Description

The Honeywell XLS140-CPU2E is the central processing unit (CPU) module acting as the primary control core for the Honeywell XLS140-2 intelligent addressable fire alarm control panel (FACP) system. Operating as the operational brain of the lifecycle safety network, it executes time-critical boolean equations, processes sensor data maps, and coordinates notification appliance circuits (NACs). The “E” suffix indicates integrated network configuration capabilities, permitting direct IP network communication paths for remote system programming, diagnostics, and seamless integration with Honeywell Enterprise Buildings Integrator (EBI) platforms.

Technical Specifications and Performance Limits

The XLS140-CPU2E handles processing requirements across local building deployments or multi-node networked facilities.

Loop Architecture and Device Capacity

• Signaling Line Circuits (SLC): 1 isolated intelligent loop base configuration, expandable to 2 loops using expansion interface hardware.
• Device Address Density: Supports up to 159 addressable detectors (any blend of photoelectric, ionization, thermal, laser, or multi-sensor instruments) and 159 addressable modules (pull stations, monitoring switches, relay elements) per loop.
• Maximum Total Points: Up to 318 addressable devices per node.

Communications and Digital Protocols

• Signaling Protocol: Native FlashScan digital communication matrix. It samples and polls up to 318 distinct physical device nodes in less than 2 seconds and can trigger up to 159 output channels within 5 seconds.
• Network Interfaces: 1 x integrated RJ45 Ethernet port for network management utility uploads/downloads. Dual EIA-485 interfaces support remote serial annunciators and terminal layout options. 1 x isolated EIA-232 port handles local printer hardware connections.
• Event Log Memory: Houses a non-volatile history log containing an 800-event facility record space alongside a separate, dedicated 200-event alarm-only history cache.

Electrical and Safety Parameters

• Supply Voltage: 24 V DC (nominal continuous filtering power bus).
• Relay Outputs: 4 onboard physical relays mapping directly to Alarm, Trouble, Supervisory, and Security alarm status configurations.
• Degraded Operation Mode: Microprocessor safety fallback design. If a terminal component failure disrupts primary CPU processing operations, the system drops into degraded mode, enabling basic localized FlashScan detector loops to directly toggle localized notification appliance circuits (NAC) and alarm relays to maintain building coverage.

System Integration and Compliance Constraints

Critical Life Safety Installation Rule: System changes, logic overrides, and baseline firmware updates must be compiled using Honeywell VeriFire Tools software utilities. Mismatching application revisions between the CPU configuration database and external network annunciator displays (e.g., XLS-NCA2) will generate a critical network node mapping failure block.

• Network Topologies: The CPU module supports scaling via standard-speed network interfaces for up to 103 system nodes, or high-speed fiber configurations tracking up to 200 active nodes (interlinking XLS140, XLS140-2, XLS3000, and XLS-DVC audio subsystems).
• Environmental Profiles: Designed to sit inside standard Honeywell CAB-4 or specialized marine-rated CAB-M enclosure frames. It operates across standard room temperature ambient values; always verify regional moisture limits against the underlying OEM datasheet during design specification phases.
• Regulatory Framework: Compliant with NFPA 72 compliance testing routines, carrying explicit UL Listing (S470), ULC Listing (S7564, S7566), and California State Fire Marshal (CSFM) registry clearances.

Frequently Asked Questions (FAQ)

Can the XLS140-CPU2E be used as a direct drop-in replacement for an older non-E XLS140-CPU?

Yes, the hardware footprint is physically compatible. However, adding the “E” variant opens integrated network programming properties that require configuring matching IP tables via VeriFire Tools. Additionally, check that your pre-existing peripheral modules (like loop interface cards or display panels) support the baseline firmware requirements of the newer generation CPU2 platform.

What is the exact difference between the XLS140-CPU2E and the Honeywell XLS3000 processing module?

The XLS140-CPU2E is targeted at medium-scale facilities, maxing out at a 2-loop architecture (318 total addressable points). The XLS3000 is built for large, heavy campus structures, supporting 1 to 10 expandable Signaling Line Circuits (SLCs) for an aggregate total of up to 3,180 addressable intelligent nodes on a single control engine.

How is the localized backup power calculated for this processing core?

The CPU module draws from the master enclosure’s integrated charging controller bus (supporting 18 AH up to 200 AH lead-acid gel cells). The required standby capacity must be formally mapped via power consumption worksheets, proving a continuous 24-hour baseline monitoring life followed by a 5-minute continuous notification strobe load cycle under NFPA-72 standards.
