The unique ROOM·IDENT technology makes it possible to determine the lo-

cation of a fire when monitoring up to 5 separate areas. So that the emer-

gency 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.

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

systems guarantees homogeneous reaction behavior

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.

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 imme-

diately after it is inserted in the device base.

For maximum safety, the TITANUS

MICRO·SENS

can be fitted with redun-

dancy ventilators as an option. During operation of the device with the re-

dundancy ventilator, ROOM•IDENT is not possible.

Fitted with a network card, several TITANUS

devices can be

linked together in an Ethernet network. From a central point the user can, for

example, via Visu

Potential free contacts

Diagnostics

Designing detection points

The TITANUS

MICRO·SENS

has one potential free contact each for alarm

and fault So the smoke detection system can be switched to collective and

addressable (Via the address module of the particular FAS) recording lines

of any central fire alarm systems (FAS). A relay card (optional) can be con-

nected to the TITANUS

MICRO·SENS

in order to connect the potential-free

contact for the pre-alarm to a detector line of a CFDU.

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

sioning, 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.

The monitoring surfaces of the detection point type for the TITANUS

CRO·SENS

are to be set to match the point-specific smoke alarms. The de-

MI-

tection points can thus be designed similar to point-specific smoke alarms in

accordance with the particular national regulations.

Areas of Application

The TITANUS

air sampling smoke detection system is a fire

alarm system for the protection of rooms, equipment and air conditioning

Principle

ducts.

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 in-

spect 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.

Room protection

Product Description

The TITANUS

MICRO·SENS

is suitable, for example, for monitoring rooms

such as, e.g.

▪ double floors, intermediate ceilings,

▪ tunnels, ducts, cavities not easily accessible,

▪ warehouses, deep freeze stores, lift shafts,

▪ museums, cultural establishments,

▪ hotel rooms, hospital rooms, offices, prison cells, railway compartments.

▪ in server rooms with air conditioning,

▪ in ventilation ducts,

▪ in double floors, intermediate ceilings,

▪ in IT rooms, E-distribution rooms, transformer cells,

▪ for air conditioning cabinets (see Fig. 1.2),

▪ at bypass of air conditioning ducts.

Figure 2: Monitoring options for a circulating air conditioning cabinet or an air condi-

tioning duct (principle representation).

The TITANUS® aspirating smoke detection system can also be used for ear-

liest detection of fires in rooms with special air conditioning.

Its high level of sensitivity means goods and equipment can be reliably moni-

tored. The TITANUS

is therefore especially suitable for areas of application,

▪ in which because of concentrated high values early intervention is nec-

essary.

▪ in which equipment must always be operational.

▪ in which highly sensitive detection is required (e.g. in areas where, be-

cause of built-in filter elements, there is a low level of smoke particles in

the air).

▪ in which there are high rates of air change.

System Description

The TITANUS

MICRO·SENS

aspirating smoke detection system comprises

a detection unit, device base and pipe system.

The most important components of the TITANUS

MICRO·SENS

are the

sensitive detection unit for picking up smoke aerosols and the aspiration unit

with integrated air flow sensor for transporting air samples and for monitoring

the pipe system for breaks and blockages.

The pipe system consists essentially of pipe and fittings, in either PVC or

ABS plastics.

Figure 4: Air sampling smoke detection system TITANUS MICRO•SENS®

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.

3.1.1

Phase 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

unit and these are sent to the sensitive detection unit (see the following fig-

ure).

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 prin-

ciple incorporates four phases:

During operating conditions air samples are taken from the pipes covering

the various rooms. The samples are taken via fan to the detector unit and

analysed for possible smoke particles.

aspiration

Phase 2

Figure 5: Phase 1 ROOM·IDENT standard operation

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 ad-

justable Action - Alarm threshold. The system will activate an alarm once the

localisation is completed.

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.

Figure 7: Phase 3 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.

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 obscura-

tion), the TITANUS

MICRO·SENS

triggers the main alarm once the corre-

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

irflow monitoring

An airflow sensor checks the connected pipe system for breaks and block-

ages.

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 pres-

sure-dependent.

At the end of the adjustable delay time, the fault is shown on the smoke de-

tection 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 the fol-

lowing figure.

Figure 9: Example signal pattern in the airflow sensor during faults

Device monitoring

irflow adjustment

The detection unit is monitored for dirt and signal fault. Any fault which oc-

curs is displayed at the TITANUS

MICRO·SENS

and can be forwarded to

the FAS via a contact.

