Switches 0V with intrusion alarm from all
areas for the set alarm time
Switches 0V with personal attack from all
areas for the set alarm time
Switches 0V at external unset system, high
impedance if externally set.
Switches 0V, if no malfunction from power
supply, common fail or processor present
Switches 0V for approx. 3 seconds if system
has been externally set (armed)
Switches 0V if system ready to set externally
Switches 0V on internal alarm
Switches 0V if system unset.
