## Long description

Ajax StreetSiren is a wireless siren designed for indoor and outdoor installation, providing audible and visual alarm signaling. The device has IP54 protection, operates in temperatures from -25°С to +50°С, and supports both battery (pre-installed CR123A) and 12 V⎓ backup power. StreetSiren notifies about alarms, tamper events, mode changes and door openings and can operate up to 5 years on the pre-installed battery. Maximum wireless range is 1500 m.
Advantages
The siren activates buzzer and LED frame in under a second when an alarm or tamper is detected. Its hermetically sealed body meets IP54 ingress protection for resistance to dust, hail and rain drops. Sound output is adjustable from 85 to 113 dB and the device can be set to operate silently with LED-only indication. Built-in authentication, jamming detection and encrypted communication increase reliability. Ready to use out of the box with pre-installed battery and one-click connection to the hub via mobile or desktop app; mounting with the SmartBracket panel takes only a few minutes.
