TROUBLE CONDITIONS
"Check" and
"Battery" Displays
* Not all systems use
wireless sensors.
T he 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 se-
quence (user code plus OFF key) twice. If the display persists, CALL FOR
SERVICE IMMEDIATELY
.
2. If there are wireless sensors* in your system, the C H E C K 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.
IF YOU CANNOT CORRECT A "CHECK"
DISPLAY, OR IF IT IS FOR A FIRE ZONE,
CALL FOR SERVICE IMMEDIATELY.
