Ajax Superior LineSupply Fibra 75 W Power Module, 2 Outputs, 117733.181.WH1

Introduction to the Ajax Superior LineSupply Fibra 75 W Power Module

The Ajax Superior LineSupply (Fibra) — model 117733.181.WH1 — is a professional wired power module designed to extend the capabilities of Ajax Fibra security installations. In a compact white enclosure, this module splits a single Fibra line into two output lines and supplies up to 75 W of additional power to devices on the line while maintaining compatibility with the secure Fibra wired protocol. Built for installers and system integrators, the LineSupply adds power distribution, battery charging support and robust protection features that simplify the deployment of larger or geographically spread wired security systems.

Key features at a glance

• High total output:up to 75 W total (distributed as 30 W per output plus 15 W reserved for backup battery charging).
• Dual outputs:splits one input Fibra line into two output lines for flexible system design.
• Long distance support:each output can support runs up to 2,000 metres, and chaining up to 10 modules can extend reach to roughly 22 km.
• Protection and reliability:galvanic isolation, short‑circuit and surge/overvoltage protection, and passive ventilation for silent, maintenance‑free operation.
• Backup battery support:12 V DC connector for a 7–18 Ah battery (battery not included) to maintain system uptime during mains loss.
• Professional installation:designed for use with Ajax Superior Hub Hybrid (Fibra) and recommended for partner installation due to its wired nature and safety requirements.

Detailed specifications and benefits

• Model / part number:117733.181.WH1
• Product:Superior LineSupply (Fibra) — 75 W
• Colour:White

• Input (mains):100–240 V AC, 50/60 Hz — wide input range makes the module suitable for most global mains supplies without extra configuration.
• Total output power:75 W — enough to power multiple Fibra devices such as detectors, keypads, and external peripherals when appropriately distributed.
• Output distribution:30 W per output with an additional 15 W reserved for battery charging — enables a predictable split of available power while preserving capacity for backup battery maintenance.
• Backup battery:12 V DC connector supporting 7–18 Ah batteries — straightforward support for a battery that will keep critical devices running during mains outages.
• Lines:1 input line and 2 output lines — simplifies wiring topologies where a single hub line must serve two separate branches or zones.
• Bus connection / cable:4‑core cable recommended; U/UTP Cat5 twisted pair is advised for long runs to ensure signal integrity and power delivery.

• Max cable distance:Up to 2,000 metres per output — supports long-distance deployments such as warehouses, campuses and multi-building sites; chaining up to 10 LineSupply modules can extend coverage to ~22 km.
• Protection:Includes galvanic isolation and protection against short circuits and surge/overvoltage events — protects both the LineSupply and connected Fibra devices, improving system reliability and reducing maintenance costs.
• Ventilation:Passive ventilation — a silent solution that avoids moving parts and reduces failure points associated with fans.

• Operating temperature:−10 °C to +40 °C — suitable for many indoor commercial and residential environments.
• Dimensions:Approx. 160 × 85 × 53 mm — compact footprint that fits into control rooms, cabinets or enclosure panels.
• Weight:Approx. 456 g — lightweight for easy mounting.

• Compatibility:Designed for Ajax Superior Hub Hybrid and Fibra wired devices — ensures seamless integration with Ajax wired security ecosystems.
• Installation:Professional/partner installation recommended — wiring, battery selection and compliance work are best handled by authorised installers familiar with Ajax Fibra standards.

Benefits: what this product brings to installers and end users

• Flexible distribution:Splitting a single line into two outputs reduces the need for additional hubs or complex cabling, saving time and materials on site.
• Improved uptime:Built‑in support for a backup battery maintains critical security functions during power outages.
• Scalability:Long run capability and the ability to chain modules make it easier to expand coverage across large or segmented properties without sacrificing signal integrity.
• Safety and longevity:Galvanic isolation and surge protection reduce the risk of component damage and false alarms caused by electrical disturbances.
• Professional reliability:Designed and specified for partner installation, the LineSupply meets the expectations of commercial installations where reliability and compliance matter.

Use cases and scenarios where the LineSupply excels

The LineSupply is particularly well suited to installations where power distribution, long cable runs and reliable protection are required. Typical scenarios include:

• Commercial buildings and retail complexes:When multiple devices across different floors or zones must be powered from a single Fibra line, the two outputs streamline distribution while preserving battery charging capability for emergencies.
• Warehouses and industrial sites:Large floor areas and long cable runs benefit from the LineSupply’s 2,000‑metre per output reach and robust protection against surges and short circuits.
• Multi‑building campuses:By chaining LineSupply modules, installers can extend Fibra coverage across outbuildings or detached structures without adding excessive central infrastructure.
• Renovations and retrofits:In buildings with existing wiring constraints, the LineSupply allows a single feed to serve multiple branches, reducing new cabling work and simplifying upgrades.
• Critical infrastructure:Sites that require uninterrupted operation (medical facilities, financial premises, data centers) can combine the LineSupply with appropriate backup batteries to increase resilience during mains outages.

How the LineSupply compares to similar products

When evaluating power distribution options for wired security systems, installers commonly consider single‑output power supplies, generic DC power modules, PoE injectors and other brand power splitters. The Ajax Superior LineSupply stands out for several reasons:

• Purpose‑built for Fibra:Unlike general DC splitters, the LineSupply is integrated with the Fibra protocol and Ajax ecosystem, ensuring compatibility and predictable behaviour with Fibra devices.
• Power and distribution balance:Its 75 W total output (30 W per output + 15 W battery reserve) is higher than many simple splitters, making it better suited for powering multiple devices on each line while reserving capacity for battery charging.
• Distance capability:The 2,000‑metre per output reach and capacity to chain modules exceeds typical consumer power supplies and many off‑the‑shelf splitters that are not designed for long‑distance wired security buses.
• Protection features:Galvanic isolation and built‑in surge/short‑circuit protection reduce the need for external protection devices and lower the risk of system damage from electrical faults.
• Professional focus:Many competing products target DIY or generic networking markets; Ajax LineSupply is engineered for professional integrators, with installation guidance and a safety focus suitable for regulated commercial work.

Conclusion: why the Ajax LineSupply Fibra 75 W is a strong choice

For professional integrators and installers working within the Ajax Fibra ecosystem, the LineSupply 75 W module offers a balanced, reliable and scalable solution for powering wired security devices. It combines meaningful power capacity, dual output flexibility, long‑distance support and comprehensive electrical protection — features that reduce installation complexity and increase system resilience. Passive ventilation and a compact form factor make it straightforward to deploy in control rooms or cabinets, while backup battery support ensures continuity for critical systems.

If your project requires splitting a Fibra line, powering multiple devices across long runs, or adding battery backup capability to a wired Ajax installation, the LineSupply is engineered to meet those needs.
