PRODUCT DETAILS

The Ajax Superior StreetSiren Plus Fibra is a high-performance wired external siren designed for Grade 3 security installations that require maximum reliability, rugged construction, and fast alarm signalling. As part of the Ajax Superior range, it offers advanced features and expanded functionality while communicating via the secure Fibra wired protocol, ensuring stable, encrypted two-way communication up to 2 km from the hub. 

Built for professional outdoor use, the Superior StreetSiren Plus Fibra is the next level of signaling alarm and events in an Ajax security system. Featuring selectable alarm tones and impossible-to-miss LED indication, the device deters intruders, displays system security status, and provides an after-alarm indication. Moreover, it has a Chime1 feature that alerts users to delays when they enter or leave. The siren has a powerful wired communication range of up to 2,000 m without line extenders, additional power supply during an alarm, and multi-layered sabotage protection. A single Fibra line can accommodate up to 10 sirens and is protected against short circuits, spoofing, and line breakage2. The siren can offer reliable indoor and outdoor protection and remote control via Ajax apps.
