Generally wired will have "comfort" LED's and wireless will not (to extend battery life).
So if you see a wired bellbox with no LED's that would probably mean the system is dead.
No part of the system can indicate if the system is armed or not.
There can be a system has armed indication but this must only be shown briefly (90 seconds IIRC).
So flashing strobe three times on armed for example is ok.

My opinion is if they have got into the premises to use an umbrella or cloak then the protection isn't correct.
Masking could be done days before a break in so AM is important here.
Been "red spotting again"
Yes, I know the pictures pants but it was the other side of a dual carriageway.

Well, seems the signs are still popping up, spotted some at Wilderspool Morrison's.
Still has the NSI logo on.
Will have to get a shot next time I am round there, not as good at hiding behind a HP bottle as Matt is.
