Lead Acid Batteries Only: The panel charging circuit is
only calibrated for lead-acid batteries. Do not use gel-cell or
nicad batteries.
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: The D135A Low 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 keypad indicates a
trouble condition. The panel will transmit a BATTERY LOW
report.
When battery voltage returns to 13.0 VDC and there is AC
power at terminals 1 and 2, the keypad returns to normal
operation. The panel will transmit 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.
If the battery is disconnected, it takes 60 seconds for the
panel to recognize the condition.
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 1.0 A 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 5.0mA.

Fill out the Point Chart
Radionics recommends that you fill out the
Point Chart on
the Installation Label located on the inside of the D2203
Enclosure cover.
You must fill out the point chart if you programmed
Point 1 for Fire with Verification (Digit 1 = 2). See POINT
CODES in the D2212 Program Entry Guide for more
information.
Use the
Program Record Sheet to gather the information you
need to fill out the point chart.
Test the System
After finishing the installation and programming, perform a
complete functional test of the system. Test the panel and all
devices for proper operation. Test after you first program the
panel and after any subsequent programming sessions.
Clear after test: To clear the alarm memory and report
buffer, place the Standby Switch in the closed position for
two seconds and then release it. The panel returns to
service in the disarmed state.
Detailed Panel Description
Primary (AC) Power Circuit
A 16.5 VAC, 40VA transformer (Radionics model D1640) is
the primary power source for the panel.
The AC power circuit provides 1.5 Amps of rectified DC
power. The panel reserves 140mA of this power for internal
operations and 1.0 A for continuously powered devices.
Under alarm conditions, 1.0 A of power is available for
continuously powered and alarm indicating devices
combined.
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
program item sets the panel response to detected
AC failure. The panel indicates an AC power restoral 60
seconds after power restores to terminals 1 and 2.
Secondary (DC) Power
A 12V, 7.0 Ah sealed lead-acid rechargeable battery
(Radionics D126) supplies secondary power for auxiliary and
alarm outputs. The battery also powers the system during
interruptions in primary (AC) power.
