Question on Motion Detectors
Do they work 24 hours or just at night? That is, will the light sense
motion and turn the light on even at noon? Dumb and curious. Geezer |

Question on Motion Detectors
Motion detectors used on their own in a circuit, such as in an area
intrusion system or burglar alarm, will always work while the system is armed. Motion detectors used in conjunction with a day/night electric eye, of the type used in outdoor floodlights, will work only when the electric eye senses that the ambient light is low enough to turn on the floodlight. The motion detector and the electric eye are in effect two switches wired in series between the source power and the floodlight. If either switch is open then the floodlight remains off.

So just bypass the electric eye and it will work 24/7 4 U. |

Maybe tonight after dark, I will know the answer for sure. Thanx agin Geezer |

I thought it used infrared and that it measured the IR coming from a warm body. When I had one it worked at all times. Thanx agin Geezer Remove NOPSAM to email me. Please let me know if you have posted also. |

Question on Motion Detectors
Every one that I have seen, the motion detector works regardless of
light level. Also, every one that I have seen that is used as a light controller also have a photocell, so that for the light to go on it must be dark and motion must be detected. The motion lights I have used also have a slide switch that can be set to test mode, so that you can adjust and aim the motion sensor in daylight. |
