4 XR20 Introduction
Understanding Security System Terms
Throughout this guide, and in some displays on your keypad, you will
see certain words or phrases that might be unfamiliar. Although
every effort has been made to use terms that are commonly known,
there are some for which there was no acceptable substitute.
Below are some terms you will see here and on the keypad display.
Arming
This is the term used for turning on the burglary protection in one
or more areas of the system. Your system may require you to enter
a user code. When armed, the system is able to sound alarm bells
or sirens and, if monitored, send alarm reports to a central station
when a burglary zone is faulted.
Fire, panic, and other 24-hour devices are always turned on and do
not need to be armed.
Disarming
This means turning off one or more areas of the system. When
disarmed, the system does NOT sound alarms or send alarm reports
to a central station when a burglary zone is faulted.
Zone
A zone refers to a group of one or more protected openings or
protection devices assigned the same zone number. Each door or
window, motion detector, smoke detector, or other device has a
zone number and a name.
Often, similar devices in the same general area will share the same
zone. For example, the windows on the east side of the premises
can all be grouped together in a zone named E. WINDOWS.
Entry or Exit Zone
Almost all systems have one or more doors through which you can
enter or exit the premises. These doors are programmed with a
delay time to allow you to enter or exit while the system is armed
without setting off the alarm.
When you arm the system, activity on all burglary zones is ignored
until the programmed exit delay time expires. Once that time has
expired and the system is fully armed, opening the door causes the
panel to start the entry delay time. During the entry delay time, you
must enter a valid user code to disarm the system or an alarm will
occur.
Instant Zone
Exterior windows and non-entry doors, or interior protection devices,
are typically not programmed with delay times. If these zones are
faulted while the system is armed, an alarm occurs instantly.
24-Hour Zone
A 24-hour zone is never assigned to an area and is not turned on or
off by arming or disarming your system. Some examples of 24-hour
zones are fire zones, panic zones, and temperature control zones.
Areas
An area is made up of burglary zones that can be armed or disarmed
together. The Perimeter area, for example, consists of all the doors
and windows on the outside of the building. When you arm the
Perimeter, these zones sound an alarm if tripped.
