The Cerberus Pyrotronics ILP-2 Intelligent Photoelectric
Smoke Detector offers the life safety industry the most
advanced method of detection and communication
available today. The ILP-2 utilizes advanced algorithms that
allow the detector to distinguish deceptive phenomena
while optomizing response to actual hazards / fires such
as that from a cigarette or motor vehicle in a parking
garage from an actual fire hazard. In addition, the ILP-2
detector provided an extremely high degree of resistance
to RFI, EMI, and humidity. No other detection system
available today offers a higher level of protection or false
alarm immunity. The ILP Series detector uses a state-ofthe-art Motorola microprocessor with “on-board” EEPROM
with error checking and supervision algorithms.
The ILP Series intelligent photoelectric detectors are
compatible with Cerberus Pyrotronics’ SensorLINK FPI-32
field programmer/tester. The FPI-32 is a compact, portable, menu-driven accessory which makes programming
and testing detectors faster, easier and more reliable than
other methods. The FPI-32 eliminates the need for cumbersome, unreliable mechanical programming methods
and reduces installation and service costs by electronically
programming addresses and functionally testing the ILP’s
performance before the detector is installed.
The ILP-2 photoelectric detector is compatible with
Cerberus Pyrotronics’ MXL and MXLV control panels.
All ILP Series detectors are Underwriters Laboratories
Descri ption
The ILP-2 is a plug-in, two-wire photoelectric detector,
compatible with Cerberus Pyrotronics’ MXL or MXLV
systems. Each ILP-2 detector consists of a dust resistant,
field cleanable photo chamber, microprocessor based
electronic circuitry with plastic cover and base. Electronic
component packaging uses surface mount type technology. The entire electronic assembly is fully protected from
noise transients by shielding and is coated to resist
moisture and corrosion.
The ILP-2 photoelectric detector utilizes a light emitting
diode (LED), and light sensing photodiode assembled in a
fixed array so that under normal conditions, light transmitted by the LED is directed away from the photodiode and
scattered throughout the smoke chamber in a controlled
pattern. The smoke chamber is designed to manage light
dissipation and extraneous reflections from dust particles
or other non-smoke airborne contaminants in such a way
as to maintain stable, consistent detector operation.
The Cerberus Pyrotronics ILP-2 detector provides the
highest level of detector intelligence available today with a
detector / panel link that allows the user to program the
detector for specific fire hazard profiles through simple
software selection. When installing a new ILP-2 detector,
the user simply selects the application from the following
Warehouse/Light Manufacturing
Computer Room
Parking Garage
Utility/Transformer Room
Hostile Environment
Precious Storage / Air Duct
The software does the rest; no guessing on percent of
obscuration or selecting outdated alarm configuration
delay figures; the control panel programs the detector for
the optimum fire protection mode without hassle and
without confirmation delays. Once optimized for the fire
hazards in the area, the ILP-2 provides the best detection
you can buy. Should the operator or installer forget to
program the detector, the detector will revert to a default
setting that allows it to operate as a standard photoelectric
The ILP-2 detector’s microprocessor uses an integral
EEPROM to store the detector’s address, and other critical
operating parameters which include an assigned, programmable value for alarm and trouble thresholds.
The microprocessor’s software employs sophisticated,
proprietary algorithms to identify and disregard false
alarms caused by radio frequency (RFI) and electromagnetic (EMI) interference and also validates all trouble
conditions before annunciating or reporting to the control
panel. Communications within the detector itself and also
between the ILP-2 detector and the control panel or the
FPI-32 programming accessory are supervised and
safeguarded against disruption by reliable, microprocessor
based error checking routines. Additionally, the microprocessor supervises all EEPROM memory locations and
provides a high degree of EEPROM failure fault tolerance.
In MXL or MXLV applications, an ILP series detector
determines it’s operating status to be normal, in alarm, or
in trouble depending on the difference between the alarm
threshold value stored in the detector’s memory and the
detector’s latest analog measurement. The detector then
communicates changes in its status to the MXL or MXLV
control panel. In addition, MXL and MXLV panels will
periodically sample the value of the detector’s analog
signal in order to determine if those values indicate
excessive dust buildup in the photo-chamber; if so the
MXL(V) will indicate that the particular detector requires
When an ILP series detector’s alarm condition is confirmed
by the control panel, the detector’s LED flashes and
continues flashing until the system is reset at the control
panel. Also, any user defined system alarm function or
control by event functions are activated. Each ILP series
detector is capable of operating one “I” series remote
alarm indicator, or one auxiliary relay, or one audible base.
Detector sensitivity, calibration and identification are
dynamically supervised by the control panel. Detector
sensitivity can be changed from the control panel.
The SensorLINK FPI-32 Program/Test accessory is used to
program and verify the detector’s address. The technician
selects the accessory’s program mode to enter the desired
address. The FPI-32 will then automatically set and verify
the address and test the detector. The FPI-32 operates on
AC power or rechargeable batteries, providing the flexibility
and convenience to program and test detectors anywhere.
When in the test mode, the FPI-32 will perform a series of
diagnostic tests on the ILP detectors without altering the
address, allowing technicians to determine if the detector
is operating properly or not.
The ILP series detectors may be installed on the same
initiating circuits with ID-60 series detectors, MSI series
manual boxes, TRI series interfaces, ICP output control
devices or the CZM series conventional zone modules.
All ILP series detectors can be cleaned in the field as
required by simply removing first the detector cover, then
the photo chamber cover and cleaning the interior surfaces of the photo chamber with a clean, soft cloth or
The ILP series detectors use the Cerberus Pyrotronics low
profile surface mounting detector bases. Detector base
model DB-3S mounts to a 4-inch octagonal, square or
single gang electrical box. Relay base model DB-X3RS
mounts to a 4-inch square deep electrical box. Audible
base model ADBI-60 mounts to a 4-inch square deep
electrical box. When a 4-inch square or 4-inch square
deep electrical box is used, an optional trim ring is available; model RA-ADB. The DB-3S, DB-X3RS and ADBI-60
bases use screw clamp terminals for all electrical connections and self-wiping contacts for increased reliability.
These bases contain a provision for an optional, concealed
locking mechanism, model DB-LK, to prevent unauthorized removal of the detector head.
All ILP series photoelectric detectors are approved for
operation within the U.L. specified temperature range of
0°C and 38°C.
Applications Data
Installation of the ILP series of photoelectric detectors
requires a two-wire circuit of 18 AWG thermoplastic fixture
wire enclosed in conduit, or 18 AWG limited energy,
shielded cable without conduit if permitted by local building codes. Field wiring should conform to local and
National Electric Codes, and to the control panel wiring
“T-tapping” is permitted only for Style 4 (Class B) wiring.
ILP series photoelectric detectors can be applied within the
maximum 30 foot center spacing (900 sq.ft. area) as
referenced in NFPA 72. This applications guideline is
based on ideal conditions, specifically; smooth ceiling
surfaces, minimal air movement, and no physical obstructions between potential fire sources and the detector. Do
not mount detectors in close proximity to ventilation or
heating and air conditioning outlets. Exposed joists or
beamed ceilings may also affect safe spacing limitations
for detectors. Should questions arise regarding detector
placement, observe NFPA 72 guidelines.
