No, absolutely not.
The SROS10 can be installed using a local locking system activated by a key fob or any other number of devices.
By not having an access control system you lose the logging facility of course as you will not know who and when went to SROS10 monitor. There are alternatives. We work with BG Systems, developer of the iMan system. This system can be configured to record and log all kinds of actions and reactions such as the SROS10 door being opened, alarms being triggered, alarms being acknowledged etc.
