1 Product Description

1.1 Characteristics of the TITANUS

MICRO·SENS

detection system

aspirating smoke

TITANUS MICRO·SENS® is the latest generation of the renowned WAGNER smoke detection systems. The TITANUS MICRO·SENS be used for room and equipment protection and for monitoring air conditioning cabinets or air conditioning ducts. Through the innovative ROOM·IDENT process, the system can also locate the site of the fire.

Locating the site of the fire The unique ROOM·IDENT technology makes it possible to determine the

location of a fire when monitoring up to 5 separate areas. So that the emergency services can act as quickly as possible, the seat of the fire can be made known, for example, via reaction indicators which are allocated to the various monitoring areas.

Sensitivity The TITANUS MICRO·SENS

0.1 %/m and 2 %/m light obscuration in steps of 0.1%/m. Using a smoke

level indicator, an indicator sensitivity of between 0.05 %/m and 0.2 %/m light obscuration can be achieved. The HIGH POWER LIGHT SOURCE light source technology used in TITANUS neous reaction behaviour from different types of fire. The device can provide 2 alarm thresholds (pre alarm and alarm). The pre-alarm threshold is adjustable from 10 - 80 % of the fire alarm threshold.

Intelligent signal processing The TITANUS MICRO·SENS

processing for avoiding false alarms. Perfected algorithms based on numerous fire trials and decades of experience ensure a high level of safety in differentiating between a false status and a fire event.

Safe airflow monitoring PIPE·GUARD, the comprehensive package for airflow monitoring,

recognises safe breakdowns such as pipe breakages or blocked detection apertures. Using dynamic airflow monitoring, the TITANUS

MICRO·SENS

thus makes an important contribution to sabotage safety. Airflow monitoring is temperature-compensated and can be set to be air

pressure-dependent.

Product Description TITANUS MICRO·SENS®

Plug and Play Installation and commissioning of the TITANUS MICRO·SENS

are

simple with the Plug & Play function. The device base is pre-assembled on site. By pre-setting the detection

unit for standard applications, the TITANUS MICRO·SENS

is operational

immediately after it is inserted in the device base.

Redundancy

ventilators For maximum safety, the TITANUS MICRO·SENS

can be fitted with redundancy ventilators as an option. During operation of the device with the redundancy ventilator, ROOM·IDENT is not possible.

Network capacity Fitted with a network card, several TITANUS MICRO·SENS® devices can

be linked together in an Ethernet network. From a central point the user can, for example, via VisuLAN T levels, airflow values etc. In addition, the TITANUS MICRO·SENS

monitor the whole plant for smoke

can be integrated via the so-called OPC server into existing hazard and building management systems.

Potential free contacts The TITANUS MICRO·SENS

has one potential free contact each for

alarm and fault. So the smoke detection system can be switched to col-

lective and addressable (FAS). A relay card (optional) can be connected to the TITANUS

MICRO·SENS

in order to connect the potential-free contact for the pre-

recording lines of any central fire alarm systems

alarm to a detector line of a CFDU.

Diagnostics With the DIAG 3 diagnostics device, there is a system available for

commissioning, inspection and servicing which makes it possible to configure the device quickly and easily and contain faults. For diagnostics purposes events are stored in the TITANUS MICRO·SENS

for 72 hours.

Designing detection points The monitoring surfaces of the detection point type for the TITANUS

MICRO·SENS

are to be set to match the point-specific smoke alarms. The detection points can thus be designed similar to point-specific smoke alarms in accordance with the particular national regulations.

Patented detection points Wagner’s patented detection reducing films, clips and banderols make

assembly simple and comfortable and avoid whistling operational noises. An even inflow of air through all the apertures is achieved with a stepped aperture diameter. These are fitted with rapidly checkable identification.

Extensive

pipe accessories Wagner’s extensive range of accessories makes it possible to use the

TITANUS

aspirating smoke detection system even under the most difficult of conditions. Products from various types of air filter from condensate traps to blow through devices raise the serviceable life under extreme dusty, humid and excessively cold environmental conditions.

