Their engineers produced a document listing which exact part numbers for aiphone brand wire to use with which aiphone models. MOST of them are stranded. It's their brand of cable, and the exact cable part numbers - that their chart says to use.   Note - they DO specify aiphone cable part numbers...

Thanks for the really great ideas folks!   sda - I did NOT think of mounting the 66 block horizontally. Definite lack of coffee there. That would work... BUT... I had completely forgotten that 66 blocks are meant for solid wire, and the aiphone cable I'm using (822215) for the LEF-5's is...

I'm using an elk SWB14 can for an Aiphone (LEF-5's and LE-D's) installation. Rather than daisy-chain all the stations, I'm a believer in home-running everything. So that brings 3 wires per LE-D and 15 wires per LEF-5 back to the elk swb14. The wires for the LEF-5's are 22ga, and the wires for...

Ah, yes, manchester encoding. That's not proprietary :) Matter of fact, I think the UART on the arduino can be coaxed into "speaking" manchester by stuffing the right converted values in to it and fudging start/stop/parity etc. Good info! On the temperature/humidity project, I'll probably...

Well, here's a thought.... Sensirion makes a nice IC (SHT21) that measures both temperature and humidity - all digital. The sensors are integrated, as is the ADC and the I/O interface circuitry. It speaks I2C (as well as PWM, SDM/analog, and volts). It draws minimal current, does RH 0-100% and...

I'd like to have a number coded keypad on my workshop/garage, which is a separate building from my house. It's all controlled by an ELK M1G system. I was wondering if someone had a suggestion for a numeric keypad to open the garage door. I would like one that is a "scramblepad" style, where the...

I would definitely be on board to buy (or possibly help fund development) of something that would basically act like a weather station. I'd want temperature, barometric pressure, humidity, windspeed (and direction), rainfall (can snowfall be done?) and the like. The weekend house is in an area...

My original post was actually brought about while looking at the AB8SS for speaker switch, but I've since gone with a different solution as the AB8SS/ESS seems to be pretty defunct. I was also thinking that there just HAD to be an RS232 or X10 capable weather station. At the country house, I'd...

I'm an elk M1G newbie. I've been pouring over the manuals and I've found my understanding of it's X10 implementation wanting. Perhaps someone can elighten me! I am planning for the PLC connector on the M1G to control both light switches and electrical outlets, specifically: X10 outlets (SR227)...

I would like to select between three or four sets of speakers in the house for music. I'd like my Elk M1G to be able to control this. I've seen some threads about doing this with plain relays, but I believe impedance would be a real issue. The most reasonably priced box I've seen for this is the...

I am new to the Elk M1G, just purchased my system. Here's a summary of what I have: M1GSYS4S, extra M1KP2, SP12F, XEP,150RT, SL1C, PSC05, M1ZTS, XSP, extra can (SWB28), M1RB. Attached are an RCS TR16, FSA-410B detectors, & SRPG2 GB/PIR's. Also involved in the setup is an aiphone system, DVR &...
