When the LED of the Everspring Z-Wave Indoor Siren is not displaying and siren is not working as well, then the reason might be:
The siren’s battery has drained.
Maybe the battery polarity has reversed.
Maybe the siren is out of order.
You can resolve this issue by:
Changing the old battery with a new one.
Make sure that the polarity of the battery is correct.
- In case the siren is out of order do not open the siren. Please send it to the retailer.
