The Fortress Wireless Doorbell features a clean, simple design and lets you select from up to 50 different tones and melodies. Simply plug the speaker unit into a wall outlet and mount the doorbell button at the desired location with the included double sided adhesive, no wiring needed! Easily select a tone and adjust the volume with the buttons on the side. When the doorbell button is pressed, the unit will playback the tone you have selected and flash the blue circular light. You can also pair wireless sensors compatible with our S02 and GSM alarm systems to the doorbell. When the sensor is triggered, the speaker unit will playback the tone. You may set different tones for each sensor and even the doorbell button, letting you know exactly where a door has been opened or motion has been detected.
