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."

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.

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.
