CENTRALIZED ACCESS CONTROL AND ALARM LOOP ARMING/DISARMING
If the S2000-2 controller operates as a part of an Orion system, it provides not only local but central-
ized control for all its operation modes ( Two Entrance Doors , One Entrance/Exit Door , Turnstile ,
Swing-beam Barrier and Two Sluice Doors ). Local control means that codes of keys are stored in the
controller memory, so a key owner can gain access only through this local access point or/and only
arm/disarm alarm loops of S2000-2 which ‘knows’ the key code. Centralized control means that key
codes are stored not in the memory of a S2000-2 but in the memory of a network controller. When the
Orion system operates under ARM Orion Workstation the owner of any key stored in Orion database
can gain access through any system access point that is permitted for this key or arm/disarm any
permitted alarm loop in the system. If the system operates under C2000/C2000M controller only cen-
tralized arming/disarming is enabled.
Similarly to local stored keys centralized control keys can be combined, that is used both for access
gaining and partition arming/disarming. Besides, local access can be combined with centralized parti-
tion arming/disarming (the Access attribute must be set for the access group descriptor of a key in the
controller memory to implement such operation).
If an identifier is presented to one of the controller readers and this identifier is unknown to the con-
troller, the code of the identifier is sent to the network controller. The reader LED starts flashing with
red and green alternately 5 times per second until the answer from the S2000/S2000M or PC is re-
ceived (this may take from fractions of a second to several seconds, depending on the number of de-
vices, connected to the RS-485 interface).
If the network controller ( ARM Orion ) makes the decision to grant access, the centralized access is
granted by the same way as the local one.
If the presented key is authorized to arm/disarm a system partition, the current partition status will be
displayed by the reader LED as shown in Table 1. Repeated presenting of the key will initiate arming
(provided the partition is disarmed) or disarming (in all the other cases) of the partition. Each subse-
quent presenting of the identifier will initiate activity, which is contrary to previous one, i.e. if the sec-
ond presenting of the key initiates the partition disarming, the third presenting of the key would initiate
the partition arming, etc. If rights assigned to the key are limited, for example, only arming is author-
ized, the repeated (as well as all the subsequent) presenting of the key will initiate only the authorized
action (arming) regardless of the current state of the partition.
If the presented identifier is unknown to the network controller or the identifier has no relevant access
rights, the controller indicates access denying so as the controller and reader sounders initiate the
long sound signal (Error), the reader LED flashes three times and then lights red steady.
