  • When the volt-free contacts connected to the Switched Input Module are closed, all interconnected smoke, heat and CO alarms will sound.
  • When the device triggering the Switched Input Module resets (i.e. when the contacts switch back) it will automatically reset and all interconnected alarms will cease sounding.
