What is the 6000/LP4IO?

In simple terms, the LP4IO is a loop-powered, 4-channel input/output interface. It was developed to offer a compact, multi-channel solution that doesn’t require an external power supply. And instead takes all its power directly from the Protec 6500 digital addressable loop.

The LP4IO addresses a common challenge in fire alarm system design: the need to install multiple separate interface units to handle various input and output signals. This approach often leads to increased hardware costs, extended installation time, and added complexity in wiring and commissioning.

By consolidating four configurable channels into a single, intelligent interface, the 6000/LP4IO delivers a more streamlined solution that:

• Reduces hardware requirements
• Cuts down installation time
• Minimises enclosure and wiring needs
• Simplifies ongoing maintenance and commissioning

The result is a more efficient and cost-effective installation process, along with improved reliability and easier system integration for the end user.

Smart, Compact System Integration

6000/LP4IO sits directly on the Protec digital addressable loop and acts as a vital link between Protec’s current generation multi loop fire alarm control panel (6500 series) and external systems such as gas detection, lift controls, ventilation, and gas shut-off valves.

With four independently configurable Address channels, the LP4IO can monitor inputs from devices like gas or water leak detectors and control outputs to systems such as fans or gas valves. This allows the fire alarm system to respond automatically and trigger a gas shut-off, initiate extraction systems, or grounding lifts when needed without the need for manual intervention.

Each input and output are fully monitored and programmable via the Protec commissioning software, using the 6500’s cause and effect matrix or Boolean logic. The device is then managed via the 6000PLUS protocol, which provides real-time status updates across the addressable loop. Designed for safety-critical applications, the 6000/LP4IO enhances control, coordination, and responsiveness across building systems during fire and emergency events.

Typical Applications

The LP4IO’s flexibility makes it suitable for a wide range of applications, some of these include:

Gas Detection Shutdowns – Triggering isolation valves in response to fire detection.

Lift Grounding – Automatically bringing lifts to ground level and disabling them during a fire alarm.

Fan Control – Activating extraction or pressurisation systems based on specific input conditions.

Water Leak Detection – Monitoring signals from leak detectors and alerting or isolating affected zones.

Lockdown/Invacuation Inputs – Allowing non-fire inputs, such as lockdown call points, to trigger programmed building responses.

Why Choose the Protec 6000/LP4IO?

Integrating multiple systems used to mean multiple interface units. The LP4IO simplifies this by combining up to four channels into one loop-powered device, reducing:

Hardware Requirements – Fewer devices to install

Cabling – One loop connection instead of several

Configuration Time – Less programming and wiring

Risk of Error – Simplified installation means fewer mistakes

Cost – Reduced devices mean less cost in time, materials and products.

Whether you’re managing a complex building services integration or looking to reduce hardware across your next project, the Protec 6000/LP4IO offers a smart, efficient solution. With its loop-powered design, flexible configuration, and seamless integration with third-party systems, it supports safer, smarter buildings without the complexity.
