-The KAL740 is an addressable supervised relay output unit for addressable fire system running Kilsen protocol. It allows for the control and supervision of a single, 24 VDC output directly on the fire system loop. The KAL740 may be used to control for e.g. sounders in case of fire conditions, but may also be used to switch any output considered crucial enough to have the cable integrity between the unit and the switch point monitored.
