Areas and Accounts
The D7212 supports up to eight separate areas. You can assign all points to a single area
or spread them out over up to eight areas.
You arm and disarm the D7212 panel by area. You can arm and disarm several areas with
one menu function. You can also assign a passcode an authority level that allows a user
to arm an area from a remote command center in another area. Assigning each area its
ownaccount numbercreates eightseparate accounts in one D7212panel. Assigningthe
same account number to different areas, groups them together in a single account.
Area options include: exit tone and delay, separate fire and burglary outputs, and multiple
openingandclosingwindows.
Communicator
TheRadionicsD7212Control/Communicatorpanelusesabuilt-indigitalcommunicatorto
send reports to the receiver. The panel transmits reports in either the Modem II or BFSK
format. Your D6500 receiver's MPU and line cards must have software revision 6.00 (or
greater)installed toaccept ModemII reports from the D7212.Power yourreceiver down
and up to print the software revision numbers.
The D7212 connects to an RJ31X jack for phone line seizure. Connection to the RJ31X
complieswith FCCregulations for usingthe publictelephone network.You can programthe
paneltodirect reports tofourseparate phone numbers.AddingtheD128 Dual PhoneLine
Switcher module allows you to connect and supervise a second phone line.
D1255 Alpha III Command Center
TheD1255 AlphaIII CommandCenter offerscomplete systemcontrol andannunciation.
TheD1255features an illuminatedkeypad,a16-character English languagedisplay,anda
built-in speaker that offers several distinct warning tones. Switches on the D1255 assign
an address (1 to 8) to the command center. You assign addresses to areas in the
CommandCenterAssignmentssection of theprogram.
You can connect a maximum of 32 command centers to the D7212. The available power,
number of supervised command centers, and number of areas you intend to use, affect the
total number of command centers you can connect to the D7212.
The D7212 can supervise up to 8 command centers. The panel transmits a serial device
trouble report, SDI FAILURE in the Modem II format orTROUBLE ZN D in the BFSK
format, if it loses communication with a supervised command center. You can add more
command centers but only eight can be supervised. See Command Center in the D7212
ProgramEntryGuide(74-06915-000) forcompletedetailsoncommandcenteroptions.
Keyswitch
You can arm and disarm any of the eight available areas with maintained or momentary
closure devices such as keyswitches. Keyswitches connect to points. Point programming
determines which area a keyswitch controls. See Options in the Point Index Parameters
moduleofthe D7212ProgramEntryGuide (74-06915-000) .

Event Memory
The D7212 uses event memory to store events for each area. You can view the events for
anarea at aD1255 Command Centerassignedto thearea.The D7212 panelclears the
events for an area from event memory and starts storing new events when you master arm
thearea.
Event Log
The D7212 stores up to 500 events and event modifiers from all areas in it's event log.
Event modifiers add information about an event to the log. Some events are always
followed by a modifier. For example, the D7212 adds at least two items to the log each
time you arm or disarm an area, the open (or close) event and an event modifier showing
the previous arming state.
All events and their modifiers are stored even if the D7212 does not send a report for them.
You can view the log at a D1255 Command Center, print it locally using the D9131 Parallel
Printer Interface and a parallel printer, or upload it to a D5300 Remote Account Manager II
(RAM II).
See S- View Log in the Security System User's Guide (71-06141-000) for a complete
listing of log events and event modifiers.
EMI/Lightning Transient Protection
The D7212 maintains the Radionics high level of quality and field dependability. Its design
significantlyreduceselectromagneticinterferenceandmalfunctiongenerallycausedby
lightning.

PremisesWiring
Run the necessary wiring throughout the premises and pull the wires into the enclosure.
EMI (Electro Magnetic Interference) may cause problems: EMI may occur if you install
the D7212 system or run system wires near the following:
• Computernetworksystem
• Electrical lines, fluorescent fixtures or telephone cabling
• Hamradio transmittersite
• Heavymachineryandmotors
• Highvoltageelectricalequipmentortransformers
• PBX telephone system
• Public service (police, fire departments, etc.) using radio communications
• Radio station transmitter site, or other broadcast station equipment
• Weldingshop
If you think that EMI may be a problem, use shielded cable. The drain wire for the shielded
cable must have continuity from terminal 10 on the D7212 to the end of the wire run. If
continuity is not maintained, the shielded cable may aggravate potential noise problems
ratherthaneliminatethem.
Connectingthe drain wireto ground atother than terminal10 may alsoproduce problems.
If you cut the drain wire to install devices be certain to splice it together. Solder and tape
all splices.
Installing the D7212 Assembly
1. Place the D7212 assembly over the inside back of the enclosure, aligning the large
rectangular openings of the mounting skirt with the mounting hooks of the enclosure.
Slide the D7212 down so it hangs on the hooks. See Figure 2.
2. Remove the tape from the #6x1/4" screw in the mounting tab on the D7212 assembly.
The screw passes through the mounting tab and into the skirt mounting hole in the
enclosure. Tighten the screw to secure the D7212 assembly in the enclosure.
3. Connect earthgroundto thepanelbefore makinganyother connections.See
ConnectingEarthGround below .
Connecting Earth Ground Terminal 10
To help prevent damage from electrostatic charges or other transient electrical surges,
connect the D7212 to earth ground at terminal 10 before making any other connections. A

