Pre-Assembled Outdoor Station for ABB Door Entry Systems

The ABB Video Outdoor Station with Keypad is a pre-assembled custom outdoor station for the ABB Door Entry System, facilitating quicker installation for common applications. The four-module station includes the Audio Module with Speech Synthesis (M251024A-A), Camera Module (M251021C), Keypad Module (M251021K-A), and Display Module with Card Reader (M251021CR/M251022CR), as well as the required 4-module Aluminum Faceplate (51024CF-A). This configuration allows a visitor to initiate a call with an indoor station/residence by entering a call code or choosing a name in the directory, to talk with the resident, and to unlock a connected door lock with a proximity card/tag, while the resident can view visitors through the camera from a video indoor station.

  • Includes faceplate and 4 modules: Audio, Keypad, Camera, Display
  • Provides two-way communication with indoor stations
  • Built-in speaker, microphone, and two door lock terminals
  • Activated by indoor station or calling code/name
  • Live video feed viewable on video indoor station(s)
  • Built-in card reader unlocks door or triggers Wiegand output
  • Installs into a 4-module ABB Flush Mounted Box

Audio Module Features

With a built-in speaker and microphone hidden behind a solid aluminum face (no speaker holes), the Audio Module provides two-way communication with indoor stations and can optionally trigger an output in your ABB Door Entry System. Communication can be established either by the resident at an indoor station, or by the visitor upon pressing the built-in pushbutton. This model also supports speech synthesis, allowing it to play a custom voice message according to system status.

  • Supports speech synthesis to play custom voice message
  • Adjustable lock release time and speaker volume
  • Integrated optic sensor for day/night mode

When a visitor initiates a call to an indoor station, one of the Audio Module's three status LEDs indicates whether the call is successfully made or the system is busy. If the call is successful, the call LED illuminates. A second LED illuminates when communication is possible, and the third LED illuminates if the resident has remotely unlocked a connected door for the visitor to enter.

The module allows you to connect an electric lock for remote door unlocking. No independent power supply is needed for the lock. A second terminal for a second lock is also available. The lock release time is adjustable for security.

Keypad Module Features

The 16-button aluminum keypad lets you attach a calling code and/or a calling name to each indoor station or each entire residence/office in the system. This allows a visitor to easily call the precise location desired. They can either enter a known calling code, or search through your directory of names at the included Display Module to find the person/location they need to call.

  • Stores up to 3,000 names in built-in memory
  • Backlight ensures clear visibility at night
  • Supports universal or individual password(s) for directory/call access

To initiate a call through the keypad, a visitor will first need to enter a password if you have set a password (optional). Passwords can be either universal/public or customized for individuals (supports up to 6,000). If a visitor repeatedly enters an incorrect password, the keypad will lock.

Upon entering a correct password, the visitor can begin to initiate a call by either entering a calling code or choosing the desired name to call. A name can be chosen either by inputting letters of the name or by searching through the directory and choosing a name.

The keypad may be programmed to initiate the call either automatically once a code/name is entered, or manually by pressing the (1) button after entering the code/name.

The keypad has 16 buttons total, including:

  • (10) Numbered/Lettered Buttons (0-9, A-Z)
  • (2) Arrow Buttons (Up, Down)
  • (1) Pound Sign (#) with Enter Arrow
  • (1) Star Sign (*) with Backspace Arrow
  • (1) Telephone Button
  • (1) Attendant Button

Camera Module Features

The live video feed from this wide-angle camera can be viewed anytime through a video indoor station (sold separately). Built-in IR lighting ensures you can see clear images even at night, and a built-in heater prevents fog from covering the lens and obscuring your view. Furthermore, the camera's scratch-resistant and fire-resistant finish helps prevent vandalism.

  • Wide-angle camera with manual view adjustment
  • Built-in IR lighting provides clear night vision
  • Temporarily disable lighting for discreet surveillance
  • Supports either PAL or NTSC video signals

Display Module Features

The screen displays digital customized messages, codes, or names, perfect for use with the included Keypad Module. Additionally, the built-in card reader can be used to unlock a connected door lock or trigger a third-party Wiegand access controller. When a visitor or resident waves an authorized proximity card/tag (sold separately) in front of the module, the lock/controller is activated.

  • Large screen displays programmable digital messages
  • Built-in card reader unlocks door or triggers Wiegand output
  • Supports up to 3,000 different proximity cards/tags
  • On-screen menu allows local card registration/deletion

The reader is compatible with third-party NFC/IC cards and tags, not included. Choose between either an ID card reader or an IC card reader. The ID model is compatible with third-party cards using the 125nKHz frequency, while the IC model works with cards using the 13.56 MHz frequency.

Through the on-screen display menu, you can locally register/delete up to 3,000 different cards/tags. When connected to the Audio Module, the card reader can also trigger different sounds, one for an accepted card and another for a rejected card.

Installation Details

The ABB Video Outdoor Station connects to the System Controller (sold separately) using two wires, and installs into a 4-gang ABB Flush Mounted Box (model 41024F, sold separately). After the modules are wired into the Door Entry System, they simply snap into the box, and the included faceplate snaps over them onto the box. The box can be flush- or surface-mounted with accessories.

About the ABB Door Entry System

Also known as the "Welcome" system, the Door Entry System is a first-of-its-kind modular intercom and access control system that offers one flexible solution for any intercom and entry security application.

How to Build Your System

Every ABB Door Entry System needs at least two components: a System Controller (either standard or mini) and an Audio Module (any variation). With these two foundational components, the system can be expanded and customized as needed. Additional system components may include:

  • Custom Modular Outdoor Stations
    • Audio Module (speaker/mic, with or without pushbuttons)
    • Pushbutton Module (with or without built-in card reader)
    • Keypad Module (with or without built-in card reader)
    • Display Module with Built-In Card Reader
    • Camera Module
    • Nameplate Module
  • Pre-Assembled Outdoor Stations
  • Hands-Free Indoor Stations (with or without video screen and/or induction loop)
  • Handset Indoor Stations (with or without video screen and/or induction loop)
  • Guard Unit (specialized station for security monitoring)
  • Mobile Devices (requires Telephone Gateway and/or IP Gateway)
  • Telephone Gateway (for integrating mobile or landline phones)
  • IP Gateway (for enabling remote Internet access)
  • Switch Actuator (for relay control)
  • Camera Interface (for connecting third-party analog cameras)
  • Elevator Lift Control Relay Module (for elevator/floor access control)

Other accessories are also available for installation and connection. Most notably, in order to build a custom modular outdoor station, you will need to select the modules you wish to include in the station, and then match the number of modules to the appropriate size Flush-Mounted Box and Faceplate. (Flush-mounted boxes support optional surface-mounting in addition to flush-mounting. When surface-mounting, a Rain Hood is also required; only optional when surface-mounting.) The screwless, snap-on design of both outdoor and indoor stations makes installation a breeze.
