(1) Speaker with 20 feet of speaker wire and special phone jack
The Model SPK is a simple plug-in speaker that includes the proper male plug to fit into the auxiliary speaker jack included in the DARD receiver (sounder).
This optional accessory allows for greater volume for noisy areas and also allows for directional alerting.
SPK is also very popular with convenience stores and liquor stores for alerting inside walk-in coolers and the store. The Model DARD (receiver-sounder) has a selectable switch included, that allows the alerting melody to be activated from both the receiver-sounder and the Model SPK at the same time.
