  connected  to  the  fire  alarm  system  at  all  times. The primary and
  secondary power sources shall be arranged and  controlled  by  automatic
  transfer  switches  dedicated  to  the  fire  alarm system such that the
  secondary source will be  automatically  connected  to  the  fire  alarm
  system  should  the  primary power source fail. The following conditions
  shall be observed:
    (1) Intermediary devices between the fire alarm  system  power  supply
  and the power source, other than fused disconnect switches, transformers
