AARC-EVAC External Interface Unit

External Interface Unit

The AARC-EVAC EIU (External Interface Unit) is a transmitter designed to be wired to a source external to the AARC-EVAC system. That wired connection enables the external source to trigger the EIU, which sends the alarm or alert to Evac Controllers. Any one of the alarms or messages on the AARC-EVAC system can be configured to be triggered by an EIU Unit. The EIU is handy for incorporating existing alert systems or specialised alert equipment like fire panels and door alarms with an AARC-EVAC system.
