    How do you wire a bell/buzzer (like a doorbell) to a motion sensor light, so that if the light is activated then the bell is too (to alert you to someone on your property at night) ?

    • Dave Rongey says:

      Hi Melissa,
      The easiest way to do this and have the flexibility to do even more is to obtain and install a motion fixture that is the X-10 type. X-10 is a technology that uses existing electrical wiring to transmit frequencies to other programmable devices. So an X-10 motion light could be set up to activate others X-10 devices which could then control a buzzer, or more lights.
      If you choose not to use X-10 devices then a motion detector could be wire so that it activates a relay, which could be used to switch a buzzer ON. The wiring, relay and components would be sized depending on the actual buzzer voltage that is used.
      This may help: Using Control Relays
      Be Safe!
