"Check" and "Battery" Displays
Not all systems use wireless sensors.
TROUBLE CONDITIONS
The word CHECK on the keypad's display, accompanied by a "beeping" at the keypad, indicates a trouble condition in the system.
To silence the beeping for these conditions, press any key.
1.A display of "CHECK" and one or more zone numbers indicates that a problem exists with the displayed zone(s) and requires your attention. If the CHECK display relates to a fire zone, CALL FOR SERVICE IMMEDIATELY.
Determine if the zone(s) displayed are intact and make them so if they are not. If the problem has been corrected, the display can be cleared if you enter the OFF sequence (user code plus OFF key) twice. If the display persists, CALL FOR SERVICE IMMEDIATELY.
2.If there are wireless sensors in your system, the CHECK condition may also be caused by some change in the environment that prevents the receiver from hearing a particular sensor. CALL FOR SERVICE IMMEDIATELY if this occurs.