TITANUS MICRO·SENS® Product Description

1.2 Areas of Application

The TITANUS MICRO·SENS® air sampling smoke detection system is a fire alarm system for the protection of rooms, equipment and air conditioning ducts.

Principle Air samples for a monitoring area are taken through the draw-off holes in

a pipe system and fed to the detection unit. The principle is particularly suitable for areas in which point type alarms

are not used or can only be used to a limited extent. This involves areas in particular …

• where is a high risk of fire,

• where high detection sensitivity is required,

• where false alarms must be avoided,

• which are difficult to access and in which it is difficult to mount and/or

inspect point type alarms,

• where interrupting operations for inspection and servicing must be

avoided,

• which are air conditioned,

• where the height is greater than is allowed for point type alarms,

• where for aesthetic reasons point type alarms are not wanted,

• where there are strong electromagnetic fields,

• which are subjected to high or low temperatures,

• which have a heavy dust load,

• where the fire alarm equipment must be protected against vandalism

or sabotage

To guarantee safe operation even under the most difficult conditions (e.g. recycling area), there are extensive accessories available such as, e.g., an integrated air filter, various external air filters or the blow through device. In very cold areas, a deep freeze version of the TITANUS

MICRO·SENS

can be used. A redundancy ventilator can be used for

applications where there are particular safety requirements. When fitted to monitor several monitoring areas and blind spots, there

are reaction indicators for rapid identification of the seat of the fire and an offset parallel display as a status indicator for the detection unit.

MS_A_02-a-en-e Data: 01/09 2 – 1

Technical Description TITANUS MICRO·SENS®

2.1.1 Function

Air samples are taken from the area to be monitored via a pipe system with defined aspiration apertures, using the TITANUS MICRO·SENS aspiration unit and these are sent to the sensitive detection unit (see Fig.2.1).

Locating the site of the fire It is possible to locate the site of the fire using ROOM·IDENT with an I-

pipe design for a maximum 5 rooms or pieces of equipment. The operating principle incorporates four phases:

Phase 1 During operating conditions air samples are taken from the pipes cover-

ing the various rooms. The samples are taken via fan to the detector unit and analysed for possible smoke particles.

Fig. 2.2: Phase 1 ROOM-IDENT standard operation

Phase 2 The system will activate an alarm once it has reached an alarm threshold

level due to the rise of typical smoke aerosols. If « Fire alarm after ROOM·IDENT « is enabled, then the localisation process will start after an adjustable Action - Alarm threshold. The system will activate an alarm once the localisation is completed.

Fig. 2.3: Phase 2 ROOM-IDENT Earliest fire detection.

2 – 2 Data: 01/09 MS_A_02-a-en-e

TITANUS MICRO·SENS® Technical Description

Phase 3 In case alarm or at function « Fire alarm after ROOM·IDENT « once the

system has reached the adjustable action the aspiration fan is switched off and a second fan is switched on, blowing out the smoke particles in the opposite direction.

Fig. 2.4: Phase 2 ROOM-IDENT Blow through.

Phase 4 After the pipe system has been freed from smoke, the airflow is reversed

once again and the time it takes for the smoke to reach the detector unit is measured. With this time value the exact location of the smoke source is given and shows which room is affected.

Fig. 2.5: Phase 4 ROOM-IDENT Localisation.

The alarm is indicated on the TITANUS MICRO·SENS® itself, indicated within the monitored area via an optical external alarm indicator. The System with enabled option “Fire alarm after ROOM IDENT » will now activate an alarm.

Detection Depending on the reaction sensitivity of the detection unit used (which

can be 0.1 %/m to 2 %/m light obscuration or 0.5 %/m to 2 %/m light obscuration), the TITANUS MICRO·SENS

triggers the main alarm once the

corresponding light turbidity is reached. The sensitivity can be set in

MS_A_02-a-en-e Data: 01/09 2 – 3

Technical Description TITANUS MICRO·SENS®

steps of 0.1 %/m. The alarm is shown on the device via the alarm display and forwarded to a connected fire alarm system (FAS).

