Hi All,
Since some time ago my WC flood detector automatically start giving an alarm that is activated. I reset the central after that keep ok but only for a while. After a time it goes to the alarm again.
I have 3 Flood detectors WC suite , WC Social , WC Kitchen.
At first it was the WC Suite that start's the alarm.... and after a few times i turned off... the issue don't happened anymore... good.
Some days passed with the detector off and last week it started the WC Social giving the alarm. I do a reset on the central and after some hours or days (dont' have a fixed time to do the alarm) it start giving the alarm. Today the same happened one hour ago...
I keep the I/0 monitor running and copied the report. If it helps on the tracking of the issue here it it . Please help me for i don't have to take it of all the flood detectors and to not die drown

My central was updated some days ago but this error was already happening before.

The I/O monitor shows that Input 5 is activated causing alarm type 28
I dont know if that is the floood alarm
Inputs being activated can only be because of the detector. Comfort cannot cause an input to be activated so I suggest you check the detector. Perhaps it is too sensitive
Are you using double end of line resistors or no resistors? You must check that the zne shunts are correctly set in each case

Yes,
the input5 is the I_WCSocial.... that's the flood detector...
How can i check if the zone shunt's are ok? if i post a pic of the detector can you help me?
It's because i already talked with Domopor... but they said that will the the issue and no answer till now.
when i arrive home i'll post a pic of the detector... the detector's are brand new.. they replaced it and add a new "mini-board" they were ok for 2 / 3 months after they changed them. but with no changes they start with that issue.
thanks

The Installation Manual download from http://www.cytech.biz/installation_manual.html shows how End of Line resistors are connected
and the position of the shunts
I dont think a photo of the flood detector will help
Zone shunts JZ5 should be inserted in position on 2 pin shunt away from the terminal block is EOL resistors are used and closer to the terminal block if EOL resistors are not used

What is a EOL Resistor? sorry for this.. but i have to know it because if i am waiting for the vendor i get spider cobwebs

EOL is End Of Line Resistor
The installation manual explains what they are used for
But you need to know if they are installed?

EOLs are used at the 'detector end' of any detector - these will either be discrete resistors or be actually built into the detector itself.
They provide a method of detecting if the cabling to the detector has been tampered with (i.e the resistance changes). EOLs from recollection are either 4.7KOhms or 2.7KOhms.
The Comfort CPU needs to know if you are using EOLs or just setting up as Open or Closed circuit - this is done via the jumper next to the Input you are using (as Ident has mentioned)
The simplest way to check is to measure the resistance of the Flood detector (at the Comfort CPU end). You will need to remove the terminal block that the wires come in from first, from the CPU before doing this.
Bridge the flood detector with some wire and if you have EOLs these will be seen as a Resistance, if not you will just see a few Ohms based on the resistivity of the cable run to the detector.
Running the Input with the incorrect EOL setting may cause issues and potential triggers.
Hope this helps..

Hummm yes it helped a lot , is good information but i am not an expert yet on this  i'm from TI and trying to learn by me this system
but i have to check if it's correcly connected on the central.. i supposed that is it because it was from a day to another that this issue happens. it was working fine.
each detector have 2 jumpers... but they are not shunted...
the detector have 2 little metal "things" that are almost touching the ground , that is if it detects water on them it generate an alarm and cut the water.
is is possible for you if i take some photos of the detector you help me? i take one photo of the one that is from the Kitchen that until this moment is working. and another pic of other in the Bathroom.
When i arrive home i'll do that
thanks

No problem, I have seen these detectors before, however if you want to include a pic then it won;t hurt.
The basis to the test is not really what the detector looks like but more as to what is causing it to trigger the Comfort System.
The following is from the user manual on how to set the jumpers for EOL.
JZ1 - JZ8 3x8 way header - Insert shunt in the position nearest the terminals
for the corresponding Zone 1 to 8 if no EOL resistor is used for the zone. Insert
a shunt in the position away from the terminal block if Double EOL resistors
I suspect you will not require EOLs on the Flood Detector as it is more to alert of water ingress as opposed to a break in and doesn't therefore require the same level of protection on the cabling.
This however can be confirmed by testing the resistance of the cabling as I explained earlier.
If this is intermittent then maybe re-position the flood detector so it is no-where near any water - then see if it trips again?
Hope this helps...
