Review RADIOSHACK Safe House Ultrasonic Alarm Hong Kong Radio Shack Tandy Corporation

The Radioshack 49-306 Safe House Ultrasonic Alarm, also known as the Hong Kong Radio or Tandy Ultrasonic Alarm, is a compact and discreet security device designed to protect your home or office from intruders. This alarm system uses ultrasonic technology to detect sounds above a certain frequency, making it an effective deterrent against burglars who seek to avoid traditional sirens and alarms.

Measuring just 3.2 inches in diameter and 1.6 inches high, this ultrasonic alarm is small enough to be placed in various locations around your property without drawing attention to itself. Its sleek, white, circular design blends seamlessly with most decors, allowing it to function as both a security measure and an aesthetic addition to your space.

The 49-306 Safe House Ultrasonic Alarm comes equipped with an adjustable sensitivity control, allowing you to fine-tune the device to your specific environment. This feature ensures that the alarm remains quiet when there is minimal background noise, while effectively sounding the alarm when it detects suspicious activity.

One of the most notable advantages of the Radioshack 49-306 Safe House Ultrasonic Alarm is its ability to operate on both AC and DC power sources. This versatility allows you to use the device in various locations, without being limited by the availability of electricity. The alarm requires four AA batteries as a backup power source, ensuring that it remains operational even during power outages.

To arm or disarm the alarm, simply press and hold the test button located on the top of the device. The alarm will emit a series of beeps to indicate its status. When armed, the device will activate and emit a high-pitched ultrasonic sound when it detects sounds above its sensitivity threshold. This sound is inaudible to humans but can be heard by pets and intruders, making it an effective deterrent.

The 49-306 Safe House Ultrasonic Alarm also features a built-in LED indicator light, which illuminates when the device is armed and flashes when it detects sounds. The alarm can be easily mounted on a wall or ceiling using the included mounting hardware, providing added security and convenience.

With its compact size, discreet design, adjustable sensitivity, versatile power options, and effective ultrasonic technology, the Radioshack 49-306 Safe House Ultrasonic Alarm is an excellent choice for those seeking an affordable and reliable security solution for their home or office.
