ILI-1AH Smoke and Fire Detector
These instructions are written in accordance with the installation guidelines of NFPA No. 72, National Fire Alarm Code, and CAN/ULC-S524, The Installation of Fire alarm Systems.
CAUTION
Detector Storage
DO NOT install the detector until all construction 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 300
ft/min clean air velocity application, use 30 foot center spacing (900 sq ft)
from NFPA 72, National Fire Alarm Code, Chapter 5, if practical, 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, therefore, 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 (except in
special circumstances, such as in computer room underfloor where the velocity
may be up to 1200 ft/min) place the detector on the ceiling, a minimum of 12
inches from a side wall, or on a wall, 6 inches from the ceiling.
If you have questions regarding detector placement, follow the drawings
provided or approved by Siemens Building Technologies, Inc. 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 fire load were carefully considered.
Especially noted were the room or area configuration and the type of ceiling
(sloped or flat, smooth or beamed). Siemens Building Technologies, Inc.’s
extensive experience in the design of the system assures the best detector
placement by following these drawings. Sound engineering judgment by qualified
personnel must be followed.
Fire Safety
TO AVOID NUISANCE ALARMS WITH THESE DETECTORS:
DO NOT LOCATE the detectors next to an oil burner, kitchen, or garage
where exhaust fumes can trigger an alarm. Other causes of nuisance alarms are
dust accumulation, heavy concentrations of steam, heavy pipe or cigar smoke,
aerosol sprays, high air velocity, or in an area of prolonged high relative
humidity where condensation occurs.
NOTE: Except in the case of the ILI-1A and ILI-1AH where the detector can be used for high air velocity applications of up to 1200 feet per minute.
AIR CURRENTS
Before a detector can sense a fire, the products of combustion or smoke must
travel from the fire to the detector. Since their travel is influenced by air
currents, consider the movement of air in the design of 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, consider the position of
windows and doors, both open and closed, and air movement. Never 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. With an average ceiling
height (8 to 10 feet), this is not an abnormal factor. However, with high
ceilings such as in churches, ware- houses, auditoriums, etc., consider the
height.
SPECIAL CEILING CONSTRUCTION FACTORS
Ceiling obstructions can change the natural movement of air and combustion
products. Depending on the direction of smoke travel, joists and beams can
slow the movement of heated air and smoke, while pockets between them can
contain a reduced level of smoke. Take obstructions created by girders,
joists, beams, air conditioning ducts, or architectural design into
consideration when determining area protection.
Refer to the Initiating Devices chapter of NFPA Standard 72 for Location and Spacing requirements for specific types of construction; e.g. beam, suspended, level, sloped and peaked ceilings.
TEMPERATURE AND HUMIDITY
The temperature range for the ILI-1 Series is 32°F (0°C) to 100°F (38°C). The
four models can each be used in environments where the humidity does not
exceed 93% (non-condensing).
PRESSURE
Normal changes of atmospheric pressure have a negligible effect on detector
sensitivity. However, the lower air pressure at higher altitudes does have
some effect on the sensitivity of ionization type detectors.
Refer to the following table.
APPLICATIONS
Model| Velocity Range (ft/min)| Altitude Range (feet)|
Application
---|---|---|---
ILI-1| 0-300| 0-4000| Open area
ILI-1H| 0-300| 3000-8000| Open area
ILI-1A| 0-1200| 0-4000| Open area/Computer facilities/ Air duct spots
ILI-1AH| 0-1200| 3000-8000| Open area/Computer facilities/ Air duct spots
SPECIAL NOTE – HIGH STOCKPILING
In general, detector placement for high stockpiling requires closer spacing,
depending on the nature of the stock, its stored height, and the height of the
building.
Newer technologies recommend additional detector locations at tiered, lower
levels. Detector placement for this type hazard requires a judgment factor
that can only be provided by experienced, qualified personnel.
DETECTOR WIRING
Siemens Building Technologies, Inc. detectors should be interconnected as shown in Figure 1 and wired to the control panel by following the Wiring Diagram installed on the inside face of the control panel or in the Control Panel Manual provided. Note any limitations on the number of detectors permitted on each circuit.
DETECTOR MOUNTING
The detector has a separate base which attaches to a standard 4 inch square,
4-11/16 inch square, 4 inch octagonal, or single gang outlet electrical box.
The depth of the box is determined by the NEC for the number and size of the
conductors used. A finishing trim ring (Model RA-ADB) is available for bases
using a 4 inch square box.
TO MOUNT:
- Route all wires outward from outlet box.
- Place the detector so that the ALARM LED is normally visible by positioning the LED mark in the base in the necessary direction. (See Figure 2.)
- Mount base to outlet box and route wires through the hole in the center of the base. Make connections directly to the base terminals. Refer to Figure 1 for details.
- 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 cutouts only as much as required.
- Remove factory installed jumper in base between terminals 1a and 1b.
Note: To ensure proper installation of the detector head into the base,
check that the wires are properly dressed at installation.
a. Position all wires flat against the base.
b. Take up all slack in the outlet box.
c. Route wires away from connector terminals.
INSTALLATION OF DETECTOR HEAD
- Align notch in detector cover to raised surface on outer ring of base (See Figure 3).
- Push detector head into base and rotate clockwise to make electrical connections. The detector automatically stops and locks into place.
- To remove, push detector head up into the base while rotating the detector head counterclockwise. 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.
- To program the detector address, use the SIEMENS Model FPI-32 Programmer/Tester. Refer to the FPI-32 OPERATIONS MANUAL, P/N 315-090077.
- Record the loop and device number (system address) for the detector on the detector label.

IMPORTANT
If the XL3, IXL (ICON-1), or MXL/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 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 DISASSEMBLED.
NO FIELD REPAIRS SHOULD BE ATTEMPTED. THE DETECTORS ARE FACTORY REPAIRABLE
ONLY.
