PART I: INTRODUCTION
3.4 Function Key Sequences
There are a number of functions detailed in this
User’s Guide to carry out various tasks (for example,
adding or deleting PINs, setting the date and time or
testing the system).
Functions are written out using their keypad key
sequences. Many of these functions also have titles.
For example, [#] + [4] + [1] is the System Test
function. To conduct this function, press the [#] key,
followed by the [4] key and then the [1] key.
3.5 System Events
Your system responds to four types of alarm events. If
more than one event occurs, your system sorts them
into one of four groups:
• Fire Alarms (highest priority)
• Burglary Alarms
• Fire Troubles
• Non-Fire Troubles (lowest priority)
Events that are grouped as highest priority are always
sent to the Central Station first.
3.5.1 Fire Alarms
Fire alarms are the highest priority events. When a
fire zone activates, your keypad emits a Fire Alarm
tone. The tone sounds for the length of time
programmed by your Security Company. Evacuate all
occupants and investigate for smoke or fire. Enter a
valid user PIN to silence the alarm.
Make sure that all occupants know the
difference between the Burglary Alarm Tone
and the Fire Alarm Tone.
3.5.2 Burglary Alarms
Burglary alarms are the second priority. When a
burglary zone activates, your keypad emits a Burglary
Alarm tone. The tone sounds for the length of time set
by your Security Company. Enter a valid user PIN to
silence the alarm.
Make sure that all occupants know the
difference between the Burglary Alarm Tone
and the Fire Alarm Tone.
The keypad scrolls through each zone alarm. Press
the [*] key to manually advance the list.
3.5.3 Fire Trouble Events
When a fire trouble (such as a loose wire) occurs,
your keypad emits a Trouble tone.
The keypad displays the SYSTEM TROUBLE
message. See “Check System Troubles” on pages 18
and 40 for more information on determining the nature
of the trouble.
3.5.4 Non-Fire Trouble Events
When a trouble event such as a low battery condition
occurs, your keypad emits a Trouble tone.
The keypad displays the SYSTEM TROUBLE
message. See “Check System Troubles” on pages
18 and 40 for more information on determining the
nature of the trouble.
3.6 How Your System Reports Alarms
Your security system may be programmed to
automatically seize your telephone when sending
reports to your Security Company. Once the report is
complete, the system returns the telephone to normal
operation (check with your Security Company).
Your system makes repeated attempts to send
reports to your Security Company. If your system fails
to report, the keypad signals a system trouble. See
“Check System Troubles” on pages 18 and 40 for
more information on determining the nature of the
trouble.
If your telephone service is interrupted, your
security system cannot send reports to your
Security Company unless it has an alternate
means of transmitting them.
3.7 Check System Status (DS7447i Only)

current system status. The following messages may

3.8 Logging Out of the System
The system remembers PIN entries for approximately
10 seconds after you stop pressing keys. To log out of
the system, press the [#] key twice.

display.
