SAFE ALERTS

PRODUCT HIGHLIGHTS

  • Quick reports to your hub for low-voltage trigger signals from your interconnected hard wired smoke and CO detectors by all major brands like First Alert, Kidde, and BRK (do NOT use with battery powered detectors)
  • Recognizes and reports both smoke and CO signals from interconnected hard wired analog detectors individually
  •  NOTE:  This is NOT a security alarm component and the device is NOT part of a life-safety system. Check local regulations before installing.
  • Optional 120 V relay to control lighting or a security siren
  • 800 series Z-Wave chip: faster communication and more reliable network
  • Long Range: if your hub implements Z-Wave Long Range, you'll benefit from the latest direct device-to-hub communication which extends the range like never before and eliminates network lags
  • Built-in signal repeater: keep your mesh network stable and your system fast (not applicable to Long Range installations)
  • SmartStart and S2 authenticated security for a truly protected smart home
  • Installs in any interconnected detector box; the last box is recommended as it has fewer wires (check your wiring first and always follow the diagrams in the manual).
  • Pigtail wires included for quicker set-up
  • 5-year extended warranty when registered and tech support forever

    NOTE: Z-Wave gateway controller required - sold separately.

        NOTE: If you don't see your Z-Wave controller on the list above, please ask the manufacturer of your Z-Wave hub about support for the ZEN55 before you purchase this product.

        INSTALLATION

        Check your wiring first to confirm that you have all the following wires present in your electrical box: power, neutral, and the connection to the detector.

        If you are not comfortable identifying the wiring and following the instructions, please hire a licensed electrician.

        Here is an example diagram showing how to wire the ZEN55 to a smoke detector:

        INSTALLATION TIPS

        • Use with any standard interconnect smoke and/or CO alarms.
        • Always turn off the power at the breaker before handling the wiring, this is a 120 V high-voltage installation.
        • The last detector in series will be the one that only has 3 wires coming into the box (vs 5 or more in other boxes). This is where you'll have the most space to install your smart device at. (NOTE: it can be installed in any box in the series; the last is recommended only because of space.)
        • When adding the ZEN55 relay to your hub, you may need to scan the QR code or enter the PIN code located on the back of the relay (if your system supports SmartStart). Read more about adding the device to your hub here.
        • Test the detector's alarm (follow the instructions for your unit) to see if the status of the device changes in your hub's interface once the alarm goes off. Remember to warn your family members or roommates when testing this!
        • Always turn the power off when securing the module and the detector back in the electrical box.
        • You'll need to create an automation in your hub for a notification to be sent to your phone or email once the status on the ZEN55 changes so you can immediately know if the alarm is triggered.

        Used with a First Alert Smoke & CO detector.

        Easy to wire and setup into HA Z-wave JS.

        Works great

        This sensor was added instead of getting all smart detectors in my wired setup.. One goes off, they all go off and now i get an alert if it happens I'm not home. Test it occasionally and still working well.

        This thing is briliant

        I really bought it so i could tell if the smoke detector is going off. I didn't even realize at the time it could tell the difference between smoke and a CO trigger with two separate reporting sensors.

        I'm not sure why anyone would go with a questionable proprietary detector when you can get one of these and a more affordable smoke detector from an established brand.

        Worked as advertised with a First Alert smoke/CO detector. But a bit hard to pair because of its small, recessed button. You have to press it 3 times — quickly! Very simple integration with Home Assistant.

        Works great

        Pretty easy to wire into existing hard wired smoke detectors with interconnect. It really only works as a contact sensor, so not able to trigger an automation that sets off the smoke detectors as a siren as I hoped I could. But in my opinion, the best way to have smart smoke/co detectors in your home is to have "dumb" hard wired, and physically interconnected wiring with a smart relay like this. It will also detect smoke and C/O independently.
