Understanding inputs and outputs in the ATRIUM software

Inputs

Introduction

Typically, inputs are used to monitor the status of door contacts and request for exit devices installed on the controlled door. Inputs can activate relays, reader outputs or bell outputs through the use of macros.

Each controller includes ten inputs which can be connected using zone doubling technology to monitor up to 20 input devices.

All inputs of the ATRIUM access control system including the ATRIUM controller and all door expanders are listed. To access Inputs per ATRIUM controller or door expander, refer to the System Overview section in this article.

From the Dashboard tab, click on the Inputs tab. From this page, inputs may be edited and live status may be displayed.

Modifying an Input

From the Dashboard tab, click on the Inputs icon, select an input from the list and click on the Properties button.

Input Tab

A second input tab will appear when using any of the zone doubling connection methods.

Options

Display Name: Identifies the input throughout the ATRIUM software. We recommend using a name that is representative of the input.
Enabled: When selected, activates the input.
Normally Open: Select this function if you are using a Normally Open device on the input. By default, the inputs are ready for Normally Closed devices.
Input Response Time (ms): This delay defines how quickly the controller will respond to the trigger of an opening input. This prevents any momentary glitch from causing unnecessary alarms. If the input remains triggered for the defined time delay, the controller will react according to its programming. The default value is 100ms. Type a value from 0 to 3,600,000 ms (1 hour).
Input Restore Time (ms): This delay defines how quickly the controller will respond to the trigger of a closing input. This prevents any momentary glitch from causing unnecessary zone closure. If the input remains closed for the defined time delay, the controller will consider the inputs as being closed. The default value is 100ms. Type a value from 0 to 3,600,000 ms (1 hour).

Notes Tab

Use the Notes text field to record any additional notes that may be required. We recommend that you keep a log of what settings were changed and when they were changed.

Save Button

Use the Save button to save changes.

Cancel Button

Use the Cancel button to ignore changes.

Examples of Input Connection Methods

Single (1 Detection Device per Input)

When using this method, only one device is detected by the input. Normally open or normally closed devices can be used. Normally closed circuit shown below.

Here are the different options for a single input configuration:

Doubled (2 Detection Devices per Input)

When using this method, two devices are detected by the input. Normally open or normally closed devices can be used. Normally closed circuit shown below.

Here are the different options for a double input configuration:

Show Status Check Box

When enabled, displays the live status for a period of 5 minutes.

Outputs

Introduction

By default, the outputs (six per Controller and Expander) are used to control the built-in LEDs and buzzers of card readers and keypads. For example, a red/green indicator on the reader will inform the user that access has been granted (changes from red to green), or the reader buzzer will inform the card user that the door has been left open or the door has been forced open.

Each controller includes six multi-function outputs. Each controller also supports up to four 2-Door Expansion Modules, which provide an additional 6 outputs each.

All outputs of the ATRIUM access control system, including the ATRIUM controller and all door expanders, are listed. To access outputs per ATRIUM controller or door expander, see the System Overview section in this article.

From the Dashboard tab, click on Outputs. From this page, outputs may be edited, and manual control may be applied.

Modifying an Output

From the Dashboard tab, click on the Outputs icon, select an output from the list and click on the Properties button.
