1.4. Fault contact

Loopdrive provides fault contact output per loudspeaker line for integration with any Voice Alarm System via
programmable control inputs. Every loudspeaker line can have separate contact closure, or – depending on the
system design – multiple loudspeaker lines can share common fault contact.
The contact is normally open during quiescent mode of the system. During quiescent mode:
a. Loopdrive system is powered and running, monitoring entire loudspeaker line,
b. Power amplifier is connected,
c. Loop is closed and fully working, every T-Branch is fully operational,
d. No faults detected.
Any other state, including service mode, amplifier disconnection or even power failure of Loopdrive, will immediately
close the contact, reporting failure to the main system.
