Access controller RoGer PR312EM PR312EM-G — proximity reader, single-door access control module

RoGer PR312EM PR312EM-G is a compact access controller with an integrated proximity card reader, designed to manage a single door in small commercial and residential installations. The unit reads EM-format proximity credentials and performs user authentication, door release control and basic event handling. Its design allows straightforward wiring to a door lock, an exit button and a power supply, making it suitable for straightforward access control tasks where reliable, local verification is required.

Advantages

The combined reader and controller reduces the need for separate components, simplifying installation and saving space. Built for EM proximity credentials, the device reliably recognises authorised cards and tags while providing simple user management. The PR312EM-G offers straightforward wiring for electric locks and exit buttons, and its compact form factor is suitable for mounting near entrances. The controller is suitable for installation where a single-door solution with local verification and basic event control is needed.

Suitable for

• Single-door access control in small offices and retail premises
• Residential entry points and gated communities
• Staff access management for small businesses
• Visitor access where simple credential-based entry is sufficient

Key specifications

• Built-in proximity card reader compatible with EM-format credentials
• Single-door controller with door release output
• Inputs for exit button and auxiliary sensors
• Compact enclosure suitable for surface or flush mounting
• Low-voltage operation compatible with common access control power supplies

How to use

Mount the PR312EM-G near the controlled door and connect the power supply, electric lock and exit button following the installer manual. Enrol user EM cards or tags using the built-in reader and configure access permissions according to site requirements. During normal operation, presenting a registered proximity card to the reader unlocks the door for the configured time; pressing the exit button triggers the exit input to release the lock.
