What is the Sensitivity alarm time? Would like to know at what ppm does the alarms start - one item I read was: 50ppm, alarms within 60-90 minutes. Thanks

UL standard: at 70 ppm, must alarm between 60 and 240 minutes. Below 70, may never alarm.

It is important to adjust the sensitivity on the unit. I would turn the adjustment until it alarms and then back off about half turn. That way it is pretty sensitive.

Put it in a large ziplock bag with small saucer. Light a small pc of paper, blow it out, put in bag on saucer. Close bag. Watch and wait. PPM should increase fast and alarm should go off, but it could take a while unless the ppms are 300+...

Ill have my husband take a look. As an RN I am surprised just how accurate this has turned out to be, not only with oxygenation levels but heart rate as well. My husband had an inconclusive sleecomp study and we decided to do this instead. Worked great thw alarm goes off when his oxygen levels drop, and has proven to us that he does have sleep apnea.

The minute the person gets up or attempts to turn over this alarm goes off. If you raise any part of your body that is resting on this it will go off. It is sensitive. I hope that answers your question.

Sean: greetings! Their are two probes (or prongs) at the tip of the sensor. When they are both touching water, the alarm sounds. The main part of the alarm unit sticks on the wall about 6 inches above the probes. The trick is to make certain that the sensor is also taped to the wall. If you just allow it to hang by the cord, it has a tendency to curl up a little which lifts the probes off of the ground. Good luck!

U have different settings. I think hi n low. Different settings is wider circumference before alarm goes off. Don't remember actual numbers

I can see your point about turning it off. I have a cheaper unit that I keep in my shop. Thinking about upgrading. I just turn the sensor toward the wall when I'm working out there so the alarm will not be sounding constantly all day when I'm out cleaning or working. Kind of like telling the guard "don't shoot! It's me! Just take the afternoon off"! I just have to turn it back around when I lock up. Form a habit like pulling your keys out of the door after you lock the lock. It's just habit.

I strongly believe it WILL sound give your proposed scenario as long as you have adjusted the sensitivity level correctly. A tip: if yhe alarm seems like it is sounding too quickly/falsely, it is likely that water is trapped along the thin metal ring inside the circumference of the blue round part. A quick shake or two will remove this water. Also, I used a silver marker to make a couple of reference marks so I could better adjust it. One on the outside if the light blue top and another corresponding one on the outside of the black adjustment ring. Then you can easily see where you are in terms of sensitivity.

It depends on how much light will wake you up. The alarm time should be the time you want to wake up (it chirps at the alarm time) and you set the light for intervals. I set it for 15 min, because I start waking up pretty fast with any light. If you're a heavy sleeper 30 min might be better.Good luck!

Hello, Yes, the alarm system once triggered, will sound for the determined amount of time you personally chose (00-30 Minutes). Then it will shut off, and reset. Meaning the alarm system is armed again, awaiting the next break-in attempt. Thanks. www.FortressSecurityStore.com

We had one sensor pad. Had false alarms now and then, but they decreased when we turned the sensitivity up. Also, make sure you have a piece of plywood that covers the entire area beneath the mattress so if the baby is in the crib corner, the breathing can be detected.

Is there a delay so that the alarm doesn't sound right away. Scenario: I'm leaving the house and want to turn on alarm; when I turn on the switch, does i make noise right away?

30 seconds to siren the alarm, that is too lonnnggggg. Specially you can hear the beep-beep sound from the MAIN control panel. that is not a good Idea, giving the burlar emough time to break the system before it siren.My solution is to buy another siren and disconnect the speaker from the main control panel. still 30 seconds, but burglar will not hear anything. the bad part is you don't hear anything either when you setting your alarm system.But I just both an on and off switch for the speaker. so I can hear when I do something with the system.I'm not sure if there is any other way to do easier than what I have. 30 seconds to siren the alarm, that is too lonnnggggg.

Mine lasted about 3 minutes. Alarm sounded and wouldn't shut off. I haven't tried returning it yet.

As far as I know, I believe it will run 10 min. continuously. I haven't really tried to. The pulse reading must get to 91 or 92 before the alarm stops. I hope this helps.

I had it set incorrectly the first night and the alarm sounded at 5:30am (sigh)... it's the third setting, not the forth. :-)
