Camden 4-1/2\" Push Plate Switch Wheelchair \& - CM-45/454SE1

Camden CM-45/454SE1 Push Plate Switch

Overview

The Camden CM-45/454SE1 is a 4-1/2" push plate switch designed for wheelchair-accessible door control and push-to-open applications in commercial and institutional access control environments. This device integrates network communication capability and operates on 30VDC power, making it suitable for retrofit and new installation scenarios where ADA-compliant door actuation is required. The CM-45/454SE1 (often searched as CM 45/454SE1) provides reliable credential-independent activation for facilities requiring hands-free or push-based entry mechanisms.

Key Features

• 4-1/2" Form Factor: Large, easily identifiable plate suitable for high-traffic areas and accessible entries
• Wheelchair & Push-to-Open Compatible: Meets accessibility standards for alternative actuation methods beyond traditional card readers or keypads
• TCP/IP Communication: Network-connected protocol enables remote monitoring, control, and integration with building management systems and access control platforms
• 30VDC Operating Voltage: Low-voltage operation supports standard access control power supply infrastructure and reduces installation complexity
• Lock/Strike Classification: Functions as an electrically controlled lock or strike mechanism, compatible with standard door hardware and frame mounting
• Credential-Independent Activation: Push plate operation does not require card, PIN, or biometric credential, providing universal access capability for designated entry points

Integration & Compatibility

The CM-45/454SE1 integrates into access control systems through its TCP/IP interface, allowing centralized monitoring and event logging alongside traditional credential readers and controllers. Network connectivity enables integration with software platforms that manage user access policies, audit trails, and facility-wide door control. The 30VDC requirement aligns with standard access control power supplies, simplifying wiring and reducing dedicated infrastructure needs. This device is suited for deployment in healthcare facilities, educational institutions, office buildings, and multi-tenant environments where both credentialed access and hands-free push-button egress are necessary.

The CM-45/454SE1 can be deployed as a secondary actuation method paired with primary credential readers, or as the primary access mechanism for designated accessible entries. Network connectivity allows administrators to monitor activation events, set time-based access rules, and coordinate with other networked access points in the facility.

Perspective based on aggregated and affiliated engineering team experience.

The Camden CM-45/454SE1 addresses a critical requirement in modern access control deployments: providing ADA-compliant push-button actuation without sacrificing network visibility or integration. During system planning phases, integrators often face the challenge of retrofitting accessible entry points into existing credential-based systems. This device solves that problem with a straightforward TCP/IP-connected push plate that maintains visibility alongside card readers and biometric devices.

Technical Highlights:

• Network Connectivity: TCP/IP protocol enables the CM-45/454SE1 to report activation events and receive commands from central access control software, eliminating the need for isolated relay circuits or manual monitoring
• Low-Voltage Operation: 30VDC requirement works directly with standard access control power supplies, reducing installation cost and infrastructure complexity on multi-door systems
• Accessible Design: 4-1/2" plate size and push-to-open functionality meet accessibility standards without requiring additional hardware or installation workarounds

Deployment Considerations:

• Verify network infrastructure supports TCP/IP connectivity at all installation locations; switches require dedicated CAT5e or better cabling for reliable operation
• Coordinate push plate placement with existing credential readers to avoid user confusion and ensure clear wayfinding for accessible entries
• Configure access control software to log all CM-45/454SE1 activations separately from credentialed entries for audit and compliance reporting

The CM-45/454SE1 is a practical, integration-friendly solution for facilities that require both security control and accessibility compliance. The network connectivity and 30VDC standard make it a straightforward addition to existing TCP/IP-based access control systems without special power or monitoring hardware.
