ASEC Internal Surface Proximity Keypad

The Asec Internal Surface Proximity Keypad (AS11891) is a versatile and robust access control solution designed for surface-mounted internal installations. Featuring a durable zinc alloy electroplated casing, this keypad combines a traditional 12-button PIN entry system with an integrated proximity reader compatible with EM cards and fobs. This dual-method entry provides flexible security options for up to 500 users.

Engineered with PCB conformal coated components, the keypad is highly reliable. While designed primarily for internal use, it can be adapted for external applications when fitted with the Asec Rainshield (AS11892, available separately). It features adjustable output timers on both Lock and Aux outputs, an input for a separate Wiegand reader, and optional backlighting for low-light visibility. The unit is supplied complete with a security screw for enhanced tamper resistance.
