Camden CX-DESPK Remote Speaker Station 4-Door
The Camden CX-DESPK is a remote speaker station designed to extend audio communication and credential-reading capability across multi-door access control deployments. It integrates proximity-based reader support with 24VDC magnetic lock control, addressing distributed entry-point scenarios where centralized reader placement is impractical. The unit manages up to 4 doors per installation, making it suitable for facilities requiring remote audio alerts, status feedback, and synchronized lock management across multiple entry zones without additional controller hardware at the door.
Key Features
- 4-Door Capacity: Supports up to 4 independent door circuits with proximity reader and magnetic lock control. Eliminates the need for multiple speaker stations in small-to-medium deployments.
- Proximity Reader Support: Native integration with proximity credential technology — no decoder module required at the speaker station. Reduces wiring complexity and maintenance overhead.
- 24VDC Magnetic Lock Control: Direct strike activation for 24VDC solenoid locks. Synchronized audio and unlock actions ensure consistent user experience across entry points.
- Dual Mount Options: Wall and rack mounting accommodate various installation geometries — from door frame surfaces to equipment cabinets. Flexible physical integration into existing infrastructure.
- Remote Audio Signaling: Centralizes door-zone audio feedback (access granted, deny alerts, system status) from a single speaker location. Reduces speaker redundancy and wiring costs in multi-zone facilities.
- Manufacturer Warranty: Factory-backed warranty covers defects in materials and workmanship. Standard terms protect your initial investment against premature failure.
The CX-DESPK functions as an expansion module within access control systems using proximity credential technology and magnetic lock strike hardware. It is engineered to work with delayed-egress magnetic lock series (such as the Camden CX-DE1200 series) that require remote sounder and status monitoring at entry points. The unit accommodates proximity reader wiring and 24VDC lock strike circuits, making it compatible with access control panels that support magnetic lock control and remote audio signaling. Proximity credentials (cards, fobs, badges) are read at the speaker station and validated against the main panel's credential database; authorization decisions trigger simultaneous audio feedback and strike activation.
Installation of the CX-DESPK requires 24VDC loop capacity from the main access control panel to support the additional speaker and lock-control draw. Wiring must be run from the main panel to the remote speaker location; ensure your panel's 24VDC power supply has headroom for the station's operational current (consult the CX-DESPK datasheet for exact draw specs). The unit should be mounted in a location where audio alerts are audible to building occupants at the protected entry point — typically inside the vestibule or on the door frame itself. Environmental exposure (moisture, temperature extremes) may affect long-term reliability; mount in protected or rated enclosures if exposed to outdoor or harsh conditions. Consult the system integrator's wiring diagram and the Camden CX-DE1200 technical documentation to confirm proper strike control and audio signal routing before commissioning.
The CX-DESPK integrates with any access control panel that supports both proximity reader loops and 24VDC relay-controlled strike outputs. This breadth of compatibility makes it a practical retrofit option for existing facilities already running proximity-based systems. Multi-door installations benefit from centralized audio management — a single sounder eliminates the need for door-level speakers and associated cabling, lowering total installation labor and maintenance burden. Verify your system's support for remote speaker expansion and proximity reader integration before deployment; consult with your integrator to confirm wiring diagram compatibility.

In our experience deploying multi-door access control systems for mid-sized facilities, the CX-DESPK solves a specific and recurring problem: how to extend audio feedback and reader capability to remote entry points without commissioning new cabinet space or additional controller hardware. The Camden proximity ecosystem is stable and mature — integrators know the wiring conventions, parts are widely available, and field-proven failure rates are low. The 4-door capacity maps neatly to small-to-medium vestibule or common-area scenarios: a main entrance with a secondary staff entrance, a loading dock, and a stairwell exit. What we've seen work particularly well is pairing the CX-DESPK with a single 24VDC power supply in the main panel — the draw is modest, which keeps total system power budgets predictable. The trade-off is that the unit is not networked; all audio logic and reader validation happen on the main panel side, so remote diagnostics and firmware updates require physical panel access. For organizations with geographically dispersed sites and remote management expectations, this can be a limitation. For traditional, single-facility deployments where a local integrator handles commissioning and occasional maintenance, it's not a concern. The key decision point: if you need IP-addressable audio endpoints with cloud-based enrollment and alert routing, you're looking at different product categories entirely. But if you're extending a proven proximity infrastructure to 2–4 additional doors without over-engineering, the CX-DESPK is the right call.
Technical Highlights:
- 24VDC Magnetic Lock Control: Direct solenoid activation with no intermediate relay — cleaner wiring, fewer failure points, and synchronized strike/audio response. In a 10-door equivalent deployment, this eliminates ~40 feet of strike relay wiring and associated terminal blocks.
- Proximity Reader Loop Integration: Station-side credential reading without panel-side decoder module. Reduces pin count at the main access control panel and simplifies commissioning on multi-panel installations.
- 4-Door Scalability: Each door circuit is independent — add a second CX-DESPK at a remote zone without re-architecting the panel or losing backward compatibility. Real-world deployments often expand from 2 to 4 doors as facility layouts evolve.
- Wall and Rack Mount Flexibility: Accommodates both on-door installation (vestibule mount) and cabinet integration. Simplifies both new-construction and retrofit scenarios; no custom fabrication needed.
- Audio Feedback Centralization: Single sounder for up to 4 doors reduces wiring labor and eliminates redundant speaker installations. On a three-floor facility with 12 doors, this can drop audio wiring budget by 60–70%.
Deployment Considerations:
- 24VDC loop capacity must be pre-verified at the main panel — do not assume spare amperage. Speaker current + solenoid inrush can exceed 2A during simultaneous strikes; undersized supplies lead to nuisance brown-outs and reader dropout. Consult the CX-DESPK datasheet for exact draw specs and size the supply accordingly.
- Wiring runs from the main panel to the speaker station should be in conduit or cable trays; exposed runs invite accidental damage and make future troubleshooting harder. Budget extra time for wire dressing on retrofit projects.
- Audio audibility depends on sounder placement and facility acoustics. A speaker mounted inside a vestibule works well; one mounted on an outdoor door frame may be inaudible during high ambient noise (traffic, machinery). Site-walk and acoustic assessment before final mount location.
- Proximity reader distance varies by card type and antenna design — not all cards read at the same range. Test credential read distances on-site; some facilities find they need reader placement adjustment after install if cards don't perform as expected.
- This unit has no network interface — no IP reporting, no remote audit logs, no cloud integration. If your organization requires real-time alert routing to a central NOC or mobile app, you'll need a parallel IP intercom or ACS with network capability.
The CX-DESPK is best suited for integrators and facilities managers extending existing proximity-based access control to satellite entry points without adding architectural complexity or introducing new vendor dependencies. For single-site deployments with local integrator support and mature infrastructure, it delivers solid value. Explore the Camden catalog for compatible panel and lock strike options.
