WARNING: DISCONNECT POWER
!
SEVERAL DIFFERENT SOURCES OF POWER CAN BE CONNECTED TO THIS PANEL.
DISCONNECT ALL SOURCES OF POWER BEFORE SERVICING. THE PANEL AND
ASSOCIATED EQUIPMENT MAY BE DAMAGED BY REMOVING AND/OR INSERTING CARDS,
MODULES OR INTERCONNECTING CABLES WHILE THIS UNIT IS ENERGIZED.
Primary Power Source (AC) and Earth Ground Connections
AC power connections are made inside the control panel cabinet. The primary power source for the
panel is 120 VAC, 50/60 Hz, 2.3 amps for the SFP-2402/SFP-2404 or 240 VAC, 50 HZ, 1.15 amps
for the SFP-2402E/SFP-2404E. Run a pair of wires (with ground conductor) from the protected
premises main breaker box to TB8 of the main circuit board. As per the National Electrical Code,
use 14 AWG (2.00 mm
equipment may be connected to this circuit. In addition, this circuit must be provided with
overcurrent protection and may not contain any power disconnect devices. A separate Earth
Ground connection must be made to ensure proper panel operation and lightning and transient
protection. Connect the Earth Ground wire [minimum 14 AWG (2.00 mm
mounting stud. Do not use conduit for the Earth Ground connection since this does not provide
reliable protection.
Secondary Power Source (Batteries)
Observe polarity when connecting the battery. Connect the battery cable to J8 on the main circuit
board using the plug-in connector and cable provided. The battery charger is current-limited and
capable of charging sealed lead acid batteries. The charger shuts off when the system is in alarm.
WARNING: BATTERIES CONTAIN SULFURIC ACID
!
BATTERY CONTAINS SULFURIC ACID WHICH CAN CAUSE SEVERE BURNS TO THE SKIN
AND EYES AND CAN DESTROY FABRICS. IF CONTACT IS MADE WITH SULFURIC ACID,
