D6412/D4412
Glossary
Latching: The locking in of a circuit by means of a holding contact.
Modem IIIa
2
: Modem IIIa
2
is a Radionics reporting format (protocol) the D6412/D4412 uses to communicate to
central station receivers. Even though you can program the panel to report in other formats, only
Modem IIIa
2
reports are referenced in this document. If you choose an alternate reporting format,
see the D6412/D4412 Program Entry Guide (P/N: 45351) to determine which report is
substituted for the Modem IIIa
2
report.
Nibble: Once the installer selects a value for a parameter, the panel stores the selection in E2 memory
“Nibbles.” Each parameter uses one or more Nibbles. When programming from the Command
Center, the installer enters a selection directly into the memory Nibbles. When programming
from the remote programmer (RAM IV), the installer need only make one entry per parameter.
No Delay: Turning the system on without Entry or Exit Delay.
Off: The controlled points are not armed (system is off).
Off Display: The display that appears when the system is turned off and no keys have been pressed (normal
display).
Options: Options are a unique type of parameter that allow the installer to configure up to four features by
entering a value in a single Nibble.
PSTN: Public Switched Telephone Network. An assembly of communications facilities and cantral office
equipment operated jointly by authorized common carriers that provides the general public with
the ability to establish communications channels via discrete dialing codes.
Parameter: Each program parameter sets a specific value or chooses an option.
Part On: An installer-defined subset of the controlled points. Part On with No Delay (Instant) is an option.
No Exit or Entry Delay is provided with the No Delay option.
Part 2 On: A user-defined subset of the controlled points. Part 2 On with No Delay (Instant) is an option. No
Exit or Entry Delay is provided with the No Delay option.
Points: The panel reports changing conditions on the sensor loops it monitors as “point” events. For
example, when the condition on On-board Sensor Loop 1 changes from normal (supervised,
EOL resistor in place) to shorted, the panel can be programmed to create ana alarm event for
Point 1. That alarm event appears in command center displays as “Alarm, Pt 1.” If programmed
for reporting , the panel would send an “Alarm, Pt 1” report to the central station receiver in the
Modem IIIa
2
format. Other reporting formats typically use “Zones” (Zn). in their reports instead of
“Points.”
Point Index: Used to contruct “personality types” for points used in the D6412/D4412 system. Each unique
point index number determines responses to specific conditions occurring on the protected
points.
Point Type: Describes what the point does (for example, fire point, burglary point, 24-hour point, etc.).
Point Scan Time: The amount of time that passes while a point is electronically off-normal. This duration
determines the length of a pulse.
Programmable Outputs: The D6412 provides up to 20 programmable outputs (D4412 provides up to 12). These outputs
are activated by installer-selectable panel events. Event options include alarms, troubles, and
scheduled events (Skeds). The panel’s on-board outputs provide power or dry contact switching
upon activation. When programmed to activate on alarm events, outputs are sometimes
described as “bell.” In some Modem IIIa
2
reports, outputs are described as “relay.”
Pulse Count: A feature of an intrusion detection system in which an alarm is triggered only after there has
been a series of detections in a short period of time. A pulse count is used in difficult
environments where false alarms are a problem.
RAM IV: RAM (Remote Account Manager) IV is a Windows
-based account management and panel
programming utility designed to remotely set up and program specific control panels.
Remote Programming: System programming by means of the system user’s telephone line.
Restoral Report: A signal transmitted upon the removal of a trouble or alarm condition from an alarm circuit.
SDI: Serial Device Interface.
