Installation/Wiring Instructions
Model ILP-2 Detector
These instructions are written in accordance with the
installation guidelines of NFPA No. 72, NATIONAL FIRE
ALARM CODE.
CAUTION
Detector Device Storage
DO NOT install this detection device until all construc-
tion is completed.
DO NOT store this detection device where it can be
contaminated by dirt, dust, or humidity.
DETECTOR PLACEMENT
Although no specific spacings are set for the detectors
used for the 0 to 4000 ft/min clean air velocity applica-
tion, use 30 foot center spacing (900 sq ft), from NFPA
Standard 72 as a guide or starting point for a detector
installation layout. This spacing, however, is based on
ideal conditionssmooth ceiling, no air movement, and
no physical obstructions. In some applications, there-
fore, considerably less area is protected adequately by

each smoke detector. This is why it is mandatory to
closely follow the installation drawings. In all installations
place the detector on the ceiling, a minimum of 6 inches
from a side wall, or on a wall, 6 inches from the ceiling.
If you have any questions regarding detector placement,
follow the drawings provided or approved by Cerberus
Pyrotronics or by its authorized distributors. This is
extremely important! The detector placements shown on
these drawings were chosen after a careful evaluation
of the area that is protected. Factors such as air currents,
temperature, humidity, pressure, and the nature of the
load were carefully considered. Especially noted were
the room or area configuration and the type of ceiling
(sloped or flat, smooth or beamed). Cerberus Pyrotron-
ics extensive experience in the design of the system
assures the best detector placement. Sound engineer-
ing judgment by qualified personnel must be followed.

To avoid nuisance alarms:
Do not locate the detector next to an oil burner,
electric heaters, kitchens, or garages where exhaust
smoke can trigger an alarm. Other causes of false
alarms are dust accumulation, heavy concentrations
of steam, heavy pipe or cigar smoking, high relative
humidity or other humid areas where condensa-
tion may occur, and concentrated aerosol sprays.
AIR CURRENTS
Before a detector can sense a fire, the products of com-
bustion or smoke must travel from the fire to the detector.
This travel is especially influenced by air currents;
therefore, consider air movement when designing the
system. While combustion products tend to rise, drafts
from hallways, air diffusers, fans, etc., may help or hinder
the travel of combustion products to the detector. When
positioning a detector at a particular location, give
3

consideration to windows and doors, both open and closed,
to ventilating systems, both in and out of operation, and to
other factors influencing air movement. Do not install a
detector in the air stream of a room air supply diffuser. It is
better to position a detector closer to an air return. The
distance that products of combustion or smoke travel from
a fire to the detector is not usually the shortest linear route.
Combustion products or smoke usually rise to the ceiling,
then spread out. Average ceiling heights of 8 to 10 feet do
not abnormally affect detector response. High ceilings,
located in churches, warehouses, auditoriums, etc., do
affect detector response and should be considered.
SPECIAL CEILING CONSTRUCTION FACTORS
Ceiling obstructions can change the natural movement of
air and combustion products. Take obstructions created by
girders, joists, beams, air conditioning ducts, or architec-
tural design into consideration when determining area
protection. Consider girders, joists, or beams 8 inches or
less in depth equivalent to a smooth ceiling in view of the
spillover effect of smoke. If obstructions are over 8 inches
in depth, movement of heated air and smoke may be
slowed by the pocket or bay formed by the girders, joists, or
beams. In this case, reduce spacing. If obstructions exceed
18 inches in depth and are more than 8 foot centers, treat
each bay as a separate area requiring at least one detector.

TEMPERATURE  HUMIDITY  PRESSURE 
AIR VELOCITY
The temperature range for the ILP-2 detector is from
32°F (0°C) to 100°F (38°C). Use the detector in environ-
ments where the humidity does not exceed 93% (non-
condensating). Normal changes of atmospheric pressure
do not affect detector sensitivity. The air velocity range is
0-4000 ft/min for open area applications.
ILP-2 Air Duct Applications
IMPORTANT NOTE
In Air Duct applications, the ILP-2 minimum
smoke sensitivity indicated on the nameplate is
2.5%/ft. For application/sensitivity setting, refer
to the MXL/MXLV OPERATION, INSTALLATION,
AND MAINTENANCE MANUAL, P/N 315-092036, or
the MXL-IQ OPERATION, INSTALLATION, AND
MAINTENANCE MANUAL, P/N 315-093624, as
applicable.
In Air Duct applications, the Model ILP-2 requires Air Duct
Cover P/N 305-093076. Do not use the Model
ILP-2 with any other air duct covers. The air duct cover
part numbers are located on the air duct cover flange
near the sensitivity test jack trap door.
When installing the ILP-2 in existing installations, order a
new ILP-2 Air Duct Cover Kit DA-303, P/N 500-093078 and
use it in that installation. This kit includes the required cover.

DETECTOR MOUNTING
To ensure proper installation of the detector into the base,
be sure the wires are properly dressed:
1. Position all wires flat against the base.
2. Take up all slack in the outlet box.
3. Route wires away from connector terminals.
4. When mounting the detector base, and routing wires
through the cutouts in the air shield, make sure the
shield is sealed against air leaks. Open the shield
cutouts only as much as required.
INSTALLATION OF DETECTOR HEAD
1. Align notch in detector cover to raised surface on outer
ring of base; refer to Figure 2.
2. Push detector into base and rotate clockwise to make
electrical connections. The detector automatically
stops and locks into place.
3. To remove, push detector up
into the base while rotating
the detector counterclock-
wise. Continue to rotate
counterclockwise until stop is
reached; then pull downward
to disengage from base.

