Ajax LineSupply Fibra 45 W Auxiliary Power Module, 30 W + 15 W Charge, 82131.181.WH1

Introduction: what the Ajax LineSupply Fibra 45 W module is and why it matters

Ajax LineSupply Fibra 45 W (82131.181.WH1)is an auxiliary power and line‑extension module purpose‑built for Ajax Fibra wired security systems. It supplies a total of 45 W of power: 30 W dedicated to connected Fibra devices and 15 W reserved to charge a local 12 V backup battery (7–18 Ah supported). With one Fibra input and a galvanically‑isolated Fibra output, the LineSupply (45 W) can be installed downstream from the hub or another Fibra device to extend the Fibra bus by up to ~2,000 m per module over U/UTP Cat.5.

Key features at a glance

• 45 W total power: 30 W to connected Fibra devices + 15 W for a 12 V backup battery.
• Galvanic isolationbetween input and output to enhance safety and reduce interference.
• Line extension: extends Fibra runs roughly 2,000 m per module (Cat.5); modules can be combined for larger coverage.
• Protections: built‑in short‑circuit and overvoltage protection with automatic retry and recovery logic.
• Encrypted communication: two‑way encrypted device authentication on the Fibra bus.
• Designed for installers: intended for indoor installation inside an Ajax‑compatible case; commissioning by accredited partners recommended.

Detailed product specifications and benefits

• Primary input: 100–240 V AC, 50/60 Hz — compatible with standard mains supplies.
• Total power: 45 W, split as 30 W to Fibra devices and 15 W for battery charging.
• Backup battery support: Designed to charge a 12 V battery with capacity between 7 and 18 Ah (battery not included).
• Protections: Short‑circuit and overvoltage protection on signal lines; automatic recovery logic reduces downtime and limits maintenance visits.

• Line extension: Up to ~2,000 m per module when using U/UTP Cat.5 cable — ideal for long runs in commercial and large residential projects.
• Security: Two‑way encrypted Fibra communication and device authentication help ensure signals are tamper‑resistant and data remains private.

• Size & weight: 160 × 85 × 53 mm, approximately 456 g — compact enough for standard Ajax cases.
• Installation: Indoor use only, installed inside compatible Ajax cases (Case C (260) or Case D (430) recommended; sold separately).
• Operating conditions: −10 °C to +40 °C, up to 75% relative humidity.
• Warranty: 24 months.

Benefits explained: why those specs matter in real installations

• Localized power reduces voltage drop: Supplying power closer to devices minimizes voltage loss across long cable runs and keeps sensors and detectors operating reliably.
• Built‑in battery charging: The dedicated 15 W charging channel means remote nodes can maintain backup power locally without depending on the hub’s supply.
• Galvanic isolation improves safety: Isolating the output reduces the risk of ground loops and electrical interference between segments of the bus — important in mixed‑use buildings or where different electrical sources are present.
• Protection and auto‑recovery lower maintenance: Short‑circuit and overvoltage safeguards with automatic retries help avoid nuisance failures and reduce the need for immediate site visits.
• System compatibility and encryption: Purpose‑built for Ajax Fibra means simple integration, plus encrypted communication keeps the security signals protected.

Use cases and scenarios where LineSupply Fibra 45 W excels

In warehouses, manufacturing facilities or retail complexes with long corridors and large distances between devices and the central hub, a LineSupply module lets integrators place local power points and battery backup at intermediate nodes. This preserves device performance without running oversized cable back to the hub.

Campuses with outbuildings, annexes or multiple floors benefit from intermediate line extenders to bridge long distances. The galvanically‑isolated output helps when different buildings have separate grounding or supply issues.

High‑end homes with long property spans, detached garages or pool houses can use LineSupply modules to ensure sensors and detectors far from the hub get stable power and local battery backup for resilience.

Projects that favour a distributed power design — several smaller power nodes rather than a single central supply — can use multiple LineSupply modules to scale coverage while keeping each segment resilient and isolated.

How it compares to alternatives

When evaluating the LineSupply Fibra 45 W against other approaches, consider a few common alternatives:

• Standard central power supply with long runs: Centralised supplies risk voltage drop and require heavier gauge cabling for long distances. LineSupply reduces those issues by providing remote power points.
• Generic PoE injectors or PoE midspans: PoE is great for network devices but is not tailored for Ajax Fibra signalling or for 12 V battery charging. LineSupply is specifically made for the Fibra protocol, including encrypted communication and device authentication.
• Separate battery chargers and extenders: Using third‑party chargers plus passive extenders increases complexity, needs extra enclosure space and may not support galvanic isolation or auto‑recovery protections. LineSupply integrates these functions into a compact, installer‑friendly module.
• Other Ajax LineSupply variants: Ajax offers a family of power solutions. Compared to higher‑power modules, the 45 W version is a balanced choice for mid‑sized remote nodes — offering dedicated battery charging while keeping footprint and cost moderate.

In short, the LineSupply Fibra 45 W is optimized for Fibra systems where encrypted signalling, galvanic isolation, integrated battery charging and modest power distribution are needed. It is generally a better fit for Ajax installations than generic network power equipment.

Customer feedback and installer impressions

Official public testimonials specifically for this SKU are limited. However, feedback from professional installers working with Ajax systems (and with similar LineSupply modules) typically highlights a few common positives and considerations:

• Positives: Reliable remote power, easy integration into Ajax cases, tangible reduction in field failures caused by voltage drop, useful battery charging capability for remote nodes, and reduced need for costly cabling upgrades.
• Considerations: Requires an Ajax‑compatible case and a compatible battery (sold separately); commissioning by accredited installers is recommended which may add to initial setup cost; installer familiarity with the Fibra wiring and site planning is important to get the full benefit.

These impressions reflect generalized installer experience and product design intent rather than verbatim customer quotes.

Conclusion: who should choose the Ajax LineSupply Fibra 45 W?

The Ajax LineSupply Fibra 45 W (82131.181.WH1) is a focused solution for integrators and system designers who need to extend the reach of Ajax Fibra wired systems while providing local power and battery charging at remote nodes. Its key strengths are the dedicated 30 W device output plus a 15 W charging channel, galvanic isolation for safer line segmentation, robust protection and encrypted communications tailored to the Fibra protocol.
