Siren 6. Also Doorbell 6.
Siren 6 really is Z-Wave’s most connected alert system. Easy to set up as a siren, it’s just as easy to convert it to a doorbell. Paired with an optional accessory, Button, Siren 6 will offer the same functionality as Aeotec’s Z-Wave doorbell, Doorbell 6.
Aeotec Button is sold separately.
