    STI Select Alert Sounder & Strobe Alarm

    This controller helps prevent unauthorised use of important devices. The STI SelectAlert is a highly effective way to alert you to unauthorised use, theft or vandalism of important devices. The combination of alarm and super bright LEDs also offers excellent protection for an array of circumstances and allows the user to choose its function. Select-Alert can be used as a cabinet alarm, door/exit alarm, flashing light linked with a push button/switch, tornado siren, burglar alarm or an alert for any type of emergency situation.
