XR20 Introduction 3
Special Security Command Tones
Your keypad also contains a small speaker that allows it to alert you
to events as they occur on your system. Below are brief descriptions
of the different tones you will hear from the keypad:
Fire alert: Your keypad may sound a fire tone to alert persons in the
vicinity to the alarm condition. This is in addition to the bell output
from the alarm panel.
Burglary alert: Your keypad may sound a burglary tone to alert
persons in the vicinity to the alarm condition. This is in addition to
the bell output from the alarm panel.
Key press tone: A short beep as you press a key on the keypad.
Prewarn tone: A continuous pulsed tone that sounds when you open
an entry delay door on a system that is armed (turned on) reminding
you to disarm the burglary protection.
Monitor tone: A short tone that sounds for one second whenever a
door or window is opened while you are using the zone monitor
function from the User Menu. See Zone Monitor.
Trouble tone: A steady tone indicating a trouble condition on your
system. Press a Select key to silence the trouble tone.
Zone Activity Check tone: A steady tone indicating no zone activity
has occurred on your system within the programmed period of time.
Press any key to silence the tone.
What to do when the trouble tone is sounding
You can silence the trouble tone by pressing any one of
the top row Select keys. This only silences the keypad
and does not correct the condition that originally caused
the problem.
Special Security Command Messages
As you use your system, you will occasionally see a keypad display
that asks you to enter a user code or describes a condition on the
system. Below are some examples of the displays you will see.
ALARM
A 24-hour zone, such as a fire or panic zone, or an armed burglary
zone has been faulted. Your system may sound bells or sirens.
ALARM CANCELLED
This message displays when an authorized user has cancelled an
alarm condition by entering a valid user code and an “Alarm
Cancelled” report was sent to the central station.
TROUBLE
There is a problem with a protection device or system component.
This display is accompanied by a description of the problem.
ENTER CODE
The system requires you to enter a personal user code. User codes
can be required for turning your system on (arming), turning your
system off (disarming), and performing many other system options.
As you enter your user code, the keypad display shows an asterisk
(*) in place of each digit pressed. This prevents others from seeing
your user code on the display as it is entered. TRY AGAIN
The user code entered is not recognized by the system. Check the
user code and try again.
INVALID CODE
The user code you have entered is considered invalid by the system.
SYSTEM TROUBLE or SERVICE REQUIRED
There is an electronic failure in your system. Contact the service
department as soon as possible.
