Example:
Calculation:
Result:
The memory requirements for an ACS-8 controller is calculated based on the following
conditions:
- 10,000 ESSER-coded contactless / proximity cards
- 6-digit PIN code
- 20 room/time zones
- Antipassback control
- Control of 7 macros
- 100,000 bookings
- 5 timers for BRE
A 1 MB memory extension is required.
If the memory space required is calculated to exceed the maximum available free memory
space, alternative calculations using various lower values can be carried out. For example,
the number of bookings to be stored can be reduced. Is it possible to switch less relays?
Are all room schedules really required?
Approximate value
The standard memory of 1 MB (0.5 MB free) based on the calculation above is sufficient for
approximately 1.500 cards and approximately 20000 bookings.
The required memory space for both of those values will be displayed by entering the max.
ID card / max. areas in IQ NetEdit (for details see installation manual IQ MultiAccess,
P32205-26-0G0-xx, additional tab).
