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. What’s more, it has a Chime1 feature and alerts users to delays when they are entering or leaving. 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 circuit, spoofing, and line breakage2. The siren can offer reliable protection indoors and outdoors and remote control via Ajax apps.
