label contains, among other information, the FCC
registration number and ringer equivalence number
(REN).
Radionics registered the D2112 Control/
Communicator for connection to the public telephone
network using an RJ38X or RJ31X jack.
Use the ringer equivalence number (REN) to
determine the number of devices you can connect to
the telephone line. Excessive RENs on the telephone
line may result in devices not ringing in response to
an incoming call. In most, but not all areas, the sum
of the RENs should not exceed five (5). Contact the
telephone company to determine the maximum REN
for the calling area.
If the D2112 Control/Communicator causes harm to
the telephone network, the telephone company will
notify you in advance. If advance notice isn’t
practical, the telephone company will notify the
customer as soon as possible. Also, you will be
advised of your right to file a complaint with the FCC
if you believe it is necessary.
The telephone company may make changes in its
facilities, equipment, operations, or procedures that
could affect the operation of the D2112. If this

Getting Started
Before You Begin
Radionics recommends you review this manual
before you begin the installation to determine the
hardware and wiring requirements for the features
you want to use.
Have the following additional documents handy as
you read through the manual:
•
D2112/D2112E Program Record Sheet

Mount the Enclosure
Lift the bottom of the enclosure cover and remove it
from the base. See Figure 1.
Mount the base in the desired location. Leave a 2"
clearance at the top of enclosure so that you can
easily install the cover.
Run the Premises Wiring
Run the necessary wiring throughout the premises
and pull the wires into the enclosure. Do not make
any connections yet.
Wire Length
The length of the wire run for points is limited only by
the resistance on the loop and potential EMI
(Electro-Magnetic Interference) problems.
On the D2112, wire resistance on the Point 1 sensor
loop must be less than 50Ω. Measure the wire
resistance before installing smoke detectors. Short
the end-of-line resistor before metering the wire.
Resistance on the sensor loops for Points 2 to 8 (1
to 6 on D2112E) must be less than 100Ω with the
end of line resistor shorted and the detection devices
connected.
Maximum wire length for the transformer is 50 feet
(18 AWG, stranded).
Maximum wire length for all keypads combined is
500 feet (22 AWG).
EMI (Electro Magnetic Interference)
AC wiring can induce EMI (both noise and low level
voltage) into adjacent wiring. Run phone and sensor
loop wiring away from AC conductors, including the
transformer wire. Run keypad wiring away from AC
and phone wiring.
EMI may also occur if you install the panel or run
system wires near the following:
• Computer network system
• Fluorescent fixtures
• Telephone cabling
• Ham radio transmitter site
• Heavy machinery and motors
• High voltage electrical equipment
• PBX telephone system
• Public service (police, fire departments, etc.)
using radio communications
• Radio station transmitter site, or other broadcast station equipment
• Welding shop
If you think that EMI may be a problem, use shielded
cable. The drain wire for the shielded cable must
have continuity from terminal 3 on the panel to the
end of the wire run.
If continuity is not maintained, the shielded cable
may aggravate potential noise problems rather than
eliminate them. If you cut the drain wire to install
devices be certain to splice it together. Solder and
tape all splices.
Cover
Base
Swing cover out from
base at bottom. Lift
cover clear of base.
74-07111-000-D 1/96
Connecting the drain wire to ground at other than
terminal 3 may also produce problems.
Mount base to wall.
Leave at least 2 inches
clearance at top to install
and remover cover.

Connect Earth Ground
Terminal 3
To help prevent damage from electrostatic charges
or other transient electrical surges, connect the
panel to earth ground at terminal 3 before making
any other connections.
A grounding rod or cold water pipe are
recommended earth ground references.
Radionics does not recommend a telephone or
electrical ground for the earth ground connection.
Use 18 AWG wire maximum under the terminal. Use
a lug or splice for larger wire.
Do not connect any other panel terminals to earth
ground. The panels common terminals and terminal
3, earth ground, are electrically isolated.
Charge the Battery as You Work
Lock the Standby Switch
Locking the pin in the standby position allows you to
charge the battery as you install the detection
devices and keypads. Lock the pin down now. See
Figure 2.
With the Standby Switch locked down, the panel
deactivates the external relay outputs, suppresses
reports, and disables all arming functions.
Lock the Standby Switch down to program the
panel locally, from the keypad or the D5200.
Releasing the Standby Switch from the closed
position resets the panel. The panel resets all its
timers and counters, and clears all buffers.
Transformer
Terminals 1 and 2
Connect the transformer to terminals 1 and 2 on the
panel before plugging it into the power source.
Use 18 AWG wire to connect the transformer to the
panel. Wire length should be kept as short as
possible. Maximum length is 50 feet.
Never share the transformer with other
equipment:
Foreign grounds on the AC input
damage the panel's power circuit.
Battery
Terminals 4 and 5
Place the battery upright in the base of the
enclosure. First connect the bare end of the black
battery lead to terminal 5 on the panel. Then plug
the other end to the negative (-) side of the battery.
Next connect the bare end of the red battery lead to
terminal 4 on the panel. Then plug the other end to
the positive (+) side of the battery.

Number of Sensors
When using the D2112's Point 1 as a fire point, the
number of devices you can connect to it's sensor
loop is limited. See
Page 10.
The number of sensors you can connect to the
sensor loops for points 2 to 8 (1 to 6 on D2112E) is
limited only by the resistance on the loop.
Resistance must be less than 100Ω with the
detection devices connected.