By changing the delay time with the diagnosis tool, the forwarding of alarms and faults can be set.

The intelligent LOGIC·SENS signal processing device serves to blank out fire-like false alarms and ensures high false alarm safety.

Airflow monitoring An airflow sensor checks the connected pipe system for breaks and

blockages. Depending on the design of the pipe system and the setting on the air-

flow sensor, the blockage of just one aspiration aperture can be picked up. The airflow monitoring is temperature-compensated and can be made air pressure-dependent.

At the end of the adjustable delay time, the fault is shown on the smoke detection system and a corresponding message is forwarded to the central fire alarm point via a contact. The monitoring windows can be adjusted to the environmental conditions.

The principle of the airflow sensor signalling process can be seen in

0HFig.

2.6 .

Device monitoring The detection unit is monitored for dirt and signal fault. Any fault which

occurs is displayed at the TITANUS MICRO·SENS

and can be for-

warded to the FAS via a contact.

is operating an FAS alarm and fault [menages] have to

be reset at the same time as the control line, then as an option a reset

can be inserted in a separate housing. The effect is that when

board there is any short-term switching off of the line voltage, the alarm and fault messages on the TITANUS MICRO·SENS

are automatically reset.

An aspiration aperture is a 10 mm hole in the aspiration pipe which is covered by a patented aspiration reduction film with the required aperture diameter. The size of the aperture depends on the pipe system design (see Chapter 4, "Design").

To prevent the aspiration reduction film coming loose, it is held in place by a banderol. The banderol is a transparent adhesive film with red edges and a 10 mm large hole. It is stuck over the aspiration reduction film in such a way that the aspiration aperture is not covered and is also visible at larger distances.

The standard type AF-x aspiration reduction films and the type AF-BR banderol’s are not suitable for use in very low temperature areas. Aspiration reduction clips are to be used in these areas instead (see Chapter

2.3.2.2).

Fig. 2.25: Aspiration reduction for dirty areas and deep freeze areas

The aspiration apertures used in areas where there may be blockages are fitted with a patented type AK-C plastic clip and a patented type AK-x flexible aspiration reduction (see

0HFig. 2.25). The aspiration reducers are

available in defined, stepped aperture diameters. With blowing through, the flexible aspiration reducer stretches to the

aspiration apertures. In deep freeze areas this leads to icing breaking off and in very dusty areas to dirt breaking off. The special plastic clip is for fixing the aspiration reduction to the pre-defined point.

When designing for areas with environmental influences which make blowing through necessary (e.g. dust) or very humid areas, the aspiration reducers with a plastic clip are to be preferred over aspiration reduction films with banderol. The plastic clips have greater resistance when subject to pressure stress. There is also a greater cleaning effect thanks to the elastic rubber insert.

Aesthetics If room monitoring requires a concealed pipe system installation, then it

can be mounted in an intermediate ceiling. Ceiling ducts into the intermediate ceiling are then used. The ceiling ducts are – in accordance with design guidelines – fitted with aspiration reduction films with defined aspiration apertures (see Chapter 4 "Design"). The ceiling ducts are then connected to the pipe system via aspiration hoses (see

1HFig. 2.26).

If the length of these hoses is a maximum 3 m, then the design according to Chapter 4 applies. If because of building circumstances lengths of

more than 3 m are required, the pipe system must be calculated

The ceiling duct can be used for intermediate ceiling boards up to about 35 mm in strength. The aspiration reduction films are available in two colours (pure white, RAL 9010 and papyrus white, RAL 9018) and also in special colours on request.

Fig. 2.27: TITANUS MICRO·SENS

with air filter

In areas with interference to the environment such as, e.g. dust, an air filter is to be used to protect the smoke detection system.

