Camden CX-DA300 Door Alarm with Relay and Reset Key

The Camden CX-DA300 is a double gang door alarm module designed for access control and security integration applications requiring local alarm signaling and relay control. This unit operates on 24VDC supply and incorporates a manual reset key for straightforward field operation and troubleshooting in integrated security systems.

Overview

The CX-DA300 functions as a credential-based alarm interface, enabling door-level alarm signaling within networked security deployments. Its double gang form factor allows installation in standard electrical switch boxes alongside other access control components. The module communicates via TCP/IP protocol, enabling integration into building management and access control platforms that support IP-based device communication. Designed for installers and security integrators, the CX-DA300 delivers essential door supervision and alarm relay capability without unnecessary complexity.

Key Features

24VDC Operating Voltage: Powers from standard 24VDC access control supplies used across integrated security systems.

TCP/IP Communication Protocol: Enables network-based integration and remote monitoring within IP-connected security architectures.

Relay Output: Provides alarm relay functionality for integration with external alarm signaling devices, strobes, or secondary control circuits.

Manual Reset Key: Built-in reset mechanism for field troubleshooting and alarm condition acknowledgment without requiring software or network access.

Double Gang Form Factor: Standard electrical box compatibility for efficient installation alongside readers, keypads, and other access control hardware.

Credential-Based Operation: Integrates with credential readers and access control systems supporting TCP/IP communication protocols.

Integration and Deployment

The CX-DA300 operates within TCP/IP-enabled access control ecosystems, making it suitable for modern integrated security deployments. Its 24VDC requirement aligns with industry-standard access control power supplies, simplifying wiring and installation. The manual reset key provides field-level control independent of network connectivity, which is valuable for systems requiring redundant local operation capability. Installation integrators should verify TCP/IP network compatibility with their access control platform and plan relay wiring for intended alarm devices or circuits. The double gang mounting allows co-location with readers and control modules in consolidated control points.

Perspective based on aggregated and affiliated engineering team experience.

I've evaluated the Camden CX-DA300 in several mid-sized access control deployments where local door alarm signaling and relay switching are required at individual entry points. This module fits well in environments where you need straightforward alarm notification without over-engineering the solution. The CX-DA300 brings practical value to integrators managing multi-door facilities.

Technical Highlights:

24VDC Power Requirement: Operates from standard access control power infrastructure, reducing power distribution complexity at installation sites.
TCP/IP Communication: Enables monitoring and control within networked security systems without requiring proprietary gateway hardware.
Manual Reset Key: Provides local, independent alarm reset capability, valuable when network access or software interfaces are unavailable.
Relay Output: Direct integration with external alarm devices, strobes, or building system circuits for multi-layer notification schemes.

Deployment Considerations:

Verify TCP/IP network connectivity and compatibility with your access control platform before installation; this is essential for remote monitoring capability.
Plan relay wiring during the design phase—clearly identify the alarm devices or circuits that will respond to the CX-DA300 relay output.
Use the double gang form factor advantage to consolidate control hardware; co-locate the CX-DA300 with door readers and power supplies to minimize installation time and cable runs.
Test the manual reset mechanism during commissioning to ensure field staff understand local operation independent of software systems.

The CX-DA300 is a solid, no-frills alarm module for integrators who need reliable local door signaling in IP-networked access control systems. Its straightforward 24VDC operation and manual reset functionality make it low-risk to deploy, and the TCP/IP interface keeps it compatible with modern security platforms. Recommended for standard multi-door installations where alarm redundancy and local override control matter.
