Glossary
Keyswitch (Momentary)
To operate a momentary keyswitch, insert the key, turn it, and then release it. The key returns
to the starting position automatically. The key cannot be removed unless it is in the starting
position.
Keyswitch (Maintained)
A maintained keyswitch typically has two positions marked “Armed” and “Disarmed.” To
operate, insert the key, turn the key to the desired position, and remove the key.
Latching
The locking in of a circuit by means of a holding contact.
Modem IIIa
2
Modem IIIa
2
is a Bosch Security Systems 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
P
ublic
S

T
elephone
N
etwork. An assembly of communications facilities and central
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 an 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 construct “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-hr. 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.
