WARNINGS
• Electrocution hazard. To avoid personal injury or death from electrocution,
make sure the distribution circuit providing mains AC is rendered inoperative
prior to connecting mains input wiring to the PS10-4B Power Supply.
• Electrocution hazard. To avoid personal injury or death from electrocution,
remove all sources of power and wait 11 minutes to allow stored energy to
discharge before installing or removing equipment.
Caution: Circuit boards are sensitive to electrostatic discharge (ESD). To avoid
damage, follow ESD handling procedures.
One PS10-4B Power Supply Board is required for each control panel. The power
supply provides the required power and related supervisory functions for the
control panel as well as filtered, regulated power, and 24 VDC output for
operating notification appliances and ancillary equipment.
