Controller for access control of entrance doors in residential, administrative and manufacturing buildings - "DACC-1 USB"

"DACC-1 USB" is controller for restricting of access to entrance doors in residential, administrative and manufacturing buildings.

Identification is performed with contactless RFID chip-cards and keyfobs. The controller allows adding of:

• 999 work cards – for residents/workers in the building
• 50 service cards – for service personnel (postmen, personnel of communal services, etc.)
• 16 system cards – for access to system functions without the need of PC

The device can control electromechanical locks by supplying/interrupting current supply to the lock, with adjustable current level.

Controller for access control of elevators in residential and administrative buildings - "DACC-1 USB"

"DACC-1 USB" is controller for restricting of access to elevators in residential and administrative buildings.

Identification is performed with contactless RFID chip-cards and keyfobs. The controller allows adding of:

• 999 work cards – for residents/workers in the building
• 50 service cards – for service personnel (eg. personnel of communal services)
• 16 system cards – for access to system functions without the need of PC

Controller outputs for elevator:

• Normally closed relay for panel with elevator buttons.
• Integrated impulse power supply from 18 to 72V, with galvanic isolation.
• Integrated linear power supply from 7.5 to 18V.

The controller activates the elevator buttons only after a valid card is put in front of the reader. Each card has a counter, which allows individual monitoring of elevator usage.
