Installation Instructions ACC 50
Handling ID cards
The cards are recognized reliably and clearly on the condition that the distance to the ACC 50 is not
exceeded. The receiver unit of the ACC 50 is in the upper third. The optimum card distance is 5-10
cm, the card, however, should be held, if possible, parallel to the device. In order to ensure that the
card is read reliably, just pass the card in front of the ACC 50.
Principle of contactless cards:
The inside of the card comprises an oscillating circuit and a micro chip which bears the stored code
of the card. The ACC 50 radiates a weak electromagnetic field which is in resonance with the
oscillating circuit of the card. The card modulates the received frequency with its binary pattern,
which is received by the ACC 50.
All contactless cards offered by our comany are unique. Every existing card contains different data
Programming card set
The programming card set comprises 3 cards:
The actual mode of the ACC 50 can be switched to using these cards . The programming card
set is programmed by the installer (see "Creating the programming card set").
The ACC 50 switches to programming mode. All subsequent read-in ID cards are authorized
according to the defined time zones (input "timer")
The ACC 50 switches to disable mode. In disable mode, ID-cards authorized so far, can be
disabled. All subsequently read-in cards are disabled in teh ACC 50. Notice the corresponding
time zone "A" and "B".
Attention! Clears the data memory completely and resets the ACC 50 to the
Only use for initial commissioning or when all ID cards require clearing.
