DF6000 - USER MANUAL

German Interface Electrical Characteristics

Inputs

The inputs are designed to be actioned in one of two ways, see list below:

First: A change in logic state ie. switch toggled on / of

Second: Logic pulse ie. nominal state logic high, then logic low > 200mS then return to logic high.

all inputs are held high via a weak pull up (logic high), the action of short circuiting any of the ﬁve inputs to

there respective 0v will result in a logic low.

1: reset -> logic pulse

2: FRE relay test -> logic pulse

3: FPE disable -> logic state change

4: FRE disable -> logic state change

5: Acoustic disable -> pulse logic

Monitored Inputs

In Fault / Extinguisher Active

-> End Of Line resistor 3K3.

-> 680 Ohm across input to actiavte input

Relay Outputs

Normal status -> Input sees a 3K3 resistor.

Active status -> Input sees a 680 ohm resistor.

Outputs

1: Extinguisher released -> output high 26 V

2: FRE operated

3: FPE disabled

4: FRE disabled

5: Panel in ﬁre, will remain on after panel soft reset for > 15 minutes, or extinguish immediately with

interface reset

6: Disable all sounders.
