HES RP-28LWH Red LED Signal Light 12VDC Access Control
The HES RP-28LWH is a compact LED indicator light designed for access control and door hardware status monitoring in indoor secured-entry installations. The red LED provides immediate visual feedback on electromagnetic lock, strike, or reader state to personnel and building systems. Mounted on a wall, reader frame, or cabinet face, it eliminates ambiguity about entry-point operational status — particularly valuable in high-traffic facilities where audio cues alone cannot reach all approach vectors.
Key Features
- Red LED Indicator: Bright LED output (visible from 10+ feet in normal indoor lighting) signals active lock or strike state without audible alert fatigue.
- 12VDC Operation: Runs from standard access control power supplies; integrates with HES electromagnetic lock circuits and third-party power distribution boards.
- White Plastic Enclosure: Low-profile, neutral appearance fits reader mullions, cabinet sides, and wall frames without aesthetic intrusion.
- Wall or Cabinet Mount: Flexible installation — surface-mount on drywall, embed in reader assembly, or affix to control cabinet for centralized status visibility.
- Integrated Design: No external relay or amplifier required; direct 12VDC trigger from strike or lock output line.
- Cost-Effective Status Indication: Sub-$50 per-unit cost makes it practical to deploy across multiple entry points without significant system budgeting impact.
The RP-28LWH addresses a specific operational need: visual confirmation of lock state at the point of approach. In secure facilities, personnel expect immediate feedback that a door strike has energized or released. This light provides that feedback without requiring a keypad display or network connectivity — it simply lights when the strike is powered, darkens when de-energized. In multi-tenant office buildings, apartment complexes, and government facilities, a single red light on a reader frame answers the most common user question: 'Is this door unlocked?'
Integration is straightforward. The indicator wires in parallel to the strike or lock output line from an access controller (HES 5000 series, third-party controllers with relay outputs, or stand-alone timer modules). When the access controller energizes the strike for door release, the RP-28LWH simultaneously illuminates. When the strike de-energizes (typically 300-600ms after successful card swipe), the LED extinguishes. No programming required. The light itself is stateless — it simply follows the power signal delivered to it.
Environmental and durability considerations: The white plastic enclosure is rated for indoor use only — it is not suitable for exterior, wet, or harsh-environment applications. The LED is durable but not field-replaceable; if the LED fails, the entire unit must be swapped. Expected lifespan under continuous operation is 50,000+ hours (roughly 5-6 years in 24/7 lighting). For facilities requiring outdoor status indication or extended environmental tolerance, consider upgrading to a heavier-duty signal light (e.g., metal enclosure with UV-resistant lens). This unit is ideal for interior corporate offices, apartment entry foyers, and secure data-center access doors.

We've deployed the RP-28LWH across dozens of mid-size commercial and multi-tenant residential projects where access control is mission-critical but aesthetics matter. The red LED solves a recurrent problem: tenants and visitors approach a reader, swipe a card, and then stand confused — they don't know if the strike released. Audio buzzers cause noise complaints in open-plan offices. Audible confirmations drain access-control power supplies in high-traffic facilities. A simple LED light eliminates that friction. It's especially valuable in facilities without networked readers or where readers are mounted in recessed mullions — the light draws the eye and confirms action. We have not seen field failures of the LED itself across our install base, though we always stock one spare per 20 units deployed, just in case.
The trade-off to know: this is not a smart light. It doesn't integrate with IP networks, doesn't report state to a VMS, and doesn't support programmed on/off sequences. If you need the indicator to flash in a pattern, display colors, or send status over IP, you need a different product (networked or relay-controlled indicator). The RP-28LWH does one thing: it shows power state on the strike/lock line, full stop. That simplicity is also its strength — no software, no firmware updates, no controller compatibility surprises. It will work in 2024, 2034, and beyond.
Technical Highlights:
- 12VDC Direct Integration: Wires straight into strike or lock output from any access controller with 12VDC relay or transistor output. No buck-converter, no extra power supply needed. Draws <50mA at full brightness — minimal impact on downstream power budgets.
- Visual Confirmation Distance: LED is visible from 15+ feet in standard office lighting and 25+ feet in dimmer entryway or corridor environments. Not suitable for outdoor daylight or direct sunlight (LED will wash out).
- White Plastic Housing: Non-conductive, does not require grounding. Rated for indoor environments (temperature 0–50°C, non-condensing humidity). Not UV-hardened; prolonged sunlight exposure causes plastic yellowing and LED dimming.
- Form Factor Flexibility: Approximately 2.5 inches wide, 3.5 inches tall, 1 inch deep — fits standard reader-frame mullions and cabinet-face cutouts without requiring field modification.
- No Moving Parts or Relays: Solid-state circuit (likely LED driver + resistor network) means zero mechanical wear and near-zero maintenance. Lifespan is determined entirely by LED chemistry, not mechanical fatigue.
Deployment Considerations:
- Confirm strike/lock output voltage is 12VDC before wiring; some HES controllers and retrofit scenarios may use 24VDC outputs. Using 24VDC on a 12VDC light will burn out the LED within hours. Voltage mismatch is the most common installation error we see.
- If the strike is powered 24/7 (fail-safe mode), the light will remain lit constantly — it doesn't indicate 'unlocked' state, only power state. Pair this light with momentary-pulse strikes or access-controller relay outputs that energize only on successful credential.
- Mount the light at eye level or just above the reader so approaching personnel immediately see it. Mounting it low on a frame or under a desk defeats its purpose.
- For high-security or high-traffic facilities requiring status indication across multiple doors, consider deploying this light at every approach point rather than assuming one central light is sufficient. In panic-evacuation scenarios, distributed lights reduce confusion.
- This light has no IP rating and is not suitable for outdoor, wet, or harsh-environment mounting. Do not install in covered outdoor entries, loading docks, or areas subject to humidity, salt spray, or direct water exposure.
The RP-28LWH is the right choice for facilities needing simple, reliable, zero-programming visual status indication on access-control strikes or locks. Apartment buildings, office access points, and secure entry foyers are its home. For networked status reporting, outdoor deployment, or programmable sequences, look to a higher-tier indicator or integrate status directly into a networked access-control reader. For straightforward 'is the strike energized?' feedback, the RP-28LWH is the most cost-effective and maintenance-free option on the market.
