Protection 1 ProtectionOne Security System 250P1 Manual Do Utilizador

The word CHECK on the keypad's display, accompanied by a rapid
beeping at the keypad, indicates a trouble condition in the system.
The displays in parentheses in the left column below may appear on
non-alpha keypads when the associated trouble condition is present.

To silence the beeping sound for “CHECK” conditions, press any
key.

CHECK + Zone
Descriptors

Indicates that a problem exists with those
zone(s). First, determine why the zone(s)
displayed are faulted (open window or door;
open or shorted zone terminals; etc.) and
correct the problem. If the zone(s) contain a
wireless detector, check that changes in the
room (moving furniture, televisions, etc.) are
not blocking wireless signals to/from the
detector. If the problem has been corrected, key
an OFF sequence (enter the 4-digit security
code, then press the OFF key) to clear the
display.

A CHECK condition can also indicate a wiring
problem (opens or shorts, for instance).  If the
CHECK display persists, CALL FOR
SERVICE IMMEDIATELY.

Note that the system will not allow arming if a
CHECK condition exists. To arm the system
with a CHECK condition present, you must
first bypass the zone(s) having the CHECK
condition.

NOTE: Zone 9 represents a problem with the
wireless receiver or other system devices,
which are not user-serviceable.
