Application / functions

The ACC 50 checks and monitors the access to a door.
The door strike is released and the appertaining door can be opened with an authorized ID-
card. The release time depends on the position of the DIP switches.
In addition to that, the ACC 50 takes over the door monitoring function. When a door strike
with monitoring contact is used, this contact reports whether the door is open or shut. After
run-down of the adjusted monitoring time the ACC 50 can trigger with the lock contact an
alarm on an intrusion detection system or an alarm signalling device (signal lamp, flash
signal, horn etc.).
An external door strike key which is located in the secured area allows a manual door
release.
2 time zones the ID-cards can be assigned to, can be defined by an external timer.
Example:Time zone "A" = 07:00 o'clock... 19:00 o'clock
Depending on the assignment certain persons have access authorization only within time
zone "A", only within time zone "B" or for both time zones.
The ACC 50 is programmed by means of the programming card set. When programming
the programming card set the ACC 50 stores the numbers of the cards once. Then other
programming cards are no longer authorized, that means other card sets are disabled.

Handling of the ID cards

The cards are reliable and clearly identified, as long as the distance to the ACC 50 is not exceeded.
The receiver unit of the ACC 50 is in the upper third. The best distance is 5-10 cm and the card has to
be held parallel in front of the unit. Just pull by the card in front of the ACC 50 to achieve a reliable
reading of the card.
The principle of the contactless cards:
The interior of the card is composed of an oscillating circuit and a microchip with the stored code of the
card. The ACC 50 emits a weak electromagnetic field, which is in resonance with the oscillating circuit
of the card. Now the card modulates the receiving frequency with its bit pattern which is received by
the ACC 50.
Eeach contactless cards offered by our company is a unique. Each existing card has another data
information..
Time zone "B" = 19:00 o'clock ... 07:00 o'clock
