RH100 Sonic Alert Sonic Siren (Remote Horn)

This Remote Horn is adjustable! When a doorbell, telephone or baby cry transmitter is activated, the remote horn emits a loud low frequency, audio horn sound (now adjustable from a loud 78-85 decibel low frequency to a high 113 decibels). The adjustable tone ranges from 200-2,000 Hertz. The RH100 plugs directly into your wall outlet and doesn’t need the SA101 or SA201. This adjustable remote horn will alert you by sounding an adjustable tone and volume control, which allows you to select the most effective audio alert sound combination.
