I would suggest you have programmed the codes incrorrectly somehow.
You can default the codes. If you check the manaul it will tell you how.
Alternativly if you let me know your order number ill send the procedure to your account email.

You will need to take an output from the panel. What inputs doe you have to trigger the shutter, id assume the shutter is designed to be held open by the fire alarm normally.
I would suggest you use the aux fire output on the panel. What panel is it?
you 'could' do it this way but id suggest its a problematic way.
A better way would be to use a 240v relay and connect this to the incoming supply. When that opened it could open your gates straight away. If you would like a delay then id add a timer to hold off the relay.
an external warning?
Well the simplest would be a mains relay from the light and an external sounder and power supply.
But id recommend the gjd system, or an full control panel would be better.
Depends on their budget and needs really.
its not 180 deg, i dont know of a single head pro unit that is. Its usually only the low qualioty stuff that is.
but it is 12v, with adjustable times etc
Have a look at the product page download the data sheet
12v dc?
id so the only unit that will do 180 degs is the voltek twin head. But this doesnt have adjustable times etc. Apart from the opal elite (gjd) none have a programmable time this is usually done by the controller
