Fig. 3 - Fire Panel Connections for Latching Release with N/O Manual
Reset
This application illustrates how to connect the PDD-FT to a power supply for main input as
well as a fire alarm control panel. If wired in this manner, outputs will change state when-
ever the fire alarm relay activates and remain latched in the triggered state until reset by
activating the N/O switch.
Note: Remove RST jumper for manual reset operation.
Remarque:
Retirez la bretelle RST pour effectuer une ré
initialisation manuelle.
Fig. 4 - Connections for Non-Latching release reset using multiple
PDD-FT boards
This application illustrates how to connect the PDD-FT to a power supply for main input
as well as a fire alarm control panel. If wired in this manner, outputs will change state only
as long as the fire alarm relay is active. When the fire alarm resets the PDD-FT outputs will
also reset. Connecting the EOL input of one board to the trigger relay of the next board as
shown will allow for override and reset of multiple boards.
Note: The RST jumper must be left in place on all boards for automatic reset operation.
Remarque:
La bretelle RST doit être laissée en place sur tous les panneaux pour effectuer
une réinitialisation automatique.
