When installing the battery charger as a replacement part, it is necessary to verify the proper charger
settings and adjust as necessary.
1. Incoming AC voltage 115 or 230 volts.
2. Battery voltage – 12 or 24 volts DC.
3. Battery type – Lead Acid / Ni-Cad 9 or 18 Cell / Ni-Cad 10 or 20 Cell.
If battery charger is powered with the incorrect settings, damage to the charger and/or batteries may occur.
The Firetrol® battery charger features a fully automatic 4 step charging cycle. The charging cycles are as
indicated:
Step 1: Qualification Stage (Flashing yellow and green LEDs)
During this stage, the battery charger checks the batteries to insure they can accept a fast charge.
It also checks for missing or defective batteries. If the charger detects missing or defective batteries
a fault will be given (solid red LED).
Step 2: Fast Charge (Solid yellow LED)
Charges the batteries until they reach peak voltage.
Step 3: Bulk Charge (Solid yellow LED and slow blinking green LED)
Charges the batteries at a constant potential of peak voltage until current reaches 500mA.
Step 4: Float Charge (Solid green LED)
Trickle charges the batteries to maintain peak potential.
• Charger reset push-button (resets charging cycle to beginning)
