impedance.
Quick Test
The 13400 provides a “quick test” feature to assist with testing the control unit. A quick
test is performed on a system basis. After placing the system in Quick Test mode, a
zone alarm will cause the system to respond according to normal operation for several
seconds and then automatically perform a system reset. Any notification circuits not
enabled will not sound. Alarm verification is disabled during quick test.
Note: If the control unit is left in quick test over one hour the control unit resets and
disregards the quick test operation.
History Recall
The last zone alarm and last zone trouble or supervisory received can be recalled to the
display by operating a front control unit push-button.
Batteries
The primary stage is responsible for charging and supervising the standby batteries.
The output of the primary stage is at approximately 28V and is designed to charge 24V
lead acid (gel-cell) batteries of up to 17.2 AH capacity. The charger is not designed to
charge nickel cadmium batteries.
The control unit is protected from permanent damage by incorrect (reverse) battery
installation by means of a PCB-mounted fuse. The fuse is not user-replaceable. If a
battery is connected in reverse, the fuse will blow and a trouble will be indicated.
Note: If this occurs, the unit must be returned for repair.
The battery set is supervised for disconnect. The battery is also supervised for low
battery voltage.
