D268, D269  
Description  
Description  
The D268/269 Independent Zone Control Modules are accessory devices for use with Radionics control/  
communicators. You can use the D268/D269 to arm and disarm a single 1k W zone of a D4112, D6112, or D8112  
or single 1k W point of a D7112 or D9112 Control/Communicator panel. The D268/D269 features a user  
programmable passcode and can initiate Opening/Closing reports by zone or point when the panel is programmed  
for this response. You can install up to four D269 Keypads for each D268 Module with at least one D269 Keypad  
being required. Entry and exit delay times provided by the D268 allow the D269 keypads to be located inside the  
protected area. The operation of the D268 Module is not affected by tampering to the D269 Keypad.  
Operation  
D268 Module Loop Inputs  
The D268 branches a single 1k W zone or point of the panel into two separate loops: one delayed and one instant.  
You can wire sensors to the loops in series (normally closed) or in parallel (normally open). Install a Radionics  
model D105BL 1k W end-of-line resistor, supplied with the module, beyond the last sensor of each loop to  
provide supervision (see Figure 4).  
Delayed Loop  
Faulting the delayed loop while the D268/D269 Independent Zone Control is armed starts the entry delay time on  
both loops. Allowing entry time to expire without disarming triggers an alarm even if both loops are restored. Exit  
time is provided when arming.  
Instant Loop  
Faulting the instant loop while the D268/D269 is armed immediately causes an alarm. No entry time is provided  
unless the delay loop is faulted first. Exit delay time is provided when arming.  
Entry/Exit Delay  
Both loops must be normal before you can arm the D268/D269. Entering the correct passcode provides 60  
seconds of exit time before the unit arms. After arming, faulting the delay loop starts 30 seconds of entry time in  
which the D268/D269 must be disarmed to prevent an alarm. Once entry and exit delay starts both loops are  
delayed.  
Restorals  
The D268 resets automatically when both the delayed and instant loops are normal. However, when one loop is  
faulted, the other cannot signal a new alarm to the panel. Restoral of the zone or point output is delayed three  
seconds after both loops are restored.  
Burglar Alarm Output  
Opening or shorting either of the D268 loops while the zone control is armed causes the output to short the panel  
zone or point for a minimum of three seconds. Each zone or point is supervised with a Radionics model 105BL  
1k W end-of-line resistor.

D268, D269  
Operation  
Operation (continued)  
Open/Close Output  
This output presents an open circuit to the panel when the D268/D269 is disarmed, and a normal circuit when  
the D268/D269 is armed and not in alarm.  
Alarm Output Terminals  
Two form C contacts, each rated at 2 Amps, are provided for an optional alarm device, such as a bell. This relay  
is activated when the D268/D269 goes into alarm, and is reset when the D268/D269 is disarmed. A D136 Relay  
needs to be installed in the D268 for this option.  
D269 Keypad  
Green LED - Loop Status  
The Loop Status LED lights when both the delayed and instant loops are normal. It's switched off when one or  
both loops are faulted. This LED is not affected by armed status.  
Red LED - Armed Status  
The Armed Status LED starts blinking when the correct passcode is entered to indicate exit delay time in  
progress. This LED is on while the D268/D269 is armed. This LED is off while the D268/D269 is disarmed.  
Warning Sounder  
During entry delay, the warning sounder latches on until the D268/D269 is disarmed or an alarm occurs. If a  
numbered key is pressed while the unit is disarmed and has a loop faulted, a warning sound indicates that it's  
not ready to arm.  
Standard Combination  
You enter a four-digit passcode into the D269 Keypad to arm and disarm the D268 zones. The D268 is shipped  
from the factory with a default passcode of 1234 or 2222. Once the unit is installed and power is connected, you  
can change these numbers to a different passcode. This passcode is the same at all D269 Keypads connected  
to that D268.  
Programming  
Programming or Changing the Combination  
You need to install a jumper plug on J1 in the “A “ (COMB CHG) position (see Figure 2) to enable the passcode  
change feature. To prevent further passcode changes, place the jumper plug in the "B" (NO) position.  
You must know the existing (old) passcode before you can change it to a new one. If you do not know the  
passcode, see Recovering the Standard passcode in this manual. If you make a mistake while changing the  
passcode, wait 5 seconds and repeat the procedure. If the procedure is not completed within 60 seconds, the  
keypad reverts to the old passcode.  
Only change the passcode when the keypad is disarmed. Do not program the same digit twice in a row. Do not  
program the first and last digits the same.