Existing reports transmitted with Reset Pin locked down: Any reports that are in the
panel’s report buffer when you lock down the Reset Pin, will be transmitted. However, no
new reports can be created with the pin locked down.
To prevent buffered reports from being transmitted, momentarily close the Reset Pin, wait
for the buzzer to stop sounding, and then lock the pin down to prevent new reports from
beinggenerated.
Locking Reset Speeds Programming: If you have supervised command centers or other
supervised devices connected to the Data Bus (terminals 30 and 31), locking the Reset
Pinwillspeed communicationbetweenthepanel andtheD5200.
On-board relays (terminals 6, 7, and 8) and off-board relays, deactivate when the panel is
reset. There is power at terminal 8 when the relay is deactivated. Activation interrupts
power at that terminal. The relays remain deactivated while the Reset Pin is locked in the
disableposition.
You can program the panel while it is locked in the disable position with either the D5200 or
D5300 (RAM II) programmers. If you place the reset pin in the disable position with one or
more areas disarmed, there must be an entry in the AnswerDisarmed
program item to use RAM II.
If you place the reset pin in the

Finishing the Installation
Earth ground and reset pin first: Make the earth ground connection to terminal 10 and
lock the reset pin in the closed position if you haven’t already done so.
Charge the Battery as You Finish
Connect the battery and then the transformer so that the panel can charge the battery as
you finish the installation. See the Power Supply section for instructions.
On-board Buzzer Sounds at Power Up and Reset: The D7212 performs a series of self
diagnostic tests of its hardware, software, and program at power up and at reset. The
buzzer on the D7212 sounds during the tests. They take about 10 seconds to complete.
If the panel fails any of the tests, the buzzer continues sounding and a system trouble
message appears at the command centers. See Self Diagnostics in the Trouble Shooting
section for a description of each system trouble message.
Touch Terminal 10 first: If the on-board buzzer sounds briefly when you touch the panel,
you're discharging any static charge you may be carrying to the panel. The panel may
generateWATCHDOGRESET and/or PARAMFAILevents.See the TroubleShooting
section for a description of these events. Always touch terminal 10, the panel's earth
groundconnection, beforebeginningworkonthepanel.

Power Supply
Primary Power Terminals 1 2
Primary (AC) Power Circuit
A 16.5 VAC, 40 VA internally fused transformer (Radionics model D1640) is the primary
power source for the D7212. The AC power circuit provides 1.9 Amps of rectified AC
power. The panel reserves 500 mA of this power for internal operations leaving 1.4 Amps
forpowereddevices.
Transient suppressors and spark gaps protect the circuit from power surges. This
protection relies on the ground connection at terminal 10. Make sure you connect terminal
10 to a proper ground. See Connecting Earth Ground in the Installation section .
ACPowerFailure
The D7212 indicates an AC power failure when the power at terminals 1 and 2 is missing.
The AC Fail Time program item sets the number of seconds that AC must be missing
beforethe panel acknowledgesthe failure andthe number ofseconds after thepower
returnsbeforethepanelacknowledgestherestoralofpower.
You can program AC Fail Time from 1 to 90 seconds. The Radionics default sets AC Fail
Time at 10 seconds.
Installing the Transformer
Do not short the terminals of the transformer: Shortingtheterminals opens theinternal
fuse causing permanent failure. Connect the transformer to terminals 1 and 2 of the panel
beforepluggingit intothepowersource.
Use 18 AWG (minimum) wire to connect the transformer to the panel. Wire length should
be kept as short as possible. Maximum length is 50 feet.
Connect the battery and then plug in the transformer: Radionicsrecommends that you
always connect the battery first and then plug in the transformer. Instructions for Installing
the Battery appear on the next page.
Only plug the transformer into an unswitched, 120 VAC, 60 Hz power outlet. Secure the
transformer to the outlet with the screw provided.
Never sharethetransformerwith other equipment: ForeigngroundsontheACinput

