Does anyone on this forum have an opinion one way or the other for open or closed protocol systems? I know I do.

depends both have benefits. One problem with open protocol is that some clients get anyone to work on a system, dont matter if its right etc as long as its cheap. Closed removes that. We use open as a rule but some high risk sites are closed.

personally i prefer closed protocol - notifier, ziton etc

i find that open protocol can often be commisioned by people who are not engineers, therefore much of the process is guessed at, leaving a raft of problems. also, when using open you can be shafted by both panel manufacture and the protocol manufacture both blaming the other for problems.

With a closed protocol, they will help to correct the problem as they have no-one else to blame!

its all a myth anyway the only truly open protocol system is a conventional panel

Hey All, i have heard that with the new EN54 in 2010 closed protocoll systems are being made non compliant is this correct??

hello stranger!

not heard it but that means nothin' TBH.

where did you here it adam manf or on the net?

C.

from a fire officer down here, have done net searches but cant find anything about it.

Cant see it myself. How could you legislate for that.

Taking it further, why just fire, why not Access, Intruder etc.

Do closed protocols (and panel source code) get fully released to and 'inspected' by any official bodies in order to pass grading requirements etc, or is it just up to the manufacturer to self certify?
