Product Name(s): APC-300 Access Point Controller
Product Description: The APC-300 is a LonMark-certified card access controller that controls access to one or two doors or gates, or one elevator cab.
Product Application(s): The APC-300 provides economical access control with a designed-in high level of interoperability with other multivendor building automation DDC controllers and subsystems, such as HVAC and lighting. Features: - includes two Wiegand proximity reader/keypad interfaces and two door-control interfaces for independent or in/out access control - supports multiple card formats up to 128 bits - stores 10,000 access users, 64 access groups and 64 schedules in powerfail-protected database - includes a 1,500-entry event and alarm log - supports configurable events and alarms for logging, monitoring and alarm notification - supports antipassback control - ships ready for construction mode operation - works with Circon's Access Integrator 3 application software, for administration and alarm/event annunciating and archiving

* Items in NV memory are not lost upon power or battery failure. Other types of NV memory such as EPROM, NOVROM, etc. do not directly impact system performance.
Can trend data be stored in this controller? As the application of the APC-300 is access control, it does not trend in the traditional HVAC sense. It does ,however, record events and alarms that the integrator configures it to record, such as access granted, access denied, door opened, door closed, door forced open and so on. These events are stored in the controller's event log. They can also be confirgured to be pushed to the HMI PC in realtime.
How many total trend values can be stored? The event log capacity is 1,500 events.
What is the controllers role in trending? The controller's sequence of operation decides when these events are detected and records the event in the event log. If so configured, it pushes the event to the PC running Access Integrator 3.
Can controller be programmed to 'push' data to archive or are trends 'pulled' from controller?
When full, does controller automatically send up trend data, overwrite data, or stop logging data? Overwrite oldest data
Programming Method(s) Uses a template-based form of programming. Configuration performed on laptop/PC running LNS network management tool and the device-specific configuration LNS plug-in supplied by Circon.
Access users, access groups, card data, and schedules are configured on PC running Access Integrator 3, and downloaded to APC-300 over LonWorks network.
Resident vs Non-Resident Program Execution All program execution is controller resident.
Resident/Supervisory. This controller supervises the scheduling of other controllers.
Resident/Stand Alone. This controller contains its own schedule.
Non-Resident. This controller is dependent upon another controller for its schedule.
None. This controller has no scheduling features.

Automatically reset/synchronize the clock? Controller maintains clock during power outage for up to 10 hours. It automatically resyncronizes with master clock PC or device via network variable.
Update all monitored functions? Yes
Generate an alarm if backup battery is dead? no battery
Upon network or communications failure does controller:
Continue to operate standalone? Yes
Operate with last global settings or user-specified value? N.A.
Do broken network segments continue to communicate within the remaining segment?
(Note: May depend on proper termination of segments for higher speed networks.)
Does network automatically reconfigure upon restoration? Yes, network variable bindings
Does network store 'loss of communications' alarm with time of event? Yes
