Table 2-4 Testing Circuit Supervision
Condition
To create an open:
• Class B Circuit. Remove the
end-of-line resistor from
either the IDC or NAC.
• Class A Circuit. Disconnect
the return wiring from the
main system board (NAC
only), or from the IDC Class A
module.
To create a short:
Apply a zero ohm jumper across
the IDC or NAC circuit.
To create an Earth ground:
Place a 10K or smaller value resis-
tor from supervised wiring to Earth
ground.

Replacing Lithium Battery

The panel uses a lithium battery to maintain non-volatile
memory on the panel. In the event of a total power-down
(AC power and lead-acid battery), the lithium battery allows
the panel to maintain all historical logs, time/date informa-
tion, list of disabled points, and the alarm verification tallies.
Important Note: The lithium battery must be replaced only
by a qualified service technician.

Periodic Testing and Maintenance

The minimum requirements for periodic testing of the fire
alarm system are outlined in chapter 10 of NFPA-72, 2002
edition. Local codes may require additional testing and
maintenance. All system components must be tested in
accordance with governing codes. Specific details on select
system components are provided below.

Smoke Detector Tests

The detectors include magnetically operated functional tests.
The magnet tests indicate if the detector is within sensitivity
settings. The detector will also indicate whether or not it
needs cleaning due to buildup of dirt or dust. This indication
is via LED blink codes. The table shown below shows the
blink codes associated with the detectors during magnetic
test. Refer to the detector installation documents for addi-
tional details.

If you have programmed a front
panel or annunciator LED to detect
Earth ground conditions, the pro-
grammed LED also illuminates.

manual for information on program-
ming an Earth Fault LED.
Chapter 2. Installation and System Checkout
Test mode is activated by placing the magnet at the location
indicated by the "I" mark, which is embossed on the detector
housing. The visible LED flashes to indicate the detector's
condition.
• NORMAL - When in test mode, the detector latches
into alarm if the unit is within calibration range. The
visible LED stays on, with no blink codes transmitted.
• MORE SENSITIVE - When in test mode, if the detector
is too sensitive, (more sensitive than the maximum cali-
bration), the visible LED quickly flashes, at a twice per
second rate. Following the sixth flash, the detector
latches into alarm and the visible LED stays ON.
• LESS SENSITIVE - When in test mode, if the detector
is less sensitive than the minimum calibration, the visi-
ble LED slowly flashes, at a rate of one flash every two
seconds. Following the fourth flash, the detector latches
into alarm and the visible LED stays ON.

Battery Tests

The batteries used with the 4006 FACP are sealed lead-acid
type. The battery charger is temperature compensated per
battery manufacturer recommendations. There is no charger
voltage adjustment. Batteries should be tested by discharg-
ing them with a suitable tester and verifying that battery
voltage is at least 21V when fully discharged. Battery dis-
charge tests should be performed annually, and batteries
should be replaced no longer than 4 years from date of
installation. Batteries should be installed within six months
of the date of manufacture. At normal room temperature,
battery voltage should be 27-27.6V when the battery set is
fully charged. At higher temperatures, the voltage will be
lower. At lower temperatures, the voltage will be higher. The
battery charger has a negative temperature coefficient. At
higher temperatures, the chemical process in the battery is
accelerated. This means that the ideal charger voltage is
lower. Likewise, at lower temperatures, a higher output volt-
