Are there any End Of line Resistors for each zone?
If not the zone shunts JZ1 to JZ8 must be placed in the position nearer to the terminal blocks (see the installation Manual)
If there are EOL resistors then place the shunts awayf rom the terminal blocks
if the zone shunts are positioned correctly, assuming NO eOL resistors installed, ie shunt closer to the terminal blocks, then remove the zone terminal blocks from the system so the zones wires are not connected
Is there a zone trouble?
If no zone trouble that means that what you are connecting is causing the zone trouble
There should be No Voltage from the glass break and other sensors. They shouyld be giving only open/close contacts If the sensors are providing voltage then it will cause zone trouble
Check what is the output of the sensors

how to check if there is end of line resistor ?
what is terminal block?
when to use EOL resistor?
when not to use EOL resistor?
sir am not able to understand what is written in manual so please help me.write me in simpler explanation.

ake sure you have the corrrect maual . The Comfort 2 Installation Manual can be downloaded from http://www.cytech.biz/installation_manual.html
This explains the End of Line resistors (see page 25 thereabouts)
The purpose of End Of Line resistor is for the panel to detect if the wire has been cut.
End of Line Resistors are installed by the installer so you would know if they are installed or not. If they are not installed, then the zone shunts should be positioned on the header closer to the blue terminal block (or connector). Check that the shunts have not fallen off This is also shown in the Installation Manual
If the zone shunts are placed away from the terminal block and there is no End of Line Resistor, then you get Zone Trouble. I suspect that this is the problem
I assume there are no end of line resistors in the contacts
check which zone has zone trouble and check that the zone shunts is placed closer to the blue terminal block
see the photo attached showing End of Line Resistor connnection (whuch you probably do NOT have)

my sensor is NO NC contact there is not voltage , there is only potential free contact.

Please explain clearly what is the result so that we can assist you better
The reason for zone trouble is due to wrong placement of shunts of incorrect use of EOL resistors or wiring problems, due to wires shorted to something.
Try this test. For all the zones that have zone trouble, disconnect the blue terminal blocks from the Panel, check that the zone shunts are placed AWAY from the terminal blocks. Now there should not be any wires connected to the zone at all
Is there still zone trouble?
If NOT, then the zone trouble is caused by the wiring or the sensors. Either the wires are shorted somewhere or the sensors are not giving a dry contact
Please follow exactly and let us know what are the exact results

I think main problem is resistance because wire length is approximately 100 to 120 meters 10 to 15 sensor connected in series....there is a cat 6 wire ....have any dolution please tell me....I can't change sensor & I can't soldering each sensor .....because client is there staying..

I am sorry, you have not followed any of the instructions and given the results.
200 meters wiring should not be any problem
Please read the previous post and do the test requested

but continuity is ok.....I was short all zone and test system is ok what is the problem of zone troubling.

You mean you removed the zone wiring from the zones, and there is no zone trouble
That proves that the problem is in the wiring or the sensors.
There is a voltage on the wires
Next re-connect the wires, use a multimeter to measure the voltage from Zone to Common (center pin on the terminal block)
The zone shunt should be closer to the terminal block
measure the voltage with the sensor closed. It should be 0 volts
measure the voltage with the sensor open (ie door open). It should be around 1.3 volts
These are the voltage when there is no other voltage sources on the wiires
Let me know what is the voltage you measure on the affected zones

I understand from the distributor that the problem was with wiring of the multiple zones and it has been fixed
Wiring is the most important issue which causes the most problems in a system
