Control Inputs

Devices with Control Inputs available

This article describes the control inputs on Exigo in general.

• Control Inputs are available on:
  • System Controller
  • Amplifiers
  • Access Panels (Not EX panels)

• 6 inputs on each device

• Inputs are used e.g. for triggering:
  • General Alarm
  • Fire Alarm
  • Live Speech from external microphone

Configuration

Input 1 on amplifier starts «Fire Alarm» message in «Main Building»

• In Components view open Input Actions
• In System, identify the device and expand to Control Inputs
• Drag the desired Input Action to the on_action or the off_action
• Set relevant parameters in the dialog box that appears

Control Inputs - Monitoring

Control Input

• Conventional inputs have two states:
  • Contact is Open, or
  • Contact is Closed

This makes the control input vulnerable - cable break is not detected.

On System Controller and Amplifiers it is possible to monitor the control inputs. This is done by connecting two resistors as close as possible to the external switch/relay, one in series and one in parallell.

Control Input - Monitored

The resistor connected in series with the external switch/relay shall have a value of 1 kΩ, while the resistor connected in parallel shall be 2.2 kΩ.

Monitored Inputs have four states:

• Contact is Open, or
• Contact is Closed
• Short circuit (error)
• Open circuit (error)
