102 AFC-600 Programming PN 51032:A 3/8/99
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
AFC-600, an NAC is one of four output circuits (TB7-TB10 on the MPS-6) 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 connector
J7 or J8 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
ALARM
SILENCE
key
function for 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. The AFC-600 provides two SLCs: SLC 1
which connects to TB5 and SLC 2 which connects to TB6.
Software Zone
A label, internal to the fire alarm system, assigned to a group of
addressable devices.
Special Annunciator
The AFC-600 supports ten point-addressable special
annunciators: Annunciators 0 - 9, programmable only through the VeriFire
programming utility. For more information, refer to the VeriFire 600 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.
Terminal Interface
EIA-232 bidirectional serial port (TB2) used for the upload and
download functions.
Terminal Mode
An operating mode for an LCD-80, LCD-80TM or MLD-1 that
allows communication with the control panel through the EIA-485 port (TB4).
