Detailed specifications and benefits
The Superior MultiTransmitter Fibra board packs practical specifications intended for commercial and larger residential systems that require extensive wired device integration. Below are the technical details and the practical benefits they deliver.
With 18 wired inputs, the MultiTransmitter is suited to medium‑sized installations where a mix of detectors — intrusion, fire, gas, water/leak, panic buttons and specialised sensors — must be integrated into a single Fibra system. The board supports multiple wiring schemes (NC, NO, EOL, 2EOL and 3EOL) with EOL resistor ranges from 1 kΩ to 30 kΩ. This flexibility simplifies migration from legacy panels and enables installers to use a wide range of sensor types without complicated rewiring.
Communication with the Ajax hub uses the Fibra wired protocol over a 4‑core cable. U/UTP Cat.5 is recommended for best performance and reliability. Fibra provides encrypted two‑way signalling that improves resistance to tampering and ensures prompt, authenticated delivery of events and commands. For installations with long runs back to a hub or control room, the board supports up to 2,000 meters over Cat.5, minimizing the need for repeaters or additional network devices.
The board accepts 100–240 V mains input and allows for a backup 12 V battery (space for up to 7 Ah in the Case D enclosure). It supplies 10.5–15 V⎓ to connected detectors with a total output capacity up to 1 A and a dedicated fire detector line rated up to 0.4 A. These separate lines help ensure fire detection circuits remain powered and isolated per installation best practices. For installers, this means predictable power budgeting and the ability to host a diverse set of devices without overloading outputs.
The board includes a connector for an external tamper board and leverages Fibra to report tamper and anti‑sabotage events centrally. This is especially important in commercial installations where device accessibility must be monitored and any attempts at disabling devices reported immediately to the monitoring station or end user app.
Designed for indoor use (IP40), the board operates from −10°C to +40°C with up to 75% non‑condensing humidity. The product is supplied as a board only — a Case D enclosure is required for a complete installation (including battery mounting and mains connection). Compliance with CE/UKCA markings is referenced in Ajax documentation and the board carries a 24‑month warranty.
Practical benefits for installers and end users
- Simplifies integration of existing wired sensors into modern Ajax ecosystems — ideal for retrofits and phased upgrades.
- Reduces overall system complexity by centralising wired device inputs into a single Fibra link rather than multiple analogue channels.
- Long Fibra line runs cut down on infrastructure costs where hubs are remote from equipment rooms.
- Dedicated fire line and power budgeting features make compliance and reliability easier to achieve in safety‑critical installations.
- Remote configuration via Ajax apps saves time for onsite visits and allows rapid response to changes in system design or events.
Use cases and scenarios where the board excels
The Superior MultiTransmitter Fibra board is particularly strong in situations that require reliable bridging between wired devices and a modern wired IP‑style security backbone. Typical scenarios include:
Older office buildings and retail units frequently have existing wired detectors and alarm devices that are fully functional but incompatible with a new Ajax system out of the box. Installing the MultiTransmitter board allows these legacy devices to be integrated quickly without pulling new sensors, saving time and cost.
Projects that combine wireless Ajax devices with large numbers of wired detectors (for coverage in basements, plant rooms or areas with RF challenges) benefit from the board’s ability to centralise wired inputs into the Fibra network.
When detector groups are spread across large distances, the Fibra protocol’s support for long runs to a hub (up to 2,000 m) is a major advantage. This reduces the need for intermediate control panels and keeps management in the Ajax platform.
The dedicated fire detector power line and support for multiple EOL resistor schemes make the module suitable for integrating fire detectors into a monitored Ajax system while preserving required supervisory features.
Comparison with similar products on the market
Integration modules and multiplexers are common across security manufacturers, but the Superior MultiTransmitter Fibra board stands out for the following reasons:
- Fibra two‑way encrypted wired protocol — many competing modules rely on proprietary or unencrypted signalling when bridging to legacy systems.
- High zone density — 18 zones on a single board is competitive for mid‑sized installations, whereas some modules offer fewer zones and require multiple units for the same coverage.
- Long hub line support — 2,000 m to the hub (Cat.5) is generous compared with modules designed for short building runs only.
- Professional distribution and activation — Ajax restricts sales and activation to authorised partners, which helps ensure installations are performed to spec but may limit direct retail availability.
That said, alternatives from other manufacturers may include integrated housings (board plus enclosure) out of the box, or native support for different bus types. Choosing between these options depends on project scale, installer preference, and whether you prioritise an open retail purchase versus partner‑managed supply and activation.
Installer and customer feedback (anonymized)
There are limited public consumer reviews for a board‑only professional unit because the product is sold through authorised channels. Installer feedback gathered from training sessions and early deployments indicates several recurring positives:
- "Integration is straightforward and the multiple EOL options reduce rewiring on retrofit jobs." — Systems integrator (anonymized)
- "The dedicated fire line and clear power budgeting make compliance checks quicker on site." — Commercial installer (anonymized)
- "Long Fibra runs back to the hub saved us from installing extra equipment in the plant room." — Security project manager (anonymized)
These comments reflect practical benefits experienced by professionals; because sales and activation are channelled through authorised partners, end user-centric reviews are less common in public marketplaces.
