Indoor Station for ABB Door Entry Systems

Designed like a traditional intercom station, the ABB Audio Hands-Free Indoor Station with 4 Buttons gives residents a convenient way to answer intercom calls from outdoor stations in their ABB Door Entry System, as well as other hands-free indoor stations (room-to-room). When the station rings, press the answer button and start talking! The open speaker and microphone provide clear audio communication, and the four pushbuttons make it easy to access other functions in the system, including triggering a door lock release, making a door status check, and calling a Guard Unit.

  • Provides audio communication with outdoor stations
  • Supports room-to-room communication
  • 4 buttons for communication, unlock, light, and mute
  • Light button is optionally customizable for other functions
  • Up to 5 different ringtones differentiate call sources
  • Adjustable volume for speech and ringtone
  • Surface-mounts with integrated bracket or optionally flush-mounts

4 Buttons for Various Applications

The station's four buttons are labelled and intended to control the following functions:

  1. Communication: Answers and ends a call. In standby mode, press this button to enter the communication menu.
  2. Unlock: Press this button to open the door at any time.
  3. Light: Switching a light on/off, or may be programmed to control a different function, such as call to Guard Unit, room-to-room intercom, or open a second lock.
  4. Mute: In standby mode, press this button to mute the ringtone of the indoor station, or hold the button to mute the ringtone of all indoor stations in the residence. When a call is coming, press to reject the call. During the conversation, press to mute microphone. The LED illuminates to indicate mute status.

5 Ringtones & 4 LED Indicators

The station makes it easy to know what's going on with your system. You can set up to five different ringtones to differentiate between various sources of incoming calls, such as your main outdoor station vs your Guard Unit. LEDs also provide system status indications.

Installation Details

The ABB Audio Handset Indoor Station connects to the System Controller (sold separately) using two wires. Multiple indoor stations may be daisy-chained together. You can either surface-mount it to the wall using its screw holes, or flush-mount into an ABB Flush Mounted Box (sold separately). After the station is wired into the Door Entry System, it simply snaps into the box.

NOTE: Requires 2-wire connection to a System Controller, sold separately. Also requires use with at least one outdoor station that includes an audio module OR at least one additional hands-free indoor station. Installation hardware not included. For indoor use only.

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.
