Overview
The SenTRI 2 Addressable Fire Alarm Panel is a highly capable, intelligent control solution designed to provide reliable fire detection and system management for a wide range of commercial and industrial environments. Developed by SMS (part of Honeywell), the panel supports flexible configurations and a broad selection of addressable devices, making it suitable for both new installations and system upgrades. Designed with ease of use and long-term performance in mind, the SenTRI 2 combines a clear, intuitive interface with powerful monitoring capabilities.
The panel supports single- or dual-loop configurations and can accommodate a large number of devices per loop, enabling comprehensive coverage of small to medium-sized buildings. With a modular design, it can be expanded and networked with additional panels, offering scalability for more complex sites. At its core, the SenTRI 2 is engineered for resilience and precision, incorporating soft addressing, built-in isolators, and advanced diagnostics to reduce downtime and streamline maintenance.
Its user interface features a clear backlit LCD display and discreet status indicators that only illuminate during active events, ensuring clear communication without visual clutter. The SenTRI 2 also integrates with repeater panels and remote indicators, supporting installation flexibility and enhanced control across larger premises. As a fully EN54-compliant system, it offers robust protection and peace of mind for building occupants and system integrators alike.
SenTRI 2 Core Features
The SenTRI protocol delivers high-speed, bi-directional communication, enabling rapid detection and response across complex installations. Its core features—soft addressing, built-in isolators, flexible zoning, and intelligent device mapping—ensure system resilience, simplified commissioning and precise control, making it one of the most powerful and adaptable fire alarm systems available today.
Enhanced Loop Power
The SenTRI 2 panel delivers 42V at 800mA per loop, providing significantly more power than many comparable systems. This increased capacity allows for a greater number of devices per loop, including power-intensive units like VADs. As a result, system designers can reduce the number of loops required, simplify wiring layouts and lower overall installation costs without compromising performance.
Device Allocation
The SenTRI 2 control panel supports up to 200 devices per loop, offering excellent scalability for medium to large installations. This high device capacity enables comprehensive coverage with fewer loops, reducing cabling requirements and making system design more efficient—particularly in complex buildings with varied detection and notification needs.
User Defined Programmable Controls
The SenTRI 2 control panel features flexible programming that allows users to configure custom controls tailored to site-specific needs. Programmed buttons and key switches can be assigned to trigger actions such as sounder isolation, door release or test modes. Calendar-based functions enable scheduled operations, providing automated control for timed events or occupancy-based settings.
Semi-Flush Mounting
The SenTRI 2 can be semi-flush mounted using a dedicated bezel kit, allowing for a neater, low-profile installation while maintaining full access to controls and indicators.
Loop Wired Functional Repeater Panel
The SenTRI 2 control panel supports loop-wired functional repeater panels, allowing them to be powered and communicate directly via the existing detection loop. This eliminates the need for separate power supplies or data cabling, simplifying installation, reducing costs and ensuring seamless integration across multiple building locations.
Robust Network
The SenTRI 2 can be networked with up to 31 other control panels, creating a robust system that allows full communication and control across large or multi-building sites. This networking enables event sharing, global cause-and-effect programming and centralised monitoring, ensuring a coordinated response and seamless system-wide operation.
