1.1 Purpose

The ASD 532 aspirating smoke detector has the task of continuously taking air samples via a sampling pipe tube network from a monitored area and feeding the samples to a smoke sensor. Thanks to this detection method and the product’s excellent properties under severe ambient conditions, the ASD 532 aspirating smoke detector is used wherever problems are to be expected owing to poorly accessible monitored areas or latent disturbance variables during operation such that optimal protection can no longer be guaranteed with conventional point detectors.

The SSD 532 smoke sensor is used in the ASD 532. It is available in the three following versions and sensitivity ranges:

• SSD 532-1 Alarm sensitivity range 0.5%/m to 10%/m

• SSD 532-2 Alarm sensitivity range 0.1 %/m to 10%/m

• SSD 532-3 Alarm sensitivity range 0.02%/m to 10%/m.

The ASD 532 aspirating smoke detector has two slots for additional modules. The following modules can be fitted:

• XLM 35 eXtended Line Module

• RIM 36 Relay Interface Module with 5 relays;

• SIM 35 Serial Interface Module.

With the installation of a eXtended Line Module XLM 35 the ASD 53 2 aspirating smoke detector can be ideally connected to the fire alarm systems SecuriFire (SecuriLine eXtended) and Integral (X-Line) via the addressable loop. Control operations and changes to the ASD device configuration can be carried out directly from the FACP (in preparation). For this purpose the FACP user software “SecuriFire Studio” and “Integral Application Center” are used to start the “ASD Config” configuration software for access to the ASDs; the configuration software is then used to make changes to the ASD 532.

A further installation option is the RIM 36 relay interface module. This module enables the availability of all three pre-signal levels as well as the states “smoke sensor dirty” and “LS-Ü pipe blockage” as relay contacts. The relays are also freely programmable via the “ASD Config” configuration software.

The SIM 35 Serial Interface Module is for networking multiple ASD 532 aspirating smoke detectors via RS485 bus. Using the “ASD Config” configuration software, all ASD 532 units present in the network can be visualised and operated from a PC. The master module in the ASD network is the SMM 535, by means of which a PC is connected.

1.2 Uses and applications

Thanks to the detection method, air sampling by means of a sampling pipe tube network and the good properties of the product under extreme ambient conditions, the ASD 532 aspirating smoke detector is used wherever problems can be expected owing to poorly accessible areas to be monitored or latent disturbance variables during operation such that optimal protection cannot be guaranteed with conventional point detectors. This includes:

• Space surveillance:

EDP rooms, ultra-clean rooms, warehouses, hollow floors, protection of cultural assets, transformer stations, prison cells, etc.

• Equipment monitoring:

EDP systems, electrical distributors, switch cab inet s, etc.

The ASD 532 can also be deployed in areas where normally conventional point detectors are used. Local regulations and provisions must be observed from case to case.

The response behaviour of the ASD 532 has been tested in compliance w ith EN 54-20, Class A, B and C. When control-unit-specific alarm transmitters, line monitoring elements etc. are used, the ASD 532 can be connected via its

potential-free change-over contacts to all common fire alarm systems virtually without restrictions.

2.1 General operating principle

In the sampling pipe tube network, the fan generates a vacuum which results in fresh air continuously reaching the detector housing via the sampling pipes. In this way the smoke sensor is constantly supplied with new air samples from the monitored area. Should the smoke concentration exceed the permissible value, the ASD 532 triggers an alarm. The alarm is indicated visually on the ASD 532 and can be transmitted via a potential-free change-over contact to a superordinate fire alarm control panel.

The operational reliability of the aspirating smoke detector depends on the functional reliability of the smoke sensors and on the constant air supply to the system. A fan failure, blockage of the sampling holes or pipe breakage must be communicated to the fire alarm control panel in the form of a fault signal. This condition is satisfied by the airflow monitoring of the ASD 532.

2.2.1 Power supply

The operating voltage of the ASD 532 is +14 to +30 VDC. On the AMB 32 Main Board, 5 VDC of the operating voltage is diverted for internal voltage use.

The operating voltage is monitored on the AMB 32 for undervoltage. If the operating voltage falls below 13 VDC (+0 / –0.3 VDC), the ASD 532 triggers an undervoltage fault.

2.2.2 Fan control

The physical and electrical properties of a fan cause a brief power surge when it is switched on and starts up, which in turn affects the conductor dimensioning and the total power consumption of the fire alarm system.

A specially designed circuit therefore ensures that the fan cannot exceed a specific maximum power consumption in its startup phase. When the ASD 532 is switched on, the computer-controlled fan speed starts up slowly. After the fan has been powered up, the speed is kept constant.

