1.4 FCC 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 Communications Commission. This booklet is
available from the U.S. Government Printing Office, Washington D.C. 20402, stock no. 004-000-00450-7.

D279A
Overview
2.0 Overview
With a D279A, you can arm and disarm a single zone or point of a Radionics Control/Communicator panel
separately from the rest of the system. The Independent Zone Control (IZC) features a user-programmable 4-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, or D9112 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.

Installation
3.0 Installation
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.

1. Remove the front cover from the enclosure base (see Figure 1 above). 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 base. Remove the cover.

2. Connect the D279A to the panel and protective zones or points as shown in Figure 2.
•Install a 1 kWEOL 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 or Panic outputs to the panel.
•If the Panic and Burglary outputs are connected to the same zone or point, place the J4 jumper on the
bottom two pins (see Figure 3).
•If the Panic 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 and panic outputs: You cannot connect D279A Burglary and Panic outputs to the D6112 or
D4112 powered loop inputs. Powered loop inputs are D6112 Terminals 16, 17, 18, and 19; D4112
Terminals 16 and 17; and D7112 Terminals 23 and 24.
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
User Passcode ).
3.2 Connecting 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. To
install a D279A onto a D55 Desk Stand:
1. Remove 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 cover.
To disconnect the D279A, reverse this procedure. The D279A cable plug cannot be removed through the Desk
Stand hole.
