Feedback regarding Ecolink Fire Alarm Audio Detector (www.zwaveproducts.com)

Does anyone have feedback on how well these work?

I have fire alarms on different floors of the house and I'm wondering if this device will be able to listen for the alarm from another floor. The alarm is still quite loud throughout the house but the instructions say it needs to be right next to an existing alarm.

I'd rather not have to buy a bunch of these if possible.

I have one. It does work, and can distinguish between smoke and CO alarms. You only need one if you have interconnected hardwire alarms; you won’t be able to tell which specific floor it starts from.

A newer solution would be this: https://www.getzooz.com/zooz-zen55-dc-signal-sensor/

No batteries needed, same function, and while I haven’t had any reliability issues with the sound detector I figure the hardwire one is likely more reliable. I just installed one a couple weeks ago, very simple, now I have two detectors.

I used the ecolink device for some years until I discovered the Zen55, which I implemented a few weeks ago. The ecolink stopped detecting CO after I changed my interconnected alarm system to a new Kidde model as the old one started to give occasional false alarms. The ecolink was also unable to clear the CO Alarm once triggered with the old Kidde model I was using, it required removing and reading the device from the zwave network.

Zen55 worked perfectly, able to differentiate CO and smoke signals and auto-clears when the alarm condition stops. It requires no batteries.
