This vibrating unit is a great accessory for the Rodger Wireless alarm. Simply place this unit between the mattress and box springs near the head of the bed. When the alarm is triggered by moisture, this unit will vibrate to assist in awakening the user. This bed shaker can be placed up to 9 ft. away from the alarm receiver.

Note: This vibrating unit only works if the Rodger Wireless receiver is plugged into an outlet, not while it's using batteries.
