Please take 5 minutes to complete the BRE National Security Survey 2017. The survey will be open for responses until 31st October 2017. We will start to share the results at our event 'Planning Today for a Secure Tomorrow' on 2nd November 2017. You can find out more about the event at: Thank you for your time BRE

Nah man sounds like blag
datadiffusion replied to KJDK's topic in Guest ForumI mean if you stick your true RMS fluke into the socket you'll read about 240v.
RT @PendletonNW: Can you believe this took place - it's like watching something from You've Been Framed....lol https://t.co/nxLJs0Rpi0
What you think is mostly measured? don't understand this stuff man
datadiffusion replied to KJDK's topic in Guest ForumThe UK is officially 230VAC like the rest of the EU, but this is a nominal figure, which allows an upper tolerence limit within which 240V (which is what you'll mostly measure 'in real life') is quite acceptable.
Why not? Think about it the relay if always on will still have contacts that are open , which would close when the alarm is open
KJDK replied to KJDK's topic in Guest Forum@al-yeti : Thank You for your answer. I did not know that. I'm learning things as I go along and thus has never had to use a relay before. @James Wilson : I think most 12V sensors have a rated operating voltage of 9-15v .. some even 6-15v ... I'm guessing that 12v is just a common label. Just like 220v is actually 240v and UK 240v is actually 250v or is it 280.. But I'm not from the UK nor an electrician so I may be wrong. I expect the alarm system has a step-upper build-in, in order for it to be able to provide 9v while running on a 5v standard samsung usb adapter. The system I have is called "GSM/IP Alarm System" - its a square white box with touch keys - it supports WIFI/GPRS/GSM, Has 39 zones and 4 hardwired zones. I've gone for wired glass break and reed sensors and a couple of wireless door sensors that'll probably get replaced by more wired reed sensors. I'm unsure weather I'm allowed to post a link for my DIY system - It's a Shenzhen generic sold under different labels I think. If the N.C. connection in mention is for controlling a relay then would it not be possible to connect the following things? Here is a little mashup that I'm hoping a bright mind can tell me how to connect properly.
I've tried to fault find as best i could, run through diagnostics menu to check batteries and signal strength as it's a wireless system and all seems good, however i will have to consult the manual a bit more. Unfortunately i have this beep every minute and it's driving me mad. I don't know if i should power down the system, remove all batteries.
