Dave,
We have cats and the way our house is set up, it wouldn't allow such ... infact the existing alarm is redudant but we keep the outer box there for a deterrent.
I have though, used the...
I remember seeing some nice face plates at the Smart Home Show from Ivory Egg ... http://www.ivoryegg.co.uk/welcome.htm
These may be of use to interface to IDRATEK digital input modules hence...
Allan,
Cortex is extremely powerful and not all the solutions are immediately obvious.
Apart from a whole range of inbuilt functions, 2 very simple tools I use a lot of are extremely useful....
Chris,
I've been running in for 5 years on a dedicted laptop (which acts a printer server and nothing else), Win XP Home and never crashed once.
3 electricity supply cuts in that period and it...
Andrew,
You can probably use a basic thermocouple attached to an interrface which will give a linear proportional voltage output. I have seen some that do 4-20mA but others with 0-10V outputs....
I had the same in a 1910 building. Most of mine were brick with 20mm which I had to chip out ... not too bad by chain drilling a series of holes and then chiselling it out.
The 35mm is for a...
I used to work in access control. Always looking to improve on short range RFID tags (hiprox, mifare, hid etc) as they worked a treat for convenience of being contactless but they were still prone to...
Nad,
My system has a relay module (SRH in my case, but can use any DRB, SRH, DRH, QRI, QRH) across the thermostat contacts. In other words the relay closes like a room thermostat 'demanding' heat...
I'd agree with Jon, I find it re-assuring that something has switched.

Toscal, I am in the North East like Andrew and we have Kielder which means we never have a hosepipe ban. We never get any sun either I suppose :)
IR beams are ideal, but expensive and trigger when...
You would defintely need the isolation as all the interlinked mains smoke alarms I have seen are all floating at maisn potential. I never did work out if the 'trigger' wire came live on detection or...
Chris,
When I got my systme first up and running I did put a DTS in my fridge for a few months.
Why? Well two reasons, one to settle a bet about what temperature they run at and secondly to see...
On ours I have the doorbell driving one of the many spare digital inputs.
When pressed, it starts a macro which plays Big Ben chimes from an MP3 file throughout 4 MFPs and to ensure the person...
Jon,
I use mine to control a Samsung TV, Toshiba VCR, Cambridge Audio DVD, Technics CD Player and Ariston Radio. I haven't had any problems with my MFP learning from each of the respective...
You can also try www.rittal.co.uk who do a very large range of steel/stainless enclosures designed for industrial control apps, but have DIN rails internally fitted.
I'd also have alook at other...
Toscal,
Thanks for the advice. I dont have these, basically I have 6 smoke detectors all wired together and wanted something I could wire into that loop to control power to other items such as a...
I've recently installed a load of smoke detectors that are mains powered (battery backed) and networked using 4 core cable (L,N,E and trigger I presume).
It struck me that this signal would be...
Chris,
Many years ago a builder friend of mine showed me a product which was at the time called "Frost Guard". Essentially it was 3 items, a pressure sensor, a solenoid valve and a box of...
Paul,
Tying the drain shield wire to 0V back at the PSU, but leaving the last position (i.e. last module of the spur) usually works best. This was common practice in both the fire alarm and access...
cheers for all the ideas and info guys. To be honest I want a simple small solution in a box, no extra s/w, no PC, no configuration stuff etc. but thanks foryour ideas.
I did find something on...
I have some large external hard drives in USB caddies. I would like to instead have these acessible to all PCs on my LAN via the ADSL router.
Anyone know if you can get simialr caddies (just the...
ottomate,
Reminds me of how the guys used aniseed balls as fuse timers on limpet mines during the war. seawater took about 30 minutes to get through a standard one apparently :-)
One main problem will be having 2 outputs driving one load ... this is a big no-no in electronics. You would likely damage one of the driving units.
This can be done if some form of switchover is...
Paul,
Thats what I meant, the drives are attached to the laptop which will be running Slimserver. Seems like it is possible then.
Out of interest, if I get the wireless SB3 does it have a wired...
