1.0 About This User’s Guide
This User’s Guide shows you how to use and
maintain your security system. It covers basic
functions, such as turning the system on and off.
Your Security Company has programmed the
functions described in this User’s Guide, however not
all of them may be enabled in your system.
Certain functions covered may require you to enter
your Personal Identification Number (PIN).
Your system helps to secure life, property, and
investments against fire, theft and bodily harm. It may
consist of one or more keypads, motion sensors (for
example, detectors or devices located on doors and
windows) and sensing devices designed to detect the
presence of smoke or combustion. Each of these
devices is connected to a sophisticated control panel
with microprocessor, which processes all events
registered by the system.
Control of your security system is achieved through
the keypad, which offers a variety of basic and
advanced features. Its function, versatility, and ease
of operation make it ideal for home or office use. The
keypad is tailored to meet your individual needs.
Moreover, it has been designed with you, the user, in
mind.

2.0 Security System Basics
2.1 What is a Zone?
A Zone is a detection device or group of devices
connected to your security system. Zones are
identified by the area they monitor, such as a front
door, bedroom window or hallway.
2.2 What is a Faulted Zone?
When a zone (such as a door or window) is closed, it
is said to be normal. When the door or window is
open, the zone is said to be faulted, or not normal.
When you turn your system on, you usually want all of
the zones in your system to be normal. However, you
can turn your system on with faulted zones by using
the Bypass Zones function (see page 13).
You can see if there are any faulted zones by entering
a valid user PIN followed by the [#] + [0] keys when
the system is off.
2.3 Are All Zones the Same?
Not all zones are the same. In fact, there are two
basic types of zones: Controlled and 24-hour.
2.3.1 Controlled Zones
Controlled zones respond to alarm conditions
depending upon whether the system is turned on or
off. They are programmed to either respond instantly
to alarm conditions, or to provide a delay for you to
reach the keypad and turn the system off. Various
controlled zones may be located throughout your
house.
When you turn your system on, you have the option of
turning on all controlled zones (All On), or just some
of the controlled zones (Perimeter Only or Partial On).
See page 5 for more information on “All On”,
“Perimeter Only” and “Partial On.”
2.3.2 24-hour Zones
24-hour zones are always on, even when the system
is turned off. There are two types of 24-hour zones,
fire zones and non-fire zones.
• Fire Zones: Fire zones only monitor fire
detection devices such as smoke detectors.
They are always on and cannot be turned off.
• Non-fire 24-hour Zones: Non-fire 24-hour
zones are always on and cannot be turned off.
