Chapter 1: Introduction
4 Stratos EX Hazardous Area Aspirating Smoke Detection System Installation Manual
Do not install electronic assemblies prior to mounting and attaching conduit for
field wiring to the enclosure. Before making modifications, verify that they will not
interfere with battery and printed circuit board locations. Do not overtighten screw
terminals. Overtightening may damage threads, resulting in reduced terminal
contact pressure and difficulty with screw terminal removal.
This system contains static-sensitive components. Always ground yourself with a
proper wrist strap before handling any circuits so that static charges are removed
from the body. Use static suppressive packaging to protect electronic assemblies
removed from the control unit.
Follow the instructions in this manual. These instructions must be followed to
avoid damage to the control unit and associated equipment. System operation
and reliability depend upon proper installation.
Caution: While installing a fire alarm system may make lower insurance rates
possible, it is not a substitute for insurance. An automatic fire alarm system or
components of a system—smoke detectors, heat detectors, manual pull stations,
notification appliances, and a fire alarm control unit with remote-notification
capability—can provide early warning of a developing fire. Such a system,
however, does not assure protection against property damage or loss of life
resulting from a fire.
Aspirating smoke detection system
limitations
An aspirating smoke detection system—which can be made up of smoke
detectors, heat detectors, manual pull stations, notification appliances, and a fire
alarm control unit with remote-notification capability—can provide early warning
of a developing fire. Such a system, however, does not assure protection against
property damage or loss of life resulting from a fire.
Any fire alarm system may fail for a variety of reasons. The following are only
examples:
• Smoke detectors may not sense fire where smoke cannot reach the
detectors, such as in chimneys, in walls, on roofs, or on the other side of
closed doors.
• Smoke detectors on one level also may not sense a fire on another level or
floor of a building. A second floor detector, for example, may not sense a first
floor or basement fire.
• All types of smoke detectors—ionization, photoelectric and air aspirating—
have sensing limitations. No type of smoke detector can sense every kind of
fire caused by carelessness and safety hazards such as smoking in bed,
escaping gas, improper storage of flammable materials, overloaded electrical
circuits, or arson.

Chapter 1: Introduction
Stratos EX Hazardous Area Aspirating Smoke Detection System Installation Manual 5
• Notification appliances, such as bells, may not alert people if these
appliances are located on the other side of closed or partly open doors, or are
located on another floor of a building.
• A fire alarm system will not operate without electrical power. If AC power fails,
the system will operate from standby batteries only for a specified time.
• Auxiliary equipment used in the system may not be technically compatible
with the control unit. It is essential to use only equipment listed for service
with your control unit.
• Telephone lines needed to transmit alarm signals from a premises to a central
monitoring station may be out of service or temporarily disabled.
• The most common cause of fire alarm malfunctions is inadequate
maintenance. All devices and system wiring should be tested and maintained
by professional fire alarm installers following written procedures supplied with
each device. System inspection and testing should be scheduled monthly or
as required by national and/or local fire codes and standards. Adequate
written records of all inspections should be kept.

Introduction
The EX detector is a highly sophisticated “next generation” high sensitivity
aspirating smoke detection product that provides all the benefits of air sampling
high sensitivity smoke detection, including very early warning. Designed for easy
installation and commissioning, the EX detector incorporates a patented “artificial
intelligence” known as ClassiFire, which allows the detector to configure itself to
optimum sensitivity, alarm thresholds, and minimum nuisance alarms for various
environments.
The EX detector operates by drawing air from a protected space via a supervised
piping network in relatively small areas. The sampled air is passed through a
“dust separator” to remove dust and dirt before entering the laser detection
chamber. Sophisticated, state of the art electronics are used to analyze the
sampled air and generate a signal representing the level of smoke present.
ClassiFire intelligence also monitors the detector chamber and dust separator
(filter) for contamination, continually adjusting the appropriate operating
parameters to counteract the negative effects of any contamination. Aspirating
smoke detectors are unique in being able to provide a consistent level of
protection in a very wide range of environments by continuously making minor
adjustments to sensitivity.
The aspirating line of detectors detects “difficult-to-detect” slow growth electrical
overload incipient fires in “difficult” environments.
This equipment is Class 111 as defined in EN 60950 (i.e., this equipment is
designed to operate from Safety Extra Low Voltages and does not generate any
hazardous voltages).
The EX detector is housed in a Groveley Engineering flameproof enclosure
(certificate No. DEMKO028TEX131598) which is fitted with Knitmesh flame
arrestors (certificate No. EPSILON06ATEX2138U) at the sample inlet and
exhaust ports. The detector features dual high pressure aspirators to overcome
the flow restriction of the Knitmesh flame arrestors and provide excellent air
sampling performance. The use of two aspirators provides an element of
redundancy as the system will continue to sample in the unlikely event of an
aspirator failure.
For ease of maintenance the air filter is mounted external to the main detector in
a separate stainless steel enclosure. The filter housing does not contain any
electrical equipment and so it can be opened for filter replacement without
compromising the flameproof protection of the system.
The light weight of EX detector (8.5kg) makes installation a simple and safe one-
man operation, with no special lifting equipment required.
The networking capabilities of EX detector permit the use of remote displays and
other standard accessories. Programming of an EX detector system can be
undertaken using the SenseNET system located in a safe area.
