Using the PU2 to PU6 jumpers, you can set each contact as a normally open (NO)
contact or a normally closed (NC) contact (see chapter 5.3.2).
In programming step 3, you can change the function of potential-free contacts 1 to
3 depending on the application:
Contact 1: Option 1 = Active on state "Released" until "Reset"
Option 2 = Active on state "Activated"/"Released" until "Reset"
Option 3 = Active on state "Fire alarm"
Option 4 = Active on state "Fire alarm"/"Activated"/"Released"
Contact 2: Option 8 = Active on state "Fault" until "Silence buzzer"
Option 9 = Active on state "Fault" until cause is removed and
Option 10 = Immediate activation
Option 11 = 3min delay in state "Buzzer non silenced"
Contact 3: Option 5 = Active on state "Fire alarm" to "Reset"
Option 6 = Active on state "Fire alarm"/"Activated" to "Reset"
Option 7 = Active on state "Emergency Hold/Abort" until the cause is
In the basic configuration, potential-free contacts 1-3 are set in programming step 3
as follow:
Contact 1 is set to be active on state "Released" to "Reset" (= option 1)
–
Contact 2 is set to be active on state "Fault" until "Silence buzzer" and
–
immediate activation (= option 8 + 10)
Contact 3 is set to be active on state "Fire alarm" to "Reset" (= option 5)
