[Roller Shutter 1 Or 2 Contacts?]

Aye, most doors we see are either fastened down from the inside, or locked halfway up, so popping them out would be hard going?

Still, one site we had a hole cut IN the door. Big cat flap type job, wish I got a pic!

Unlucky for them there was AX across the door and D/T in loading bay

[Roller Shutter 1 Or 2 Contacts?]

Same tech also

We tend to fit one, never been pulled up about it, then either DT, or AX across the door

[Gamma 7]

tat imo, no different to b&q specials at premium prices.

For those prices of the complete kit,, you could have one professionally installed by an nsi/ssaib co. That includes piece of mind, warranty & insurance approved graded system.

[Oldest Panel]

We've still got a load of Logic 4's and old Bentleys out there under maintenance, got a REALLY old ADE panel in our stores, boss wont let it go, cream metal cased thing with a KS, i'll have to grab a pic!

First system I installed myself was probably an Optima!

[Texecom Premier]

Shouldn't have to though. The 'company' should have set it up properly in the first place.
