2. Calculate speaker output current by totaling all the speaker wattage settings.
Multiply the sum by 0.040. The result is the current draw in Amps.
3. Add the strobe current, the speaker current, and auxiliary current together. The result
is the total Alarm Current in Amps.
4. Alarm circuits are required to operate for 15 minutes on battery power. Multiply Step
3 by 0.25 hrs. The result is the total Alarm Capacity Required in Amp-Hours.
4.8.3.3 Battery Calculations
Good engineering practices recommend the total Amp-hours required for backup should not
exceed 90% of the Backup Battery capacity. The SP40S Multi-Function Facility
Communication System has been UL approved for a maximum of 33 Ah batteries. The
enclosure can accommodate up to 12 Ah. Batteries greater than 12 Amp-Hours (Ah) are
required to be installed in a UL listed battery box.
1. Add the total Standby Capacity Required to the total Alarm Capacity Required.
2. Multiply Step 1 by 1.25. This is the minimum Backup Battery requirement for this
panel.
3. Record results on worksheet.
4.9 Installing AC Power and Batteries
NOTE: Power-limited and non-power limited wiring must be separated. Wire non-power
limited wiring (AC power and battery) to the left of the motherboard. Wire power limited
wiring to the right and top of the motherboard.
WARNING: TWO DIFFERENT SOURCES OF POWER SHOULD BE CONNECTED
TO THIS UNIT. DISCONNECT BOTH SOURCES OF POWER BEFORE
SERVICING. FAILURE TO DISCONNECT BOTH POWER SOURCES BEFORE
SERVICING COULD RESULT IN SERIOUS INJURY OR DEATH TO YOU AND/OR
OTHERS.
4.9.1 Installing AC Power
1. Refer to
Figure 22
and connect the line and neutral input wiring to the L (Line) and
N (Neutral) terminals on the terminal block TB9 (see
Figure 4
for location) in the
lower left corner of the chassis.
2. Ensure that the ground input wiring is connected to the ground terminal (TB9) on the
left side of the chassis.
3. Secure the wire with the caps nut located in the hardware package.
CAUTION: Observe correct polarity requirements on all connections. Failure to do so
may damage the equipment.
CAUTION: Always apply AC voltage before applying battery backup voltage. Failure
to do so may cause damage to the SP40S Multi-Function Facility Communication
System.
