Access control proximity reader with keypad Atlo ATLO-KR-522

The Atlo ATLO-KR-522 is a proximity access control reader with an integrated keypad designed for secure user authentication and door entry management. The device reads contactless credentials and allows PIN entry on a built-in numeric keypad, enabling single- or two-factor verification. Its compact housing and wall-mount form factor make it suitable for installation at entrances to offices, controlled areas and service rooms where reliable credential reading and PIN-based access control are required.

Advantages

The reader combines RFID proximity detection with a tactile keypad to support flexible authentication modes without additional hardware. It provides fast credential recognition and responsive keypad input for smooth access workflows. The device's construction is intended for permanent installation and straightforward wiring to common access control panels. Low-profile design and neutral styling support integration with a variety of interior and exterior entry points.

Suitable for

• Office main and secondary entrances
• Restricted areas and server rooms
• Shared facilities with controlled access (storage, archives)
• Reception areas requiring staff and visitor differentiation
• Upgrade projects adding PIN-backed two-factor authentication

Key specifications

• Authentication methods: proximity (contactless credential) and PIN keypad
• Keypad: integrated numeric keypad for PIN entry
• Mounting: wall-mounted reader housing suitable for indoor and sheltered outdoor use
• Interface: standard access-control wiring compatible with common control panels (power, data lines)
• Construction: compact, tamper-resistant enclosure designed for fixed installation
• Operation: rapid credential detection and immediate keypad response for access decisions

How to use

Install the reader at a convenient height next to the secured door and connect power and data cables to the access control panel following the panel manufacturer's wiring diagram. Present an authorized contactless credential near the reader surface to perform identification; when PIN verification is required, enter the assigned numeric code on the integrated keypad and confirm per system configuration. The access control system will evaluate credential and PIN according to configured rules and activate the door release mechanism or deny access.

Usage recommendations

Position the reader in a sheltered location to reduce exposure to direct weather and ensure reliable credential reading. For two-factor security, enforce PIN policies such as minimum length and periodic changes through the access control system. Regularly check wiring connections and clean the reader surface with a soft, non-abrasive cloth to maintain sensor performance.
