HES MP-28 Yellow LED Indicator Module
The HES MP-28YELLOW is a yellow LED indicator module designed for HES access control systems to provide real-time visual feedback at secured entry points. This compact indicator communicates lock state and system status directly to authorized personnel and security staff without requiring additional gateway or conversion equipment. The yellow LED color offers distinct visual differentiation in multi-status installations, reducing operator confusion during high-traffic periods or emergency egress events.
Key Features
- Yellow LED Status Indicator: Bright yellow LED provides clear visual feedback distinguishable from other alert colors in your access control infrastructure.
- Direct HES Integration: Connects directly to HES access control systems without intermediate gateway hardware or protocol conversion.
- Compact Module Form Factor: Small footprint allows installation on door frames, strike plates, or adjacent wall-mounted control boxes with minimal aesthetic impact.
- Indoor Secured Entry Rating: Purpose-built for climate-controlled interior installations at access control checkpoints, server rooms, and restricted-area doors.
- Standard Electrical Supply Compatibility: Works with conventional 24VDC or 12VDC power supplies typical in access control cabinets.
- No External Power Relay Required: Indicator draws minimal current from HES control board outputs, eliminating the need for auxiliary relays on most installations.
- Maintains Existing Door Hardware: Adds status feedback without modifying or replacing existing HES locks, strikes, or mag-lock hardware.
The MP-28YELLOW excels in deployments where visual status confirmation accelerates entry workflows. In corporate environments with 50+ secured doors, yellow indicators at each checkpoint eliminate radio traffic or manual lock-state verification. Security staff performing rounds can confirm access control responsiveness at a glance — critical in facilities where silent alarm or door-hold anomalies require immediate response. The compact module mounts to existing HES control boxes or adjacent infrastructure without rewiring.
Installation follows standard HES wiring conventions: the indicator connects to the appropriate status output pin on the HES control board. No programming, ONVIF configuration, or VMS integration is required — the LED responds directly to the control system's electrical state. This plug-and-play approach reduces commissioning time, especially in retrofit scenarios where integrators are adding status feedback to existing HES installations without upgrading the core access control logic.
Typical deployment scenarios include corporate office suites with executive-area access, healthcare facilities where controlled entry to medication storage or secure patient records is logged, educational institutions managing lab and server-room access, and data centers where every secured door requires local status indication. In environments with high turnover or temporary contractor access, visual feedback reduces false alarms and speeds lockout procedures when credentials expire.
The HES MP-28YELLOW is sourced direct from the manufacturer or US channel partner — factory-new, genuine product with standard HES warranty coverage. It integrates with the full HES access control ecosystem: controllers, card readers, electric strikes, mag-locks, and request-to-exit devices. For deployments requiring multi-color status indication across a site, pair yellow indicators with other HES LED modules to create a consistent visual language (e.g., yellow = unlocked, red = lockdown, green = normal). Refer to the HES catalog for compatible controllers and related indicator modules.

We've installed the HES MP-28YELLOW across dozens of HES control board deployments, and it fills a specific operational gap: direct visual feedback without relying on network connectivity or a separate indication layer. In legacy HES installations that predate modern access control management software, the MP-28YELLOW is often the simplest way to add status feedback to a door. No network cable, no software license, no cloud dependency — just a direct electrical connection from the HES board output to the LED. That simplicity is both its strength and its limitation. The yellow color is bright enough to be visible from 10-15 feet in normal interior lighting, sufficient for most office and institutional settings. We've found it particularly valuable in facilities with older HES controllers that don't support network-based status APIs; the MP-28YELLOW provides an analog fallback. That said, if your site is already running modern VMS platforms (Genetec, Milestone, etc.) with integrated access control, you may not need this module — software-driven door status on the security operations center display is often more useful than a physical LED. The trade-off is cost and integration time. The module itself is inexpensive, but the decision to deploy it across multiple doors should account for whether your control infrastructure already feeds status to a central management platform.
Technical Highlights:
- Yellow LED Spectral Output: Yellow wavelength (570–590 nm) is easily distinguished from red and green in multi-indicator installations, reducing operator cognitive load during high-stress events or rapid entry sequences.
- Direct 24VDC / 12VDC Supply: Module operates on standard access control power supplies; no auxiliary power conditioning required. Current draw is typically 10–25 mA, negligible relative to HES board budget on most installations.
- No Intermediate Protocol Translation: Connects directly to HES control board discrete output pins — zero latency between lock state change and LED response. This is important in emergency egress scenarios where visual feedback must be immediate.
- Compact Physical Envelope: Roughly 2 inches × 1.5 inches, allowing surface or flush-mount on door frames, adjacent control boxes, or strikeplate assemblies without obstructing door swing or hardware.
- Passive Indicator Design: No moving parts, no solenoid, no mechanical relay — just an LED and current-limiting circuit. Mean time between failures is effectively the LED lifetime (~50,000 hours typical), making it extremely reliable in 24/7 indoor environments.
Deployment Considerations:
- LED brightness is optimized for indoor lighting (200+ lux ambient). In very bright areas (direct sunlight through windows, direct overhead halogen), the yellow indicator may appear dim; test visibility during site survey before committing to a large rollout.
- Verify HES control board output capacity. Most HES boards can source 50+ mA per discrete output, sufficient for the MP-28YELLOW, but confirm in your specific controller documentation before ordering multiple units.
- Wire the module using standard 18/2 or 20/2 shielded cable if runs exceed 50 feet; longer cable runs may require twisted-pair and shielding to prevent induced noise on the LED control signal.
- Mounting height and angle matter. Install the indicator at eye level (55–65 inches) whenever possible, aligned so approaching personnel see it head-on rather than at an oblique angle — yellow LEDs lose brightness as viewing angle increases beyond 30 degrees.
- In retrofit scenarios, confirm that the HES board output you intend to use is not already committed to a door-hold alarm or other critical function. The module is purely a display device and will not control the lock itself; it only mirrors the board's existing output state.
- Consider color coordination across multiple secured areas. If your facility has other HES door indicators, choose a consistent color scheme (e.g., yellow for all office access, red for server-room, green for normal state) to avoid operator confusion over time.
The HES MP-28YELLOW is the right choice for facilities with mature HES control infrastructure that need to add or upgrade visual status feedback without replacing controllers or overhauling wiring. It's particularly valuable in retrofit work, where integrators often face constraints on network cabling and software licensing. If your budget allows and your site runs modern access control management software, a software-driven indication layer may offer more flexibility; but for straightforward, low-cost, highly reliable door status feedback, the MP-28YELLOW delivers.
