Soteria Twin Input Output Unit

Soteria Twin Input Output Unit

The Soteria Twin Input Output Unit provides the function of two Input Output Units within one enclosure. The two units are electrically independent of each other. There is a DIL switch on each unit to set the address.

Both Input Output units in the enclosure provide supervision of one or more normally open volt free contacts connected to a single pair of cables and a set of changeover relay output contacts.

  • Remote Indication of Concealed Fire Detection
  • High Contrast LED Indicator
  • Wide Area Illumination
  • Audible Indication of Concealed Detection
  • Compatible with Addressable and Conventional Systems
  • Range of Text Legends
  • Integral Buzzer with Mute option

Approvals: AS ISO 7240.18:2015
