Performance data for the Calltou Wireless Call Button System indicates a high-availability RF solution utilizing the 433.92MHz frequency. The system uses On-Off Keying (OOK) signaling to achieve a theoretical line-of-sight range of 500 to 1,000 feet, though residential structural attenuation typically limits the effective operational radius to 150-200 feet.
The transmitters are IP55-rated and powered by CR2032 coin cells designed for long-term standby. The receiver is an AC-powered unit that functions independently of internet connectivity, providing a trigger-to-chime response time of less than 100ms. Technical analysis confirms the lack of cloud logging, which prioritizes immediate reliability over digital data collection.
Standardized testing suggests that the superheterodyne receiver may be desensitized if placed in close proximity to high-frequency noise sources such as microwave ovens or Wi-Fi routers. The hardware is a stable ODM design focused on button membrane durability.
- Response Time: <100ms
- Signal Type: 433.92MHz OOK
- Transmitter Power: CR2032 Lithium Cell
Operational logic dictates that the caregiver must be within audible range of the chime, as the system does not support native integration with smart home ecosystems like Alexa or Google Home.
For users requiring the ability to receive alerts on a mobile device, the Senckit Smart Wi-Fi Siren Alarm offers the necessary cloud connectivity.
This unit is a localized component of the wireless sirens and panic buttons category.
