The BN power supply is configured to provide either 12 or 24 VDC to one PD8(F) power
distribution module.
The PD8(F) will split the 12 or 24VDC into eight individually protected outputs for use in
powering locks, doorstrikes, or auxiliary equipment such as REX PIRs, keypads, egress
timers, or readers.
The diagram illustrates a common eight door system with two maglocks used for the
egress doors, six doorstrikes used for internal access control and a mix of auxiliary
power needs such as cameras, keypads, and REX PIRs. Emergency access buttons
should be used on the maglocks due to FAI not being used.
The PD8 should be used for Class 2 power limited service.
The PD8F should be used if fuse protection is desired.
A single battery set is used to provide standby power to both the locks and the control
equipment.
All components as shown will fit within a B02 (12"H X 12"W X 4"D) enclosure , while
allowing space for a 12V - 14 Ah or 24V - 7Ah standby battery set.
