Section 8: Operation

8.7 OPERATION COMMANDS
Eight commands, called direct, are used to override but not reconfigure the system. These
commands are CLOSE, LIMIT, OPEN, RELOCK, SHUNT, SILENCE, UNLOCK, and UNSHUNT.
When these commands are invoked, an OPERATOR OVERRIDE log message is generated.
If power to the Alto 818 is disrupted, or if the system is reset, the ACU will cancel these direct
commands. Only program command data (i.e., the database) is retained in memory when power
is restored.
8.7.1 CLOSE
This is an operator override command which manually changes the building mode to closed.
When this command is entered, the system first enters the limited mode for one minute before
going to closed mode. The mode can be changed again with another operator command.
8.7.2 FORGIVE
Use the FORGIVE command to manually reset all key holder locations to unknown. The location
will change when the key holders next access an exit or entrance. The command is required only
if anti-passback has been enabled.
8.7.3 LIMIT
This operator override command is used to manually change the building mode to limited. Using
this command, the building will remain in limited mode until another operator override command
is entered.
