ARCHITECTURAL AND ENGINEERING SPECIFICATION, v 2.7
45
readers and points will be able to be stored at the Access Control
Panel. In the event of communication loss, the Access Control Panel
will continue to function without any degradation in operation, and will
provide storage for at least 1000 and utmost 210,000 transactions.
These stored events will be uploaded to the CPU automatically upon
the restoration of communications.
b.
Modem Communication:
The Access Control Panel shall be capable
of operating over standard telephone lines using external modems. An
Access Control Panel will automatically initiate a dial and will upload
stored information in case the storage buffer is 80% full or in case a
user defined alarm condition occurs. The CPU shall have the ability to
automatically request information from the remote Access Control
Panels based on a user defined time schedule.
c.
Direct Communication:
The Access Control Panel shall communicate
via an RS232 or RS422 link directly to the ACS CPU. No additional
interface equipment will be required. The Access Control Panel shall
be capable of being configured in either repeat mode (serial) or in
multi-drop mode. When in repeat mode, the distance between control
panels shall be up to 4000 feet, communicating at 57,600 baud,
without the use of modems or line drivers.
d.
Electrical Noise Suppression:
The controller shall have “Built-In”
electrical noise suppression devices to protect the on-board
microprocessor from relay-generated transients.
e.
Electrical Surge Protection:
The controller shall have “Built-In”
electronic surge protection devices to protect controller circuitry to
which external connections are made.
f.
Battery Backup:
The Access Control Panel shall include, as a
standard, at least 4 hours of battery backup. The Access Control Panel
also shall include internal battery backup to maintain controller
database, program, time and date during a power loss.
g.
Diagnostic LED’s:
The Access Control Panel shall have an LED
display to indicate power, processor heartbeat, and the transmission
and receipt of programmed data.
h.
Biometric Readers/Card Readers/Keypads:
The Access Control
Panel shall support entry/exit points that allow for a keypad to be used
in conjunction with the reader, and the keypad accepts user-definable
PIN codes. Systems requiring additional ports for the addition of a
keypad are not acceptable. The Access Control Panel shall be able to
support multiple card technologies (such as Proximity, Smart Readers,
Smart Cards, Biometric-Fingerprint, Iris Scan, Hand Geometry, Face
Recognition, Magnetic Stripe, Wiegand, etc.) concurrently without the
need for additional software or hardware.
i.
Inputs:
Without the need for any additional hardware, each Access
Control Panel will be able to monitor supervised alarm inputs. By
means of software download, the Access Control Panel shall allow the
user to decide whether the alarms must function as supervised or non-
supervised inputs.
5.
Outputs:
Without the need for any additional hardware, each Access Control Panel
will be able to control user-definable Form C relay outputs.