Type LF-AD-x air filter The standard air filter used is the type LF-AD-x, comprising a plastic

housing with two PG29 threaded connections. The multi-layer filter material absorbs particles which are larger than about 15 μm.

The air filter is automatically monitored for dirt (blockage) by the TITANUS MICRO·SENS

air flow monitoring arrangement. If the air filters are dirty, then the filter inserts must be changed by opening the filter housing.

Special type SF-x filter In extremely dusty areas (e.g. recycling plants) in which the use of an

LF-AD is not sufficient, a special filter must be used. The special filter safely holds back the dust particles in a heavily polluted atmosphere using the filter medium. The filter is guaranteed to have an even quality of dust collection right through to the end of its useful life. Two types of special filter are available (type SF-400 and type SF-650), the SF-650 having a longer useful life because of its larger surface area.

Fig. 2.28: Principle of air return in the TITANUS MICRO·SENS

If the TITANUS MICRO·SENS® and the pipe system are installed in two areas P1 and P2 with different air pressures, the air drawn off has to be returned to the pipe system pressure range (see

2HFig. 2.28). Returning the

air can also avoid air pollution (e.g. smells) in neighbouring rooms.

4.1.2 Pipe system

When planning the pipe system, it must be ensured that reliable fire detection is guaranteed for any fire present in an installation or in a monitored area. Fig. 4.1 depicts an example of a U-pipe system with symmetrical or asymmetrical design and the diameters of the aspiration apertures calculated according to Chapter 4.6.2 “Standard planning.”

The number of the intake apertures and the pipe system design depends on the size, ventilation and shape of the monitored area. The aspiration apertures should be planned like point-type detectors. The pipe system is to be fitted in accordance with the project planning guidelines in this section while taking the following points into consideration:

Symmetrical design The pipe system should preferably have a symmetrical design, i.e.:

• equal number of aspiration apertures per pipeline branch

• equal lengths of pipeline (must not exceed ± 20 % deviation)

• equal distance between neighbouring aspiration apertures on the

smoke aspiration pipe (must not exceed ± 20 % deviation)

Asymmetrical design The following specifications apply in the event that pipe system must be

laid out asymmetrically due to structural conditions (see also Fig. 4.1):

• The number of aspiration apertures as well as the length of the

shortest and longest pipeline branch in the pipe system must not exceed a quantity or length ratio of 1:2.

• The distances between adjacent aspiration apertures in the sampling

pipe must be identical (should not exceed deviation of ±20%).

• The diameters of the aspiration apertures are determined for each

pipeline branch individually and depend on the number of aspiration apertures on the pipeline branch in question. The commensurate aperture diameters can be found in the tables in Chap. 4.2.4.

Branch length In order to ensure a short transport time for the smoke fumes in the sam-

pling pipe and thus enable rapid detection, it is better to plan several shorter than a few long ones (preferably a U- or double U-pipe system ).

Direction change Angles and bends in the pipe system increase flow resistance. For that

reason, it is necessary to limit the number of them to the amount required.

It is preferable to use bends, since angles have a higher flow resistance. Angles should therefore only be used where they are necessary due to structural constraints.

Corresponds to a straight pipe length of

Angle 1.5m

Bend 0.3m

If the pipe system includes angles or bends, the maximum overall length of the pipe system will be reduced.

Bends are to be preferred over angles. An excessive number of changes in direction can change the detection time.

INSTRUCTION

Special cases If the pipe system does not match the project planning guidelines de-

scribed here due to structural constraints, WAGNER should make the individual calculations for such a case.

Checking Check detection reliability with activation tests in cases where use of the

system is critical. Also check whether an air flow rate is present at individual aspiration apertures.

The fan voltage can be increased in order to reduce transport time.

TIP

Make sure that the current intake increases.

