Trouble Conditions
"Check" and The word CHECK on the keypad's display, accompanied by a
"Battery" Displays "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. 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 (security code plus OFF key) twice. If the display persists, CALL FOR SERVICE.
Note: A display of CHECK 70 on Alpha Display keypads indicates that the wiring connection to the external sounder is at fault (opened or shorted), and you should CALL FOR SERVICE. See “BELL FAILURE” on next page. A display of CHECK 90 indicates that RF interference may be impeding the operation of wireless sensors* in the system. See “Rcvr Jam” on next page.
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 wireless receiver from receiving | |||
| messages from a particular sensor. CALL FOR SERVICE if this | |||
| occurs. | |||
| * Not all systems use wireless sensors. | |||
| IF YOU CANNOT CORRECT A "CHECK" DISPLAY, | |||
| CALL FOR SERVICE. | |||
