Smoke detector false alarm and additional triggers?

This morning we had two false alarms on our SimpliSafe SS3 system, one from a smoke detector, and the other from the motion sensor in the room where the smoke detector went off.

What was odd is that the system was in Off mode when I got the call from monitoring about the motion sensor alarm.

I suspect the motion sensor trigger was from when I went into the office with the smoke detector while the alarm was going off to see what was going on.  Is that possible?  I now suspect it too may be defective.

The system is relatively new, just a few months. This is the first time we've had any issues or false alarms with the system.

Monitoring has put our system into Test mode until this sorted out.

I am unclear if I need a warranty replacement smoke detector and motion sensor or what.    

At this point, I'm very wary of the whole system as I can't be having false smoke detector alarms happening, ever.

So far no other issues after cleaning the smoke detector and checking the battery and doing a test on it.

I'm still wondering about why we were getting motion sensor alarm triggers when the system wasn't even in a mode that would trigger if that sensor would go off.  

Could it be that once an alarm trigger happens from the smoke detector the system continues to consider other triggers an alarm condition until the system is disabled. When I look at the event log, it appears that the motion detector alarm trigger happened after I disabled the system at the keypad, which is very odd. Maybe just a delay in the data getting back to SimpliSafe?

Hi @stef.stclair,

Whenever any alarm event is triggered all of the sensors with your system will arm themselves regardless of which mode the SimpliSafe system was in previously (Off/Home/Away). This explains why after the Smoke Detector triggered an alarm, your system started triggering a few alarm events from your motion detector before the system was disarmed.

With respect to your question about being called even after having disarmed the system, not all alarm events follow that same procedure. As you know, most alarm events require the siren to have gone off for at least 30 seconds before the monitoring center will give you a call. Other alarm events that affect the potential safety of our customers (Smoke, Carbon Monoxide, Panic, Duress) do not have the 30 second hold time and will always result in call(s) from the monitoring center.

The exact thing happened to my system this morning.  Nobody up.  Fire alarm went off, then log shows that immediately the master bedroom motion detector detected motion.  System was in Home mode, motion detectors are supposed to be off.  I know that one was because I'm an elderly guy and had gotten up a couple of times during the night to perform a task in the 'old guys fluid exchange program'.  The two support people I spoke with had me reset the detectors and base station (dislike having to have a small screwdriver to reset the base.)  No fault was found.  Not sure I trust the system now.

My bet on a motion detector going off when an alarm does is that it is either on purpose but might be as seisiuneer said and I could see it might be helpful for the monitoring center to see motion alarm detects if there actually was a fire so they could tell the fire department there is someone in the house.  However, it could be a software bug has been pushed out.  Spent my life in software development and testing and at this point pretty sure it could be either.

Called tech support 7 times this afternoon, and kept getting hung up on while on hold, once while talking to an agent.  It would have been a nice touch if they had called me back as they had my phone info, but it didn't happen.  Figured out that when on hold, it rings like it is being transferred, then dead silence.  Wait, don't hang up!!! After a minute or so of dead silence, an agent picks up.  Likely they are working from home due to COVID and it takes that long for the system to connect you.  Kudos to the monitoring folks as they called within 30 seconds of the alarm and also later while I was testing.  Maybe they have to be at a monitoring center rather than working at home.

Not a happy camper.  My sleep cycle was only half over and hard to settle down after this, so I will be tired the rest of the day for no other reason.  Hope it does not happen again.

Actually glad to hear someone else saw the same behavior with the motion detectors after a false smoke detector alarm.

I cleaned the smoke detector (and the other smoke detectors in the house) and checked the battery.

No other false alarms this weekend so hopefully this was just a one time event due to a dusty smoke detector sensor.

Interesting. Same thing happened to me this weekend. Burned some toast and set off the smoke sensor. On my way over to reset it, I tripped two of my motion sensors, even though the alarm was off. Monitoring station called and said there was motion and fire alerts. App indicated the same thing. Seems like there's a bug in the software that arms everything when the fire alarm is going off?? I should have tried opening the front door and seeing if it records that entry sensor as well. Any input from SimpliSafe??

We should dig into your Event Logs to investigate. Sometimes the logs on our end will have more info that can help. If you haven't already, give us a call at 800-548-9508.

I had this happen to me back in January and talked to a support specialist as the simplisafe behavior didn't make sense, and I still don't agree with their answer. But essentially once the smoke alarm goes off, it puts the system in alarm mode regardless of what state it was in before the smoke alarm went off, which is why the motion sensors and entry sensors activate. You have to turn the alarm off at the keypad even if you tell monitoring it's a false alarm.

I complained about this behavior because if the smoke alarm is going off because of some cooking smoke and a window is opened, I shouldn't have to respond to monitoring with my pin in terms of the security alarm if the system was in the off state before the smoke alarm triggered. Alas, I never heard back.

Did you honestly think you'd hear back?

Hi @cjroth

That is the normal functionality for all alarm events for the SimpliSafe system. It is useful in that it gives some additional insight into what may be happening as you can view the sequence of events from your timeline. That being said, I have gone ahead and submitted your feedback that you'd prefer that not to be the case for Smoke Detector alarms.

