GEM DG-25LD: Stainless Steel Digital Keypad for Single Door Access Control

Key Features Of The GEM DG-25LD:

• Standalone Access Control: The GEM DG-25LD functions as a complete access control solution for a single door, eliminating the need for an external control panel.
• High User Capacity: Supports up to 200 regular PINs and an additional 10 temporary PINs, ideal for managing a large number of users.
• Durable Stainless Steel Casing: Provides exceptional resistance to wear, corrosion, and vandalism, ensuring long-term performance.
• Vandal Resistant Screws: Enhances security by deterring unauthorized removal or tampering.
• Dual Relays Output: Equipped with two independent relays (NC/COM/COM, 3A/24VDC), allowing for multi-control applications such as controlling a main door lock and a secondary device (e.g., gate, alarm, or lighting).
• Door Reed Switch Input for Anti-Tailgating: Integrates with a door sensor to detect when the door is open, which can be used to prevent tailgating by requiring a second entry after the door closes.
• Fully Programmable via Keypad: All  of the GEM DG-25LD functions and settings can be easily configured directly through the keypad using a master code.
• 3 LED Display with Audible Indication: Provides clear visual (LEDs) and audible (buzzer) feedback for status, programming, and access events.
• Invalid PIN Lock-Out: Enhances security by temporarily locking out the keypad after multiple incorrect PIN attempts, deterring brute-force attacks.
• Non-Volatile Memory: Ensures that all programmed PINs and settings are retained even in the event of a power loss.
• REX Input (Request to Exit): Allows for connection of an exit button or sensor for free egress from the secure side.
