Data, what do you mean by your last comment?

Ok thanks Cubit. That is what I thought, just wanted confirmation. In some ways I can understand the 'feel good factor', as if there is no LED's flashing, then it could just signal a dummy box. Any idea on the split of flashing/non flashing systems?

Hi Cubit, Thanks for the reply. I guess I was concerned that if the LED's flash all the time, then it may signal a potential intruder that the system is dummy, as it could represent a 'live' system, even if the property is clearly occupied. Given you have confirmed that LED's must always flash, then that is fine. All new systems going in now will have to follow this regulation. Out of interest, can there be no LED's flashing, and then just the strobe when set off?

Hi thanks for the reply. So are you saying that the LED's are not allowed to flash constantly? They have indicated that their system has continuous flashing LED's (even if system off, e.g. house is occupied) and then when the alarm is triggered the strobe lights flash.

Hi, First of all I am new here so I hope I have posted this in the correct Forum. I am looking into having a new residential alarm system installed in the UK, and I have been informed by a reputable local installer that there is a European standard that govens the flashing of the LED's on the bell boxes. Apparently the LED's must flash at all times, regardless of whether the system is set or not? Is this the case? I have tried finding this information on Google with no luck, so any help you could offer would be much appreciated. Thanks in advance.
