About STI Alarm and Chime Products

Alarms and chimes act as inexpensive security devices helping to stop theft, misuse and vandalism.

A medicine cabinet chime and a gun cabinet chime serve different end purposes, for example, but are essentially both security devices to help prevent unauthorized entry.

An Exit Stopper, garage door alarm, other open door alarm or window alert prevents theft from home or business premises, while a wireless chime or alert protects mailboxes, driveways, sheds and fences.