PROGRAMMING
Each detector on a loop must be programmed to
respond to a unique system address.
1. To program the detector address, use the Cerberus
Pyrotronics Model FPI-32 Programmer/Tester. Refer
to the FPI-32 OPERATIONS MANUAL, P/N 315-090077.
NOTE: If using FPI-32 with Revision 1.3 software,
use system selection 2=MXL.
2. Record the loop and device number (system ad-
dress) for the detector on the detector label and on
the base to prevent installing the detector in the
wrong base.
DETECTOR/SYSTEM CONFIGURATION
ILP-2 with MXL Control Panels
When the ILP-2 is used with MXL/MXLV/MXL-IQ
systems, it can be programmed to optimize environmen-
tal response using Application Specific Detection (ASD).
All parameters, such as Sensitivity, Pre-Alarm and
Cerberus Pyrotronics new Advanced Enviromental
Algorithms are downloaded to the detector from the MXL
control panel. For air duct applications, the proper ASD
application (DUCT) must be selected. Refer to the MXL/
MXLV OPERATION, INSTALLATION, AND MAINTE-
NANCE MANUAL, P/N 315-092036, or the MXL-IQ
OPERATION, INSTALLATION, AND MAINTENANCE
MANUAL, P/N 315-093624, as applicable.

IMPORTANT NOTE
In Air Duct applications, the ILP-2 minimum
smoke sensitivity indicated on the nameplate is
2.5%/ft. For application/sensitivity setting, refer
to the MXL/MXLV OPERATION, INSTALLATION,
AND MAINTENANCE MANUAL, P/N 315-092036, or
the MXL-IQ OPERATION, INSTALLATION, AND
MAINTENANCE MANUAL, P/N 315-093624, as
applicable.
TESTING AND SENSITIVITY MEASUREMENT
Only qualified service personnel should test. The minimum
test schedule may be found in the current edition of NFPA
72, Chapter 7.
ILP-2 with MXL Family Control Panels
The MXL Control Panel must be placed into "TEST"
mode. Refer to the MXL/MXLV OPERATION, INSTALLA-
TION, AND MAINTENANCE MANUAL, P/N 315-092036
or the MXL-IQ OPERATION, INSTALLATION, AND MAIN-
TENANCE MANUAL, P/N 315-093624, as applicable. The
detector sensitivity indicated by the MXL Control Panel
should fall within the range on the detector nameplate
label. If not, refer to DETECTOR CLEANING below.

IMPORTANT
If the MXL/MXLV/MXL-IQ is connected 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 and re-arm the system at completion of servic-
ing. Notify facility personnel that the system is being
serviced so that any alarm soundings can be ignored
during the period of service.
The ILP-2 detector can also be tested using the
FPI-32 Programmer/Tester. Refer to the OPERA-
TIONS MANUAL, P/N 315-090077.
DETECTOR CLEANING
System MXL automatically indicates the trouble mes-
sage 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 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.
MAINTENANCE
The recommended requirement for detector maintenance
consists of the annual cleaning of dust and debris from
the detector head. Cleaning program intervals should be
geared to the individual detector environment.

CLEANING PROCEDURE
1. Notify the proper building personnel that the fire
alarm system is being serviced.
2. Remove the detector being cleaned from its base
and remove the detector cover. Place the detector
assembly on a flat surface with the photochamber
visible and accessible.
3. To clean the cover, carefully use a small brush or
blow any additional dust from the cover.
4. (Refer to Figure 3.) Remove the lower section of
the photo-chamber by gently squeezing the sides
to disengage the locking tabs and then pulling the
lower section out.
5. Use a small soft brush to loosen dust in the
crevices. Vacuum any dust from the lower
photochamber. Do not use cleaners or solvents on
the lower photochamber. Another method for
cleaning the photochamber after removing the
lower section is to blow out the dust. However, do
not use compressed air that might contain oils.
When not used properly, some commercially
available compressed gas cleaning canisters
(those used on computer equipment, for example)
disperse liquid instead of gas. If these products
are used in cleaning, be careful that no liquid
deposits occur, since such deposits will perma-
nently alter detector sensitivity.
6. Clean the upper photochamber by repeating the
procedures used in Step 3, observing same
precautions.

Disassembling of the Photochamber
7. (Refer to Figure 3.) Replace the lower
photochamber by aligning the locking tabs and
gently pressing the chamber into position.
8. Replace the cover of the detector assembly,
positioning the visible LED correctly. Replace the
detector in the base.
9. Clean all other Model ILP-2 detectors following
Steps 2 through 8.
10. Recheck the sensitivity of the detector.
11. If the sensitivity of the detector is still outside the
limit shown on the nameplate, replace it with a
new one and return the defective detector to the
factory for repair.
12. Notify building personnel that the system is
reactivated.

CAUTION
No field repair of the detectors should be attempted.
The detectors are factory repairable only.
