Rev. C April 1999
Note 4:
If no amplifier is installed in the slot then the current for that amplifier is zero. If there is an amplifier the alarm current
depends on the model of the amplifier installed in the slot and the signal used for evacuation.
Model Alarm Current full power SIN wave as per UL testing
SALL-15S Series The sum of the currents of the self amplified speakers.
SAA-10S/SE Series (total wattage of connected speakers) x 69 + 240mA
SAA-40S/SE Series (total wattage of connected speakers) x 55 + 400mA
SAA-80S/SE Series (total wattage of connected speakers) x 56 + 600mA
Alarm Current for: Temporal Worst case
CODE-3 tone
Typical Voice TONE HI/LO
SAA10S/SE Series 250mA 350mA 750mA
SAA40S/SE Series 600mA 750mA 1600mA
SAA80S/SE Series 1000mA 1050mA 2500mA
Note 5:
The alarm current of the DV depends on the model DV installed.
Model Alarm Current
DV-100 250mA
DV-200 300mA
Note 6:
Use the rated current for the optional trouble audible attached to the system.
Note 7:
If no strobes are installed in the zone the current is zero. If strobes are installed, the current is the sum of the current ratings
of all the strobes attached to the zone.
Battery Capacity Calculations:
The battery capacity depends on two factors; the current being drawn from the battery and the amount of time that the current is
being drawn. The battery capacity is measured in amp hours. The total amp hours of batteries needed is (the standby current) x
(time in standby) + (the alarm current) x (time in alarm).
Sample Calculation:
The system is equipped with a DV-100, an RMS-1, a remote trouble audible that is rated for 100mA, and three amplifiers. The first
amplifier is an SAA-10S Series with 10 watts of speakers attached and 1 amp of strobes attached. The second amplifier is an SAA-
80S Series with 60 watts of speakers attached and 2 amps of strobes attached. The third amplifier is an SALL-15S Series with 10,
100mA self amplified speakers attached and no strobes attached. The system is designed for 24 hours of standby and 15 minutes
of alarm.
Standby Calculations:
System Controller Board 150mA
Amplifier 1 125mA
Amplifier 2 300mA
Amplifier 3 100mA
Amplifier 4 0mA
Digital Voice 200mA
Optional RMS-1 40mA
Optional Trouble Audible 100mA
_______
Total: 1015mA = 1.015 amps
Alarm Current Calculations:
System Controller Board 150mA
Amplifier 1 350mA
Amplifier 2 1050mA
Amplifier 3 1000mA
Amplifier 4 None 0mA
Digital Voice DV-100 250mA
Optional RMS-1 750mA
Optional Trouble Audible 100mA
Zone 1 Strobes 1000mA
Zone 2 Strobes 2000mA
Zone 3 Strobes 0mA
Zone 4 Strobes 0mA
________
Total: 5975mA = 5.975 amps
Battery Capacity Calculations:
24 hours x 1.015 amps + 1/12 hour (5 minutes) x5.975 amps = 24.86 amp hours minimum capacity. Any de-rating factor must also
be included.
