Honeywell WAVE-2 Two Tone Siren

Works good

Works as expected.

These are super loud. More than I expected. I got a couple for my smart home system and hooked them up using a standard 12v power supply (like tons of modern electronics use; routers, tv boxes, etc.) and a smart plug. Just set the smart plug as one of the devices that is turned on if the alarm is triggered and it will turn on the audible alarm. This also gives you the ability to manually enable and disable the alarm as well.

Was perfect for use with our driveway alert. Perhaps a bit loud for the inside of a large, mostly empty, concrete block building.

I wired this siren to a Qolsys IQPanel 2 and this power adapter: https://www.amazon.com/gp/product/B07D8GXSRV/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1 It works great, loud enough to be heard throughout the house. I attached the Qolsys panel wiring diagram for reference.

This thing will wake everyone in the house! Great sound quality! Love that it has dual power input. I have the Warble plugged into a Smart Plug for my Security System and the Constant tone plugged into my Leak Detectors. When this thing goes off I jump clean out of my skin! Great intruder deterrent.

Did not work with my Ademco system. Observed polarity but no sound. Checked with another old sounder, so I know my system works. ??

I installed this in a few mins. Plugged into my SAM DIY but only works with one of the tones. When I arm or disarm with my remote it chirps like a car alarm but a really loud version

You have to install your own wire but overall the sound is loud and I used an old 12V adapter so that I could plug it in 110V outlet. It works perfectly well and sounds can be heard outside the house.

Item works as designed and is SUPER loud. I have a Vista 20p with 3 of these hooked up, and not sure anyone could live through that sound for a long period of time!
