Electrical Symbols — Switches and Relays

In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. The mechanism of a switch may be operated directly by a human operator to control a circuit (for example, a light switch or a keyboard button), may be operated by a moving object such as a door-operated switch, or may be operated by some sensing element for pressure, temperature or flow. A relay is a switch that is operated by electricity. Switches are made to handle a wide range of voltages and currents; very large switches may be used to isolate high-voltage circuits in electrical substations. 26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.
The vector stencils library Alarm and access control contains 80 symbols of digital proximity equipment, locking hardware, and access control equipment.
"An alarm device or system of alarm devices gives an audible, visual or other form of alarm signal about a problem or condition. Alarm devices are often outfitted with a siren." [Alarm device. Wikipedia]
"An access control point, which can be a door, turnstile, parking gate, elevator, or other physical barrier, where granting access can be electronically controlled. Typically, the access point is a door. An electronic access control door can contain several elements. At its most basic, there is a stand-alone electric lock. The lock is unlocked by an operator with a switch. To automate this, operator intervention is replaced by a reader. The reader could be a keypad where a code is entered, it could be a card reader, or it could be a biometric reader. Readers do not usually make an access decision, but send a card number to an access control panel that verifies the number against an access list. To monitor the door position a magnetic door switch can be used. In concept, the door switch is not unlike those on refrigerators or car doors. Generally only entry is controlled, and exit is uncontrolled. In cases where exit is also controlled, a second reader is used on the opposite side of the door. In cases where exit is not controlled, free exit, a device called a request-to-exit (REX) is used. Request-to-exit devices can be a push-button or a motion detector. When the button is pushed, or the motion detector detects motion at the door, the door alarm is temporarily ignored while the door is opened. Exiting a door without having to electrically unlock the door is called mechanical free egress. This is an important safety feature. In cases where the lock must be electrically unlocked on exit, the request-to-exit device also unlocks the door." [Access control. Wikipedia]
Use the design elements library Alarm and access control for drawing layout floor plans, blueprints, and wiring diagrams of intrusion systems, time and attendance systems, card and code access control security systems, internal and external security control systems using the ConceptDraw PRO diagramming and vector drawing software.
The shapes library Alarm and access control is included in the Security and Access Plans solution from the Building Plans area of ConceptDraw Solution Park.

How To use House Electrical Plan Software

How we can conduct the electricity at house correctly without a plan? It is impossible. The House electrical diagram depicts locations of switches, outlets, dimmers and lights, and lets understand how you will connect them. But design of House Electrical Plan looks a complex task at a glance, which requires a lot of tools and special experience. But now all is simple with all-inclusive floor plan software - ConceptDraw DIAGRAM. As a house electrical plan software, the ConceptDraw DIAGRAM contains libraries with a large range of professional lighting and electrical symbols, ready-to-use electrical plans samples and examples, and built-in templates for creating great-looking Home floor electrical plans. It is a fastest way to draw Electrical circuit diagrams, Electrical wiring and Circuit schematics, Digital circuits, Electrical equipment, House electrical plans, Satellite television, Cable television, Home cinema, Closed-circuit television when are used the tools of Electric and Telecom Plans Solution from ConceptDraw Solution Park. Files created in Visio for Mac app can be easily imported to ConceptDraw DIAGRAM. Also you may import stencils and even libraries. Try for free an alternative to Visio that Apple users recommend.

Electrical Symbols — Thermo

A thermocouple is an electrical device consisting of two different conductors forming electrical junctions at differing temperatures. A thermocouple produces a temperature-dependent voltage as a result of the thermoelectric effect, and this voltage can be interpreted to measure temperature. Thermocouples are a widely used type of temperature sensor. 26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.
"A security alarm is a system designed to detect intrusion – unauthorized entry – into a building or area. Security alarms are used in residential, commercial, industrial, and military properties for protection against burglary (theft) or property damage, as well as personal protection against intruders. Car alarms likewise protect vehicles and their contents. Prisons also use security systems for control of inmates.

Some alarm systems serve a single purpose of burglary protection; combination systems provide both fire and intrusion protection. Intrusion alarm systems may also be combined with closed-circuit television surveillance systems to automatically record the activities of intruders, and may interface to access control systems for electrically locked doors. Systems range from small, self-contained noisemakers, to complicated, multi-area systems with computer monitoring and control." [Security alarm. Wikipedia]
