Battery Maintenance and Check
4-3.2.1
BATTERY STATUS CHECK
The battery backup used inside the power supply to power
the detector must be tested every six months.
A battery-status check is best accomplished by running the
load with the batteries for about one hour and, while the
load is still on, measuring the individual battery voltages. If
any battery reads 1.5 V or more below its rated voltage,
that battery should be replaced.
Generally, if one of a series set of batteries is low, the oth-
ers will soon fail. Therefore, it is advisable to replace all the
batteries of a series set when one requires replacement.
Any battery that has been in service for 36 months or more
must be replaced.

BATTERY TEST
Procedure:
1. Press the down arrow to display the Main Menu.
2. Select Test.
3. Select Battery Test.
4. Select the unit you want to test. Use the up and down
arrows to scroll through the units. Then press ACCEPT.
The display then shows the battery open circuit volt-
age and the charging current which will be displayed
until the operator presses the ACCEPT button.
This test is not available when the unit is running off the
battery or when there is any alarm condition on the unit.

REPLACING THE BATTERY
Space is provided in the Main Control Panel and Remote
Hazard Unit enclosures for two 12 AH 12 Vdc batteries for
24-hour standby operation.
!
CAUTION
Before servicing batteries, disconnect AC
power. Batteries should be replaced at least
once every 36 months, or as directed by the
local Authority Having Jurisdiction. Do not
install a battery set whose open circuit voltage
is less than 22 volts.

The LCD/LED test can only be performed when there are
no current alarms (when there are no alarms the ALARM,
SUPERVISORY, TROUBLE, and SIGNAL SILENCED in-
dicators are not lit and the display shows the status mes-
sage).
To test the LCD/LEDs, hold down both of the scroll keys
simultaneously for at least 1 second. If status is normal,
the following occurs:
•
Every indicator lights in a special pulsed mode (one
second on, then two seconds off). This pattern contin-
ues as long as the scroll buttons are pressed. The LCD
also lights every character box, then displays "LCD/
LED TEST."
•
The buzzer sounds in the same pulsed manner (one
second on, then two seconds off). It continues to sound
as long as the scroll buttons are pressed.
•
An LCD/LED test message displays.
Release the scroll keys to end the LCD/LED test.
4-3.3.1
Turn VR1 on the printed circuit board clockwise to increase
contrast on the LCD display (see Figures 7-2, 7-3 and 7-4).

Short circuiting, mutilation or incineration of the battery must
be avoided to prevent one or more of the following occur-
rences:
•
•
•
If a battery has leaked or vented, use protective
gloves to handle the printed circuit board
assembly. If the printed circuit board is being
returned to the factory, follow proper
procedures for returning.
