Electronic Door Entry & Access Control Systems
Electronic Door Entry Systems
Porter-mail is a communication and safety device used to control access to residential and commercial buildings.
Components of an Electronic Door Entry System
Power Supply
Adapts the required voltage (12V or 15V DC) for system components. The power supply’s capacity depends on the number of openers and telephones connected.
Entrance Panel
Houses the buttons, speaker, and microphone for communication. Compact and modular designs accommodate various user numbers. Recessed or surface-mounted installation options are available. Keypad models are also offered by some manufacturers.
Opener
Electrically controlled by individual telephones, the opener is installed in the door lock and operates on 12V or 15V DC.
Telephones
Installed in individual units, telephones communicate with the entrance panel and activate the opener. Advanced models may include special function buttons.
Cable
Consists of numerous flexible, color-coded wires (0.5mm section).
Basic Configuration
Electronic door entry systems can be analog or digital.
Digital Systems
Each phone is programmed via microswitches for system recognition. Suitable for large buildings, with power supply and opener connections similar to analog systems.
Video Intercoms
Offer the ability to transmit images.
Components of a Video Intercom System
Similar to electronic door entry systems, with some key differences.
Street Panel
Includes call button, audio unit, and a built-in camera.
Video Intercom
Features a microphone, speaker, and a small video monitor. Brightness and contrast controls are often included.
Cable
Requires two independent wiring systems: one for communication/call and a coaxial cable for video signal distribution.
Other Configurations
Multiple Entry Points
Buildings with multiple entrances require street panels, feeders, and openers at each access point.
Concierge Systems
One or more entrance panels communicate with a central console managed by a concierge, who then communicates with residents.
Integrated ITC Teleportero Systems
Some systems utilize the building’s TV infrastructure to distribute the video signal, allowing residents to use their TVs as video intercoms.
Intercom Systems
Enable voice and video communication within a building. These systems require a keypad for dialing and each phone has a unique code for identification. Similar in appearance to door entry systems, they use two cables: one for the control bus and one for audio.
Integrated Telephony
Integration with a private automatic branch exchange (PABX) allows telephone terminals to function as intercoms and communicate with the entrance panel.
Controlled Access Systems
Restrict access to authorized personnel using identifiers like keys or cards. Benefits include difficulty of copying, easy deactivation of lost identifiers, selective access control, time-based restrictions, and access logging.
Components
- Reader
- Identifier (Key, Card, etc.)
- Controller
- Exit Button
- Door Sensor
- Opener
Technologies
- Close Contact
- Keyboard
- Radio Frequency (RF)
- Biometrics
Categories
- Standalone: Controls a single door (e.g., office).
- Centralized Access Control (CAC): Manages multiple doors with advanced features (e.g., anti-passback, capacity limits) and integrates with other services like intercoms and alarms.
Centralized Access Control (CAC) System
Offers advanced features for complex facilities: time-based access restrictions, event logging, temporary access limitations, and automatic seasonal adjustments.
IP Adapter
- Facilitates communication between management computer and the system.
- Connects to the central unit.
- Requires an IP address for network connection.
- Enables remote management via the internet.
- Operates on 230V AC power.
- Uses RJ49 connection.
Alarms and Automation
Supports up to 1000 sensors for automated actions. Sensors are managed through decoders connected to the central unit. Common applications include technical alarms, timed device activation, and door locking.
