Check for Fire Alarm Verification
You must check the Alarm Verification Box in the lower left corner of the label if you programmed Point 1 for Fire
with Verification. See Point Index in the D6412/D4412 Program Entry Guide (P/N: 45351). See Section 14.0,
Installation Label, for the location of the Alarm Verification Box on each installation label.
3.9
Testing the System
After finishing the installation and programming of the panel, make 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 session.
Walk Test: Use the walk test (Cmd 44) or the point test available in the Installer Mode (see Section 13.0,
Installer's Keypad and Installer Mode) to perform a complete test of the panel.
If you test a device, and the panel does not respond, there may be a problem with the device, the wiring, a
module setting, or the programming for the point.
Clear after test: To clear the event memory and report buffer, momentarily close the Installer Switch. Events
stored in the panel's event log are not cleared.

Power Supply
4.1
Primary Power
4.1.1
Primary (AC) Power Circuit
A 18 VAC, 22 VA internally fused transformer (Radionics model CX4010) is the primary power source. The AC
power circuit provides 700 mA of rectified AC power. The panel reserves 100 mA of this power for internal
operations leaving 600 mA for powered devices.
Transient suppressors and spark gaps protect the circuit from power surges. This protection relies on the
panel's earth ground connection. Make sure you connect the earth ground terminal to a proper ground. See
Section 3.5.1, Connecting Earth Ground.
AC Power Failure
The system indicates an AC power failure when the power at the terminals marked '18 VAC' is interrupted.
Power must be missing for 120 seconds before the panel acknowledges the failure. Power must be maintained
at those terminals for 120 seconds before the panel acknowledges the restoral of power.
4.1.2
Installing the Transformer
Shorting the terminals for prolonged periods of time may cause permanent damage. Connect the
transformer to the panel terminals before plugging it into the power source.
CAUTION
Radionics recommends that you always connect the battery first and then plug in the transformer. See
Section 4.2.2, Installing the Battery, for more information.
IMPORTANT
Use 18 AWG (1.2 mm) (minimum) wire to connect the transformer to the panel. Wire length should be kept as
short as possible. Maximum length is 50 ft. (15.2 m).
AC wiring can induce both noise and low level voltage into adjacent wiring. Route phone and sensor loop wiring
away from any AC conductors, including the transformer wire. Route data wiring away from AC and phone
wiring.
Only plug the transformer into an unswitched, 120 VAC, 60 Hz power outlet. Secure the transformer to the outlet
with the screw provided.
4.2
Secondary Power
4.2.1
Secondary (DC) Power
A 12V, 7 Ah sealed lead-acid rechargeable battery (D126) supplies secondary power for auxiliary and alarm
outputs, and powers the system during interruptions in primary (AC) power.
Lead Acid Batteries ONLY: The charging circuit is calibrated for lead-acid batteries. Do not use gel-cell or
nicad batteries.
Larger Battery Increases Back-up Time: To increase battery back-up time, connect a 12V, 18 Ah battery.
