Battery Calculation Worksheet; Testing And Maintenance - Altronix FireSwitch108 Installation Manual

FireSwitch User Interface and Programming via Ethernet Port (cont'd):
Step 2. Connect a laptop or PC to the Ethernet port of your FireSwitch unit. FireSwitch unit should be powered up
at this moment.
Step 3. Open a browser window (it is necessary to update your browser software to the latest version so that the pages
display and function correctly).
Step 4. Enter the IP address (the default IP address is 192.168.168.168) into the address bar.
Status page will be displayed.
Step 5. Click Setup link. You will be prompted for an administrative password, type and submit the password
(the default password is "11111111"). Setup page will be displayed. You may now program your FireSwitch.
Device
For each device use this formula:
FireSwitch
(Current draw from battery)
A
Auxiliary Devices
Auxiliary Devices Current (must not exceed 1 amp - 0.45 amp for
B
Canadian applications)
C Notification Appliances Current must not exceed 10 amp (10,000mA)
D Total alarm current (A + B +C)
E Total current ratings converted to amperes (line D x .001)
F Number of standby hours (24 for NFPA 72, Chapter 1, 1-5.2.5).
G Multiply lines E and F.
Alarm sounding period in hours.
H
(For example, 5 minutes = .0833 hours.)
I Multiply lines E and H.
J Add lines G and I.
Multiply line J by 1.30.
K
(30% extra insurance to meet desired performance)
Total ampere - hours required
If total ampere - hour required exceeds 40AH, decrease AUX current to provide enough stand-by time for the application.
Select a battery with AH rating equal to or greater than the value calculated.
Unit should be tested at least once a year for the proper operation as follows:
Output Voltage Test: Under normal load conditions, the DC output voltage should be checked for proper voltage level.
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage both at
battery terminal and at the board terminals marked [+ BAT -] to insure there is no break in the battery connection wires.
Note: Expected battery life is 5 years, however it is recommended changing batteries in 4 years or less if needed.