2. Switch the meter to measure Ohms.
3. Attach the meter leads to each side of the fuse.
4. If the meter does not change when you
connect the leads to the fuse, the fuse is open
(blown). Replace the blown fuse with a 5 mm x
20 mm, 2 Amp Fast Blow fuse.
5. If the meter measures 0 Ohms, the fuse is
closed (normal), and does not need to be
replaced.

To prevent jamming of reports, wire the RJ31X jack
before the in-house phone system to support line
seizure. See Figure 7. Line seizure provides for a
temporary interruption of normal phone usage while
the communicator transmits data.
Unlock the Standby Switch
When you're finished programming move the
Standby Switch to the normal position. See Figure 9.
The panel sends a RE-BOOT report to the receiver
and the panel returns to the disarmed state. If you
programmed for test reports and left the hours and
minutes to next report prompts at 0 (zero), the panel
sends a test report with the RE-BOOT report.
After installation, confirm that the panel seizes the
line, acquires dial tone, reports correctly to the

Detailed Panel Description
Primary (AC) Power Circuit
A 16.5 VAC, 25VA transformer (Radionics model
D1625) is the primary power source for the panel.
The AC power circuit provides 1.0 Amps of rectified
DC power. The panel reserves 140mA of this power
for internal operations and 350mA for continuously
powered devices. Under alarm conditions 860mA of
power is available for continuously powered and
alarm indicating devices combined.
Battery Replacement
Radionics recommends battery replacement every
three to five years under normal use. Exceeding the
maximum output ratings, or installing the transformer
in an outlet that is routinely switched off, causes
heavy discharges. Routine heavy discharges can
lead to premature battery failure.
D135A Prevents Deep Discharge:
Battery Cutoff Module protects the battery from deep
discharge during extended power outages. Deep
discharge can cause permanent battery damage.
Battery Supervision
When the battery drops to 12.1 VDC the OK light on
the keypad winks, indicating a trouble condition. The
panel transmits a BATTERY LOW report.
When battery voltage returns to 13.0 VDC and there
is AC power at terminals 1 and 2, the OK LIGHT at
the keypad stays on steady. The panel transmits a
BATTERY RESTORAL report.
Investigate low battery reports right away
If primary (AC) power is off and the discharge
continues, the panel becomes inoperative when the
battery voltage drops below 10.2 VDC.
The D135A Low
:
Transient suppressors and spark gaps protect the
circuit from power surges. This protection relies on
the ground connection at terminal 3. Make sure you
connect terminal 3 to a proper ground.
AC Power Failure
The panel indicates an AC power failure when power
at terminals 1 and 2 is missing for 60 seconds. The
AC Fail Buzz/Rpt AC Fail Buzz/Rpt
response to detected AC failure. The panel indicates
an AC power restoral 60 seconds after power
restores to terminals 1 and 2.
program item sets the panels
Secondary (DC) Power
A 12V, 4.0 Ah sealed lead-acid rechargeable battery
(Radionics D1240) supplies secondary power for
auxiliary and alarm outputs. The battery also powers
the system during interruptions in primary (AC)
power.
Lead Acid Batteries Only: The panel charging
circuit is only calibrated for lead-acid batteries. Do
not use gel-cell or nicad batteries.
Larger Battery Increases Backup Time: To
increase battery backup time, connect a larger
capacity battery, up to 7 Ah (Radionics D126).
Battery Charging Circuit
Float Charge
The float voltage for the battery charging circuit is
13.9 VDC. Deduct any continuous load for devices
connected to the panel from 860mA to find the
maximum current available for charging. At 13.9
VDC the battery is fully charged and is maintained
with a trickle charge of approximately 5mA.

Power Outputs
D2112 Circuit Protection
Two self-resetting protection devices protect the
panel from short circuits on both the auxiliary and
alarm power outputs.
D2112E Circuit Protection
Two fuses protect the panel from short circuits on
both the auxiliary and alarm power outputs.
D2112 bell circuit protection:
power output while the bell is ringing disables the
alarm power output until the output times out or you
perform a panel reset.
Reports
The panel transmits a trouble Point 99 report when
there is a short on the alarm output, terminals 6 and
7, or when the fuse is open. The panel transmits a
trouble Point 98 report when Auxiliary Power,
terminal 9, is shorted, or when the fuse is open.
Extra Power for Keypad or Other Powered
Devices
The D202 Keypad draws 45mA (125mA in alarm).
You may need to add one or more D8132 Battery
Charger/Power Supply Modules for the number of
keypads you want to use. Figure 11 shows the
D8132 powering keypads in a stand-alone
configuration.
For UL certificated accounts use a UL listed power
supply. The D8132 is not UL listed as a stand-alone
power supply.
D2112 and D8132 (or other power supply) must
share COMMON:
Note that Figure 11 shows the
common from the D8132 module connected to both
the keypads' common and the terminal 10 on the
panel.
A short on alarm
A stand-alone power supply powering any device
connected to the panel must also be connected to
terminal 10 on the panel. Do not connect the standalone power supply to earth ground.
Telephone
Dialing Format
You can program the panel to use DTMF or pulse
dialing. See
D2112E Program Entry Guide
Communication Failure
After 5 attempts to reach the receiver (10 attempts if
two phone number are programmed) the panel goes
into communication failure. The panel clears any
reports in its phone buffer. The panel sounds a tone
at the keypad and winks the OK light.
Pressing the Clear key silences the tone. When
communication restores (a report is acknowledged
by the receiver), the OK light restores.
Ground Start
Some telephone systems require a momentary
ground input to initiate dial tone. To interface with a
ground start system, connect a D133 relay as shown
in Figure 12.
