Anti Masking & End-of-line


Olly

Recommended Posts

Hi again,

Flushed with the success of my last post, here's question number 2...

Can anyone point me in the direction of a guide to anti-masking and End-Of-Line signalling? The terms appear a lot in product literature, but I can't find a resource that explains what they're all about... is it all about the resistance of the circuit indicating the detector/fault condition?

Many thanks,

Ol

DIY install, anti mask not required so no worries there.

There is some info on this site in another thread somewhere re: EOL, you just have to find it.

But again, not required if you are installing a system yourself so if you want to keep it simple and straightforward then just ignore AM and EOL.

Depending on what type of panel you are going to use you may well need to know about end of line wiring as some panels use resistor value to determine what state a particular circuit is in as for anti masking on a diy system not even worth worring about

Once again - thanks for the direction. (this is the most responsive, most helpful forum I've ever used!)

For info, I'm putting in a Texecom Premier 48 (Not that I have 48 zones! I needed a panel with Ethernet - and yes, I've got the IPCom module too) and Texecom Prestige MR PIRs.

The panel installation instructions describe EOL Normal and then EOL w/ AM connections, both of which appear to require a load of resistors and a fair bit of head scratching. It then goes onto Double Pole connections which appear to be much simpler (i.e. two circuits, one for alarm and one for tamper) - that's the way I'll go, unless you guys say otherwise!

Ta,

Ol

Double pole is best for DIYers.

The opinions I express are mine and are usually correct!

(Except when I'm wrong)(which I'm not)

Hello,

I want to install a texecom r8+, and I need to plug multiple PIR in series on a single zone.

I was interested to plug them with an EOL on the last pir: "American operation" with a single resistor of 10k in series (because "European" and "HighSecurity" need a single pir on a zone). But in this case (in fact, in all the three cases of EOL operation), the r8+ manual says that we don't have to plug the global tamper. It's interresting because we need only two pairs instead of three pairs for cabling, so less contact, less work... But in this case, I think the pir is not monitored if someone open it ? I don't understand why this kind of EOL is more secure than the double pole ?

(sorry for my poor english speaking)

sorry surports only one eol device per zone,
