    ADT Safewatch Pro2000 of 25years died

    I sent you a PM, just need a response so I know where to send the wire. Miraculously, my wire "scraps" were where I remembered and I didn't have to take half a day searching. I measured the 50' quick and dirty, so it's probably more like 60+ ft. Expect to have a learning curve when it comes...

    ADT Safewatch Pro2000 of 25years died

    Yes, you're right, it looks like you need to replace the cable from Panel to Keypad. Almost everyone, including ADT, uses 22/4 = 22AWG, 4-conductor. Most dealers use red-black-yellow-green, but ADT used blue instead of green. There's long-standing disagreement over whether solid or stranded wire...

    Caddx Ranger 8980 power light out

    In the alarm industry, when we refer to a "Control Panel", we're talking about the "brain" of the system, a PCB located in a steel cabinet somewhere, usually in some out-of-the-way place like an unfinished basement, closet, or utility area. What you're talking about is 3 Keypads, the interfaces...

    ADT Safewatch Pro2000 of 25years died

    You will need a Honeywell 6160. That's a two-line Alpha KP, which you'll need to program the panel. Remember to have the panel powered down when you connect it. Your old SW-2000/ Ademco Vista-20SE panel didn't use keypads with different addresses, which means that your new KP will need to be...

    ADT Safewatch Pro2000 of 25years died

    T4 and T5 are nominal 12VDC power for peripheral devices, i.e., keypads, motion and/or glassbreak sensors, RF Receiver (5881 or 5882), Hardwired Expansion board(s), and a few other possible devices. Any one of those devices could have been zapped by the lightning and might be drawing down the...

    ADT Safewatch Pro2000 of 25years died

    Okay, so you have 19.44 VAC power on terminals 1 & 2. The keypad is powered from terminals 4 & 5, and I'd normally expect to see ~12.5-13.5 VDC there, depending on the load drawn by peripheral devices, including keypad(s). What are you reading at Terminals 4 & 5? Also, what's the status of...

    Faulty Electronics and Ethical Practices

    Coincidentally, I just recently learned that most (all?) relay contacts are made of 30-50% silver. I'd always assumed those shiny points were nickel, and had never bothered to look it up. Those points are tiny, but there are so many relays on so many PBCs, and they add up--breaks my heart how...

    How do you program the 10 digit alarm number to connect to police station ona CS-250 system

    Yeah, I've made some colossal errors from being in a rush. It doesn't surprise me that you had a voice dialer in '89: I didn't feel the need to elaborate earlier, but most police departments didn't just outright discontinue receiving calls from alarm systems in the late 60s-early 70s, but they...

    How do you program the 10 digit alarm number to connect to police station ona CS-250 system

    I check this forum most days, don't know how I missed this thread yesterday and earlier today. My apologies. Richgolf, the Aritech CS-250 was marketed in both North America and UK & Ireland, that I know of. The answer to your question might depend on where you are. IF you're in the USA...

    Liquid Volume Measuring Project

    Not to mention, this forum is international, with a lot of posters from the USA. I'm guessing your 20 to 50 degree range is Celsius rather than Fahrenheit. Sorry, we Yanks are still stuck with that. :(

    i have problem in my electric pressure cooker it just trip whin make on

    i once had that problem with an electric iron. When I opened it up, I found a screw had come loose and was stuck between two electric terminals. If you can open the cooker and look, you might find an easy fix. For future reference, it usually helps to name the make and model of the device.

    Please help me calculate wire temperature due current

    You are correct, Alec. Years ago, some of our field techs were careless about keeping their supply of fuses stocked for house calls. When they came across a blown 1A to 5A fuse for which they didn't have a replacement, they'd wrap one or more strands of wire around it (a single strand from a 22...

    Wanted: Historical Alarms systems and parts

    By coincidence, I'm in the process of clearing out all my old alarm parts, but I suspect my oldest stuff goes back to, maybe...50's? My oldest panel, is a pristine never-used Ademco Model 110 (like a Model 100, but with a DPDT holding relay instead of the #100's SPDT relay )--I got into the...

    Ademco Vista 20 - open circuit intermittent beep from panels

    It's unlikely that your 1361 transformer is causing the problem. The "Open Circuit" message on the Keypad display almost always means there is a communication failure between the Control Panel and a Keypad, most often a data wire that has come loose or poorly connected, either at the V-20 Panel...

    Ademco Vista 20 - open circuit intermittent beep from panels

    The quick answer to stopping the beeping from your keypads is to unplug both the battery and the transformer at the Control Panel. The Control Panel (or just "Panel" is the main Printed Circuit Board (PCB) located in a steel cabinet somewhere. I assume I don't know what you mean by "unplug...

    Wire Size for Security Camera

    I stand corrected, Tha fios agaibh. I was drawing on my own 40+ years of professional experience of working with low-voltage systems for different companies, mostly alarm systems but also a little bit of access, video, intercom systems, and even phone lines and doorbells. I'd always assumed that...

    Interlogix NX-8v2, Double Zoning

    Yes, I saw. That's why I asked you to post there. I've been reading MrRonFL's posts for about a decade now and he has a wider range of experience than I do. I'd follow his advice, and put the double-zone resistors on zones 1-7. I didn't study the NX-8v2 manual thoroughly enough to find that...
