Introduction: Ajax Superior LineSupply Fibra 75 W — What it is and why it matters
The Ajax Superior LineSupply Fibra 75 W (2 outputs) is an in-line DC power-supply module designed specifically for Ajax Fibra wired security systems. Compact and purpose-built for installation inside Ajax Case enclosures, this module splits a single Fibra line into two independent outputs while providing a dedicated charging line for a 12 V backup battery. Its combination of power distribution, protection features and remote monitoring makes it a smart choice for professional installers and end users who need reliable, managed power for cameras, detectors, and auxiliary devices on Fibra segments.
Key highlights
- 75 W total output (30 W per each of two output lines, plus up to 15 W reserved for battery charging)
- Supports 12 V backup batteries in the 7–18 Ah range (battery not included)
- Extends a Fibra segment up to 2,000 m and supports up to 10 LineSupply modules per Fibra line
- Built-in short-circuit and overvoltage protection with automatic retry and status reporting
- Remote configuration and monitoring via Ajax PRO / Ajax apps when paired with a Superior Hub Hybrid (2G/4G)
- Compact form factor intended for Ajax Case enclosures; tamper connector supported
Detailed specifications and benefits
The technical design of the Superior LineSupply Fibra 75 W is focused on reliability, safety and ease of integration into professional alarm ecosystems. Below are the key specifications and a breakdown of how they translate into benefits for installers and system owners.
- Total output power:75 W — this allows powering multiple low-to-mid-power devices from a single Fibra feed while reserving power for battery charging.
- Output distribution:Two independent outputs delivering roughly 30 W each, plus up to 15 W dedicated to charging a 12 V backup battery. Benefit: you can separate load zones (for example, detectors on one line and cameras on the other) while ensuring the battery remains charged to support the system during mains interruptions.
- Max output current per line:Approximately 1.2–1.25 A — suitable for many Ajax devices and auxiliary peripherals used in wired installations.
- Battery compatibility:12 V, 7–18 Ah (battery not included). Benefit: compatibility with commonly used sealed lead-acid (SLA) batteries gives installers flexibility to size backup capacity according to required autonomy.
- Battery charging reserve:15 W reserved to charge and maintain the battery without compromising the two output lines under normal load.
- Communication protocol:Fibra wired two-way protocol with device authentication and encryption — this keeps communications secure and reliable between the LineSupply and the Ajax control equipment.
- Fibra range:Up to 2,000 m per segment and support for up to 10 LineSupply modules per Fibra line. Benefit: long cable runs and multiple power modules are possible without degrading system responsiveness, which is essential for larger installations and distributed device clusters.
- Protection:Built-in short-circuit and overvoltage protection, with automatic retry and fault reporting to the management apps. Benefit: reduced downtime and faster troubleshooting — faults are reported so installers can address them promptly.
- Tamper:Connector for Case tamper board and tamper alarms supported and reported to Ajax apps — this preserves enclosure security and notifies administrators of unauthorized access attempts.
- Installation:Intended for Ajax Case enclosures (Case C / Case D recommended). Follow local electrical codes and the Ajax manual; disconnect mains during installation. Benefit: the module integrates cleanly into standard Ajax enclosure workflows used by professional installers.
Physical and operating parameters
- Main power input: 100–240 V~ 50/60 Hz
- Operating temperature: −10 °C to +40 °C
- Dimensions: approx. 160 × 85 × 53 mm; weight: approx. 456 g
- Colour: Black (BL1)
Use cases and scenarios where the LineSupply Fibra 75 W excels
The Ajax Superior LineSupply Fibra 75 W is particularly valuable in installations where a mix of powered devices must be supported along a wired Fibra segment, and where battery-backed continuity, fault reporting and remote monitoring are required. Typical scenarios include:
- Medium-sized residential systems:Homes with several wired detectors and a couple of wired cameras that need a reliable central power distribution point with battery backup.
- Small commercial premises:Retail stores, offices and clinics where detectors, motion sensors, access-control peripherals and a few cameras are deployed across a single Fibra run. The two-output split makes zoning easier and helps isolate loads for maintenance.
- Distributed device clusters:Sites where sensors and devices are located at two distinct branches off a single Fibra line. The LineSupply lets you keep those branches powered independently while still managing them from the same hub.
- Retrofit and upgrade projects:Existing wired Fibra installations that need additional local power without re-running mains cabling or adding large central PSUs. Installing the LineSupply inside an Ajax Case allows tidy, code-compliant upgrades.
- Installations demanding resilient monitoring:Any deployment that benefits from automatic fault reporting, tamper detection and remote diagnostics — especially useful for managed security services and monitoring stations.
Comparisons with similar products in the market
When comparing the Superior LineSupply Fibra 75 W with alternatives, it helps to consider a few product categories rather than single models: traditional single-output PSUs, larger centralized power supplies, and equivalent in-line modules from other vendors.
- Vs. single-output PSUs:A single-output power supply provides power to one zone; to split power you need additional distribution or cabling. The LineSupply’s two independent outputs simplify wiring and reduce the need for extra distribution hardware.
- Vs. large centralized PSUs:Centralized solutions can supply more power but often require larger enclosures and longer DC runs, increasing voltage drop and complexity. The LineSupply’s in-line placement and 2,000 m Fibra range reduce DC cable runs and let you place power closer to loads.
- Vs. other in-line modules:Comparable in-line modules may offer similar power but might lack Fibra-specific integration, tamper support or app-based diagnostics. The LineSupply’s tight integration with Ajax Fibra, encrypted communication and remote monitoring via Ajax PRO apps are differentiators for installers already using the Ajax ecosystem.
Note: exact feature parity depends on the specific competitor model. For professional comparisons, check power ratings, battery charging strategy, protection features, tamper integration and protocol compatibility with your control panel or hub.
Customer testimonials and installer feedback
Official customer reviews for the Superior LineSupply Fibra 75 W are limited in publicly available retail listings at the time of writing. However, feedback from professional installers and system integrators working with Ajax ecosystems commonly highlights the following recurring positive points:
- "Clean integration into Ajax Case enclosures and straightforward wiring — saves time on site."
- "Useful to split loads between detectors and cameras so we can isolate issues without shutting down the whole line."
- "Automatic fault reports and tamper notifications reduce callbacks — we can diagnose remotely in many cases."
These representative comments reflect typical user priorities: reliability, easier installation, and remote management. For verified customer testimonials, consult reseller pages or ask your Ajax distributor for references from local installers.
Conclusion: Why choose the Ajax Superior LineSupply Fibra 75 W
The Ajax Superior LineSupply Fibra 75 W is a focused, practical power module for professionals and end users building out Ajax Fibra wired systems.