Airflow adjustment on the TITANUS

MICRO·SENS

is fully automatic when

the detection unit is inserted in the device base, if previously the Jumper X4

had been changed. This plug & play reduces the time needed for commis-

sioning to a minimum. It is also possible, however, to adjust the airflow using

the DIAG 3 diagnosis tool. This means the initialisation phase can be carried

out in an air pressure-dependent or air pressure-independent manner.

Resetting through FAS

A fault message is reset via the connected FAS. If whilst the TITANUS

CRO·SENS

is operating an FAS alarm and fault [messages] have to be re-

MI-

set at the same time as the control line, then as an option a reset board can

be inserted in a separate housing. The reset board can only be placed in a

separate housing and if the idle current on the line is between 5 mA and 50

mA. The line must be switched to dead for resetting. The effect is that when

there is any short-term switching off of the line voltage, the alarm and fault

messages on the TITANUS

06/13

MICRO·SENS

are automatically reset.

Diagnostics tool

Figure 17: Diagnostics tool for inputting and reading off device data

Using the DIAG 3 diagnosis tool, the device configuration for the TITANUS

can be changed during commissioning. For maintenance and servicing,

there is the option with the diagnosis software to display the stored and cur-

rent device status and error messages from the TITANUS

on a PC or lap-

top. For the data transfer to the diagnostics equipment the infrared interface

of the TITANUS

is used. There is a USB cable for transferring data from the

diagnostics equipment to the PC/laptop connection.

TIP

It is recommended that the commissioning statuses are read out, checked

and recorded.

Diagnosis messages can be deleted at any time using the DIAG 3 diagnosis

tool. If they are not deleted, the messages are stored in the TITANUS

for 72

hours. This allows for evaluation of short, sporadic faults (e.g. in changed

operating conditions).

available as to the risk management.

The status information and log data stored in network cards on all TITANUS®

air sampling smoke detection systems can be accessed via the SNMP pro-

tocol. By installing SNMP management software, customers can constantly

visualise and monitor the TITANUS

air sampling smoke detection systems.

When an incident occurs (e.g. a threshold is exceeded), an alert or a fault

message is sent to a managing entity or directly to another network partici-

pant via SNMP-Traps.

The integrated data logger is used to record event data (alerts and faults)

and log data (smoke level, air flow, air flow temperature, detection status,

temperature sensors) from TITANUS

air sampling smoke detection system.

The event and log data are saved on a memory card at pre-defined logging

Aspiration apertures for room monitoring

Aspiration reduction films

Figure 24: Aspiration aperture with aspiration reduction film and banderol

An air sampling point is a 10 mm-hole in the air sampling pipe covered with a

patented aspiration-reducing film sheet with the appropriate opening diame-

ter. The size of the opening depends on the pipe design (see chapter De-

sign, “Pipe Design”).

To prevent the film sheet from coming loose, it is fixed with transparent

marking tape with red edges and a 10 mm-hole. The marking tape is fixed to

the film sheet in such a way that the air sampling point is not covered and

remains visible even at a distance.

The standard type AF-x aspiration reduction films and the type AF- bande-

rol’s are not suitable for use in very low temperature areas.

Aspiration reduction clips are to be used in these areas instead.

Aspiration reduction clips

Figure 25: Air flow reducer for dirty areas and deep freeze storage

The air sampling points, when used in areas where blockages can occur, are

equipped with a patented plastic clip, type AK-C, and a patented flexible air

flow reducer, type AK-x.

When used in deep freeze areas, the flexible air flow reducer near the air

sampling points expands and the ice is blasted off during blow-through. The

special plastic clip ensures that the air flow reducer remains in place.

For designs in areas requiring a blow-through system (e.g. dusty), air flow

reducers with plastic clips are used rather than aspiration-reducing film

sheets with marking tapes, because the openings can be blown clear more

easily. The plastic clips are more resistant at high pressures and can be

cleaned more effectively due to the rubber core.

If a hidden installation is required for monitoring of the pipe system, it can be

installed in the ceiling void. The ceiling feed through are put in the false ceil-

ing. According to the pipe design guidelines the ceiling feed-through are

equipped with aspiration-reducing film sheets with defined air sampling

points (see chapter Design "Pipe Design") and are connected to the pipe

system with air sampling hoses.

