System information
ATS 2000/3000/4000/4500 Programming manual 171
Door contact A magnetic contact used to detect if a door or window is opened.
Door control The control over door functions.
Door group An ATS feature that assigns a group of doors or lifts to a user, in order to
allow access to those doors/lifts. Access to each door in a group can be
restricted via a timezone.
DUAL Dual detector. A security device used to detect intruders in a certain part
of an area or premise. The technique used is based on two techniques
like PIR and RADAR or PIR and Ultrasonic.
Duress A situation where a user is being forced to breach the system security
(e.g. forced at gunpoint to open the door). The ATS duress facility allows a
signal to be activated (e.g. notification to a central station) by the user.
This is done by entering a duress digit in conjunction with a PIN code.
Engineer Personel from an installer that is able to install and service the control
panel.
Event flags A signal activated by a zone condition, area condition, system status or
fault condition, door command (on doors 1 to 16) or shunt condition. The
main purpose of an event flag is to activate an output.
Fire alarm An alarm triggered by fire or smoke detectors indicating a fire.
Floor group An ATS feature that assigns a group of floors to a user, in order to allow
selection of floors when accessing a lift reader. Access to each floor in a
group can be restricted via a timezone.
Floor control See Door control.
History A list of past alarm and access control events stored in memory that can
be viewed on an LCD arming station or sent to a printer.
Hold-up A (silent) alarm that is triggered by a hold-up button. Normally it will not
trigger any siren, only send a message to a central station.
Inhibit See Normal/Active/Tamper/Inhibited
Installer A company that installs and services security equipment.
Keypad A remote arming station with keys to input data (keypad). Used to
program the control panel, perform user functions, view alarms, etc.
Keyswitch A device using a switch to arm or disarm areas. The switch needs a key to
switch.
LCD (Liquid Crystal Display). The part of an arming station where messages
are displayed.
LED (Light Emitting Diode). A light indicator on an arming station which
conveys a condition. E.g.; area in alarm, communication fault, etc.
Local alarm An alarm that is signalled only within a premise and occurs when an area
is occupied. The circumstances that cause a local alarm can be checked
and rectified by personnel on site and it is therefore unnecessary for the
alarm to be reported to a central station.
Logic equation A logic expression that combines macro inputs in a specific manner. The
result of a logic equation is called a macro output.
Macro input An event flag or an output that is used in a logic equation. Each macro
input is an event flag or output.
Macro logic program A set of rules that is created by macro inputs, logic equations and macro
outputs that is used to trigger event flags or zones.
Macro output A macro output holds the result of a logic equation. The macro output can
have a timing element. Macro outputs trigger event flags or zones.
Normal/Active/Tamper/Inhibited Describes the condition of a zone.
Normal: The zone is NOT activated. E.g. Fire Exit Door closed
Active: The zone is activated. E.g. Fire Exit Door open
Tamper: The zone is open or short circuited. Someone may have
