Electronic Systems

• Many building systems can now be controlled
  electronically with computers

4
Electronic Systems

• Such electronic systems include a centralized
  computer and control units (touch-screen or
  keyboard) near entry doors and in the master
  bedroom

5
Electronic Systems

• Lights, alarms, safety devices, telephones, and
  heating and air conditioning units
• are some examples of building systems that can be
  controlled electronically

6
High-technology features

• High-technology features that should be
  considered in the architectural design process
  are those that

7
High-technology features

• Monitor smoke, gas, sound, and movement and sound
  an alarm when established levels are exceeded.
• Monitor and adjust heating, cooling, and humidity
  levels for each room
• Provide videophone intercom communication between
  entrances and selected rooms, including
  synthesized voice response to visitors

8
High-technology features

• Open and close, lock and unlock doors, windows,
  vents, gates, and vents from a central control
  center
• Turn on or off appliances, audio systems, or VCRs
  from a central control center directly or on
  timed sequences
• Monitor and/or time the opening and closing of
  solar energy devices, including window shades and
  drapes

9
High-technology features

• Control lighting circuits from a central location
  directly or on timed sequences
• Program combinations of controls to activate
  systems on a timed basis for night, morning,
  midday, evening, work week, weekend, or vacation
  modes of operation
• Are capable of activation via outside, inside,
  and remote phone commands. Some systems use
  electronically synthesized voice commands for
  communication

10
High-technology features

• Monitor intruder action by body heat (infrared
  sensors), motion, light interruption, or noise
  levels to automatically alarm occupants and/or
  security command center
• Record images for immediate use and future
  reference with closed-circuit video cameras
  interfaced with a computer

11
High-technology features

• Automation systems can be combined, for instance,
  to automatically dial police and fire departments
  when sensors are activated
• Security companies usually design total security
  systems as specified by the designer

12
Electronic System Drawings
13
Electronic System Drawings

• After outlets and switches are located on floor
  plans, electronic systems are added with special
  symbols
• The control units and the devices for any
  combination of these systems may be drawn
  directly on the electrical plans
• Separate system plans may also be prepared

14
Security Systems

• Designing security systems involves
• specifying the locations of controls and of sonic
  (sound) motion,
• and heat sensor devices
• These locations are drawn on floor plans with
  special symbols

Surge and Lightening Protection

• A power surge can damage or destroy televisions,
  VCRs, steroes, and computers
• Surge protection devices should be provided at
  the distribution panel for the entire system

17
Surge and Lightening Protection

• Lightning rods (air terminals) can reduce
  lightning damage by providing a grounding path of
  least resistance to discharge the electricity

18
Surge and Lightening Protection

• Rods are placed on rooftops and are connected to
  cables at diagonal corners of a building
• The cables extend into the ground, two feed from
  the foundation

19
Communication Systems

• Positions and connections of doorbells, chimes,
  music, and any communication units need to be
  included on the floor plan
• Connections of audio devices with remote
  speakers, or television cables with TV sets and
  VCRs, are similarly indicated

20
Integrated Systems

• Security, communications, and device-control
  units may be combined into one integrated system
• Automated systems can activate particular parts
  of the integrated system, such as climate control
  or lighting, on a timed basis

21
Integrated Systems

• Similarly, remote controls can be used to control
  any part or all of the system
• These remote controls are low-voltage (24 volt)
  switching systems
• The electrical plan should show the position of
  the master control panel and the remote

22
The Complete Plan
23
The Complete Plan

• Drawing a complete electrical plan involves all
  of the input included in the room plans
• In addition, lines must be drawn
• between switches and fixtures which are in
  different rooms,
• on different levels,
• or between the interior and exterior

24
The Complete Plan

• When a link is made from one drawing to another,
• the line is labeled with the contact point on the
  other drawing
• This is common bet5ween first-and second-level
  drawings
• It is also common between interior and exterior
  links
