Glossary
0.1 Glossary
This section contains descriptions of terms essential to know when programming the control panel.
Alarm History See History buffer.
Alarm Verification Timer A user-defined global software timer function that can reduce the
number of nuisance alarms. When you select Alarm Verification for a detector, the control panel
delays an alarm signal for a user-specified time period. (The control panel ignores the Alarm
Verification Timer if it detects another alarm during the verification period.)
Argument An argument is a discrete part of a logic function used in a CBE logic or trouble
equation. It can consist of panel/SLC addresses for detectors, modules, panel modules, zones,
special function zones, logic or trouble equations.
Auto Silence Timer A user-defined global software timer that functions like pressing the signal
silence key. The control panel silences all active outputs programmed as silenceable once the timer
has reached the selected time. For example, if 20 minutes is selected, when the timer reaches 20
minutes the control panel turns off all active outputs programmed as silenceable.
Autoprogram A software routine that directs the control panel to identify and automatically load
SLC-connected devices into the program with default values for all parameters. The Autoprogram
Finds and displays all new or missing intelligent detectors and modules--while ignoring devices
already installed in memory--so you can edit default option selections. Typically, you Autoprogram
the control panel as a first step in a new installation, or to add devices.
Control module An addressable module that a) switches power to a Style Y or Style Z NAC; or b)
functions as a Form-C control relay.
CBE (Control-by-Event) A programming method that lets you map inputs and outputs to provide a
variety of output responses based on various initiating conditions (events).
C LIP poll - Classic Loop Interface Protocol - CLIP - is standard polling of each intelligent device
(as differentiated from FlashScan poll, a method of group polling described below).
DCC (Display and Control Center) - Term for a display location, programmed to participate in
DCC, when it has control of Acknowledge, Signal Silence, System Reset and Drill functions.
Drift Compensation An algorithm which permits the maintenance of a constant smoke detector
sensitivity by accounting for environmental contaminants and other factors.
Download A function for loading a system program from a file on a personal computer and storing
the program in system memory of the control panel. Also see Veri•Fire.
FlashScan poll - a patented system (US Patent Number 5,539,389) that enhances the speed of
communication between analog intelligent devices. Communication is in a grouped fashion. When
one of the devices within the group has new information, the panel CPU stops the group poll and
concentrates on single points.
History buffer The control panel maintains a history buffer of the last 4000 events, each with a
time and date stamp. History events include all alarms, troubles, operator actions, and
programming entries. The control panel also maintains a 1000-event Alarm History buffer, which
consists of the 1000 most recent alarm events from the 4000-event history buffer.
latching An attribute of a device that keeps it in an active state until the condition causing the
activation is corrected and the panel is reset.
Missing device A device that exists in a program, but is not found by the control panel during
Autoprogram, typically because the device is disconnected.
