 Disabling the key-operation through the Handler interface
If /KEY_LOCK signal of handler interface is set to “1” (low level), the key-operation of panel can be
disabled for that period. The /KEY_LOCK signal is disabling all key-operation. Also in this case, the
KEY LOCK lamp lights up.
Locking by the /KEY_LOCK signal cannot be canceled by the panel operation or remote control
interface. Only when the /KEY_LOCK signal is set to “0” (high level), it can be canceled.
