1.4FCC Notice
This equipment generates and uses radio frequency energy. If not installed in accordance with the manufacturer’s
instructions, it may cause interference to radio and television reception. It has been type tested and found to comply with the
specifications in Sub-part J of Part 15 of FCC rules for Class B Computing Devices. If this equipment causes interference to
radio or television reception - which can be determined by turning the equipment on and off - the installer is encouraged to
correct the interference by one or more of the following measures: 1) Reorient the antenna of the radio/television,
2) Connect the AC transformer to a different outlet so the control panel and radio/television are on different branch circuits,
3) Relocate the control panel with respect to the radio/television.
If necessary, the installer should consult an experienced radio/television technician for additional suggestions, or send for the
“Interference Handbook” prepared by the Federal Com munications Commission. This booklet is available from the U .S.
Government Printing Office, W ashington D .C. 20402, stock no. 004-000-00450-7.
With a D279A, you can arm and disarm a single zone or point of a Bosch Computer Systems Control/Communicator panel
separately from the rest of the system. The Independent Zone Control (IZC) features a user-programmable four-digit
passcode for arming and disarming, and a built-in panic function. Entry and exit delay times allow you to locate the D279A
Command Center inside the protected area. If you program the D7112, D8112, D9112, D9112B, D7212B and 9000 Series for
opening and closing reports, the D279A can initiate opening and closing reports by zone or point. A 10-wire cable is shipped
with the D279A for interfacing the Independent Zone Control with the panel (4-wires), protective loops (3-wires) and
onboard relay (3-wires).
The D279A is not supervised from the panel: UL Listed applications require arming device supervision. Use the D268/D269
Independent Zone Control to meet the UL requirement for arming device supervision.

You can mount the D279A directly onto a wall, install it in a flush-mount unit, or attach it to a D55 Desk Stand (see the
special installation instruction sheet that comes with each item).
Do not mount the D279A in a location exposed to direct sunlight. Direct sunlight makes the LEDs less visible, and
intense heat can damage the D279A enclosure and electrical components.
Wiring between the D279A and the panel is not supervised: The wiring between the D279A and the panel is not supervised for
trouble conditions. Wiring between the D279A and remote sensing devices is supervised with end-of-line resistors.
3.1Connecting the D279A to the Panel
1.Remove the front cover from the enclosure base (see Figure 1). Use a small flat-blade screwdriver to gently
push the two bottom cover tabs back. As the tabs are pushed back, lift the bottom of the cover away from the

2.Connect the D279A to the panel and protective zones or points as shown in Figure 2 on page 9.
3.Route the 10-wire color-coded cable through the opening in the back of the enclosure base. Rotate the
conductor so that the red wire (PIN 1) is pointing toward the bottom of the keypad and the orange wire
(PIN 10) is pointing toward the top. Plug the connector into the back of the enclosure.
4.Place the enclosure base on the wall in the desired location, and mark the locations of the mounting holes. (The
base can be mounted to a single-gang wall box. The two mounting screw holes in the base of the D279A are
positioned for standard single-gang compatibility.) Secure the enclosure base to the wall or gang box.
5.Push each key on the keypad towards the top of the enclosure to ensure proper mating with the openings in the
top cover.
6.Align the top two tabs of the enclosure cover with the top two tab slots in the enclosure base. Slide the top of
the cover into the base. Gently push the bottom of the cover down on the base until it snaps into place.
7.Program the passcode (see Section 5.1 U ser Passcode on page 13).
- Install a 1 kΩ EOL beyond the last sensor of both the Delayed and Instant loops to provide a
reference for supervision.
- No terminating resistor is needed on the Burglary (green wire) or Panic (yellow wire) outputs to
the panel.
- If the Panic (yellow wire) and Burglary (green wire) outputs are connected to the same zone or
point, place the J4 jumper on the bottom two pins (see Figure 3 on page 13).
- If the Panic (yellow wire) outputs from several Independent Zone Controls are connected to the
same zone or point, place the J4 jumper on the bottom two pins (see Figure 3) on all but one
D279A.
- Burglary (green wire) and panic (yellow wire) outputs: You cannot connect D279A Burglary and
Panic outputs to the D6112 or D4112 power ed loop inputs. P owered loop inputs are D6112
T erminals 16, 17, 18, and 19; D4112 T erminals 16 and 17; and D7112 Terminals 23 and 24.
