TROUBLE CONDITIONS

 

 Not all systems use

wireless sensors.

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 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.
