c. Fasten the cover, using the No. 6 screws (19) provided. Tighten
snugly, but not so tightly as to warp the cover and cause air leakage
around the edges of the cover.
Sensitivity Testing
1. The sensitivity of System XL3 smoke detectors can be selected at the
system control panel. Refer to
SYSTEM XL3 OPERATION, INSTAL-
LATION, AND MAINTENANCE MANUAL,
P/N 315-083206.
2. The sensitivity of MXL Control Panel smoke detectors can be selected
at the system control panel. Reter to the
MXL OPERATION, INSTAL-
LATION, AND MAINTENANCE MANUAL,
P/N 315-092036.
3. The sensitivity of System IXL (ICON-1) smoke detectors can be
selected at the system control panel. Refer to the
IXL OPERATION,
INSTALLATION, AND MAINTENANCE MANUAL,
P/N 315-092371.
4. To ensure that the sensitivities are within factory-specified limits,
sensitivity testing of the smoke detectors should be done by qualified
service personnel only.
Maintenance
The performance of the air duct detector unit may be adversely affected
by dirt or foreign matter on the sampling tubes or detector. If the air holes
in the inlet sampling tube become restricted, the unit cannot receive a
proper air sample, and performance is impaired. It is recommended that
the sampling tubes be checked and cleaned periodically. The detector
maintenance program should consist of periodic cleaning of dust from the
detector head by using a vacuum cleaner. For cleaning Model ILP-1, refer
to the related Installation Instructions.

Detector Programming
NOTES:
1. The device number of the detector is set by inserting
program jumpers into the appropriate combinations of
address holes located on the rear of the detector.
2. The Detector Device Number Table lists the device
number, address, and jumpers required.
3. A space is provided on the detector label to record the
zone and device number for the detector.
