An emergency warning and intercommunication system is required for some Class’s of buildings, in accordance with the Building Code of Australia. They are installed for the purpose of enabling the orderly evacuation of the building.
The EWIS will provide:
If not responded to within a prescribed time from initiation the automatic Evacuation sequence shall commence. The prescribed time shall be established to suit the particular building. The majority of EWIS Systems are programmed to roll-over from the alert to the evacuation tone within 3 minutes.