4.1.3 Air flow monitoring

EN 54-20 requires the recognition of a 20 percent change in the air flow volume by the detector module’s air flow sensor system. The activating threshold of the air flow sensor system has to be adjusted to ≤ 20 % in order to achieve this. It is recommended to conduct an air pressuredependent air flow compensation for both of these settings.

Any threshold desired may be set with systems which do not require EN 54-20 conformity.

Project planning for the air flow monitoring system in sampling pipes is carried out while taking into consideration the respective national regulations for each country.

Adjusting the air flow sensitivity The air flow sensor sensitivity must be adjusted to the application in

question. Breakage and stoppages must be detected reliability with low susceptibility to malfunction.

The activating threshold and for this reason the sensitivity of the air flow sensor is continuously adjustable from 10 – 50 %.

In conformity with

EN 54-20

Triggering threshold 10 % 20 % 40 % 50 %

Sensitivity Very high High Medium Low

It is recommended to always select the greatest possible level which is permissible according to national standards.

TIP

Dynamic

air flow sensor system The device’s air flow monitoring enables the system to detect both pipe

breakages outside the device and sudden obstruction in individual aspiration apertures (e.g. in the event of sabotage to the pipe system). The dynamic air flow sensor system has been activated via the diagnostics software, the following modifications have to be regarded.

MS_A_04-en-e Data: 01/09 4 – 7

Pipe Design TITANUS MICRO·SENS®

Limitations The air flow monitoring may only be set, if:

z Project planning according to “Individual aperture monitoring” has been

carried out (see Chap. 4.3.1 “Pipe project planning individual aperture monitoring”),

z the air flow sensor has been compensated depending on the air pres-

sure (see Chap. 7.1.2 “Air pressure dependent air flow compensation") and

z No large air flow fluctuations occur.

Air pressure differences The same air pressure must be present throughout the sampling pipe.

If the air sampling smoke detection system and pipe system are in areas with different air pressure, the air sampled by the TITANUS

MICRO·SENS® should be re-circulated in the pipe system pressure

area (see Chapter 2.3.5 “Air recirculation”).

INSTRUCTION

TITANUS MICRO·SENS® with active location of the fire must be installed outside the areas to be monitored and without air return.

INSTRUCTION

ROOM IDENT cannot be used in applications with varying or not consistent air pressure levels. This is due to the fact, that under these conditions the aspirated air needs to be returned to the monitored area. Since air return is not allowed with ROOM·IDENT these applications

INSTRUCTION

cannot be served.

4.1.4 Sensitivity

According to EN 54-20, the sensitivity of a air sampling smoke detection system can be divided into particular fire sensitivity classes. These sensitivity classes describe particular example applications in which the systems can be used. Permissible system project planning can be determined for each classification according to Chapter 4.2.

Air sampling smoke detection systems with a higher sensitivity class according to EN 54-20 also meet the requirements of the lower classes.

Class Description Example application

Air sampling smoke de-

tector with very high

sensitivity

Air sampling smoke de-

tector with increased

sensitivity

Air sampling smoke de-

tector with standard

sensitivity

The fire sensitivity classes A, B and C can be achieved with each detection unit available, depending on the number of aspiration apertures.

Very early detection:

Highly diluted smoke in air

conditioned IT areas

Early detection:

Diluted smoke in conventional

cooled IT areas.

Standard detection:

Fire detection with the benefits of air

sampling smoke detection systems

4.2 Project planning

4.2.1 Project planning guidelines

In order to conduct project planning in accordance with the EN 54-20 standard, it is necessary to be familiar with particular factors. These are the requirements for the system’s sensitivity, the number of aspiration apertures and the accessories necessary for the corresponding application. The pipe system design in conformity with the standard can be determined based on these factors using the following chapter and with the help of the project planning tables in the appendix.

4.2.1.1 Determining the necessary accessories

INSTRUCTION

Since the accessory components, such as filters, have a certain influence on the dimension of the pipe planning, the suitable accessories must be selected for the corresponding application ahead of time. Retrofitting, with a fine filter, for instance, is generally only possible if a more sensitive detector module is being used or a particular reserve has been planned in advance.

