Security Key-Switch Configuration - ASL INTERCOM VAR4 Operation Manual

Security Key-switch Configuration

Security key-switches can be configured to protect the operation of any microphone button.
When a button is protected, then the security key must be turned on for the button function to be allowed.
This security function is intended to safeguard emergency DVA triggers from inadvertent operation, but it
may also be used to protect buttons programmed for other purposes.