If the maximum length of these hoses is 1 m, refer to the pipe design de-

scribed in chapter "Design". If - due to construction - hose lengths of more

than 1 m are required, the air sampling pipe system must be calculated

separately (calculation is made by WAGNER).

The ceiling feed through is applicable for false ceiling panels with a thickness

of up to approximately 35 mm. The aspiration-reducing film sheets are avail-

able in two colours (pure white, RAL 9010 and papyrus white, RAL 9018)

back the dust particles in a heavily polluted atmosphere using the filter me-

dium. 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 be-

EN 54-20 or ISO 7240-20

The air sampling smoke detection systems shall be planned in accordance

with the project planning guidelines described in Chapter 5.2.1 in order to be

compliant with EN 54-20 or ISO 7240-20.

The following guidelines must also be complied with for systems in accor-

dance with the requirements of VdS Schadenverhütung:

▪ "Guideline for automatic fire alarm systems, planning and installation",

VdS Schadenverhütung GmbH, Cologne, Germany (VdS 2095)

▪ "Local application protection for electric and electronic equipment rules

for planning and installation" guideline, VdS Schadenverhütung GmbH,

Cologne, Germany (VdS 2304)

▪ The technical bulletin “Project Planning for air sampling fire alarms” VdS

Schadenverhütung GmbH, Cologne, Germany (VdS 3435)

The following national regulations must also be complied with in Germany,

for instance:

▪ DIN VDE 0833 part 1 and 2 "Alarm systems for fire, intrusion und hold-

up"

▪ Additional regulations for installing fire alarm systems which are laid

down by fire authorities and building supervisory boards or building regu-

5.1.2

lation authorities and are only valid locally.

Pipe systems

When planning the pipe system, it must be ensured that reliable fire detec-

tion is guaranteed for any fire present in an installation or in a monitored

area.

The number of the intake apertures and the pipe system design depends on

the size, ventilation and shape of the monitored area. The aspiration aper-

tures 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:

06/13

TITANUS

MICRO·SENS

Symmetry of the pipe system

Design

To insure equal air intake for all aspiration holes the following rules must be

obeyed:

▪ The length of the shortest and longest branch must not exceed a ratio of

1:2.

▪ The number of aspiration holes of the corresponding branches must not

exceed a ratio of 1:2.

▪ The aspiration holes should be evenly distributed on the corresponding

branches.

NOTICE

Each connected pipe system must comply with the design limits of TITA-

NUS

for the selected pipe design (please refer to chapter “Project Plan-

ning Limits”):

20 and need not be considered further.

If the pipe system includes 90 ° angles, the maximum overall length of the

pipe system will be reduced. In this case, a 90 °-angle corresponds to a

straight pipe length of about 1.5 m air sampling pipe.

NOTICE

Bends are to be preferred over angles. An excessive number of changes in

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

sure that the current intake increases.

Air flow monitoring

EN 54-20 or ISO 7240-20 requires the recognition of a 20 percent change in

the air flow volume by the detector module’s air flow sensor system. The ac-

tivating 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 pressure-

dependent air flow compensation for both of these settings.

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

20 or ISO 7240-20 conformity.

Project planning for the air flow monitoring system in sampling pipes is car-

ried out while taking into consideration the respective national regulations for

djusting the

air flow sensitivit

each country.

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

tion. Breakage and stoppages must be detected reliability with low suscepti-

bility to malfunction.

The activating threshold and for this reason the sensitivity of the air flow

sensor is continuously adjustable from 10 – 50 %.

Limitations

It is recommended to always select the greatest possible level which is

permissible according to national standards.

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 fol-

lowing modifications have to be regarded.

The air flow monitoring may only be set, if:

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

carried out “(see Chap. 5.3.1 “Pipe project planning individual aperture

monitoring“),

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

sure (see Chap. 8.1.2 “Air pressure dependent air flow compensation“)

und

▪ No large air flow fluctuations occur.

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

NOTICE

If the air sampling smoke detection system and pipe system are in areas

with different air pressure, the air sampled by the TITANUS

tion”).

not allowed with ROOM·IDENT these applications cannot be served.

Sensitivity

According to EN 54-20 or ISO 7240-20, 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 de-

termined for each classification according to Chapter 5.2.

Air sampling smoke detection systems with a higher sensitivity class accord-

ing to EN 54-20 or ISO 7240-20 also meet the requirements of the lower

classes.

