## Long description

The Ajax StreetSiren is a professional-grade wireless alarm device engineered for reliable security monitoring in both indoor and outdoor environments. Designed to provide immediate notification of security breaches, this siren combines a powerful piezoelectric buzzer with a high-visibility LED frame to ensure that alarms are both heard and seen. Its robust construction and weather-resistant design make it a dependable component for any residential or commercial security system.
Advantages
This wireless siren offers exceptional versatility through its dual power options, allowing it to run on pre-installed CR123A batteries for up to five years or via an external 12V DC power supply. The device features advanced anti-sabotage protection, including tamper detection that triggers an alert if the enclosure is opened or if an attempt is made to dismantle the unit. With an IP54 ingress protection rating, the siren is fully capable of withstanding harsh weather conditions, including rain, dust, and temperatures as low as -25°C. Furthermore, the system supports encrypted communication and jamming detection to ensure that the connection between the siren and the security hub remains secure and uninterrupted at all times.
Suitable for
Residential homes and apartments
Commercial offices and retail spaces
Warehouses and outdoor perimeter security
Monitoring security mode changes and alarm events
The Ajax StreetSiren may not be suitable for environments where extreme industrial noise levels exceed the siren's maximum output of 113 dB, as the alarm might not be clearly distinguishable. Additionally, it is not intended for use in areas where wireless signal transmission is completely blocked by thick lead-lined walls or massive metal structures that exceed the 1500-meter operating range.

What to consider before purchase
Ensure the installation location is within the 1500-meter range of your Ajax hub.
Verify if you require an external 12V power source for high-traffic areas.
