Standalone 4000-user Access Keypad

This RFID/EM keypad provides offline door control for up to 4000 users. It operates on a DC 12 V supply drawing 0.1 A when the lock releases. The unit accepts EM, ID and IC cards at 125 kHz and 13.56 MHz frequencies. Master cards, PIN codes or combined card-plus-PIN entry are all supported.

Continuous Operation on 12 V Supply

The controller is designed for permanent installation and retains all user data during power loss. With an inductive read range of 5 to 15 mm, credentials are read quickly at the door. Current draw remains low at 0.1 A only during the unlock pulse, so the 12 V source is not heavily loaded. No network connection is required for daily operation.

Metal Housing With Wired or Wireless Bell Link

The metal enclosure measures 120 by 78 by 22 mm and weighs 0.22 kg. Mounting screws are supplied for direct surface fitting. A door-bell interface can be wired or configured wirelessly according to the installer's choice. Ten RFID key tabs and an English manual complete the package for immediate setup.

Questions about this item

How much power does the 12 V DC supply need to deliver for the lock to run all day?

The unit draws 0.1 A at 12 V DC, so the supply must provide at least that current continuously.

What extra hardware must I already have for the keypad to open a door?

You need a 12 V DC power source and an electric strike or magnetic lock wired to the relay output.

Will the 125 kHz reader work with the EM cards I already use on an older panel?

Yes, the reader accepts EM cards at 125 kHz alongside ID and IC types at 13.56 MHz.