Any blocking of the fan is detected by evaluating the motor speed. If the specified threshold is undershot, the fan supply is switched off and a fault is signalled.

Depending on the size of the system and/or environment, the fan can be operated at different speeds (by means of the “ASD Config” configuration software). This is useful primarily in critical areas (long pipes) to increase the transport speed in the sampling pipe tube network (high speed) or to reduce the noise level in cases where the noise level produced by the fan is a disturbance (low speed). The following fan speed levels can be selected:

Level

Notice

The fan speed levels can be changed only with the “ASD Config” configuration software. For applications and commissioning without “ASD Config” configuration software, Level II must always set. If the fan speed is changed (by using the “ASD PipeFlow” permissible transport time according to EN 54-20 is not exceeded. After the fan speed has been changed, it is imperative

2.2.3 Microcontroller

The entire program and switching sequence is controlled by a microcontroller. The firmware is stored on a Flash PROM. System-specific configurations are stored in an EEPROM.

The program is monitored by the internal watchdog of the microcontroller. In the event of a failure of the microcontroller circuit, an emergency fault is triggered. This is signalled on the device by the steady lit Fault LED. The “Fault” relay switches.

2.2.4 Programming / operation

The operation of the ASD 532 aspirating smoke detector in normal mode (after commissioning) is limited to switching on/off or to resetting a triggered event (alarm/fault). Operation is generally via the FACP, with input of the “Zone On/Off” and “Reset” functions (on “Reset external” input of the ASD 532).

Events triggered on the ASD 532 can be reset locally using the “Reset” key on the control unit or by briefly actuating the “Reset External” input. The reset is possible only if the triggered event is no longer pending (e.g. smoke sensor no longer has smoke). The application of a continuous signal at the “Reset external” input also deactivates (switches off) the ASD 532 (see also Sec. 2.2.8 and 6.6.2).

Notice

To aid commissioning the ASD 532, there are two 7-segment displays, an alphanumeric display, and two keys (“UP” and “OK”) inside the device on the AMB 32 Main Board. These elements provide a type of rotary switch function, i.e. displays and positions in the range A00 to Z99 may appear.

These elements are used when commissioning the ASD 532. Device settings for predefined system limits can also be called up – EasyConfig. These pre-defined positions are stored with normative values for response sensitivity, airflow monitoring (LS-Ü) and pipe configuration. They also contain positions which allow deviations from the normative limits with regard to airflow monitoring. The EasyConfig process allows the device to be commissioned without the ASD Config software. If system- specific programming has to be carried out (e.g. after a calculation with “ASD PipeFlow” or when programming RIM 36), the “ASD Config” configuration software must be used.

2.2.7 Outputs

There are two OC outputs (OC Flt and OC Al) on the ASD 532. Parallel indicators, feedback indicators or other consumers (relays) can be connected to these outputs. The outputs are configured with the following criteria (see also Sec. 6.6.5):

AMB 32

2.2.8 Inputs

The ASD 532 has an “External reset” input used to reset the device to its normal state after an event. The input is potentialfree (opto-isolator). It can be actuated both on the “plus” and on the “minus” side. The input operates in the 5 to 30 VDC range and has a pulse bandwidth of 0.5 to 10 sec. When a continuous signal is applied for longer than 20 s, the ASD 532 is deactivated (fault state) (see also Sec. 6.6.2). Switching inactive via the “Reset external” input works only if the ASD 532 is not equipped with an XLM 35.

The “OEM” input is for actuating alarms and faults from third-party detectors. The input is potential-free (opto-isolator ) and can be actuated “plus” side or “minus” side in the range of 5 to 30 VDC. By default the input is not enabled and must be parameterised using the “ASD Config” configuration software (OEM input signal). It actuates the alarm and fault states on the ASD (relay + LED). The same delay times and latching states as for triggering from the SSD 532 apply.

Warning

In some cases actuations via the OEM input may not comply with requirements in accordance with EN 5420 and may therefore only be used after consulting with the manufacturer.

2.2.9 Interfaces

Depending on the installed additional modules, the ASD 532 has the following interfaces:

2.2.10 Airflow monitoring

Airflow monitoring is based on the calorimetric measuring method (mass flow rate measuring method). An airflow sensor is installed in the detector housing in such a way that any change in the sampling pipe (pipe breakage, pipe

blockage) can be evaluated. If there is an initial reset of the device and the sampling pipe is intact, the data of the airflow measurement is registered and

saved as reference values (100%). The system sets the values in the middle of an electronically formed monitoring window. In the event of a shift in the values (actual values) out of the monitoring window (±xx%) owing to pipe blockage or pipe breakage in the sampling pipe, the ASD 532 triggers an “airflow fault”. The monitoring window can be set to different sizes on the ASD 532.

