Homemade Leak Sensor - Better and Cheaper

If you look closely you'll notice another set of holes just above my screws where the wires are attached . This was one of my first units I made. There are some solder points on the circuit board and on one side it was making contact with my screw head so I had to move them down a bit. It was very frustrating trying to figure out why my sensor wasn't working reliably until I finally realized that was the case.

This unit was made to be used with an external contact. In the first pic showing the unit open but still assembled it's showing the wires coming up and connected to the elevator screws made specifically for that purpose. No modifications necessary.

Shannong, can I pick your brain about this again?

 

I got a few 5816 sensors, connected wire the two blue terminals (the block inside), and set the sensor to the Elk in ElkRP to be:

 

Definition: Water Sensor (Also have tried burglar instant to get an instant alarm going)

Type: 0 - EOL Hardwire/Wireless

Supervision: 1 - Normal Supervision

Loop: 1

 

If I put the magnet near it and take it away, I get an immediate alarm. If I place the two wires into water...nothing.

 

I've tried different variations of Supervision and Loop and still get nothing with water on the wires.

 

Am I missing something?

 

Please help! Thanks.

And...now it seems after playing with this stuff the TELCO SEIZED and DIALER ACTIVE LED's are constantly lit on my M1.

 

I've disabled the sensor I've been testing, and shut down/restarted the M1...but still the 2 LEDS are constant on.

 

Anyone have any ideas about that?

 

P.S...I'm not currently connected to the central station monitoring.

Hmmm...ok. So, with that said, how do I connect the unit together? I've tried having the magnet attached to the board (as in reading a closed door) and water on the wires, no luck. Works like normal, magnet on is good, magnet off sounds an immediate alarm.

 

How do I connect the "1st and 2nd loops"?

 

Any help is much appreciated!

I've got the sensor setup with the wires, but when there's water on the screws, I get ready to arm. When no water is present, there's no "connection" so my system is Not Ready to Arm.

 

(I've got this setup as Burglar 1/2 just for easy of seeing how/when it connects, does not connect).

 

Essentially, it seems like it's working in reverse. I've got to be setting the setting up incorrectly. Anyone know the proper way to setup the settings?!

Working with the setting on water, and loop 1, I'm getting a zone trouble - water alarm when wet, and when I pull the sensor out of the water, the alarm goes off. Totally lost here and trying every combination possible!

The sensors must be added to the Elk as Loop 1. Loop 2 is for the magnetic closure contact. Of course, any time the cover is off of the sensor it will show "Violated" as the housing as a tamper sensor.

 

You need to add them with the "Option 2" checked under Wireless Setup. By default, the Loop 1 wired contact is Normally Closed. Setting the Option 2 tells it that it should be Normally Open and contact with water will close the loop thus setting off the alarm.

 

I added my sensors as "Definition 16- No Alarm" instead or burglar. I don't want a water sensor setting of the sirens and house alarm. My Elk also directly controls my water valve using an output on the system. So I created rules that say "When Zone 110 is Violated, Then Turn Output 192 On". Output 192 closes my water valve. In ISY, I have rules that send me alerts and other actions (such as turning off the On/Off module on my washing machine) when it sees Output 192 on.

Thanks shannong. Exactly what I needed. I'll play around with it tonight and update. Hopefully all works as easy as it seems it should.

 

Thanks again.

@shannong

Are the 5816 transmitters sending directly to your security system, or to a receiver that interfaces with your security system? Can the shutoff valve receive the water event directly, or is there a receiver that can pickup the water event, then trigger the valve to the closed position?  (i.e. for those of us who don't have an M1)

 

I like the Elk Shutoff valve and the receiver solution you described, but I want a user friendly interface that can send email notifications in addition to triggering the valve (like the Insteon controller with smartphone UIs).

 

Also, I have a DMP security system.  Do you know if I can interface the 5816's to it?

 

Thank you,

John

DMP does have an HoneywellAdemco receiver interface module that works with a handful of the Honeywell transmitters of which the 5816 is one. 

 

Like most security systems, the Elk needs a wireless receiver attached to use wireless devices including the transmitters made by Elk. My Elk has a Honeywell receiver module attached. The 5816s communicate directly to the Elk with that.

 

My Elk can send emails, texts, etc and can even integrate with some home automation products but I don't use it for that. All alerts, messaging, home automation tasks are done on my ISY using the Elk integration module available for purchase on your ISY. Then ISY can see that state of all zones and outputs on my Elk and even control them. I have some programs on my ISY that will trigger the Elk to close the valve or even open it. For example, I don't let the Elk shutoff the valve when I leave if my dishwasher or washing machine is active. The valve is not shutoff until they finish. However, the Elk handles most situations to operate the valve based on Alarm state and if one of the 5816s is triggered since it's more reliable than Insteon and has a long batter backup.
