Product Overview

The DO-EC05 Alarm Output and Integrated Fire Control Expansion Controller is a specialized add-on module designed for access control systems requiring fail-safe fire alarm integration and multi-zone alarm output management. This expansion panel enables system integrators and project contractors to consolidate fire control signaling, intrusion detection response, and door lock coordination into a single, offline-capable access control architecture. Instead of deploying separate alarm panels and fire relay boards, the DO-EC05 provides a unified hardware interface that communicates directly with the host access controller, reducing wiring complexity, panel enclosure requirements, and per-door installation cost.

Commercial facility managers, security system distributors, and industrial safety officers choose this module when they need to comply with fire code requirements for automatic door release without replacing their existing access control infrastructure. The board accepts four independent alarm input channels and delivers four programmable relay output channels, each configurable for event-specific responses such as forced entry alerts, prolonged door open warnings, duress entry triggers, invalid credential notification, and fire emergency unlocking. By centralizing these functions on one expansion board, the system reduces the number of enclosures, power supplies, and communication cables required per deployment, which directly lowers hardware procurement costs and installation labor for large-scale projects.

Product Advantages

The DO-EC05 delivers measurable commercial value for security integrators and wholesale buyers who need repeatable, code-compliant fire alarm integration across multiple sites. Its primary advantage is the elimination of separate fire control panels for access-controlled doors. When a fire alarm signal is received on any of the four input channels, the module automatically triggers all connected doors to unlock, ensuring egress compliance without requiring additional fire relay modules or centralized fire alarm panel integration. This single-board approach reduces bill-of-materials cost per door by approximately 30 percent compared to deploying standalone fire alarm interface boards for each controlled opening.

For system integrators managing multi-building campus deployments or retail chain rollouts, the ability to define which alarm outputs correspond to which doors within the software provides deployment flexibility without hardware reconfiguration. The 0-to-6000-second programmable output delay allows tailoring door release timing to specific egress scenarios, such as staggered unlocking in high-security zones or delayed relocking after fire alarm reset. Distributors and project contractors benefit from the module’s compatibility across multiple DO RFID Reader controller models, which simplifies inventory management—one expansion board SKU serves various site requirements rather than stocking model-specific boards for each controller variant.

Manufacturing consistency is another core advantage. As a factory-produced expansion module, each DO-EC05 board undergoes in-house functional testing of all four input channels, four relay outputs, and communication handshake with the host controller before shipment. This batch-level quality assurance ensures that bulk orders for multi-site deployments receive identical performance characteristics, eliminating site-to-site variation in alarm response timing or relay switching reliability. For OEM customers, the board’s straightforward interface enables rapid integration into custom enclosure designs or branded security solution kits without requalifying the entire access control system.

Key Features

• Four-Channel Alarm Output with Programmable Assignment – Each of the four relay outputs can be independently assigned to any door or door group controlled by the host access controller. This allows site-specific alarm response mapping without hardware jumper changes.
• Integrated Fire Control Interface – Direct connection to fire alarm panels or manual pull stations. Upon receiving a fire signal, the controller automatically unlocks all doors in the affected zone and generates a time-stamped fire alarm event record for post-event review and compliance documentation.
• Multi-Event Alarm Linkage – Supports programmable output triggers for illegal intrusion, prolonged door open (adjustable 0–6000 seconds), duress entry, valid card link-open, invalid card attempt, and fire alarm. Each event type can activate one or more relay outputs independently.
• Per-Output Delay Configuration – Each relay output channel supports independent delay timing from 0 to 6000 seconds, enabling sequenced door unlocking, delayed alarm notification, or staged egress coordination.
• Duress Entry Detection with Password Change Support – Authorized users can change the anti-intimidation password through the software interface. When a duress credential is used, the module triggers the assigned alarm output silently without alerting the person at the door.
• Compatibility with DO-2000 Series Controllers – Works with DO-WG01, DO-WG02, DO-WG04, DO-T01, DO-T02, DO-T04, DO-RS01, DO-RS02, and DO-RS04 access controllers for unified system architecture.
• Software Requirement – Requires management software version V6.6 or higher to support full alarm output and fire control configuration.
• Status Indication – Onboard power and relay status LEDs provide immediate visual confirmation of module operational state and communication link integrity with the host controller.

Technical Specifications

Industrial Applications

The DO-EC05 is deployed in commercial, industrial, and institutional environments where fire code compliance and multi-zone alarm monitoring must operate within a unified access control framework. Typical installations include office building perimeter doors, manufacturing facility emergency exits, warehouse personnel gates, laboratory restricted areas, data center server room entrances, and educational campus secure zones. System integrators use this module when retrofitting existing access control systems to meet updated fire safety regulations, as the board integrates directly with the existing controller without requiring new head-end hardware or rewiring of the entire door network.

For facilities with mixed-security zones, the per-door programmable alarm assignment enables a single expansion board to serve both high-security areas requiring immediate lockdown on intrusion detection and general access areas where only fire alarm unlock is needed. Industrial plant safety managers value the long-duration door-open alarm feature for monitoring dock doors or equipment access points that must not remain unsecured beyond a set time window. The four-input design also supports connection to auxiliary sensors such as window contacts, motion detectors, or glass break sensors, allowing the access control system to double as a basic intrusion detection panel without purchasing a separate security system.

Large-scale deployment projects—such as multi-tenant office towers, hospital campuses, or government facilities—benefit from the module’s consistent behavior across hundreds of doors. Because each DO-EC05 is factory-tested and follows the same firmware logic, site acceptance testing proceeds faster and troubleshooting is simplified. Wholesale buyers supplying security contractors across multiple regions can stock one expansion board model that works with multiple controller types, reducing inventory carrying costs and eliminating the risk of shipping incompatible hardware to job sites.
