Does everyone who uses an FMC ZyzaTech/Osmonics/MarCor V-Series type RO and Remote low level alarm made in the last 5 years realize the low level tank alarm will not sound if the power is off to the RO? What's with that?

Do you mean that the on/off toggle switch on the front of the RO or NO power at all to the ro?
I know that i have had a call at 430am about the low level alarm going off and what happen was the person opening flipped the flush on and the on/off toggle switch off. it still worked for me. my ro is about 6 years old now.

If there is an interruption of power, the RO has to be restarted using the on/off s/w.During this time of no power to the RO the low level alarm out at the nurses station will not sound a low level alarm when the supply tank gets low.

I had the same problem, with further investigation found that the alarm didn't function at all. Replaced the annuciator. (sound emmulator)

Does the alarm get its power from the RO unit?

Power comes from the RO. No power No low level audible ( you will get a light only) These are Zyza RO System installs within the last 5 years that do not have the stand alone monitors)
Model # SRFMNT Type 4 If you have one of these Shut off your RO and see what happens.

You will not have a low level light either.
Sorry my mistake.

I think the reason there is no alarm when the ro is turned off is because some clinics drain their storage tanks at night (3 day clinics)-nothing like alarms in an empty building

One of my clinics is a 3 day clinic and we don't drain the storage tank. We actually even have to leave the pumps running 24/7 because of bacteria problems.

Rookie, you are doing things the right way, I work with people that "think outside the box"

Did you know to that if the 2008K machine is not turned on, it won't give you an alarm either. I think it is a conspiracy among the dialysis and power companies to make us keep things "ON" and use up as much power as possible.

By the way, if the RO is off, doesn't that mean that nobody is at the clinic to hear the low level alarm going off, even if it did work in your bizarro world way of thinking? People like you, that over think things should not be in the dialysis field. Maybe you should go into the Hydro Engineering Field and design an RO that will alert people at home when there is a low tank level, even in a power outage.

Here's a scenario for the Biomed dude. It's noon, my 500 gallon storage tank is full and my 23G is in auto mode. One minute later I have a short in the 23G mother board that trips the dedicated GFI. Now my RO as no power, my tanks level sensors won't alarm and the staff are running patients unaware that the holding tank is running empty. the staff finally realize they are out of water not because of the no water alarms, but because they had to go back and check what the burning smell is in the Ro room. Yep, it's the 1500.00 distribution pump running dry. So as you can see, overthinking things can be beneficial.

Actually the above story would be more realistic if it occurred on a holiday.

I still don't see it happening that way. I understand that if you loose power because of a fault like that but won't your machines start screaming "NO WATER" and then if the PCT's have half a brain, they will run, not walk back to the water room to see that the tank is dry, and then you start to return blood. If this is a common occurrence, maybe it is time to buy a new RO or install a secondary level sensor that is not controlled by the RO. I am sure you can use the lower sensor that is built into the tank, a few parts later, and you have a low level alarm that is not dependant on the RO. Hmmmm, what a novel idea.

We have had our Zyza V-Series fail due to a short power outage. When it came back on, the RO was not reset. We didn't have a low level alarm when the tank went dry, but our staff was smart enough to read "NO WATER" on all the machines and could deduct that possibly the storage tank was out of water. By the time they got into the back, the pumps didn't burn up, the place wasn't on fire and nobody died. I understand that some biomeds love to live in the "What If" world. What if a meteor fell from the sky, do you have reinforced roofs, what if a patient goes to leave and instead of putting his car in reverse, he puts it in drive and floors it right through your front window, do you have anything to prevent this? I can go on and on about the what if's in life. It is life, deal with it. Now get back to work because what if one of your machines has a hole in the bc membrane and fresh dialysate is being mixed with spent.

Hey guys, let me through this out for food for thought, I had one clinic that had a mercury switch that was on the holding tank, for low tank level, this thing was dependable as a watch, power would be off and then back on, tank switch would always give us an alarm to check the holding tank when levels were low, and we had another mercury switch that would cut power to the recirc pumps when water reached a dangerous low in the holding tank...Handy and no calibrations to do, other than at install...
