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
f.
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.
