Glossary
FMM-1 module An addressable monitor module that monitors conventional initiating devices.
NAC (Notification Appliance Circuit) A circuit or path directly connected to a notification appliance
device (a fire alarm system component--such as a bell, speaker, strobe, and so on--that produces an
audible output, a visual output, or both). On the NFS-640, a NAC is one of four output circuits on the
Control Panel with addresses B01-B04, panel circuits, control modules or transponder points.
new device A device connected to the control panel, but not in program memory.
non-latching An attribute of a device that follows the state of the fire alarm system. That is, if a
device is non-latching, it returns to its normal state automatically when the condition clears.
Notification Appliance Circuit see NAC.
obscuration A reduction in the atmospheric transparency caused by smoke, usually expressed in
percent per foot.
output circuit A control module connected to the SLC, a device connected to one of the four NACs,
or a Panel Circuit, such as an ICM-4.
Panel Circuit A circuit on a module connected to the control panel through connectors on the control
panel. The control panel identifies a Panel Circuit with the addressing convention Px.x. For example
P1.4, indicates Panel Circuit 4 on the first module connected to the control panel.
point A system memory address occupied by an addressable SLC device, Software Zone, or
annunciator. For example, the control panel considers "1M102", a module on SLC 1 at SLC address
102, as a point.
panel sounder The piezo sounder on control panel, that pulses when troubles and alarms occur.
Silence Inhibit Timer A user-defined timer that disables the
programmed time (0-300 seconds) when a fire alarm occurs. The timer starts at the first alarm and
restarts with each new alarm.
SLC (Signaling Line Circuit) A physical wire loop used to connect addressable detectors and modules
to the control panel.
Software Zone A label, internal to the fire alarm system, assigned to a group of addressable devices.
Special Annunciator The NFS-640 supports ten point-addressable special annunciators:
Annunciators 0 - 9, programmable only through the VeriFire™ Tools programming utility. For more
information, refer to the VeriFire™ Tools CD on-line help .
status banner A text message in an LCD display that typically provides the description of the
device or the status of a device.
Switch Inhibit A software function that lets you program control modules, NACs, and Panel Circuits
so an operator cannot manually activate NAC or releasing circuits. With Switch Inhibit enabled, an
operator cannot manually activate the NAC/releasing circuits from the control panel.
SYSTEM NORMAL message A message that displays, along with the current system date and
time, on the bottom line of the LCD display during normal operation of the control panel.
Terminal Interface EIA-232 bidirectional serial port used for the upload and download functions.
Terminal Mode An operating mode for an LCD-80 or LCD-80TM that allows communication with
the control panel through the EIA-485 port.
Type Code A Type Code is a software function that specifies the function of a detector, control
module, monitor module, transponder point, NAC, or Panel Circuit point. (You can select a Type Code
while programming a point). The Type Code specifies what action the control panel takes when the
point activates. For example, when a monitor module with
control panel activates all outputs, as if someone pressed the
upload A function for making a copy of a system program and storing the program as a file on a
personal computer. Also see VeriFire™ Tools.
