Engineered for seamless integration, this mains-powered siren ensures that any detected threat, whether from a smoke sensor, motion detector, or door contact, is immediately met with a powerful deterrent.

Advanced Security and Reliable Protection
Equipped with a high-decibel sounder, the Heiman Indoor Siren produces a 95dB alarm (measured at 1 metre), ensuring it is clearly audible throughout your property. To provide a multi-sensory warning, the device features a bright, flashing circular LED ring, offering a clear visual indicator of an alarm event even in noisy environments. This dual-signalling approach is designed to maximise awareness and deter intruders effectively.
Uninterrupted Operation with Integrated Backup
One of the standout features of this smart siren is its integrated 3.7V/720mAh rechargeable backup battery. This ensures the device remains fully operational for up to four hours during a power failure or if the unit is deliberately removed from the wall socket by an intruder. This failsafe mechanism guarantees that your home security remains active and dependable at all times.

Utilising the latest Zigbee 3.0 protocol, the Heiman Indoor Siren offers superior compatibility and stability within your smart home network. It can be easily paired with a compatible Zigbee gateway, allowing users to create sophisticated automation scenes.
