Perfect; thanks

Thanks, that would work. Maybe someone will chime in that has already done the test. By the way, what is the significance of the flashing orange light at the connector? It seems almost arbitrary the way it flashes. Sometimes 3, sometimes 4, and variable interval in between.

I just installed one of the ELK remote temp sensors with the 7 foot probe and the "silver bullet" on the end. The box is mounted indoors, and I drilled a 1/2" hole through the wall to the outside, then put a 1/2" OD steel tub through the wall, then slid the remote sensor through the tube. My...

Yep, me too.

Enroll the 2nd keypad (the one with the comm error) via the first keypad (the one that is working).

Yeah I saw that while searching. "Not designed for continuous duty applications" is kinda ambiguous and unhelpful. Is it a few minutes? a few hours? what? I wonder what it means exactly, and why the limitation can't be overcome? There are LED flashlights that run indefinitely (til the battery...

Your question got me wondering. I took the unit apart and tested/measured some more. I hooked the strobe directly to a stand-alone variable power supply. The strobe is based on 4 white LEDs, so 90mA would not be out of the question. However, it actually draws about 150 mA at 12VDC in steady...

That might be it. I just looked up the current rating of the outputs and it is only 50mA. For some reason I was thinking they were 200mA. The strobe draws 90mA according to the specs, so it would have been over-drawing. Good thing there are thermistors in the outputs. So I guess I'll have to...

Thanks. Unfortunately my output-3 and the relay is already in use. I did a search on "strobe" but didn't find any discussions on perculariaties with strobes and why output-3 is special. Anyone else remember?

I have an ATW Doberman siren/strobe, but I'm only using the strobe. I've hooked Output 16 to it, and wrote a rule to turn on output 16 for 4 seconds every 15 seconds. The strobe doesn't light. With the strobe disconnected, and a multimeter hooked to the output16 wires, it reads the 12VDC for 4...

Oh, OK. I guess I was thinking the relay energized on violation, but you're saying the (Form A) relay is *normally* energized via the 12V power to the motion detector(s), via the zone wiring, and is DE-energized on violation (e.g. motion detected). Now it makes more sense why the Form A...

Several of the sensors I'm looking at are available with a Form A relay (SPST, normally open), and are usually less costly than cases where the same unit is also available with a Form C relay (SPDT, make-before-break). The cost difference is more than can be explained by the differences in the...

I asked essentially the same question recently. See http://www.cocoontech.com/index.php?showtopic=10079 I may have some different limitations than you, but there may be some info of use to you in the replies. I'm still experimenting, and haven't decided what I'm going to do yet. I have been...

Ah! Thank you very much! That was the missing bit of info I needed. It doesn't appear that Google does a full index (or maybe a full index is not done very frequently), and plus you can't specify the Home Security sub-forum so you have to weed through a lot of things that aren't of interest.

Even using advanced search on 2 or more words, it only spits out a result if the words are next to each other. There must be a way but I'm not finding a description of how to do it...

What is the recommended way to integrate an external 12VDC power supply with the ELK M1G? Assuming the M1G and the external power supply both operate from a 2-prong plug to 120VAC, and let's say it's a 5 amp external 12VDC power supply (w/ on-board current limit to 5A total max) what would you...

Thanks guys, you've given me a few things to try. I'm very limited in the placement of the detector, due to the knee-high to ceiling, and wall-to-wall, windows (and the full-hip concrete tile roof which means pretty much solid wood headers above and between the windows and doors, and no real...

I'm not seeking to get into a debate about it; it's just a choice. The 2.45GHz ISM band is populated with far more unlicensed emitters than the 10.xGHz band. Since Optex makes no claims of tested resistance to for example, receiver blocking/overload from those in-band emitters, and since I know...

Rfdesq: On that Optex MX40, I'm not sure what you mean by 180*, since it looks like a 90* (or 85* according to the specs) pattern. But in any event (and you might have missed this from earlier in the thread) I cannot see a way to put the detector in the corner with the outside wall; I can only...

I'm still coming up empty in looking for a 180* (or nearly that) dual technology motion detector. Also need it to be pet immune but I can't even find a 180* at all. Anyone recall any brands that might have such a beast? I guess the other alternative is two 90* units side by side