3.2Connecting the D279A to the D55 Desk Stand
The wiring cable (with modular plug) that is included with the Desk Stand is not compatible with the D279A. T o install a
D279A onto a D55 Desk Stand:
1.Remov e the cover as described previously .
2.Plug the 10-wire cable into the D279A.
3.Route the cable through the hole in the desk stand.
4.Screw the base to the Desk Stand, and replace the cov er .
T o disc onnect the D279A, reverse this pr ocedure. The D279A cable plug cannot be rem oved through the Desk Stand hole.
The D279A branches one zone or point of the panel into two separate loops: one delayed and one instant. Sensors can be
wired to these loops in series (normally closed), or in parallel (normally open), or both. The loops are supervised by a 1 kΩ
end-of-line resistor .
4.2Delayed Loop
Faulting the delayed loop while the D279A is armed starts the 30-second entry delay time on both loops. Allowing the entry
delay time to expire without disarming triggers an alarm, even if both loops are restored. Exit time is provided when arming.
4.3Instant Loop
Faulting the instant loop while the D279A is armed causes an immediate alarm. No entry time is provided unless the delay
loop is faulted first. An entry delay time will be provided if both the instant and delayed loops are faulted at the end of the
exit delay period. Exit time is provided when arming.
4.4Restorals
When both the delayed and instant loops return to normal after an alarm, the D279A is ready to detect another alarm. When
one loop is faulted, a fault on the other loop cannot signal a new alarm to the panel. The restoral to the panel occurs
3 seconds after both loops are restored.
4.5Entry/Exit Delay
Both loops must be normal before the D279A can be armed. When you enter your passcode, an exit delay of 60 seconds is
provided before the unit arms. An entry delay time will be provided if both the instant and delayed loops are faulted at the
end of the exit delay period. When the IZC (Independent Zone Control) is armed, faulting the delayed loop starts an entry
delay of 30 seconds. The D279A must be disarmed during this entry time to prevent an alarm. Once entry or exit delay starts,
both loops are delayed.
4.6Arming and Disarming
Entering the passcode arms and disarms the D279A.
4.7Burglary Alarm Output
Opening or shorting the delayed or instant loop while the D279A is armed causes the output (green wire) to short the panel
zone (after entry delay on delayed loop) or point for a minimum of 3 seconds.
4.8Panic Alarm Function
Simultaneously pressing both asterisk [*] buttons shorts the Panic output (yellow wire) and initiates an alarm. Panic
outputs from several D279A Independent Zone Controls can be connected to the same zone or point. If you do this, place
the J4 jumper on the bottom two pins (see Figure 2 on page 9). The Panic output can be connected to the same zone or
point as the burglary alarm output, but if you do this, the Central Station will not be able to distinguish between panic and
burglary alarms. It is recommended that you NOT wire panic and burglary alarm outputs together to zones or points
programmed for opening and closing reports.
4.9Relay Output
A Form “C” relay (with normally open and normally closed contacts) is provided for connection to an optional
annunciation device, such as a bell or light. An external supply may be required to power this optional annunciation device.
The relay activates when the D279A goes into alarm. It resets when the D279A is disarmed.
Panic [*] buttons: Pr essing the P anic [*] bu tto ns does NOT activate the rela y.
4.10Delayed LED
This green LED lights when the delayed loop is normal. It is not affected by armed status.
4.11Instant LED
This green LED lights when the instant loop is normal. It is not affected by armed status.
This red LED is off while the Independent Zone Control is disarmed. It blinks after you enter your passcode to indicate exit
time in progress, and remains lighted while the system is armed. It is not affected by alarms.
4.13Buzzer
During entry delay, the buzzer sounds ste adily until an alarm occurs or the D279A is disarmed. If you press a numbered key
while the D279A is disarmed and a loop is faulted, the buzzer indicates that the D279A is not ready to arm. The D279A can
only be armed if both loops are normal.
4.14Lit Keys
The D279A keys light during the entry delay period, and when you press any k ey .
The D279A Independent Zone Control comes programmed with a standard passcode of 1234. Once the unit is installed and
power connected, you can change these numbers to the desired four digit passcode.