Programming  
Figure 2: D268 Module  
Using the D268 Module with the D8112 Control/Communicator  
The D268 controls arming/disarming and entry/exit delay for the zone input to which it is connected. Sub-control  
zones use distinctive zone codes which 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. (See the 8112: MAIN Program Entry Guide, Section 22.4 for complete sub-control zone code  
programming details.)  
Supervised Independent Zone Controls (Opening and Closing Reports)  
As an installation option, the zone output of the D268 (see Figure 4) can be switched open when the D268 is  
disarmed and returned to normal when the sub-control arms. This can be used to generate opening and closing  
reports by zone from a supervised panel. The panel must be programmed for opening/ closing reports.  
When using a D8112, supervised sub-control zone codes must be programmed with a 3 in the first digit position  
and a 2 in the second digit position. The 3 2 _ _ code is a Special Zone Code used by the D8112 to identify a  
supervised sub-control zone. Install jumper plug J2 in the “B” OP/CL position on the D268 Module (see Figure 2)  
to enable opening and closing reports from the zone controlled by the D268.  
Non-Supervised Independent Zone Controls (No Opening and Closing Reports)  
The zone code for a non-supervised, sub-control zone must be programmed 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, sub-control zone. When the zone code begins with 3 4, opening and closing reports are not transmitted  
from the zone controlled by the D268.  
Priority Zone Functions  
Programming the D268 as a priority zone enables two valuable functions. When the zone code for the D268 is  
programmed with a 3, 4, 7, or 8 in the fourth digit position the sub-control zone must be armed before the main  
system can be master armed. In addition, priority zone programming provides for an arm/disarm status display  
on the Command Center for the sub-control zone. If you attempt to arm the system when the D268 is not armed,  
a dash (-) is displayed on the Alpha command center to indicate a fault. Pressing any key displays the disarmed  
priority zone as a faulted zone. Some standard priority sub-control zone codes are shown below:  
3233  
3433  
3273  
Supervised, no restoral reports, steady bell on alarm, Alpha display visible, priority zone.  
Non-supervised, no restoral reports, steady bell on alarm, Alpha display visible, priority zone.  
Supervised, restoral reports, steady bell on alarm, Alpha display visible, priority zone with no swinger  
shunt.

* Bell Control from the D268  
When jumper J2 of the D268 Module is installed in the “B” (OP/CL) position, entering the passcode into the D269  
silences the bell output of the D8112. The D268 silences only those alarms initiated by its zone input to the  
D8112. Bell time restarts with every new trip on the zone input. The D268 cannot deactivate the Silent Alarm Output  
(D8112 terminal 8) if the zone is programmed “Silent”.  
Using the D268/D269 with a D7112 or D9112 Control/Communicator  
The D268 controls arming and disarming, and entry and exit delay times for a single 1kW point. Bell control is not  
available from the D268/D269 on the D7112.  
Supervising the D268 (Opening and Closing Reports)  
The point output of the D268 module can be switched open when the D268 is disarmed, and restored to normal  
when the point arms. This can allow you to send open and closing reports to a receiver. Refer to the D7112 or  
D9112 Program Entry Guide for point code programming options.  
Install a jumper plug on J2 in the "B" OP/CL position on the D268 module to enable opening and closing reports  
from the point controlled by the D268.  
D9112 Control/Communicator Options  
The D268/D269 can control arming/disarming and entry/exit delay for the point input it's connected to. Install a  
jumper plug J2 in the "B" position on the D268 to enable the sending of point openings and closings. In this  
configuration, bell control from the D268 is not available. If the D268 is tripped into alarm and is programmed to  
sound the bell, you must silence the alarm bell at its assigned command center. You can also use the D268's on-  
board Form C relay to provide a bell output and to allow bell control from the D268/D269. You may use Point Index  
#31 from the default Program Record Sheet for the D268/D269 for this application.  
The D268/D269 can also be used to arm and disarm individual areas. When in this configuration, it should be the  
only point in the area. The scope of the command center should be programmed to include the D268/D269's area  
(either Account Wide or Panel Wide scope). Install a jumper plug J2 in the "B" position to enable point opening  
and closing reports and to provide bell control. Assign a passcode wiith an authority level having no functions  
enabled with it. This allows you to silence the bell only in the area where the passcode is assigned. You may use  
Point Index #28 from the default Program Record Sheet, with one exception: program the point response "2"  
instead of "1."

