Notifier I-2000 Emergency Warning and Intercommunication System (EWIS) has been designed to facilitate the orderly and speedy evacuation of a building in the event of an emergency. This procedure may be initiated automatically by a fire alarm system or manually by a break glass call point.

The I-2000 may be used as a fully automated system or it will allow Fire Wardens to easily control and coordinate an evacuation using the dedicated emergency telephone network.
