The TrolMaster SPH-1 is a powered RJ12 splitter hub designed to expand the connectivity of Hydro-X, Hydro-X Pro, Hydro-X Plus, and Carbon-X control systems. It accepts one RJ12 connection from the main controller and provides 8 individual RJ12 output ports for connecting sensors, device stations, lighting adapters, and other compatible TrolMaster modules. Unlike a passive splitter, the SPH-1 actively boosts/regenerates the signal and provides supplemental 12V power for compatible devices.
• SKU: SPH-1

• Dimensions: 160 × 85 × 90 mm
• Compatible Devices: TrolMaster sensors, device stations, lighting adapters, CO₂ stations, smoke detectors, and other compatible RJ12 modules
• Multiple Hubs: Multiple SPH-1 hubs can be used within a TrolMaster system, subject to the controller-specific device limits
• Special Requirement: Required for supplemental 12V power for certain modules, including the MBS-Pro sensor
• Installation: One RJ12 cable from controller → SPH-1 → up to 8 downstream devices
• Important Lighting Note: When used solely to connect multiple lighting adapters back to one LMA adapter, the 12V power supply may need to remain disconnected depending on the specific lighting-adapter configuration
• In the Box: 1× SPH-1 hub, 1× 16-ft RJ12 cable, 1× 12VDC power supply
Key Advantage: The SPH-1 changes a simple single RJ12 connection into an 8-port powered hub while actively regenerating the signal, making it more suitable than passive Y-splitters for larger installations with multiple sensors, device stations, and lighting adapters. It also provides the supplemental power required by certain TrolMaster modules.
