REGULATORY CONSIDERATIONS
IMPORTANT SAFETY INFORMATION
The Super Two is defined as a Stand-Alone Access Control
System. The PC connection provides convenient setup and
monitoring of the system, but all decision-making for a card-
holder's authorizations at a particular time and place are made
by the Access Control Panel. Likewise, all time-controlled
relay activities and link functions of the Access Control Panel
and the Alarm/Relay Expansion Unit do not depend upon the
normal operation of the PC. During disruptions in the opera-
tion of the PC, or the communications link with the PC, Ac-
cess Transactions, Alarm Events, and other activities are
logged in the individual Access Control Panel. When commu-
nication is restored, these buffered transactions are transferred
to the PC.
The Expansion Unit is to be installed in a secured area. Never-
theless, because opening the enclosure door gives access to
terminals that can allow false signals, a tamper switch is in-
stalled on the door. The tamper switch must be configured at
the host computer to signal an alert when the tamper switch is
an open-circuit. The tamper switch may also be configured to
activate the console relay, which may then be wired into a Bur-
glar Alarm Signal Circuit or an Alarm Sounding Circuit.
In some localities, the Alarm Circuit and Relay Circuit 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 will be acceptable. In Canadian installations,
CSA CMG FT4 foil-shielded cabling may be used in non-
plenum installations, and CSA CMP FT6 foil-shielded cabling
may be used in installations requiring plenum ratings.
Supervised Alarm / Relay / Power Expansion Unit
The Expansion Unit must be installed on a wall, permanently
connected to the AC Mains. To minimize disruptive effects
from ground loops, use the same AC branch circuit that pow-
ers the Access Control Panel.
Fault-Tolerance, Fault Isolation, and Conditions that
may result in impaired operation.
Sensing the status of the Accessory Alarm Inputs will be im-
paired by a cut cable or short-circuit in the Alarm Signal Cir-
cuit wiring. By installing end-of-line termination resistors, as
described in this manual, the Alarm Circuits may be super-
vised to detect such faults and indicate the need for a repair.
The Access Control Panel constantly exchanges data with the
Alarm/Relay Expansion Board through the modular cable. If
the cable is disconnected while the units are powered, no
equipment damage will occur, but setup data stored in the Ex-
pansion Board will be lost. When the cable is reconnected, the
relays will not be activated. Self-Test Firmware in the Access
Control Panel will detect this disruption, and restore the setup
data and relay activation within one minute. Resetting the Ac-
cess Control Panel will immediately restore normal operation
of the Expansion Units. The 12 Volt output of the Power Sup-
ply is inherently Power-Limited. The Charger Board uses self-
resetting current limiting devices in the Accessory Output cir-
cuit and the Backup Battery circuit.
