Description
The PDB-8C1R power distribution control interface converts a main non-power limited DC power source to 8 power-limited
outputs that can be controlled by a (FACP) Fire Alarm Control Panel. For the model PDB-8C1R /8F1R each output can be
selectively set (J1-J8) to turn ON or to Turn OFF when triggered by the panel. The FACP or other control system can interface to
the PDB-8C1R /8F1R with either of two or both supervised trigger inputs. One trigger is activated with a reverse polarity voltage
from a FACP. This trigger is fully isolated with an optical isolator. The other trigger is an (EOL) 2.2K End Line Resister input which
will accept a (N/O) Normally Open switch or a (N/C) Normally Closed switch.
When triggered, the Trigger Transfer Relay removes power from the NORM + bus and transfers it to the TRIG + bus. Jumpers J1-
J8 determines which bus each output is connected to. The triggered form C contacts also drop off normal when triggered and
the Red (TRG) LED turns on. These contacts can be used to daisy chain other PDB-8C1R, latch, or provide feedback to a system.
The Trouble Form C Relay drops off Normal if any one of the PTC circuit breakers is tripped, or main power/fuse is lost. The Green
(TRB) LED is ON during normal operation, it goes off with trouble. All three relays are Fail-Safe, energized in the normal
condition.
Each output has a Green LED that is on when the associated output (-1+ through -8+) is ON.
Typical applications for a Fire Alarm System would include adding remote Bells and enunciators, closing dampers, turning off
HVAC fans, unlocking fail secure and fail safe doors, and or returning elevators to first floor.
