linking optic fibre to a scantronic 9751?

[mikeald]

i dont know why i must fit a strobe. i am an engineer not a surveyor, i have enough on my plate without having to question my surveyor all the time. The job has been surveyed, now i am asking for advice.

Mike,

Does the surveyor work for your firm? or does he work for the client or insurance company?

[mikeald]

i dont know the answer to ANY of the questions u are asking. all i know is, it has to be done the way i have said. I'll work it out

utilising and using fibe optics is an specialist field and not something that your average (me included) ever touches in his career. the other engineers were only trying to give you constructive advice as an alternative to the expensive way.

if you are insistant on doing it that way i would suggest you contact an specialist (who will have all the correct tool etc).

i know you don't like questions but has the surveyor quoted for the cost of using fibre optic - as per previous posts it aint cheap.

if not then you have a valid reason for asking your company to provide alternative and better quotes.

good luck with the job

If you use the fibre you CANNOT certify the system as the fibre isn't protected / tamperproof.

I'd use the radio option or as has been mentioned earlier, get the specifier to specify what equipment you need to use..

i am not insistant on using the fibre, i agree with all your suggestions entirely, however the customer is always right, and i must conply with their requirements, the system is not monitored anyway. And i have all the neccessary fibre tools as i am an ex bt engineer!!!

Fibre Options do a switch box, the smallest is 4 imputs but its about £1000.00 then whos going to make the fibre ends off, its easy to do if you have the tools but then again a good set off tools would cost you £500 upwards.

Check to see if the fibre is carry any sort of signalling already and if there is a spare port, TCP / IP if the network is already in then you still need a driver and interface.

Scope radio is far the cheapest option, but like dale said there may be data already down it so piggy back on this, and if thats the case then it could be cheaper than a scope pager setup.

No iam not a sales man, but Galaxy do a ethernet module.

Fiber Options also do a data only TX and RX module which can take a NO/NC input. Wire this up to an O/P/relay etc, away you go....

I think the 2 module are around £150-£200 each.

Speak to a guy called Tom Exley at Fiber Options, don't know the number off hand!!

Hope this helps!

if you have the tools then i would go for one of the above - but again will the customer pays for costs incurred doing it this way or is he expecting it as part of quote already supplied - assuming your surveyor did,nt include it in original price?

[bellman]

Yes the customer is always right, but sometimes they are not in possesion of all the facts

How VERY true

Just to clear up a quick misconception.... fibre is very secure... its actually more secure than UTP or any other connections as it cannot be easily tapped (since its light!). This is why for any secure data connections companies will use Fibre links.

Therefore the way to make this connection secure is to allways detect light, and if no light is detected then trigger an alarm.

What about one of these.

You'd just need some method of attaching the input and output devices to the fibre.

Should someone cut the fibre then it'll alarm, and if you want to trigger an alarm, just remove power from the transmitter (easy with a relay on the alarm out)
