Remote Station or Auxiliary Systems
Remote Station or Auxiliary Systems require 60 hours of standby plus 5 minutes of alarm operation at the end of the 60 hour period. A D8132 Battery Charger Module with additional batteries installed in a separate D8109 or D8108A enclosure may be required in the D9112 system to meet the basic standby requirements for a Remote Station or Auxiliary System installation. You must use battery ampere hour (Ah) calculations to verify compliance. The following formula includes the calculation for 5 minutes of alarm operation at the end of the 60 hour period, as well as a 10% contingency factor which allows for depletion of battery capacity with age.
Remote Station or Auxiliary Systems
Total B | Hours | Total C | Hours | Contingency | Total Ah |
( ________ | x 60 ) | + ( _______ x | .083 ) + | 10% | = __________ |
Total Ah requirements must not exceed Ah capacity of batteries:
Two D126 Batteries = 14 Ah
Household Fire Warning Equipment
The Household Fire Warning Equipment Standard requires 24 hours of standby plus 4 minutes of alarm operation at the end of the 24 hour period. You must use battery ampere hour (Ah) calculations to verify compliance. The following formula includes the calculation for 4 minutes of alarm operation at the end of the 24 hour period, as well as a 10% contingency factor which allows for depletion of battery capacity with age.
