Comnet PDD-FT DC Fire Transfer Relay Module

The PDD-FT transfers the input power from the normally ON output pair “-N/ON+” too the normally OFF output pair “-N/OFF+” when triggered. The unit is triggered when the supervised (EOL), end of line resistor is opened or shorted. The triggered form C user contacts indicate the state of the trigger. A typical application of the PDD-FT is to place a distribution board on one or both of the outputs, one of our power supplies on the Input, then connecting the EOL at a fire alarm panel to transfer the power from one distribution board to another when the Fire alarm panel is in the alarm condition. The transferred power would be used to unlock doors, shut down air systems, or return elevators to an exit floor.
