DESCRIPTION
The AnaLASER® II High Sensitivity Smoke Detector consists of a laser particle counter detector head, a high-efficiency fan module and a termination board. One AnaLASER
II Detector, when connected to a pipe network designed
using “SNIFF” Version 3 software, provides coverage for
an area up to 20,000 sq. ft.
The AnaLASER II Detector is available in two sensitivity
ranges. The standard AnaLASER II Detector (with a dynamic
sensitivity range of 0.00075% to 0.3%/ft.) is designed for
early warning smoke detection applications such as telecommunications facilities, data processing facilities, museums and warehouses. For cleanroom applications where
the environment must be virtually free of air particulate,
Fenwal developed the Ultra™ AnaLASER II Detector that
is five times more sensitive than a standard high sensitivity
smoke detector. The Ultra AnaLASER II Detector has a
sensitivity range of 0.00015% to 0.03%/ft.
WHY HIGH SENSITIVITY SMOKE
DETECTION?
AIR SAMPLING PIPE NETWORK
The AnaLASER II Detector’s laser particle counter detects
particles of combustion at levels of obscuration as low as
0.00015%/ft. This is sensitive enough to detect invisible
products of combustion such as the outgassing of plasticizers from overheating PVC wire insulation and electrical components, or small changes in the ambient level of obscuration
during the incipient stage of a fire.
When a combustible material reaches it’s ignition temperature, the combustion becomes self-sustaining and is called
a fire. At temperatures much below the ignition temperature, chemical reactions generate airborne particles. This
is typically called the incipient stage of a fire and is followed
by visible smoke, flame and finally an intense heat stage.
Detection during the incipient stage allows time for corrective action, possibly preventing an escalation of the fire condition, and thus minimizing fire damage.

INCIPIENT STAGE
FLAME
The air sampling pipe network is a system of pipes extended
into the protected area with strategically placed sampling
holes. The UL Listed/FM Approved “SNIFF” Version 3 computer program is used to dynamically balance the pipe network. The “SNIFF” program allows greater flexibility in pipe
configuration and balances the pipe network to insure equal
sensitivity at each sampling hole. Each sample hole may
be considered an equivalent spot-type detector with a maximum coverage of 900 sq. ft. to provide UL Listed Open
Area Protection (see datasheet 89.256).
The AnaLASER II product line offers an array of air sampling network accessories such as a sampling point, capillary tube rolls, sampling point, port and pipe labels.

PARTICLE SIZE
DISCRIMINATION = NO FILTER!
The AnaLASER II Detector uses a high-efficiency centrifugal fan to draw air continuously from the protected area,
into a piping network and through the detector head, without filtration or flow restriction. As a result, filter maintenance
and loss of sensitivity due to filter clogging is eliminated.
Smoke concentration is determined by counting the number of discrete particles of a specific size in a given time
period. The Detector’s particle size discrimination feature
allows only a specific range of particle sizes (between 0.01
and 10 microns) to be measured and counted as products
of combustion. Anything above or below this range is generally ignored and does not contribute to smoke signal calculations. This discrimination band corresponds to the center
of the range of all particles of combustion. Dust particles,
which are typically larger than 10 microns, are ignored.

FEATURES
DISPLAY OPTIONS:
The AnaLASER II Detector has two display options: a status LED faceplate or a Display Module. The status LED
faceplate is a plastic molded insert with a tri-color LED that
indicates an Alarm, Pre-Alarm or Trouble condition. The
standard configuration of an AnaLASER II Detector has an
installed status LED faceplate. The LED reports the following conditions:
CONTINUOUS GREEN..................