We had a similar situation happen this week.

On Friday night we were cooking some pizza and caused some smoke, which triggered the smoke alarm. Our alarm was in Off mode, as we typically don't have it on when visitors are over.  This is the first time it has gone off, and we put in the code and thought all was well, getting back to our pizza.  I typically don't carry my phone on me while home and unfortunately my wife and I missed about 5 calls each from SimpliSafe. This was surprising because I wasn't aware they would call if the code had been entered just as they don't when we accidentally open a door while the alarm is on then put in the passcode. Well, a few minutes later the fire department showed up. I told them all is well and they were kind and left.

Afterwards, I received another phone call from SimpliSafe saying our motion detector was tripped many times, along with our door sensors. This was confusing to me since at no point had we turned on the alarm. I told them all was well, gave them my password and went about my evening. There was also a message on our keypad saying it was disconnected, but it then quickly returned to normal. 40 minutes later I had a police officer knocking on my door saying they were responding to an alarm. After a pleasant talk with the officer that nothing was wrong, I called SimpliSafe to see what was going on and why police had been dispatched after I had spoken to the monitoring company and told them all was well.

After a few different calls and getting the call dropped on me after 15 minutes of holding, I got a call back. They said there was "a lot of activity going on" and that next time we have company over we should call them and put the system in test mode. This was confusing, since I had never even turned the alarm system on, it was off the entire time. Reading above I now see that a smoke alarm triggers the entire system to go on. While I understand the reasoning behind this, I would really prefer this not to be the case, since it caused quite a bit of confusion. Would much rather they just call us or the appropriate resources if we don't put in the code on the keypad.

Since then, we have had multiple false alarms with the same smoke detector. 3 so far since the initial incident. This is concerning since it did it's job picking up the smoke the first time, but now it is going off randomly including once at 3am yesterday morning. We talked to the monitoring company and they put it in test mode, but I'm not sure what that will do. I'm worried because my wife and I both work, and would by mortified if the fire department was dispatched for a false alarm. I looked up the issue on the website and have cleaned the smoke alarm, hopefully that does the trick.

This happened to me today.  Cooking dinner, alarm off, smoke, smoke alarm, motion detected.   Seems to me that Simplisafe is missing the opportunity to advertise this as a feature.  Had I known that motion sensors would become active upon a smoke alarm triggering, I would have put motion sensors in my kids bedrooms.  God forbid we had a fire on the second floor, I would love for the fire department to know where my family was.  

Of course, I think this functionality should be documented and optional.

I also think the central station needs to know why the are getting the extra alarm signals.  Consider it non visual confirmation.

Same thing happened to me just now.  My garage smoke detector went off and then my living room motion sensor went off because of my cat.  So let's assume they do turn on all motion sensors once a smoke alarm goes off so they can know where people are during a fire.  That's fine, but doesn't explain my garage smoke detector going off at midnight when nothing was going on in there.  

I have to say I'm not impressed and it looks like a common problem.  Blasted my ears out walking next to all these damn alarms and didn't think to silence things because the system wasn't even armed.  I do know smoke detectors are always armed though, which is good in my opinion.  But false alarms are unacceptable.

Same exact thing happened to my wife and I last night at 1:20am !!! Fire alarm false alarm in my workshop.  This system is only a couple of months old.  Getting woken up in the middle of the night to a screaming alarm is unnerving.  After panicking from the noise, the monitoring service calls as they should inquiring about the event.  Half awake still, it took me a few seconds to even be able to comprehend their questions over the screaming alarm system and state of panic we were in.  Upon checking my workshop, there was no smoke, fire or anything.  Total false alarm.  no way the fire alarm was dirty inside causing the false alarm since it's practically brand new.  This is the third false alarm we have had since installing this system.  Twice before it was false alarms being set off by motion sensors in my workshop.  My wife and I were on vacation and out of town when it happened the first two times, so you can imagine the panic we suffered thinking our home was being broken into.  The false alarms are not acceptable and I am really starting to question my security system choice here.  Oh and as others mentioned, although last night our system was in "Home" mode, when the fire alarm went off, it also tripped some motion sensors which i too thought was strange.  If we have one more false alarm, I am ripping this stuff out and am going to demand a refund for it's return and go with some other system.

Sorry to hear about this! A workshop isn't really the best place for one of our Smoke Detectors. As you note, it triggers whenever particles can get into the detection chamber. It wouldn't really take long for dust to get in there.

We would suggest moving the Smoke Detector to maybe just past the door into the rest of your house. That way, you'll still get an alarm if there's a fire in the shop, but at least there's the door to keep the dust away.

Can i disconnect a smoke alarm from Simplisafe but have it still perform as a standalone alarm with local warning?

@proche195​ yes, the SimpliSafe Smoke Detector is essentially the same as any other smoke detector on the market, except that it can connect to the main security system for dispatch. If you remove it from the system, it will still act like a normal smoke detector.

Hi, the organization I belong to has your system and one day the smoke detector went off on it's on. The environment is dusty and is used as a social club. That being said how often should the detectors be cleaned and what is the procedure to do that?

Thanks!
