4. Response Tones
7.
All command centers contain a sounder used to
annunciate several system conditions and account
conditions. The response tones for the
D636A
are as
follows:
Entrance Warning
-
The command center emits a
pulsating beep during the entry delay period to
remind the user to disarm the security system. This
is a programmable function
of
the D4112 and
D6112.
The only difference between the D636 and the
D636A
is
the addition of the keypad backlight jumper (W4) which is
present on the
D636A
Command Center (refer to Figure
3) and a product ID label on the back of the command
center base. These are the only visual indications
between the two assemblies.
Keystroke Entry
-
As each key is touched the
command center emits a short beep to indicate that
the entry has been stored in the command center
buffer.
Figure 3 also illustrates the difference between a new
D636A
and a D636 converted to a
D636A.
Faulted Zone Protest
-
The system may be
programmed to sound the account command center
buzzer for two seconds after an arming attempt has
been made, to indicate that a zone is faulted.
When the backlight jumper (W4) is cut, the
D636A
digital
keypad backlighting will only illuminate when a digit is
pressed, when the alarm system is in the entry delay
mode, during alarm memory, or if a digit is pressed.
When the jumper is left intact, the
D636A
digital keypad
is continuously illuminated.
Watch Tone
-
The command center sounder emits
a short beep when a perimeter zone is faulted during
the perimeter watch mode.
Service Tone
-
Some zones may be programmed to
sound a service tone when they are faulted. To
silence the sounder enter your passcode, plus
ENTER, or enter COMMAND 4.
NOTE:
Some zones, such as fire zones, may be
programmed so that the sounder cannot be silenced
until the zone
fault
is corrected (see the
D61
12: MAIN
Program Entry Guide or
D41
72
installation
and
Programming Manual).
Telephone Trouble
-
In a reporting system when the
phone line is disconnected or the system is unable to
make contact with the Central Station receiver, the
Command Center beeps until the situation is
corrected, or a personal
passcode
or COMMAND 4
is entered.
5.
Zone Annunciation
The
D636A
Command Center can display information for
up to sixteen protective zones.
6. Command Center Sounder Disable
_
To permanently disable the sounder; remove all power
from the
Command Center, cut the
leads on
resistor R36
(see Figure 2),
and remove this component.
D636 AFTER CONVERSION
NOTE:
For U.L. installations, the sounder on at least one
Command Center in the
D4112/D6112
system must
remain connected.
