h.
Holiday Types:
The Access Control Panel shall allow for up to 5
Holiday types. Each Holiday type will consist of different Holiday
schedules.
i.
Access Modes:
Each card reader/keypad shall have the ability to
operate independently in up to five different modes: Card only,
Common Code only, Card plus PIN, Free Access & Card or Card #
through keypad. These modes of operation will be able to be
programmed from the ACS host computer and can automatically
change according to time schedule assignment.
j.
Anti-pass back:
The Access Control Panel shall support anti-pass
back operation in which, the cardholders are required to follow a
proper in/out sequence.
WW.
Controllers
1. Continental Access manufactures different kinds of Access Control Panels in 2, 4
and 8 door configurations.
2.
General Features:
a.
PC Board:
The aforementioned Access Control Panels shall be
microprocessor controlled solid-state electronic devices and shall
include a real time clock/calendar on board. They shall be compliant
with UL294 or equal. A subset of the ACS database sufficient to
support access and alarm functions for their designated readers and
points will be able to be stored at the Access Control Panel. In the
event of communication loss, the Access Control Panels will continue
to function without any degradation in operation, and will provide
storage for a minimum of 20,000 cardholders and at least 1000
transactions.
b.
Modem Communication:
The aforementioned Access Control Panels
shall be capable of operating over standard telephone lines using
external modems. They shall automatically initiate a dial and upload
stored transactions if the storage buffer is 80% full or if a user-defined
alarm condition occurs. The CPU also shall have the ability to request
information automatically from the remote Access Control Panels
based on a user- defined time schedule.
c.
Network Communication:
The aforementioned Access Control
Panels shall support the use of network communication devices to
provide communication over LAN and WAN systems.
d.
Direct Communication:
The Access Control Panels shall
communicate via an RS-232 or RS-422 link directly to the ACS CPU.
No additional interface equipment will be required. The Access Control
Panels shall be capable of being configured in either repeat mode
(serial) or in multi-drop mode. When in repeat mode, the distance
between the control panels may not exceed 4000 feet. The control
panels shall need to be communicating at 57,600 baud, without the
use of modems or line drivers.
e.
Battery Backup:
As a standard, the Access Control Panels shall
include at least 4 hours of battery backup (7AH). They shall also
include internal battery backup to maintain controller database,
program, time and date during a power loss.