D268, D269  
Installation  
D268 Module Installation  
Mounting the D268  
The D268 Independent Zone Control Module is suitable for installation in a D8103 Enclosure or a D8108A Attack  
Resistant Enclosure. Both enclosures available for UL certified Local and Central Station Grade A or B, and  
Police connected burglar alarm applications. Align the D268 Module with any of the four mounting locations, and  
fasten the module in place with the three mounting screws provided.  
Wiring the D268  
Three wires are used to connect the D268 Module to the panel, +12 VDC, common, and zone or point input.  
These wires are connected to a 10-position terminal block on the D268 Module (see Figure 4).  
The D268 output (terminal 5) can be connected to a 1k W zone or point of a Radionics control/communicator. The  
zone or point input requires only a single wire from the D268 that connects to its positive terminal. No terminating  
resistor is required.  
D268 Protective Zones  
D268 sensor loops function independently, and are similar to the loops on the panel. Each sensor loop is  
supervised with a Radionics model 105BL 1k W end-of-line resistor supplied with the module (see Figure 4).  
Protected wiring (Figure 5) may be required for applications where the D268 sub-zone cable is exposed. You can  
use 22 AWG (minimum) wire in place of the tin copper shield braid (Figure 5:, Note 2), and rigid conduit or  
electrical metallic tubing can be used in place of the PVC tubing (Note 3). All splice boxes must be tampered.  
Dry contact sensing devices may be connected in series (normally-closed) or in parallel (normally open) to each  
sensor loop. Each loop can detect open circuit, closed circuit, and normal circuit conditions. For complete  
information, see Using the D268 Module with the D8112 and Using the D268 with the D7112/D9112 in this  
manual.  
Optional Alarm Device Wiring  
An optional alarm device, such as a bell, can be installed to annunciate alarms associated with the D268/D269.  
Figure 4 shows the wiring of the optional device from the D268 Module to the panel. A Radionics model D136  
Relay must be installed in the K1 socket of the D268 Module (see Figure 2) to operate this optional device. The  
socket is designed so the relay can be inserted in either the top or bottom positions. Insert the relay with the three  
legs facing away from C3. If a fault is detected on a D268 loop, the on board form C relay is activated. The relay  
is latched until you enter the passcode. See the appropriate Operation and Installation Manual for further details  
on the programming and operation of the Alarm Output.  
D268 Jumpers  
The D268 Module contains two movable jumpers. The location of these jumpers is shown in Figure 2. Jumper  
J1 is used to enable and disable the passcode change function from a D269 Keypad. With the jumper plug  
installed in the “A” (COMB CHG) position, you can change the passcode. If the jumper plug is installed in the “B”  
(NO) position, you cannot change the passcode.  
Jumper J2 enables the control/communicator to receive opening and closing reports from the D268. When the  
jumper plug is in the “B” (OP/CL) position, opening and closing reports are sent . When the jumper plug is in the  
“A” (NO) position, opening and closing reports are not sent.  
D268 LED: The red LED on the D268 Module is for manufacturing test purposes only.

D269 Keypad Installation  
The D269 Keypad is shipped with a faceplate, a backbox/circuit assembly, a 4-wire cable, two mounting screws,  
two collapsible clips, and two wall mounting plates. The keypad installs flush to the wall surface, and may be  
installed into a single-gang box, if desired. Do not mount the D269 in a location exposed to direct sunlight, this  
may make the LEDs less visible. Follow the directions below for mounting.  
1. To install the D269 flush with the wall surface, make an opening in the wall 2" wide x 3.25" high.  
2. Route the 4-wire cable through the wiring opening in the backbox, and plug it into the 4-pin connector on the  
circuit board.  
3. If you are installing the D269 into a single-gang wall box, see step 3a. If you are installing it without single-  
gang box, see step 3b.  
3a. Insert the D269 into the wall opening and attach it to single-gang wall box with screws provided.  
Go to step 5.  
3b. Insert screws (#6 x 2" screws supplied with the unit) into mounting holes. Place the wall mounting plate on  
the backbox, aligning it with the screw.  
Slide a collapsible clip over each screw. Tighten each screw until firm. Do NOT tighten screws enough to  
bend collapsible clips.  
4. Insert the D269 assembly into the wall opening. Tighten each screw firmly.  
5. Position the faceplate over the assembly, hook it over the top and gently push the bottom of the plate until it

D268, D269  
Installation  
Wiring the D269 Keypads  
You can wire up to four D269 Keypads in parallel to the D268 Module (see Figure 4). You must install at least one  
D269. A cable with a four pin connector and four wire leads is supplied with each keypad. The furthest D269 can  
be located a maximum of 500 feet away from the panel enclosure. Using a larger gauge wire does NOT increase  
this distance.  
UL certificated installations: UL certifications require a D8108A Attack Resistant Enclosure, and a 1 Amp in-line  
fuse (Radionics model D201, supplied with the D268 Module) on the red power supply wire. Only one fuse is  
required per D268/D269 sub-system.  
D268/D269 Configurations  
You can use the D268 and D269 in several sub-zone applications. Figure 7 shows a typical configuration of the  
D268 and D269 protecting a sub-zone within the main protected premises. You can locate the D269 either inside  
or outside of the protected area. Protected wiring (Figure 5) is not required for this application.  
Figure 7 Independent Zone Control Within Protected Premises  
Figure 8 shows a D269 located outside the main protected premises. As in the previous case, the D269 can be  
located either inside or outside of the protected area. Protected wiring (Figure 5) is required for this application.
