IMPORTANT
If the XL3, IXL (ICON-1), or MXL/MXL-IQ is con-
nected to a Fire Department, etc., or activates
an external system (fire extinguishing, etc.),
disarm the appropriate outputs before servicing
to prevent activation. (Refer to the appropriate
manual for the procedure.) Be sure to reset the
system at completion of servicing. Notify facility
personnel that the system is being serviced so
that any alarm soundings can be ignored during
the period of service.
The ILI-1 Series detectors can also be tested using the
FPI-32 Programmer/Tester. Refer to the OPERATIONS
MANUAL, P/N 315-090077.
DETECTOR CLEANING
Both System XL3 and the MXL/MXL-IQ Control Panel
automatically indicate the trouble message INPUT
DEVICE REQUIRES SERVICE for any detector whose
smoke sensitivity increases to the level where normally
low levels of smoke generate an alarm. (Refer to the
appropriate Manual for further explanation.) In such
circumstances, the detector may require cleaning as
a result of dust accumulation; follow the CLEANING
PROCEDURE steps described below.

CLEANING PROCEDURE
Clean by lightly brushing all open slots and by using
the suction of a vacuum cleaner. Because the suction
may cause the detector to alarm, it is recommended
that power to the detector be disconnected during
cleaning.
The detectors are not designed for thorough cleaning
in the field. When the detector sensitivity falls outside
the acceptable limits for that detector, the detector
head should be replaced by an acceptable head and
the removed head forwarded to the nearest Siemens
Building Technologies, Inc. Authorized Service Center
for servicing.
CAUTION: UNDER NO CIRCUMSTANCES IS THE
DETECTOR HEAD TO BE DISASSEM-
BLED. NO FIELD REPAIRS SHOULD BE
ATTEMPTED. THE DETECTORS ARE
FACTORY REPAIRABLE ONLY.
