WPAS Siren Control


The WPAS satisfies the requirement for Mass Notification, Alerting and Public Address and Siren Systems in smaller communities, university and sports campus, buildings and malls, camping sites, training facilities and many other applications.

The WPAS units located throughout the area to be covered are controlled by WSB radio base station or RS-485 data circuits connected to the DT-11 Operating Console.

The WPAS can be used for single stand-alone installations and in larger wide area networks. Siren warning signals and live voice messages can be addressed to the total system, selected groups or individual WPAS.

A hand portable GP 380 VHF or UHF radio transceiver can also be used to remotely control a WPAS system.
