Description

Codelocks A3 Dual Standalone Door Controller with RFID

A3 Door Controllers- from Access by Codelocks. Compact, standalone programmable door controllers with RFID functionality. Featuring three models, each bringing unique qualities to the range, the A3 door controllers provide a compact, affordable proximity access control system allowing flexible entry for up to 1000 users.
The A3 Dual MIFARE® compatible door controller provides a compact, affordable proximity access control system allowing flexible entry for up to 600 users, including two Panic Clients.
Many smaller business buildings are still secured by traditional lock and key, meaning doors can be left unlocked all day leaving them open to possibilities of unauthorized persons gaining access, as well as keys going missing. The A3 Dual door controller offers you a keyless solution as a standalone product; an affordable access control system that does not require complex software purchases, external programmers or licensing costs.
