6. Input signal
The Density fog generator has 4 +1 inputs to control the fog operation.
4 inputs are galvanically isolated optocoupler inputs. They are normally triggered by 12VDC applied.
You can choose if the inputs shall be activated by NO or NC logic (Normal Open or Normal Closed),
meaning that you can choose to activate the inputs, by 12VDC Removal or by 12VDC Applied.
1 input is dedicated to the use of a verifying PIR sensor. This input is not galvanically isolated. This special
input has a separate 12VDC power supply to power the PIR sensor.
The 4 inputs:
Input 1: ARM - ARM input for ARM or DISARM the machine.
Input 2: SHOOT - Will make the machine SHOOT when ARM is activated.
Input 3: IN- 0 - Verication input. Logical function is «AND» with input 2 «SHOOT».
Input 4: IN-1 - PANIC alarm input. Will make the machine SHOOT, regardless of the status of ARM input.
PIR sensor input:
Contact signal - Closes to negative (PIR C to PIR -)
To activate this input, the jumpers W1 is used.
W1 closed activates this PIR input as an “AND” input, meaning that the fog generator is triggered when
both “SHOOT” AND “IN 0” AND “PIR” is activated. (ARM must be activated)
Changing logic (NO or NC):
By turning DIPSWITCH 6 = ON, you select the 3 inputs, ARM, SHOOT and IN 0, to be NC activated.
NC means Normal Closed, and that means that you activate the inputs by 12V Removal. In rest, you will
have 12V applied on the inputs. To activate the inputs, you break the circuit, and thereby you have 12V
removed from the inputs.
