Installation instructions / ACS-2 plus 35
3
The new trademark corresponds with the previous effeff coding.
Example: The memory requirements for an ACS-2 plus controller is to be calculated based on the following
conditions:
10,000 ESSER coded contactless cards
3
6-digit PIN code
20 room/time zones
Antipassback control
Control of 7 macros
100,000 bookings
5 timers for BRE
Calculation:
Result: A 1 MB memory extension is required.
If the calculated required memory space exceeds the max. free memory space, alternative calculations
using various lower values can be carried out. It is, for example, possible to reduce the number of bookings
to be stored. Is it possible to switch less relays? Do you really require all room/time zones?
Approximate value
The standard equipment of 1 MB (0.5 MB free) is sufficient, according to the above mentioned calculation
method, for approx. 1,500 cards and approx. 20,000 bookings.
The required memory space for both of zones and ID cards will be displayed when the maximum values
are entered in IQ NetEdit (refer to the IQ MultiAccess Installation Instructions, P32205-26-0G0-xx,
additional settings tab).
