Question: How loud is this unit? I purchased a plug in model and at the highest setting I could not hear it above the noise from the television.
Document: Lamson RC3500D device worked as promised. Installation instructions were good and installation took about 10 minutes. However, when at its highest volume setting, this bell is not very loud. It can be definitely heard at up to 30-40 ft away but could be louder. All in all, it was an easy fix to extend my existing wired bell to outside of the house.
The install was easy and the option for different chimes is nice. There are 2 drawbacks though to the unit. First, as other reviewers have stated, the loudest setting is not very loud. We have ours mounted on a wall very close to the pool and if there is any splashing or commotion in the pool it is very difficult to hear. Second is that the unit that connects to the in-house chime is large and there is not a good place to put it.
I'm very satisifed with my purchased. I really like that it is hard wired and not simply a "listen" for the doorbell to ring type model. Having it hardwired in prevents false alarms from thing like barking dogs, loud noises, etc. Very happy, great product. I also like that it is weather resistent and can go outside with me on the patio when need be. It operated on 4 "C" batteries.
The send unit was easy to wire in. It tapes to outside of existing bell housing case. Great variety of ring tones. The receiver has 3 settings. The high setting is very loud. The receiver requires 3-C batteries.
I was getting tired of not hearing the doorbell when I was out in the backyard with my daughter so I purchased this and asked my husband to install it. It took him 15 minutes and after a year of it being up under our patio it's still working flawlessly. I don't know why I didn't get one sooner,It's loud when you're right next to it but I really like the fact that my packages won't be sitting on my porch for extended periods anymore because I didn't hear the doorbell.Great buy!
It does the job well, I can hear the doorbell on the second floor now. Some reviewers complain about the sound volume but it's plenty loud for me, I set it on the Medium setting. Installation was easy. The only minor negative is that the transmitter doesn't fit inside the doorbell cover.
This unit was required to be able to hear the front door chime in the basement. It was easy to hook up except for the location of the chime. The sound output could be louder to cover a larger area.
In fact I could probably turn it down (it's on the loudest setting). This has solved my problem and I no longer miss deliveries.
Purchased the Lamson extend-a-bell based on reading others recommendations. I'm not a handyman, and usually break things when trying. However, installing this extend-a-bell was easy as pie. All I had to do was hook one wire to "front" and one on "Transformer", both inside my existing doorbell. Two wire hookup and bam, it worked. I also purchased the Thomas & Betts #RC3733D PlugIn Add ChimReceiver and it worked flawlessly with this unit.
Installs very easy if you can attach two wires to your present setup. Three settings for volume. middle setting is quite loud. I decided to not mount it. I prefer to be able to carry outside in warm weather. Exactly what I wanted.
Answer: yes
