"HVAC (... Heating, Ventilation and Air Conditioning) is a control system that applies regulation to a heating and/ or air conditioning system. ...
Central controllers and most terminal unit controllers are programmable, meaning the direct digital control program code may be customized for the intended use. The program features include time schedules, setpoints, controllers, logic, timers, trend logs, and alarms. The unit controllers typically have analog and digital inputs that allow measurement of the variable (temperature, humidity, or pressure) and analog and digital outputs for control of the transport medium (hot/ cold water and/ or steam). Digital inputs are typically (dry) contacts from a control device, and analog inputs are typically a voltage or current measurement from a variable (temperature, humidity, velocity, or pressure) sensing device. Digital outputs are typically relay contacts used to start and stop equipment, and analog outputs are typically voltage or current signals to control the movement of the medium (air/ water/ steam) control devices such as valves, dampers, and motors."

Use the design elements library "HVAC controls" for drawing the HVAC system diagrams, controls drawings, and automated building control and environmental control system layuout floor plans using the ConceptDraw PRO diagramming and vector drawing software.
The shapes library "HVAC controls" is included in the HVAC Plans solution from the Building Plans area of ConceptDraw Solution Park.

The vector stencils library "Flowchart" contains 26 symbols for drawing the flow charts using the ConceptDraw PRO diagramming and vector drawing software.
"Flowcharts are used in designing and documenting complex processes or programs. Like other types of diagrams, they help visualize what is going on and thereby help the viewer to understand a process, and perhaps also find flaws, bottlenecks, and other less-obvious features within it. There are many different types of flowcharts, and each type has its own repertoire of boxes and notational conventions. The two most common types of boxes in a flowchart are:
(1) a processing step, usually called activity, and denoted as a rectangular box;
(2) a decision, usually denoted as a diamond.
A flowchart is described as "cross-functional" when the page is divided into different swimlanes describing the control of different organizational units. A symbol appearing in a particular "lane" is within the control of that organizational unit. This technique allows the author to locate the responsibility for performing an action or making a decision correctly, showing the responsibility of each organizational unit for different parts of a single process. ...
Common alternate names include: flowchart, process flowchart, functional flowchart, process map, process chart, functional process chart, business process model, process model, process flow diagram, work flow diagram, business flow diagram. The terms "flowchart" and "flow chart" are used interchangeably." [Flowchart. Wikipedia]
