Ajax StreetSiren Fibra White Wired Outdoor Siren with LED Indication

Ajax StreetSiren Fibra White Wired Outdoor Siren

The Ajax StreetSiren Fibra is a wired siren built for the Ajax Fibra product line, combining loud audible alerts with bright LED signalling to warn of intrusions and deter would-be offenders. Designed for both indoor and outdoor mounting, it communicates with a compatible Ajax hub over the secure, two-way Fibra wired protocol, giving installers a robust alternative to radio-based sirens for sites where cabled reliability is preferred. Its weatherproof white housing suits shopfronts, warehouses, offices, and residential exteriors alike.

Key Features

• Adjustable sound output from around 85 dB up to 113 dB, tunable to suit the installation site
• Fibra wired protocol for encrypted, two-way communication between the siren and hub, resisting spoofing and sabotage attempts
• Long cable run support, with a communication range of up to 2,000 metres over U/UTP Cat.5 twisted pair cabling
• Bright LED frame that displays arming status, entry/exit delays, and after-alarm information
• Built-in backup battery charged from the Fibra line, keeping the siren operational if the line is cut or power is lost
• IP54-rated, weatherproof enclosure suitable for outdoor use in a wide temperature range
• Anti-sabotage protection, alerting if the unit is removed from its mounting or tampered with
• Door-opening chime function, useful for notifying staff of visitor entry while the system is disarmed
• Remote configuration of volume, tones, and behaviour via the Ajax mobile and PRO apps

Reliable Wired Alerting for Homes and Businesses

Because it runs on a dedicated wired Fibra line rather than radio, the StreetSiren Fibra suits properties where cable runs are practical or preferred, such as retail premises, offices, and larger residential installations with existing wired infrastructure. Paired with an Ajax hub supporting Fibra, it delivers dependable audible and visual alarm signalling, everyday status indication, and business-friendly features like the visitor chime, all backed by encrypted communication designed to resist tampering.
