18.3 AC Line Fuse Replacement

The AC line fuse on Allegiant power supply models is found on the rear of the equipment bay near the line cord connector. Power supply models for 220-240 VAC input version may contain a circuit breaker equipped power switch which can be reset directly from the front. If the line fuse needs to be replaced in a 120 VAC model power supply, remove the line cord from the system. Insert a flat blade screwdriver into the slot located at one end of the connector housing and rotate the screwdriver until the door to the housing opens. Remove fuse holder from housing as shown in drawing.

18.4 Power Supply Fuse Replacement

The main power supply is located in the far right side of the equipment bay. Remove the front panel of the bay by loosening the four fasteners. Locate the fuse to be replaced by observing the green LED indicators. Note which LED indicators are not lit, then turn OFF the main power switch located on the power supply. Replace fuses associated with LEDs which were not lit. Switch on the main power switch and verify that all LEDs are now lit. Replace front panel.

18.5 Replacement of Memory Backup Batteries

CAUTION

Lithium batteries should be replaced by qualified service personnel only.

 

The memory backup batteries are located on the main CPU card located next to the

 

power supply module in the main CPU bay. The batteries provide RAM memory

 

backup for a period of at least one year. They are only active when main AC power

 

to the system has been lost. The RAM memory is used to store system operational

 

data which is frequently changing, including time/date and system crosspoint data

 

(i.e., which camera is currently being displayed on which monitor). More vital sys-

 

tem data such as camera titles, alarm settings, user information and passwords, etc. is

 

stored in non-volatile memory that is not affected by the condition of the batteries or

 

the main AC power.

 

Remove the front panel of the main CPU bay by loosening the four fasteners. The

 

two batteries are mounted on the front edge of the CPU card and are about 25 mm

 

(1 in.) in diameter. Insert a small flat blade screwdriver into the slot on one of the
