    thermostat to run light bulb or small heater to prevent freezing

    Paulcalif, I'd recommend you set the thermostat to turn on the heater considerably higher than a couple of degrees above freezing---there's usually a substantial time lag between the heater starting up and the room temperature being affected, depending on the size of the room and how airtight...

    versitile microwave sensors/detectors

    Steve, I suspect Earl is being a little facecious here....what he's looking for is not too far off from what some of our customers expect us to deliver in the alarm industry---only they expect it to cover their entire home, garage, cars, grounds and airspace for $99. :rolleyes:

    Caddx NX-8E Alarm System - Fire Zone Light On

    GAAAAHHHH!!!! :eek: Kevin, STOP!! If it's not already too late, stop taking things apart and/or buying things you don't need. The first thing you do with an alarm system trouble is read the User Manual/Owner's Manual. If that does't tell you what you need to know, then get the...

    anyone knw photoelectric smoke detector circuit？

    No! Don't use it in your building. Not unless you're using it in addition to a UL-or-equivalent-rated smoke detector. It's okay to put it up as a project experiment, but it's NOT okay to use a first-time homemade project as a life-safety device.

    step down 10v to 5v with a resistor?

    What Steve said. A slightly longer answer is that you might actually get a resistor to work but at the very least you're risking a drastic reduction in the lifespan of your motor. The arrangement could have it operating at currents it wasn't designed for, for small increments of time, but...

    Led's and ohms law (newbie question)

    The power source you use could make a difference if it's not strictly voltage regulated. I work a lot with "12" VDC power sources, i.e., DC power supplies with a 12V lead-acid battery backup attached. The 12VDC rating is "nominal" and approximate. The output off either the power supply or the...

    Aritech CS-250 alarm

    Replacing a PIR does not require a reset. Is the PIR not working? Or is the zone it's on showing as faulted / open at the keypad? I wasn't able to locate an Aritech CS-250 Installation manual with a quick search, but since you didn't ask for a User Manual, I assume you have one. It will tell...

    wireless Alarm issue - SX-V

    Hmmm....to be honest, I don't remember ever seeing an "HH" in the display, nor in the Installation & Programming manual. My own manual is not at hand, but if you programmed your panel, you obviously looked through yours. It's not the tamper switches--they show up on the CPU sensor number...

    wireless Alarm issue - SX-V

    Hi gsun, just to get our terminology straight: There's no such thing as an SX-VI. The Rollins name for the SX-5 (SX-V) is the "System 6" (System VI). Notice I don't pretend to count in Latin like ITI and Rollins. I prefer to write using the numerals of the language I write in. Saves...

    Wiring a Crow Genius 10 PIR

    I haven't kept up with Napco's newer panels, but it's possible that the manual is correct and complete and you're working with a later revision. Also, Napco programming is not really DIY-friendly. The instructions are not linear, and the "incompleteness" you experienced may well have been...

    PC5010 Alarm

    Hi, jpfen, I sent you a PM. Your PC5010 can be defalted to factory values as a last resort. If it spontaneously armed after a power outage, there's a good chance it needs a new battery in the control panel. Once you get the manual and check to see the procedure to reset to default settings...

    How do I change the number my alarm system dials?

    Drat!! Again. It does sound like ADT has locked you out of the dialer section of your programming. At this point, the only ways to get your system to call your cell phone is (1) Replace your control panel, which would involve programming the new panel completely from scratch...

    Simple (4001 Based) Alarm Circuit

    Good grieficus! That's a complicated circuit for something to beep a few seconds when the door is opened. I've got a jar full of surplus Sonalert alarms. I'll be happy to send you one if they don't have any handy at your local Radio Shack. They sound when anything from 1.5VDC up to...well...

    Is electronics completely random?

    LOL! Good reply, Steve. I like your approach to the question.:D

    vista 20 p problem

    Whoops! Okay, I neglected to say something critical: :o When you press 1 and 3 simultaneously, you need to hold them pressed for 3 seconds. See if that works. Btw, do you have another keypad besides the 6150?

    Wiring a Crow Genius 10 PIR

    That's correct on all counts. The e/e follower is an internal zone and the chime responds to perimeter zones. Go ahead and follow the programming instructions carefully. If you have a question, I'll probably have to go study the manual myself. To be honest, I haven't programmed a Napco in...

    Free Engery

    You and I are on the same page, Sam. PM machines can be an excellent chance to explore things you aren't clear on, or sometimes discover things you didn't know about and didn't know you didn't know about. I applaud people who open the inquiry on perpetual motion machines. But, like Steve...

    How do I change the number my alarm system dials?

    Drat!! Okay, Brian, I just scanned back over the thread and I may know what's going on. The clue was that ADT installed it and presumably terminated an account with that system. If they download in the process, they get cute sometimes. But let's not jump to conclusions. Try this: Go into...

    Free Engery

    I like your definition of "Free energy", Steve. I was thinking along the lines of petroleum and coal not being "free", even though we (humanity) didn't pay for them, because they are linked to the land they're on/under, and virtually all land is considered to be "owned" now, so whoever owns...

    Wiring a Crow Genius 10 PIR

    Okay, have to remember they may be using a filter. Sensible precaution to hold the spamming down. I'll try to PM again with a different tack that doesn't involve posting a URL.
