Aeotec Siren 6 vs Heiman Smart Siren HS2WD series

The Aeotec Siren 6 narrowly wins, thanks to a higher rated sound level and its 1000-lumen LED strobe light. The Heiman Smart Siren HS2WD series counters with a longer-rated built-in backup battery, but the two are otherwise closely matched.

Visual alerting and protocol. The Aeotec Siren 6 adds bright LED strobe lighting rated at 1000 lumens, which the Heiman Smart Siren HS2WD series does not offer, only a flashing red LED. The Aeotec Siren 6 is a Z-Wave device while the Heiman Smart Siren HS2WD series is Zigbee, so they need different hubs.

The Heiman Smart Siren HS2WD series is rated for about 12 hours on its built-in battery, longer than the Aeotec Siren 6's embedded backup battery, which is rated for up to 4 hours during a power outage. Both units are primarily designed to be wired.

Yes, both the Aeotec Siren 6 and the Heiman Smart Siren HS2WD series support Samsung SmartThings and Home Assistant, though each needs its own type of hub, Z-Wave for the Aeotec Siren 6 and Zigbee for the Heiman Smart Siren HS2WD series.

Choose the Aeotec Siren 6 if you want the louder rated alarm plus bright strobe lighting, and possibly a doorbell chime feature, on a Z-Wave setup with SmartThings or Home Assistant.

Choose the Heiman Smart Siren HS2WD series if you run a Zigbee hub and prioritize a longer-rated backup battery over strobe lighting, keeping in mind it has no established owner review track record yet.