Tip
Default passcode procedure:
5.1.2Programming or Changing the Passcode
A four digit passcode is used to arm
and disarm the D279A. This code can
be changed only by first knowing the
existing (old) passcode. Change the
passcode only while the D279A is
DISARMED, and BOTH protective
loops are normal. If you make a
mistake while programming, restart
the procedure from Step 2. If
programming is not completed in 60
seconds, the Independent Zone
Control reverts to the old passcode. As
shipped, the J3 jumper plug is placed
across the top two pins, which enables
passcode change (see Figure 3). The
passcode change feature is disabled
when the jumper plug is placed across
the bottom two pins.
Note:Do not program the same digit twice in a row (4556), or program the first and last digit the same (4564). Do not use

Programming
If the standard passcode is recovered while the D279A is armed, an alarm will be generated at the main panel.
1.Connect jumper J3 across the top two pins.
2.Press the [BLANK] key once.
3.Press the following key sequence: [BLANK], [2], [7], [9] (mastercode).
4.Repeat Step #3.
5.The buzzer sounds a beep for 3 seconds to indicate default passcode success.
6.Arm and disarm the zone control to test the default passcode 1234.
1.Connect jumper J3 across the top two pins.
2.Press the [BLANK] key once.
3.Enter the old passcode once ([1], [2], [3], [4]).
4.Enter the new four digit passcode twice.
the [BLANK] key for any digits in the passcode.
5.Arm and disarm the D279A to test the new passcode.
T o prevent further use of this feature, place jumper J3 across the bottom two pins (see Figure 3).
The D279A controls arming/disarming and entry/exit delay for the zone input to which it is connected. Independently
controlled zones use distinctive zone codes that do not follow typical zone code programming rules. The first two digits of
the zone code follow Special Zone Code programming. The last two digits follow standard programming parameters as
detailed in the Zone Code Index of the 8112:MAIN Program Entry Guide. (See the 8112:MAIN Program Entry Guide
[P/N: 74-03762-000]) for complete Independent Zone Control zone code pr ogramming details.) Refer to Table 3.
5.2.1Supervised Independent Zone Controls (Opening and Closing Reports)
T o supervise the IZC, program the zone code with 3 in the first digit position and 2 in the second digit position.
The 3 2 - - code is a Special Zone Code used by the D8112 to identify a supervised D279A zone. To enable opening and
closing reports from the zone controlled by the D279A, cut the jumper (a violet colored jumper , see Ta ble 3) located on the
D279A. The D279A burglary output will go from open to normal (1K) when the control is armed (closed).
Opening and closing reports by zone: When using the D279A to send opening and closing reports by zone, do not use the
same number for the D279A zone number as you do for the passcode ID or the reporting number (see 8112:MAIN Program
Entry Guide [P/N: 74-03762-000] Section 8.0Arm/Disarm Supervision Reports for passcode ID reporting numbers).
Example: If the D279A is connected to zone 8, DO NOT USE passcode 8 or COMEX group 8.
5.2.2Non-Supervised Independent Zone Controls (No Opening and Closing Reports)
For a non-supervised IZC, program the zone code with 3 in the first digit position and 4 in the second digit position. The
3 4 - - code is a Special Zone Code used by the D8112 to identify a non-supervised D279A zone. When the zone code
begins with 3 4, opening and closing reports are not transmitted from the zone controlled by the D279A.
5.2.3Priority Zone Functions
Programming the D279A as a priority zone enables
two valuable functions. When the zone code for the
D279A is programmed with a 3, 4, 7, or 8 in the
fourth digit position, the IZC zone must be armed
before the system can be master armed. How ever,
once the D8112 is armed, the D279A may be armed
and disarmed. In addition, priority zone
programming provides for an arm/disarm status
display at the command center for the IZC zone.
Pressing any key displays the disarmed priority zone
as a faulted zone. Cut jumper J5 to enable the
priority zone feature (J5 is a violet colored jumper,
see Figure 3 on page 13.
Some standard priority sub-zone codes are shown
below:

silences only those alarms initiated by the D279A Panic Alarm
Output, unless fire and burglary inputs are connected to the
same zone.
The bell time restarts with every new trip on the zone input.
The D279A cannot deactivate the Silent Alarm Output (D8112
Terminal 8) if the zone is programmed “Silent.”
The D8112 can be programmed to sound an audible alarm when the D279A is tripped while armed. The D8112 must be
programmed with a bell time and the D8112 zone code must be programmed for audible alarms.
