Installation instructions for the Ecolink ECI-SZW7-ECO Z-Wave Plus Chime+Siren, a line-powered indoor siren/chime with 14 built-in sounds and 24-hour battery backup.
Installation instructions for the Ecolink ECI-SZW7-ECO Z-Wave Plus Chime+Siren — a line-powered, Z-Wave Plus enabled indoor siren and chime with 14 built-in sounds, 24-hour battery backup, and full Z-Wave Plus S2 security.
Locate the device's DSK QR code on the back of the unit, on the packaging, or on the included leaflet. Plug the device into a wall receptacle — it automatically enters SmartStart inclusion mode. Scan the QR code with a Z-Wave controller that supports SmartStart to add it (refer to your controller's manual for activating SmartStart).
With the device powered, press the smaller Add/Test button. The device enters classic inclusion mode (both classic inclusion with Node Information Frame, and Network Wide Inclusion). During inclusion the Green LED blinks 3 times every 3 seconds. If inclusion times out, the LED blinks Green and Red alternately.
| Event | Blink Pattern |
|---|---|
| SmartStart Started | Green LED 3 times |
| Classic Inclusion Started | Green LED 3 times, every 3 seconds |
| Classic Inclusion Timed Out | Green and Red several times |
| Inclusion Successful (S2 Authenticated) | Green LED solid |
| Inclusion Not Successful | Red LED solid |
Put your controller in Remove/Exclusion mode, then press the smaller Add/Test button following the same procedure used to add it. On successful removal the red LED comes on solid for 1 second. Any Z-Wave controller — regardless of manufacturer — can remove a Z-Wave device from a network.
Remove the device from the power outlet. While holding the Add/Test button, re-insert it into the outlet and continue holding for 10 seconds. The Green LED flashes during that time; after 10 seconds the red LED comes on solid for 1 second, confirming the reset — the device is now ready to be re-added to a network.
The device uses industry-standard elliptic key cryptography (S2) to encrypt sensitive communications. The DSK code printed on the device (and in QR form) is used to authenticate encrypted command classes. A Security Enabled Z-Wave Controller is required to fully utilize the product.
14 built-in sounds are available, playable via the Sound Switch, Basic, or Indicator command classes. Volume is adjustable via the side buttons, the Configuration command class, or the Sound Switch command class. A Basic Set of 0xFF triggers whichever sound is configured as the primary siren/chime.
