Commands
Commands allow you to carry out various tasks such as add or delete passcodes,
set the date and time, or test the system. Each command is detailed throughout this
user guide.
Commands are written as: [CMD] [6] [3]. To enter this command, first press the
[CMD] key, followed by the [6] key, and then the [3] key.
System Events
Your system responds to four types of alarm events. If more than one event occurs,
your system sorts them into one of four groups:
• Fire Alarms (highest priority)
• Burglary Alarms
• Fire Troubles
• Non-Fire Troubles (lowest priority)
Events grouped as highest priority are always sent to the central station first.
