HES DK-26PSS Digital Keypad Narrow Stainless Steel
Overview
The HES DK-26PSS is a narrow-profile digital keypad engineered for access control deployments where space and environmental durability matter. Built from stainless steel, this compact keypad delivers corrosion resistance essential for coastal, high-moisture, or chemically treated installations—environments where standard painted steel or plastic keypads degrade quickly. The narrow form factor solves a real integration problem: retrofit projects and space-constrained door frames where traditional keypads simply don't fit. If you're upgrading legacy access control infrastructure or installing in tight architectural spaces, the DK-26PSS eliminates the need for relocating frame work or custom enclosures.
Voltage flexibility is built in. The DK-26PSS operates on both 12VDC and 24VDC control circuits, matching the standard power rails found in contemporary access control panels and legacy installations alike. This dual-voltage support reduces the risk of incompatibility during system integration and simplifies logistics—you stock fewer SKUs across multi-site deployments. The keypad integrates with access control systems using standard digital keypad protocols, ensuring compatibility with HES platforms and third-party controllers that recognize common entry device standards.
Key Features
- Narrow-Profile Form Factor: Compact design slides into restricted mounting spaces where standard keypads fail, eliminating custom frame modifications and reducing installation labor on retrofit projects.
- Stainless Steel Construction: Resists rust, salt spray, and oxidation. Meaningful in coastal, high-humidity, or chemically treated environments where painted steel or plastic housings corrode or degrade within 2–3 years. Stainless maintains finish integrity for 10+ years in harsh conditions.
- 12VDC and 24VDC Compatibility: Operates on both standard control voltages found in contemporary and legacy access panels, reducing the need for voltage converters or system redesign during upgrades.
- Standard Digital Keypad Protocols: Integrates with HES systems and third-party controllers using industry-standard entry device signaling, avoiding proprietary lock-in and supporting mixed-vendor deployments.
- Suitable for Commercial, Institutional, and Industrial Deployments: Rated and proven for office buildings, educational campuses, manufacturing plants, warehouses, and utility facilities where durability and code compliance are non-negotiable.
- Mounting Hardware Included: Reduces project-start friction by eliminating the need to source fasteners separately; installation documentation supports on-site commissioning.
Integration & Compatibility
The DK-26PSS pairs directly with HES access control platforms and integrates into any control system accepting standard digital keypad inputs. Its 12VDC/24VDC dual-voltage design means no power supply conversion or additional hardware required—connect directly to your panel's standard reader or door control circuit. On retrofit projects where a keypad needs to replace a worn unit in a tight opening, the narrow profile eliminates frame rework that would otherwise add weeks and cost to the schedule.
Typical Applications
Deploy the DK-26PSS at personnel entry points, gate access stations, and secured zone authentication in commercial offices, educational institutions, industrial plants, and utility facilities. The narrow design excels in retrofit scenarios where space constraints would otherwise force costly door-frame modifications. Outdoor mounting (loading docks, exterior gates, coastal facilities) leverages the stainless steel corrosion resistance to avoid premature housing failure.

Frequently Asked Questions
Q: Can the DK-26PSS be used in outdoor installations?
A: Yes. The stainless steel housing resists rust, salt spray, and oxidation, making it suitable for outdoor door frames, gate access systems, and exposed mounting locations. However, pair it with a weather-resistant enclosure or overhang to prevent direct rain from entering the keypad face.
Q: What voltages does the DK-26PSS support?
A: The keypad operates on both 12VDC and 24VDC control circuits, eliminating the need for voltage conversion and simplifying integration into existing access control panels.
Q: Is the DK-26PSS compatible with third-party access control systems?
A: Yes. The DK-26PSS uses standard digital keypad protocols, making it compatible with HES access control systems and third-party platforms that support conventional entry device signaling.
Q: What makes the narrow profile valuable for my installation?
A: The narrow design fits into space-constrained door frames and architectural openings where traditional keypads cannot mount without custom frame modifications. This is especially valuable on retrofit projects where you want to avoid costly structural work.
Q: Is stainless steel housing necessary for my deployment?
A: If your installation is indoors with stable humidity and no corrosive atmospheres, standard painted steel is adequate. Choose stainless if you're deploying in coastal areas, high-moisture environments, chemical facilities, or any location where salt spray or oxidation poses a risk within a 5–10 year horizon.

The DK-26PSS solves a specific integration headache: retrofit access control upgrades in tight spaces. I've seen projects stall because a replacement keypad doesn't fit the existing door frame without frame rework—that's where the narrow profile of the DK-26PSS earns its place. Pair the 12VDC/24VDC dual-voltage design with standard protocol support, and you get a keypad that drops into most contemporary or legacy control systems without voltage conversion hardware or protocol translation.
Technical Highlights:
- Narrow-Profile Form Factor: Eliminates custom frame modifications on retrofit projects, cutting installation labor and schedule risk when upgrading legacy access control infrastructure.
- Stainless Steel Housing: Resists corrosion, salt spray, and oxidation. In coastal or high-humidity environments, this translates to 10+ years of service versus 2–3 years for painted steel housings—a genuine cost-per-year-of-service advantage.
- Dual 12/24VDC Support: Removes voltage conversion requirements and matches standard control panel outputs, simplifying procurement and reducing BOM complexity across multi-site deployments.
Deployment Considerations:
- On outdoor installations, pair the keypad with a weather-resistant overhang or enclosure—stainless steel resists rust, but direct rain into the key switch contacts accelerates wear. This is especially critical in coastal environments where salt spray is constant.
- If you're integrating into a legacy HES system, verify that your control panel firmware supports the DK-26PSS protocol version before ordering—this is a quick call to your integrator, but worth confirming upfront to avoid surprises during commissioning.
The DK-26PSS is your go-to keypad for retrofit scenarios where space is the constraint and corrosion resistance is a requirement. Commercial retrofits, industrial gate access, and coastal facility upgrades are where this unit earns its cost.