Secondary Power Terminals 45
Secondary (DC) Power
A12V,7Ahsealedlead-acidrechargeablebattery(RadionicsD126) supplies secondary
powerfor auxiliaryand alarmoutputs, and powers the systemduring interruptionsin
primary(AC)power.
Lead Acid Batteries ONLY: TheD7212chargingcircuit is onlycalibratedforlead-acid
batteries. Do not use gel-cell or nicad batteries.
Extra Batteries Increase Back-up Time: Toincreasebatteryback-up time, connecta
second 12V, 7 Ah battery in parallel to the first battery to form a 12V, 14 Ah battery. Use a
D122Dual BatteryHarness toensure properand safeconnection. Youcan usethe D8132
Battery Charger Module to connect two additional batteries for a total of four. See the
D7212 Standby Battery and Current Rating Chart in this manual for battery standby time
calculations.
Installing the Battery
Place the battery upright in the base of the enclosure. Locate the red and black leads
supplied in the literature pack. Connect the black battery lead to terminal 4, and then to the
negative (-) side of the battery. Connect the red battery lead to terminal 5, and then to the
positive (+) side of the battery.
Warning, High Current Arcs Possible: The positive(red) batterylead and Terminal 5
can create high current arcs if shorted to other terminals or the enclosure. Use caution
when working with the positive lead and terminal 5. Always disconnect the positive (red)
lead from the battery before removing it from terminal 5.
Replacement
Radionicsrecommends batteryreplacement every3 to5 yearsunder normaluse.
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
prematurebatteryfailure.
D8132boosts battery backup: AddingaD8132BatteryChargerModulesupports
additional batteries of up to 36 Ah capacity if required.
Warning: The transformers for the D7212 and any D8132 modules connected to it must be
powered from the same 120 VAC circuit. The D7212 supervises AC power by monitoring
the power from the transformer connected to terminals 1 and 2. It cannot supervise the AC
power for D8132 modules if their transformers are not plugged into the same AC circuit as
thetransformerfor the panel.
Battery Supervision
When the battery voltage drops to 13.8 VDC, the yellow Charging Status LED lights. When
the battery drops to 12.1 VDC the red Low Battery LED lights and the panel, if programmed
for power supervision, transmits a BATTERY LOW report in the Modem II transmission
format. It transmits a TROUBLE ZN 9 report in the BFSK format.
If the battery is missing or shorted, the red Low Battery LED flashes at the same rate as
thegreen OperationMonitor LED.If the panel is programmedfor powersupervision, it
transmits a BATTERY MISSING report in the Modem II transmission format, or TROUBLE
ZN 9 report in the BFSK format.

Battery Supervision (Continued)
When battery voltage returns to 13.7 VDC the Low Battery LED goes out. If the panel is
programmed for power supervision, it transmits aBATTERY RESTORAL report in the
Modem II transmission format or RESTORAL ZN 9 report in the BFSK format. At 13.9
VDC the Charging Status LED goes out.
Investigate low battery reports right away : If primary (AC) power is off and the
dischargecontinues,thepanelbecomesinoperativewhen the battery voltagedropsbelow
10.2VDC.
Battery Charging Circuit
FloatCharge
The float voltage for the battery charging circuit is 13.9 VDC at a maximum current of 1.4
Amps. Deduct any continuous load for devices connected to the panel from 1.4 Amps to
find the actual current available for charging.
Load Shed Relay protects battery: Duringan AC powerloss the batterysupplies all
power to the security system. If the battery voltage falls below 10.2 volts during an AC
power loss, a “load shed” relay isolates the battery from the panel and disables the panel.
Loadshedprotects thebatteryfrombeing damagedbydeepdischarge. WhenACpower
restores, the load shed relay resets and battery voltage is again available.
Reset or power down required for shorted battery: Ifthe D7212determines the battery
is shorted, it uses the load shed relay to disconnect the battery. You must reset or power
down the panel after correcting the problem to reset the load shed relay and reconnect the
battery.
Reset the panel by momentarily placing the reset pin in the disable position. See Figure 3.
The red Low Battery LED continues to flash until you reset the panel.
A shorted battery condition is created either by a shorted cell inside the battery or by a
short on terminals 4 and 5. A shorted battery may generate WATCHDOG RESET reports.
