Pengenalan Produk

A dedicated microcontroller supervises two monitored doors and their request inputs. The board uses separate relay contacts for door release, busy indication and alarm signalling, and can be installed in a tamper-switched steel enclosure. Configuration jumpers determine the idle behaviour. The assembled two-door system suits a local airlock where operation should remain independent of Ethernet, while still giving the installer clear connection points for locks and auxiliary indications.
