	DESCRIPTION
HOME ABOUT ESD CONTACT ESD ONLINE CATALOG APPLICATION NOTES ORDER QUESTIONS DOWNLOAD LITERATURE LIST PRICE  & SELECTION GUIDE	The PDD-8PCI power distribution control interface converts a main non-power limited DC power source to 8 class II power-limited outputs that can be controlled by a (FACP) Fire Alarm Control Panel.  Each output can be selectively set (J1-J8) to turn ON or to Turn OFF, Trigger disabled always ON when triggered by the panel.  The FACP or other control system can interface to the PDD-8PCI 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 + buss and transfers it to the TRIG + buss.  Jumpers J1-J8 determine which buss 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 PDD-9ST, 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 is ON. Typical applications for a Fire Alarm System would include adding remote Bells and anunciators, closing dampers, turning off HVAC fans, unlocking fail secure and fail safe doors, and / or returning elevators to first floor.  The installation instructions illustrate these applications. The PDD-8PCI is available as a module or mounted in an enclosure with any of our DC Power Supplies.
