This is my unique way of testing the alarm activate function on my Fire-Lite MS-4424B fire alarm control panel. NOTE: this is not the proper way to do this so if you happen to have on of these panel do not attempt as you may damage it (I got lucky, nothing happen to mine). The proper way is to wire an initiating device such as a smoke detector, heat detector, or a pull station. Again the piezo sound scratchy do to the camera.
