MDX-2 1 0.090 0.090
7.
alculate the
Total Alarm Current
in Table 3.
8. Add Steps 2, 4, 5, and 7 together as appropriate.
NOTE: THE MAXIMUM CURRENT OUTPUT IN ALARM CONDITION IS 6 AMPS.
9. Divide Step 8 by the appropriate value for Alarm Time in Amp Hours.
5 minutes of Alarm - divide Step 8 by 12
15 minutes of Alarm - divide Step 8 by 4
