Tips

For best range, mount the transmitter on a non-metallic surface and avoid placing it near large metal objects or sources of interference like microwaves. The door/window contact can be used on any hinged or sliding opening – just ensure the magnet and sensor are aligned within the specified gap. Pair the transmitter with an M-E MODERN-ELECTRONICS receiver to create a complete alert system; check compatibility with your existing chime if you already have one.
