This thread is for any EE or advanced hobbyists here...   I have a situation where I have some 3.3k EOL installed in nearly impossible to access locations and I want to change to a different panel brand. Most panels are in the 1-2k range.   One option I am considering is the Bosch B Series that...

Looking for opinions on panel options for DIY in 2022.   I've been putting off replacing my defunct Interlogix UltraSync while hoping that some company would update their products OR a new company would appear with a modern solution. Notice that was what I was apparently looking for the first...

The COSMOD2W comes up repeatedly in this forum and frequently in regard to using more than one of them for multiple zones. Forum members graciously explain the issues involved and indicate vague/unstated hardware and/or programming workarounds. All of us would benefit from more concrete details...

https://www.dsc.com/powerseriespro/   Appears to have been launched within the last year. Looks to be an upgrade from NEO.

In reading the COSMOD2W manual I noticed this jewel: "Note: CO Trigger may only be used with UL 864 panels that have been evaluated to confirm CO services".   I know others here have used this with Elk and older DSC. I haven't found that either are UL 864 listed. Nor is my UltraSync.   I'm doing...

I am going to be using COSMOD-2W for smoke/co.   I'm looking at the NX-8e manual. Nothing specific to CO detection. There is a "Gas detection" zone type. But there appears to be no aux relay event type that matches it!  

Anyone have a setup using those components?   I'm wondering about the current calculations. The DSC 18xx PGM only supplies 300ma. COSMOD2W says 121ma@12V in alarm; I'm going to have 2 of them so 242ma.   The 2WTA-B specs are confusing to say the least. The 2WTA-B says 130ma "max" but 30ma in...

Anyone know where to look for reasonably priced (probably fiberglass) underground hand hole / pull box / vault?   I see lots of information about them from many manufacturers but, of course, they are all oriented to volume purchases and large commercial distributors. I'd rather not have to go...

This is a copy of a post I made over at Loxone Forum in case anyone here is interested. I present my design for an advanced and highly scalable interface to dumb switches (like the Wattstopper LVSW) with ethernet communication to Loxone or any master automation controller. Similar to Elexol...

Its been awhile since this topic came up on this forum. What are people doing these days?   My new construction attic will have sprayed-on foam insulation and blown-in on top of it (Minnesota). Simply leaving ceiling speakers exposed in the attic won't work.   In searching for a back box I've...

I've designed a pair of boards that allow me to control an AC ceiling fan. One can be used standalone along with any digital/relay interface (one for each of possibly 4 speeds). The other adapts to 0-10VDC control.   Both have been built and tested with Loxone and a Hunter ceiling fan (120V). I...

I'm planning for new construction and intend to install a Loxone automation system. Loxone has some security capability but is inadequate for my needs. So I'm looking for the right type of dedicated alarm system with excellent automation integration capabilities.   By "right type" I mean one...

Looking for recent info on this.   Anyone using a hardwired motor to do lift and tilt for relatively large horizontal/venetian wood blinds?   It seems Somfy can do this with two separate parts - the normal tube for lift and a separate tilt motor (which seems to be intended for battery use).  ...

The Carrier (SYSTXCCNIM01) or Bryant (SYSTXBBNIM01) NIM (Network Interface Module) interfaces the Infinity/Evolution systems to ventilators and/or non-Infinity/Evolution A/C. I picked up a reasonably priced Bryant NIM on eBay and connected it to my Carrier system and it works fine (be aware that...

Thought I would share what I have learned. This data is from a Broan ERV140TE. I suspect a Broan HRV150TE has the same controls. It appears these may be the same as Venmar E15 ECM ERV and HRV and likely similar vanEE products. They are all the latest generation ventilators with energy-efficient...