Project planning

Project planning guidelines

In order to conduct project planning in accordance with the EN 54-20 or ISO

7240-20 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

5.2.1.1

project planning tables in the appendix.

Determining the necessary accessories

Since the accessory components, such as filters, have a certain influence on

the dimension of the pipe planning, the suitable accessories must be se-

lected 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.

NOTICE

Components which have not been approved by WAGNER are used, CE

conformity on the basis of EN 54-20 or ISO 7240-20 will not be possible.

The following accessory components should be taken into consideration in

the process:

▪ Air filters

▪ Steam trap

▪ VSK stop valves

▪ Detector box

Location of the pipe system

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

the area v

to v3.

To achieve the best location for constructing the pipe system, the exhaust

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.

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

observed:

▪ As the TITANUS

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.

The pipe is concluded with an end cap without a bore.

The aspiration apertures should be arranged against the air flow.

During project planning, it is to be taken into account that the air conditioning

ducts for mounting the pipe system are often only accessible from two sides.

Project design with air sampling hose

The application of an air sampling hose can be useful if several direction

changes on a short distance of a pipe system is required, e. g. for avoiding

any obstacles.

As the transport time can be manipulated negatively by application of an air

sampling hose, the influence of the used air sampling hose is to be deter-

mined on the allowed total length of pipe as follows.

Consideration during application of air sampling hose:

For calculation the maximum length of air sampling pipe with air sampling

hose, the length of the air sampling hose must be multiplied by the certain

factor b and deducted from the allowed total length of pipe.

Air sampling pipe length = Total pipe length – (Length of the air sampling hose * Factor b)

Factor for calculation of the air sampling hoses length:

Air sampling hose Factor b

Type SCH-PG16 1,1

Type SCH-P25 0,5

Example 1: Altogether, the air sampling hose of type SCH-PG16 with a

length of 12 m shall be connected to a TITANUS

air sampling smoke de-

vice. The allowed total length of pipe is 50 m. The result for the maximum air

sampling pipe inclusive air sampling hose is:

Air sampling pipe length = 50 m - (12 m * 1,1) = 36,8 m

Example 2: In case of a pipe project planning, 45 m of air sampling pipe and

air sampling hose shall be connected to a TITANUS

air sampling smoke

device. In accordance to the project planning scale, the allowed total length

of pipe can be 50 m for the complete pipe project planning. The result for the

maximum length of the complete air sampling hose of type SCH-P25, which

can be integrated within the pipe project planning, after formula adjustment

is:

Length of the air sampling hose = (Total pipe length - Air sampling pipe lenght) / Factor

Length of the air sampling hose = (50 - 45 m) / 0,5 = 10 m

Project planning with air return

In some cases, in which differences of air pressure between the area of air

sampling device and the area of air sampling point exist, a channel of air

pressure of the aspirated test air in the pressure area of air sampling points

can be necessary. Therefore, an air sampling hose with a right length should

be connected on the air outlet of the air sampling device.

As the transport time of an air sampling smoke detection device can be ma-

nipulated negatively by an air return, the influence of the air return to the al-

lowed total length of pipe is to be respected.

An air return with a pipe with Ø 40 mm has no influence and can be pro-

jected and/or retrofitted without reducing the total pipe length and / or retrofit-

ted.

Consideration of air returns:

For calculation the maximum length of air sampling pipe, the length of the air

return must be multiplied by the certain factor a and deducted from the al-

lowed total length of pipe.

Air sampling pipe lenght = Total pipe length – (Length of the air return * Factor a)

Factors to calculate the lengths of air return (∅ 25 mm):

Length of the air return Factor a

0 bis 5 m 0,0

> 5 bis 10 m 1,6

> 10 bis 25 m 3,2

NUS

. The allowed total length of pipe is 50 m. The result for the maximum

air sampling pipe is:

Air sampling pipe lenght = 50 m – (10 m * 1,6) = 48,4 m

Power supply

The alarm-ready status in the fire protection system and the aperture of an

alarm are taken into account when rating the external mains supply. In the

system's alarm-ready status, the mains supply must supply standby current

to the air sampling smoke detection systems and ensure that the emergency

power batteries are charging in accordance with DIN VDE 0833 Part 1 (80%

load in 24 hours).

The mains supply of the air sampling smoke detection systems shall be

approved according to EN 54-4.
