Once any loud household sound is detected (such as a baby crying, kitchen timer, security alarm, etc.), this transmitter sends a signal to any Medallion Series receiver, which will alert you with flashing lights or vibration.

With the Medallion Series you get million-code technology, which means your system will never get a false alert from a neighboring radio frequency signaling system. It's ideal for apartments, dorms, condos and hotels, as well as single-family homes.

Features:

• Adjustable sensitivity switch
• Sound delay threshold prevents it from being activated by brief noises, such as a door slamming
• Up to 500ft range
• Uses 2 AA batteries (included)
• Low battery indicator light