For applications where a user interface at the Detector is
necessary, Fenwal offers an optional Display Module with a
backlit LCD screen. The Display Module allows the user to
browse through more detailed information such as protected
area smoke levels, sampling pipe airflow rate and selected
configuration settings. The optional display module also allows limited detector control functions such as reset, test
and isolate. The Display Module can be integrated into the
AnaLASER II Detector or externally mounted away from the
Detector (see datasheet 89.251).
FIRE ALARM PANEL INTERFACE:
The AnaLASER II Detector was designed with the flexibility
to interface with any fire alarm control panel. There are four
different configurations to choose from depending on the
type of control panel and the number of Detectors in the
system.
The Intelligent Interface Module (IIM) was designed to interface a large AnaLASER II Detector network to a
FenwalNET™ 2000 control panel. The IIM is an easy-toinstall module that plugs into the I/O motherboard assembly inside the FN-2000. Up to 127 AnaLASER II Detectors
can be networked together with an IIM. A computer running
LaserNET™ Version 3 software can communicate with the
IIM, either with a local computer or from a remote computer using a modem. This allows all networked AnaLASER II Detectors to be monitored and configured from a
central location and saves on installation and maintenance
costs (see datasheet 89.253).
For smaller networks connected to a FN-2000 control panel,
the AnaLASER II Detector can be connected to the addressable loop of the FN-2000 using an AnaLASER Interface
Module (AIM). The AIM is a circuit board that plugs into an
AnaLASER II Detector. With an AIM, the AnaLASER II Detector operates as one of up to 255 SmartOne® devices on
the addressable loop (see datasheet 89.252).
The AnaLASER II Detector can also interface to other fire
alarm control panels by using relay contacts inside the Detector. Each AnaLASER II Detector is equipped with six relays (Pre-Alarm 1, Pre-Alarm 2, Alarm 1, Alarm 2, Trouble,
and Isolate) which allows the Detector to directly interface
with the control panel.
Detectors that interface to a fire alarm control panel with
relays can also be networked together with a Stand-Alone
IIM. This allows up to 127 AnaLASER II Detectors to be
monitored and configured from a central location. The StandAlone IIM has the same features as the FN-2000 mounted
IIM except for the FN-2000 interface (see datasheet 89.254).
CONFIGURATION:
The AnaLASER II Detector is configured with LaserNET™
Version 3 software. To configure the Detector, a computer
running LaserNET software is connected via a programming cable to the RS-232 jack located on the side of the
Detector. LaserNET provides the ability to monitor, configure and download history from the Detector. The advanced
signal processing software features of the Detector allow
the response of the detector head to be tailored to the environment it is installed in. This provides the most sensitive
detection with a minimum of unwanted alarms (see
datasheet 89.255).
• Two Pre-Alarm and Two Alarm Levels – Programmable
in increments of 5% of the Detector’s selected output.
Alarm Level 2 and Pre-Alarm Level 2 are optional.
•
•
•
•
Day/Night Alarms – A second set of programmed alarm
levels is available for the night period which allows the
Detector’s response to be more sensitive during the
day.
Alarm Delays – Programmable from 0 to 60 seconds
for each alarm level. The delays can be used to eliminate unwanted alarms caused by transient conditions.
Alarm Latching – An option which allows alarm conditions to remain latched until reset, or to automatically
reset after a programmable delay of 0 to 60 minutes.
Smoke Signal Averaging – An option that averages the
smoke level over a programmable 2, 4, or 8 second
period. This may be used to eliminate spikes in the
smoke level caused by transient smoke.
AUTO-SETUP™ FEATURES:
Automatically sets the AnaLASER II Detector’s optimal
alarm sensitivity threshold at the time of installation. The
Auto-Setup learning time period can be set for fifteen minutes to two weeks.
HISTORY REPORTING FEATURES:
• Smoke Level History – A powerful diagnostic feature of
the Detector. Up to four weeks of date and time stamped
smoke history (40,320 data collection points) may be
stored in the Detector. History sampling rate is programmable from 1 to 60 seconds. Using LaserNET software,
this history can be retrieved and graphically displayed,
printed or stored to disk.
• Event History – Stores up to 128 events such as alarm
or trouble activations, configuration changes or operator actions. Using LaserNET software, this history can
be retrieved and displayed, printed or stored to disk.
This feature aids in the analysis of trouble or alarm incidents.
EASE OF INSTALLATION AND MAINTENANCE:
The AnaLASER II Detector is designed for ease of installation and maintenance. The Detector’s main components
can be serviced without removing the Detector’s enclosure,
conduit, inlet or exhaust pipe. The Detector can be surface-mounted by four #10 mounting holes in the back of
the Detector or by an optional flush mount trim ring.
POWER SUPPLY OPTIONS:
The AnaLASER II Detector has four different power supply
configurations. The Self-Contained Power Supply is designed to provide 24 Vdc power to a Detector from 120 or
240 Vac (see datasheet 89.258). For systems with multiple
AnaLASER II Detectors, a Multi-Zone Power Supply can
provide 24 Vdc power for up to eight Detectors from 120 or
240 Vac. The Multi-Zone Power Supply is also available
with a 48 Vdc to 24 Vdc power converter (see datasheet
89.257).
Detectors can also have 24 Vdc power supplied by the fire
alarm control panel or any listed or approved power supply.
