What is the dB rating for this alarm?
184547
Really loud! Not sure of the ratings, but it hurts my ears when used in a small room or within a close distance. Just remember to have it accessible if you are going to use it. It only takes a second for someone to come up on you. Don't put it in a bag or pocket and expect to grab it in the event you need to use it. The same with pepper spray.

Its listed as 130. It is pretty piercing and does it's job. I bought them for my girls when they go to the park and we tested it out and it was loud enough that the neighbors were coming outside to see what the commotion was about. The light is not really bright enough to really make a difference, but it is effective for what it is. I hope this helps.

some one told me that Mace is very loud. I tested it with sound SPL meter and it show 105 db

not sure on db rating but it's quiet for an impact. Composite body also so it helps w/ noise. Sounds about as quiet as the IR2135 which is known for being on the quieter side. I have both, i grab the CP first every time.

Yes.... The question you should be asking is what kind of alarm is installed already? and is the alarm compatible? This PA system is an "add on" to your alarm system.

Can't tell you dBA, but it's rated at 4 sones. That's not exactly quiet. I have one that I am replacing because it's too loud. It's fine for the half bath where a the sound can offer privacy. But in the master bath, it's just loud. Watts are unknown but it's not Energy Star rated.

The standard for sound alarms that remains consistent focuses on the sound level of the device when activated, which is listed at 85db at ten feet. Local statutes vary on whether or not any given device may be battery operated only, or must be hard-wired with a battery back up. That being said I cannot find any documentation regarding the noise level of this device, which means you will need to go with a product that clearly lists its sound output in DB, or clearly states that it is UL 2017 COMPLIANT.

Jesus, Hi. I would read the manual for the frequency range for the wireless reed transmitter and receiver. Off hand I do not remember. It is a great alarm system, I have it for 3 years now with no problems.

I'm measuring about 66dB peak when I measure the alarm from about a foot away with my SPL meter (in fast mode; in slow it measures about 62dB peak), but since the beep is mostly 4k and 2k Hertz (with some additional overtones at 6k and 8k) it is audible over a lot of other things even at that relatively low decibel level.The alarm beeps four times in fast succession, once per second, with the four beeps taking up about a half a second, and then silence until a new 4-beep succession starts. This goes on for one minute after the alarm starts.The vibrate function makes it vibrate instead of beeping; you can choose beeping or vibration but not both.

What?... huh??? Can't hear anything but this alarm!Quite loud! Let's put it this way, for a little unit... you will want to hold your ears if it goes off!I think it's about 120 db and Pain begins at 125 db... close enough...

I read somewhere that it was 120-150. I don't think Bose really focused on the "power rating" they were more about the quality of sound!

Honestly I haven't hooked my up yet but I also but I also bought the smaller indoor version. Any time you power it with 12 volts DC it screams either continuously or as a wave. The 748 has the same features but it is louder yet. Just make sure you connected to a 12 volt alarm output.

I also do not know what the dbm ratings are, You will have to check the site for that. I have had the antenna for quite a while now. Works amazingly well. holds up strong in the storms as well. It is mounted about 40 to 50 feet above the found. Its a very strong antenna as it picks up weaker broadcast signals.

Katrin, the unit is very silent. It doesn't have the noisey fan like a wet spong humidifier. I don't have a DB rating but it is easy to sleep with.

i think it is a standard decible level for alarms - not particularly quiet. Sounds just like the travel alarm I've got.

Don't know how to measure Dbs. If it helps, I set the alarm in my kitchen and walked to the farthest bedroom in my one-level home (counted 27 paces) and I had no problem hearing the alarm from inside the bedroom.

Tested in my garage using dB meter set on "C" scale (32-10,000Hz) - 87dB at 1 foot away and 78dB at 4 feet away - this is very quiet.

I do not know the answer, I actually need to return this because it will NOT work with my car alarm system. I purchased the wrong model.
