Accelaterm
®
Installation and Service Manual 6
IMPORTANT SAFETY INFORMATION
The Accelaterm has been evaluated by UL as a Stand-Alone
Access Control System (Burglary and Fire Alarm features
have not been evaluate by UL). The PC connection pro-
vides convenient setup and monitoring of the system, but all
decision-making for a Cardholder’s Authorizations at a par-
ticular time and place are made by the Access Control
Panel.
Disruptions to the communication with the PC, or to the
operation of the PC itself will not result in impaired opera-
tion of the Access Control System.
The Accelaterm Access Control panel is to be installed in a
secured area. Nevertheless, because opening the enclosure
door gives access to terminals that can allow an invalid en-
trance, a tamper switch is installed on the door. The tamper
switch must be configured at the Host Computer to signal
an alert when the tamper switch is activated. The tamper
switch may also be configured to activate the console relay,
which may then be wired into an Alarm Signal Circuit or an
Alarm Sounding Circuit.
In some localities, the Access Control System Reader, Se-
rial Communication, Door Lock Circuits and other signal
wiring may use UL Type CM or UL Type CL2 foil-
shielded multi-conductor and multi-pair cable. Where the
AHJ's (Authorities Having Jurisdiction) require Plenum-
Rated Cabling, UL Type CL2P cabling may be acceptable.
All external wiring must be UL Listed, suitable for the
installation application.
Replace the lithium backup battery on the Interface Board
with a Rayovac "BR1225E" coin cell. Use of another bat-
tery may present a risk of fire or explosion.
The Accelaterm must be installed on a wall, permanently
connected to the AC Mains.
Fault-Tolerance, Fault Isolation, and Conditions that
may result in impaired operation
As described above, a faulted computer or communication
link with the computer will not impact the ongoing access
management of the Access Control Panel. Furthermore, the
transactions occurring during the equipment outage will be
recorded in the Access Control Panel, then forwarded to the
computer when the fault is removed.
If the Access Control Panel itself fails due to a long-term
power failure or internal fault, the Access Control Software
on the host computer will normally detect this failure, sig-
nal an alert, and log the time of this event.
Sensing the status of the Door Monitor Contacts, the Re-
quest to Exit (REX) and the Accessory Alarm Inputs will be
impaired by a cut cable or short-circuit in the Signal Circuit
Wiring. By installing end-of-line termination resistors, as
described in this manual, the Alarm and Signal Circuits
may be supervised to detect such faults and indicate the
need for a repair.
