Detector reset (L+ when programmed for ID)
Some detectors require the removal of power to reset (such as Viper Plus®
or Smoke detectors). You can program the L+ terminal to be used as an ID
output using option 7-4. The L+ terminal should then be used as the
negative supply for these devices. The positive supply should be taken from
the AUX +.
