infrared motion sensors

  1. I need to pick up a couple of infrared motion sensors to turn on some 500
    watt floodlamps. Can you recommend a good place to buy these individually
    - without any lights already attached?

    Thanks.

    Dave, not get off your subject, but depending on the area of coverage, from
    up to about 60 feet, Optex has several units which are very reliable, and
    there are several on-line stores which can offer you pricing on the units.
    They will follow. Anything longer than 60' you get involved with a little
    pricier unit, such as ProTech (which is a dual tech - PIR/Microwave) or Red
    Wall, which makes both PIR/Microwave and long range Microwave units. Keep in
    mind though, none of these units has a relay built in strong enough to
    switch 120 VAC @ 5 amps. Typically these units are rated at less than an amp
    at DC voltage. An extra relay will be needed to turn these lights on. The
    only reason I say this, and not to assume your not aware of it, is that I
    have seen several installations where this was attempted, both by security
    companies, and electricians. Typically it will work once, and then good bye
    relay.
    You may also want to consider using a control panel to control these lights.
    A control panel can give you better control of the inputs and outputs, and
    allow you to manually check lights for servicing. Just a thought...no
    assumptions.

    any home improvement center will have them.

    Home Depot or Lowe's carries a 120 volt motion detector made specifically
    to turn on & off a light or several lights. It would be in the electrical
    dept.
    where the exterior lights would be displayed.
