Special Wireless Displays
Your system may use wireless transmitters to send alarm and 
trouble information from the protection devices to the panel.  
Wireless systems operate the same as hard-wired and also have a 
few unique keypad displays.
BACK DOOR - LOBAT - (Low Battery) The battery in a radio 
transmitter is low. (BACK DOOR is used as an example only.)
BACK DOOR - MISNG - (Missing) The panel is not receiving the radio 
transmitter periodic test report.
WIRELESS - TRBL - (Trouble) Some part of your wireless system is 
operating improperly. Test the system to locate the trouble.
 Understanding Security System Terms
Throughout this guide, and in some displays on your keypad, you 
will see certain words or phrases that might be unfamiliar. Below 
are some terms you will see here and on your keypad display:
Access (Door Access)
Entry/Exit doors that are used to restrict access to the building  
or provide door access to authorized users. When a user code is 
entered at the keypad by entering a code or presenting a card to 
a reader, the system veriÞ es authority and unlocks the door for a 
short period of time. See Easy Entry User’s Guide in Appendix C.
Areas
An area is made up of burglary zones that can be armed or disarmed 
together. One area might consist of the ofÞ ce doors and windows.  
When you arm the ofÞ ce, these zones arm together and sound an 
alarm if opened.
Arming
Turning on the burglary protection in one or more areas of the 
system. When armed, the system is able to sound alarm bells or 
sirens and, if monitored, send alarm reports to a central station 
when a burglary zone is tripped.
Fire, panic, and other 24-hour devices are always turned on and do 
not need to be armed.
Fault
You may see the keypad display FRONT DOOR —FAULT. This means 
that there is a problem with the front door, such as the door being 
open when you are arming the system. If you see a —FAULT display, 
attempt to correct the problem (in this case shut the door). After 
the zone is in a normal state, you may arm the system. You may 
also bypass the zone and then arm the system. 
Central Station Monitoring
Your system can also be programmed to automatically send 
alarm, trouble, and arming and disarming reports to a central 
station. Operators at the central station dispatch the appropriate 
authorities or contact you with the speciÞ c event information.
Disarming
Turning off one or more areas of the system. When disarmed, the 
system does NOT sound alarms or send alarm reports to a central 
station when a burglary zone faults.
