Ajax StreetSiren DoubleDeck Fibra Black Wired Outdoor/Indoor Siren

Ajax StreetSiren DoubleDeck Fibra Black Wired Siren

The Ajax StreetSiren DoubleDeck Fibra is a hardwired siren built for both indoor and outdoor deployment as part of an Ajax Fibra security ecosystem. Finished in black, it combines a loud piezoelectric alarm with a bright LED frame to give installers a dependable, cable-connected alerting device that isn't affected by radio interference or building obstructions. Its DoubleDeck design allows a clip-on Brandplate faceplate to be fitted, letting monitoring or installation companies turn the siren into a branded promotional surface as well as a deterrent.

Key Features

• Wired Fibra connectivity: Communicates with a compatible Ajax hub over a secure, encrypted Fibra line rather than radio, ideal for sites with heavy interference or metal structures.
• Loud, adjustable sound output: Delivers alarm volume from roughly 85 dB up to 113 dB at one metre, with adjustable duration configured through the Ajax app.
• Bright LED alarm frame: Provides clear visual indication of alarm state, security mode, and entry/exit delays alongside the audible signal.
• Long cable run support: Supports Fibra line lengths of up to 2,000 metres using standard U/UTP Cat.5 twisted-pair cabling.
• Backup battery protection: A built-in battery keeps the siren indicating alarms even if the Fibra line is cut or main power is lost.
• IP54-rated sealed enclosure: Resists dust and splashing water, and is rated to perform reliably across a wide temperature range from roughly -25°C to 60°C.
• Tamper and sabotage detection: Triggers an alert if the unit is removed from its mount or the casing is opened or damaged, identifying exactly which siren was targeted.
• Brandplate-ready design: Accepts an optional clip-lock Brandplate faceplate (sold separately) for custom branding and marketing.
• Low-power TDMA communication: Uses time-division data exchange with the hub to reduce power draw and minimise interference between multiple Fibra devices.

Reliable Wired Alerting for Demanding Sites

This siren suits homes, offices, warehouses, and commercial premises where a hardwired connection is preferred for reliability, or where metal enclosures and long distances make wireless sirens impractical. It pairs with compatible Ajax hub models to deliver instant audible and visual alerts triggered by intrusion, fire, water leak, or other connected detectors, while sending real-time notifications to the Ajax mobile app.
