Ground Connection

The Firecom 4100 Portable Intercom System is powered by a sealed lead-acid rechargeable battery housed in the
base unit. Before you can put the 4100 Portable Intercom System to work, you must charge the battery with a full
charge.
Connect the battery charger to the back of the main unit and plug the battery charger into an indoor 120-volt AC
outlet as shown in figure 3. Initial battery charge time is 24 hours. After the initial battery charge, charge time will
decrease according to usage. The battery charger unit comes with an indicator light. The light will illuminate red if a
fault condition exists, yellow when the unit is charging, and green when the charger is in float (slow charge) mode.
The 4100 Portable Intercom System will operate up to 80 hours on a full charge. Do not drain the battery completely.
