“Loop” Trigger - E.T. Systems Drive 500 User Instructions

Basic operating
features
The Loop trigger mode is exactly the same as Condominium auto-close mode.
The only way to trigger loop detector mode is via the hardwired LPT input.
In Loop detector mode, a LPT trigger is treated as open, and any BT or LPT trigger is treated as a keep opening, keep open triggers or re-open trigger
while the gates are running. The gates will only close once the auto-close timer has timed out. The loop mode transaction will only clear once the
gates reach the closed position again.
NB! For any auto-close feature to work, a pair of safety infra-red beams must be installed and functioning correctly. If no safety infra-red beams are
installed then the gates will open but not close again.
