The siren is designed to issue on the object alarm messages about fire. The siren plays speech and sound messages, informing about the event and the necessary further actions. There are three pre-recorded messages: fire alarm voice message, alarm siren sound, test voice message.
Users can record their own sound and speech messages into the siren. The siren operates under control of addressable devices "VS-VECTOR-AP220" and "VS-VECTOR-AP250" and is connected to their two-wire addressable line. In the standby mode the siren is powered from the addressable line, and in the notification mode for power supply is additionally used an autonomous power source - lithium extra battery, which is included in the delivery set.
The siren has two built-in short-circuit isolators of the addressable line.