Components which have not been approved by WAGNER are used, CE conformity on the basis of EN 54-20 will not be possible.

The following accessory components should be taken into consideration in the process:

z Air filters z Steam trap z VSK stop valves z Detector box z OXY·SENS

4.3.3 Design for Forced Air Flow

Monitoring air conditioning ducts Air conditioning plants are divided into low-speed and high-speed plants

(see table below). The information given in this chapter applies only to low-speed plants. There is insufficient information from experience with

high-speed plants. Where air conditioning ducts have flow speeds of more than 10 m/s, therefore, smoke testing must be carried out for the best reaction behaviour to be determined.

Low speed plants High speed plants

Flow speed maximum 6 to 10 m/s > 10 m/s

Duct cross-section large small

Differential pressures

along the flow direction

small large

The speed distribution in an air conditioning duct looks as follows:

Fig. 4.14: Speed distribution in an air conditioning duct with v

Air conditioning duct

In the outer areas of the cross-section surf ace area t he air f low i s lowest

The largest air flow is t in the centre of the cross section

> v2 > v3 > v

Aspiration To achieve optimum detection results, the pipe system must be arranged

in the area v

to v3.

Location of the

pipe system To achieve the best location for constructing the pipe system, the ex-

haust duct should be as far as possible from sound dampers, air baffle plates and kinks. The guideline figure for the distance from such “obstacles” is at least 3 x the smallest duct diameter.

If it is absolutely essential to fit the pipe system directly behind baffle plates, sound dampers or bends, the main speed areas must be monitored (see Fig. 4.15/16).

When a pipe system is built into air conditioning ducts, the following must be observed:

• As the TITANUS MICRO·SENS

and the pipe system are in different pressure areas, there must be an air return arrangement (see following page).

• The pipe entries into the duct must be sealed air-tight.

• The part of the pipe system which is outside the duct must be

bonded air-tight.

4.4 Power Supply

When sizing the power supply, the signal-ready status of the danger alarm equipment and the alarm case are considered. When the plant is in the signal-ready status, the power supply must deliver the idling current to the air sampling smoke detection systems and guarantee charging of the stand-by accus in accordance with DIN VDE 0833, Part 1

The following formulae apply in case of alarm:

5.1 General

The regulations, guidelines and provisions set out in Chapter 4.1 apply. The following must be considered when the TITANUS MICRO·SENS

aspirating smoke detector is being installed:

1. Interventions, changes and modifications to equipment are to be

avoided. If adjustments are unavoidable, they must be discussed with the operator, the manufacturer and/or the supplier (written approval).

2. All interventions to the in-house network (230 V/400 V supply) and to

outside systems must be carried out on the customer side. These include, for example:

• the power supply primary connection

• any connecting to outside systems (e.g. central units)

• the carrying out of any lightning and surge protection measures

which are required to comply with standards

5.5 Incorporating the reset board

The reset board can be used as an option for the TITANUS

MICRO·SENS

. The reset board is mounted in an additional housing. If several TITANUS MICRO·SENS the reset board is only connected into the detection line after the last TITANUS MICRO·SENS as per the switching plan (see Fig. 5.10).

The reset board can only be used if the idling current on the detection line is between 5 mA and 50 mA and the detection line terminal has an ohmic resistance. The reset impulse is triggered if the line voltage falls below 3V when the central unit is reset.

INSTRUCTION

The formulae shown for calculating the terminating resistor and the idling current on the detection line take account of the ideal status for signal evaluation.

If no acknowledgement is given from calculating the reset board terminating resistor, the value of the terminating resistor must be reduced by about 20 %.

Terminating resistor The reset board balances the detection line terminating resistor. It is

calculated afresh and incorporated in the reset board (Connection X1, see Fig. 5.10). The value of the terminating resistor R
