Alarm Controls KP-400 Weatherproof Vandalproof Digital Keypad - Dual

In this review of the Alarm Controls KP-400 the focus is on reliable outdoor access control for commercial and exterior residential installations. The bottom line: this weatherproof, vandalproof digital keypad with a metal back box and dual relay outputs is for installers and property managers who need a robust, tamper-resistant entry interface that keeps working in exposed locations. Our review finds it straightforward to wire into common access systems and tough enough for gates and exterior doors where durability and predictable relay behavior matter most.

Key Features

• Weatherproof construction: The sealed housing and metal back box protect electronics from rain and moisture so the keypad can be installed outdoors without special enclosures.
• Vandalproof design: The metal back box and solid front reduce the risk of tampering or forced removal, helping prolong service life on exposed gates and doors.
• Dual relay outputs: Two relay contacts provide flexibility for controlling a strike and an alarm output or separating lock and auxiliary functions on a single unit.
• Digital keypad interface: The familiar push-button keypad offers simple PIN entry for users and straightforward programming for administrators during installation.
• Accessory friendly: As a purpose-built keypad accessory it integrates with common access control systems to add secure keypad entry without major system changes.

Who It's For

The KP-400 is aimed at professional installers, building maintenance teams, and property managers who need a durable keypad for outdoor gates, loading docks, and perimeter doors. It suits locations where moisture, wind, and casual vandalism are real concerns and where a keyed or card reader is not required.

Customers who need wireless entry, touchscreen interfaces, or integrated card readers should look elsewhere; this keypad is a straightforward wired digital unit focused on ruggedness and relay flexibility rather than advanced user interface features or networked management.
