Description of PDD-FT-1.5 Connections
See Fig. 1
Input Power
“-INPUT+”: 2 Pos. Terminal block with self clamping screws will accept multiple 12AWG
wires Universal input.
Output Power
Two 2 Pos. Terminal blocks. Self clamping screws will accept multiple 12AWG wires.
“-N/ON+” are normally ON output power. This output is ON when the PDD-FT is not trig-
gered. “-N/OFF+” is normally OFF. This output is ON when this unit is triggered. The trans-
fer relay is rated at 1.5Amps.
Power LED’s
A red led above each output indicates which output is active.
Input Trigger EOL*
2 Pos. Terminal block – Will accept 12AWG wire. This input must see the 2.2K ohm end of
line resistor to be in the normal set condition. A change in resistance of ± 50% will cause
the trigger relays to drop out in the Triggered mode. This change in resistance is caused
by the supervised wire between the EOL at the fire panel and the PDD-FT being shorted or
opened. The EOL supervises the pair of wires.
Input Trigger OVR*
2 Pos. Terminal block - Will accept 12AWG wire. This pair is normally closed and can be
connected to an override switch. When OVR is open, unit will trigger.
Input Trigger AUX-IN*
2 Pos. Terminal block - Will accept 12AWG wire. This pair is normally closed and can be
connected to an auxiliary device. When AUX-IN is open, unit will trigger.
Reset 2 Pos. Terminal Block*
2 Pos. Terminal block - Will accept 12AWG wire. When this pair is shorted, input triggers
do not latch. If pair is open, the input triggers will latch until alarm is corrected and RESET
is momentary closed to reset trigger.
*Minimum 22AWG and maximum distance of 6170ft for field wiring.
Jumpers RST - OVR - AUX
Jumpers are used to activate (remote) features as required.
Jumpers GRN
This jumper is used to enable ground supervision or the inputs. If the jumper is connected
to both headers, and the mounting hole adjacent to jumper is connected to earth ground, a
ground on any of the input triggers will cause a trigger.
Trigger Status Terminal block
Two 3 Pos. Terminal blocks - Will accept 12AWG wire. Form C DPDT Contact with a 1
Amp rating will indicate the condition of trigger. C and NO are normally open in the normal
energize not triggered state. C and NC are normally closed in the normal energized not trig-
gered state. These contacts may be used to provide feedback to the FACP or other auxilary
devices.
