Camden CM-7024 Red LED 24V Access Control Indicator
The Camden CM-7024 is a red LED indicator light designed for 24VDC access control installations. It provides real-time visual feedback at door frames, control panels, and credential readers to signal access grants, denials, lock status, and system alerts. The unit connects directly to standard access control power and output circuits without requiring network infrastructure, specialized protocols, or external power conditioning.
Key Features
- 24VDC Operation: Rated for 24VDC supply voltage with 30VDC tolerance. Draws under 50mA—compatible with standard access control outputs without additional buffering or relays.
- Red LED Indicator: High-visibility red light for denial, alert, or fault signaling. Brightness sufficient for indoor and semi-outdoor installations.
- Wall-Mount Form Factor: Compact design for direct fastening at door frames, mullions, or control panel enclosures. Vertical or horizontal orientation.
- Passive Integration: No TCP/IP, no firmware updates, no configuration required. Energize the input terminals and the LED illuminates—operates on any 24VDC loop from your access control panel.
- Low Power Draw: Sub-50mA current consumption minimizes load on access control power supplies and output ports. Safe to parallel with other low-current signaling on the same circuit.
- 3-Year Warranty: Factory warranty covers defects in materials and workmanship across typical installation and environmental conditions.
The CM-7024 integrates into any access control architecture—traditional hardwired controllers, distributed door modules, or hybrid IP-based systems with 24VDC auxiliary outputs. It is agnostic to credential type (HID, Mifare, credential readers, or keypad logic) and requires only a spare 24VDC output or relay contact closure on the controller to function. On multi-door installations, route the indicator to the door controller's alarm or deny output terminal; on single-door systems, wire it in parallel with the strike relay or buzzer circuit.
Deployment is straightforward: identify an available 24VDC source and a spare output terminal on your access control panel, route 18-22 AWG stranded wire to the indicator location, and mount the unit where staff and visitors will notice it immediately. Typical use cases include denial indication at a vestibule (turn on the red LED when a credential is rejected), lock-open alerts during extended egress, and integration with manual request-to-exit (REX) buttons where a sustained LED signals unauthorized exit in progress. For outdoor installations or high-humidity environments (commercial kitchens, humid loading docks), pair the CM-7024 with a weatherproof polycarbonate or stainless-steel backbox to extend service life.
The CM-7024 carries a 3-year manufacturer warranty and is supported by standard access control power supplies (Altronix, Securitron, UTC) and all major door controllers (HID, Salto, Rutherford, Lenel, S2 NetBox). No special VMS integration, API calls, or network configuration is required—it is a pure hardwired indicator, making it ideal for retrofit projects, budget-constrained installations, or environments where IP wiring is not yet deployed.

We've deployed hundreds of 24VDC LED indicators across access control installations—from small medical clinics to multi-building corporate campuses—and the CM-7024 represents the gold standard for simplicity and reliability. The appeal is immediate: it requires zero integration overhead, zero programming, and zero troubleshooting beyond a multimeter to confirm 24V is present at the terminals. In our experience, the biggest operational win is reducing user confusion during access denial. A red LED that lights immediately on card rejection cuts support calls and prevents tailgating behavior at high-traffic entry points. The sub-50mA draw is critical on legacy installations where access control power supplies are already fully loaded; we've seen projects abandoned because a higher-current indicator would have required a separate 24VDC auxiliary supply. The CM-7024 eliminates that capex burden. On the flip side, this is a passive indicator—there's no dimming, no programmable color cycling, and no remote status feedback to your VMS or NVR. If you need graduated alerting (yellow for warning, red for lockdown) or bidirectional signaling to confirm the LED is actually functioning, you'll need a network-addressable indicator and a compatible 24V IP relay gateway. For straightforward deny/permit feedback at a single door or cluster of doors, the CM-7024 is unbeatable in terms of cost, installation speed, and mean time to repair.
Technical Highlights:
- 24VDC with 30VDC tolerance: Most access control power supplies run between 24V and 27.6V nominal under load—the 30V ceiling ensures the LED will illuminate reliably even with voltage sag on older transformer-based supplies or long wire runs. No need to adjust trim pots or recondition the supply voltage.
- Sub-50mA draw: Hardwired access control outputs on legacy panels (HID VertX, Salto KM, Rutherford models pre-2015) are often rated 100–200mA maximum per port. Pairing the CM-7024 with a buzzer and a strike relay on the same output is safe; the indicator becomes invisible to the power budget.
- Passive indication (no feedback loop): Unlike networked indicators, the CM-7024 doesn't report back whether the LED is burnt out or the wire is cut. Monitor indicator health via scheduled site visits or pair it with a separate circuit-integrity test relay if critical alerting is required.
- Red-only option: Camden does not produce a separate green version of this model. For multi-state indication (permit/deny), integrate red for deny and use a separate green indicator or rely on the door strike buzzer for permit feedback.
Deployment Considerations:
- Confirm your access control panel has a spare 24VDC output terminal before ordering. If the panel is fully loaded (all outputs driving strikes, electrified locks, and buzzers), you'll need a dedicated 24VDC auxiliary supply or relay module to drive the indicator.
- Route indicator wiring in the same conduit or tray as access control power and output circuits; do not mix with low-voltage audio or data lines to avoid inductive coupling and false triggering.
- For outdoor installations (canopy entry points, parking garage booths), use a sealed polycarbonate or painted-steel backbox to shield the LED from direct rain and UV. The indicator itself is not NEMA-rated and will degrade in unprotected outdoor conditions within 12–18 months.
- On systems with multiple doors and a single access control processor, use the controller's zone or door output to route denial indication to the correct indicator—do not wire all indicators in parallel to the same deny output, or every door will flash on a single rejection event elsewhere in the system.
The CM-7024 is the right choice for access control integrators and end-users who prioritize operational simplicity and lowest total cost of ownership on fixed-budget retrofit or new build projects. It is equally at home in a 5-door office installation and a 50-door enterprise—the only variable is installation time.
