Figure number 8 – Setttings of alarm extinguishing function
●
Door sensor switch
Prevents extinguishing to discharge when the door is open. Opening the door turns on the
door switch and this deactivates the extinguishing. The reason is that with the door open, the
extinguishing agent would not reach the required concentration inside the cabinet. The
integrity of the contact circuit is constantly monitored.
The wiring diagram for the door contact is shown in Figure no. 10.
When the extinguishing is blocked, the „EXTINGUISHING” indicator on the front panel
lights up yellow
The door sensor switch must be first set, after connecting to the web interface in the menu
Alarms
-> Select alarm 2 Door, by selecting the Blocking function and activating the
functionality of the door switch sensor. Several door sensors can be connected in parallel. The
circuit must always be terminated with a terminating resistor, see Figure no. 10.
