Multiple Reed Contacts Fsl

[BveshPatel]

This topic maybe exhausted but I couldn't find s definite answer hence why I am asking the question ;

On a scantronic 9651, software version 4 can you have multiple magnetic door contacts on the same zone using FSL?

I have currently tried this however I am getting tamper each time a contact is opened and wondered what could be the cause as I have tripled checked the terminations and can't seem to find the fault. I am able to exit engineers mode without any tamper however when a contact is opened it goes directly into tamper, however if I have just one contact connected it works fine. I am using 4k7 for alarm and 2k2 for tamper.

No version of Scantronic allows multiple FSL on one zone, at least, not without modified wiring as per the manufacturers instructions i.e Elmdene, Knight etc...

Galaxy I believe does allow multiple 1k/1k contacts on one zone with no modification.

afiak its only gal that does this

There maybe a little bit of a confusion here. It's not multiple FSL but rather two contacts on a single zone is using FSL/EOL where the last contact has the 2k2 resistor in and the first contact only has a 4k7 resistor.

That wouldn't work anyway unless you mean zone doubling. Only panel I know that does this is the cpx as it's never used anymore

Sound like you have them wired wrong. check the manual again should have single leaf and double leaf wiring diagrams. You'll need to bring 1 leg of the first resistor across with another core.

Would it matter if the contacts do not have a specific tamper terminal? I am using the CQR 1 Reed 5 Terminal Surface Contact Grade 1

No, just loop in.

But by using proper contacts like Knight

Its all done for you anyway.

i wired 4 knights eol on one zone last week (2 sets of fire doors, linking 2 zones together in the control panel) fun and games were had then, never again.

 

Would have been cheaper for me to buy an expander.