5.3Programming the D7112 Panel Point
The D279A controls arming/disarming and entry/exit delay for the point to which it is connected.
5.3.1Supervised Independent Zone Controls (Opening and Closing Reports)
To supervise the IZC, set the point code to 70000. To enable opening and closing reports from the zone contr olled by the
D279A, cut the jumper labeled J5 OPEN/CLOSE (a violet colored jumper, see Figure 3 on page 13) located on the D279A. The
D279A sounds audible alarms when the 70000 point code is used.
Point closing reports are sent when the D279A begins exit delay .
5.4Programming the D6112 and D4112 Panel Protective Zone
The D279A controls arming/disarming and entry/exit delay for the zone input to which it is connected. The D279A cannot be
used to generate opening and closing reports, or silence the bell (through the software) with a D4112 or D6112. See the D4112Installation and Programming Manual (P/N: 73-05365-002) or the 6112:MAIN Program Entry Guide (P/N: 74-04367-000) for
complete zone code programming details.
J5 Jumper: For normal operation with the D4112 or D6112, do NOT cut jumper J5. Howev er, if you want to display the
D279A armed or disarmed status at the D4112 or D6112 command center , or if you want to put the D279A on a priority
zone, cut Jumper J5.
Some standard sub-control zone codes are shown below:
01150 24 hour zone, trouble on open, instant alarm on short, steady bell on alarm, restoral reports
04110 24 hour zone, instant alarm on short, no trouble conditions, steady bell on alarm
040024 hour zone, instant alarm on short, no trouble conditions, steady bell on alarm, local zone
04150 24 hour zone, instant alarm on short, no trouble conditions, steady bell on aarlm, restoral reports
Using the 01- - - zone code: The 01- - - code only supervises the protective zone wire between the D279A and
the D4112/D6112. It is recomm ended that you DO NOT cut jumper J5 when using this code. I f you cut the jumper, the
D279A sends a trouble report when disarming, and a restoral report when arming.
5.4.1Audible Alarms
The D4112 and D6112 can be programmed to sound an audible alarm when the D279A is tripped while armed. The D4112
or D6112 must be programmed with a bell time and the zone code must be programmed for audible alarms.
5.5Programming the D9112B for the D279A
The D279A can be used in one of two ways with the D9112B: to control an input point or as a keyswitch.
5.5.1Using the D279A to Control an Input Point
The D279A controls arming/disarming and entry/exit delay for the point input it is connected to. If the J5 jumper is cut, point
opening and closing reports may also be sent. In this configuration, how ever , bell control fr om the D279A is not available. If
the D279A is tripped into an alarm condition and is programmed to sound the bell, you must silence the alarm bell using the
command center it is assigned to . You can also use the D279A's onboard Form “C” relay to provide a bell output and thus
allow bell control from the D279A. You ma y use Po int Index #31 from the default Program Record Sheet for the D279A for
this application.
Point closing reports are sent when the D279A begins exit delay .
The D279A can also be used to arm and disarm an individual area. When using it in this configuration, the D279A should be
the only point in the area. The scope of the command center should be programmed to include the D279A’s area (either
Account Wide or Panel Wide scope). Cut the J5 jumper on the D279A to send Area Opening and Closing reports and to
provide bell control from the D279A. Assign a passcode to the D279A’ s area with an authority level for which no functions
are enabled. This allows you to silenc e the bell only in the area in which the passcode is assigned. You may use P oint Index
#28 from the default Program Record Sheet with one modification: program the point response 2 instead of 1.

Note
Make sure that the Exit Delay Time programmed in Area W ide P arameters is less than 60 seconds when using a
D279A.
5.6Programming the 9000 Series Panels for the D279A
If programming the D279A with 9000 Series panels, you can use Point Index 17 (O/C non-priority) or Point Index 18 (O/C
priority) to program points for use with the D279A. Cut the J5 jumper on the D279A to send Point Opening and Point
Closing reports. If the D279A's jumper is not cut, then no open or close reports are sent regardless of the panel
programming.
Point closing reports are sent when the D279A begins exit delay .
5.6.1Assigning the D279A to a Point with Index 17
The Point Response must be programmed as 1 (one). Points assigned to P o int Index 17 will respond as follows:
