For the smoke alarm side of the device - does it have dual smoke sensing? i.e.electrochemical and photoelectric technologies?

Smoke Alarm side is photoelectric only. To have the ionization detection, you must purchase an additional alarm. Keep in mind that there is a maximum number of alarms that can be connected together.

Hello, Bottom view smoke detector = straight down if from ceiling or straight out if from wall mount. Bottom view smoke detector if mount on ceiling you will see top of someone head, and perfect for cashier machine. Side view smoke detector is only for ceiling mount, and perfect for slight angle downward to see up to 75% portion of a room. Most popular is side-view smoke detector , but if you are aiming for something completely straight down view to see like cashier machine, then bottom-view is perfect for you. Note: This item maximum per hour last is 8hrs. (Rechargeable) Thank You.

The low battery alert on these smoke detectors is a small beep. However, when they sound off due to a fire or test of the alarm, they are very loud and repeating. Of course, that's a good thing as you want both you and your dog to be running from the alarm and out of the house. They are truly the best smoke detectors we've ever owned.

It is like a smoke alarm. I just replaced an existing one, so did not have to decide on location.

Let me start by commenting on the date on the device, since it has come up in other posts. I ordered my smoke alarms in May and the device was stamped end of March which seemed quite reasonable. Yep, replacement time is 10 years and if I do it exactly on the 10 year mark I'll be amazed with myself. As per your question Edwin I hooked up my alarms to the house power and they did the low battery beep until I pulled the plastic tab out of the side of the detector which made the battery connect inside the unit itself. I used the battery that came with the unit and didn't need to ever open the battery compartment. When I do replace the battery if it continues to beep I would check the battery connection and also make sure that my batteries were not dead. I expect to replace all the smoke alarm batteries the first of the year, which is what I used to do, and didn't bother this year because I knew I had to replace the detectors. Best of luck with your smoke detector.

Yes you can. Activate the alarm by pulling out the battery protector tab and plug the smoke detector into the existing home wiring. When completed, test the system by pressing and holding the test button for a few seconds and make sure all alarms sound at once.

No it does not. I returned this unit after one smoke. The Bluetooth capabilities are useless. If you are using this as just a thermometer you are good to go. If you need remote functionality, RUN!!!

I would rather use a lithium 9v for smoke detectors. Check the manufacturers recommendations.

I have electric wires already installed to make all alarms be on same circuit.(AND uses battery back up) Is there a combination smoke /CO detecting alarm made for this?

The unit has a battery in case you lose electric power, but they are also connected to your house's electric wiring so the battery doesn't need to be replaced so often. In addition, when one smoke alarm goes off, all the smoke alarms in the house go off. This is important as I have a smoke alarm in the basement that I might not hear from some of the bedrooms if they all didn't go off together.

there is a rotate off base that mounts on an electrical box. The base is very similar to other smoke alarms and there is an electrical connector with about six inch pigtails.

No, it will only silence that one alarm. If the smoke has not cleared in 4 minutes, it will sound again. It will also silence the low battery beep for 24 hours. (If your batteries happen to be low).Why are you finding alarms with missing batteries?

I have five smoke detectors, they are all photoelectric. The product does work. On the bottom of the can there is a note: Excessive spraying may effect the detector's sensitivity.Another note on the can, for use with smoke alarms listed to UL standards 217 and 268.I read the previous answer, my previous smoke detectors stated they should be replaced every 10 years which I did. My current smoke detectors have the same note, they are all connected to my alarm system.

They are hybrid probes, as mentioned in the description. You can use one or both to monitor the smoker chamber temp.

you can replace it with any smoke alarm that supports your connection, these are great smoke alarms and I stayed with the 1276 units, they are easier to change the batteries in,and they have a great track record.. but its your call any smoke alarm is better than none..hope this helps.

No, but they do offer smoke detectors that you can buy separately that will work with the system.
