1.3 Architecture
To meet the National Fire Protection Association (NFPA) requirements, power to the Signal booster is
provided via an uninterrupted power source. This can either be a UPS or (if a UPS is not available),
an AC Feeder and Battery Charger (purchased separately).
NOTE: The Power Feeder Battery Charger is described in Chapter - 4).
Alarm connections to the Fire Department Control Box are used to monitor the status of the
uninterrupted power source, Signal Booster and DAS system (antennas).
NOTE: As an alternative to the Fire Department Control Box connections, the D-MBR PS NFPA and
UPS or Charger dry contact alarms can be connected to an Automatic Dialer. The AD-2000
Automatic Voice/Pager Dialer System is recommended.
If the AC power to the UPS fails, the required power is provided by the battery and the AC Power Fail
alarm is activated.