A variable delay time ensures that disturbance variables, e.g. air turbulence, are ignored. To handle fluctuations in the ambient temperature, the ASD 532 is equipp ed with a temper at ure co mpen sation circuit.

ASD 532

According to EN 54-20 a change in the airflow that is greater than ±20% must be reported as a fault. After the initial reset the airflow is displayed as 100% in the ASD 532 aspirating smoke detector when the sampling pipe is correct and clean. In the switch positions A11 to C31 any change in this value greater than ±20% – i.e. below 80% (dirt/pipe blockage) or above 120% (pipe breakage) – triggers an “airflow fault” after the LS-Ü delay time of 300 s has expired.

W01 to W44 are stored with airflow monitoring values which are

2.2.11 Smoke sensor monitoring

The smoke sensor used on the ASD 532 is monitored on the AMB 32 Main Board. A failure of the sensor electronics, a dusty or dirty smoke sensor is registered as an event code and displayed as a state or fault. Likewise, the connection line between the smoke sensor and the AMB 32 is monitored and a fault is signalled if there is a failure. To avoid false alarms, the SSD 532 smoke sensors used in the ASD 532 have a technical measure (TM) for comparing fire parameter pattern matching (measure for verifying the alarm state according to DIN VDE 0833-2).

ASD532 Operating Manual

Function

Warning

The cascading function may not comply with sulting with the manufacturer.

2.2.12 Alarm release

The smoke sensor cyclically transmits its state as well as the signal amplitude / smoke level to the AMB 32 main board. The state of the smoke sensor is processed further on the AMB 32. If the set threshold values (alarm, pre-signal 1–3) are exceeded, the corresponding state “Alarm”, “Pre-signal 1–3” is triggered on the ASD 532.

2.2.12.1 Alarm 2

The “ASD Config” configuration software offers the possibility of also enabling an “Alarm 2” for the ASD 532. W he n a ct i va ted, that alarm is always above exceeded, no additional display is actuated on the ASD 532. Alarm 2 can also be programmed on a RIM relay. Alarm 2 is always a follow-up alarm to the EN 54-20 alarm and is therefore not subject to the response requirements of EN 54-20. The setting options for alarm 2 using the “ASD Config” configuration software can be found in Sec. 7.2.1 (Table A).

2.2.12.2 Alarm cascading

The “ASD Config” configuration software offers the possibility of activating a cascading scenario for the alarm release. This means that the activated pre-signals 1 to 3 and the alarm are triggered one after the other according to the set delay times (pre-signal delay and alarm delay).

2.2.12.3 Isolating the smoke sensor

This function is used to place the ASD 532 in an isolated state using the “ASD Config” configuration software. This means that test alarms can then be triggered on the ASD 532 without activating superordinate systems (FACP) (relays, OC outputs, XLM do not trigger). When the “Isolate” function is switched on, a fault is triggered on the ASD and forwarded to the superordinate centre. On the ASD the “Fault” LED is then continuously lit.

2.2.13 Autolearning

With the Autolearning func tion the ASD 532 is able to monitor the ambient air over a defined period of time (adjustable from one minute to 14 days) via the sampling pipe and send the results to the system; based on that it can then determine the ideal trigger threshold of the smoke sensors. This prevents operational disturbance variables such as dust, vapour and smoke from triggering false alarms on the ASD 532. It means it is also possible to set a highly sensitive trigger threshold (far below the trigger threshold requirements of EN 54-20), for example for clean rooms. During Autolearning the biggest amplitude of the smoke sensors is determined and then multiplied by an adjustable factor of 1.1 to 10 to define the final trigger threshold. The finally determined trigger threshold, however, can never be less than the minimum possible trigger threshold (depending on the smoke sensor type, see example 2) and not greater than the trigger threshold for fulfilling the EN 54-20 requirement ( see example 3). If the day/night control is activated, the values for both time periods are determined separately.

Example 1:

• Smoke sensor type = SSD 532-2 (0.1–10%/m)

• Required trigger threshold as per system limit and “ASD PipeFlow” for EN 54-20, Class C = 0.4 %/m

• Selected Autolearning factor = 2

• Maximum amplitude (smoke level) during Autolearning = 31%/m

Calculation: 0.31 x 2 x 0.4 %/m = 0.248 %/m Result: Trigger threshold of the smoke sensor = 0.248%/m

Example 2:

• Smoke sensor type = SSD 532-3 (0.02–10%/m)

• Required trigger threshold as per system limit and “ASD PipeFlow” for EN 54-20, Class A = 0.03%/m

• Selected Autolearning factor = 1.1

• Maximum amplitude (smoke level) during Autolearning = 50 %/m

Calculation: 0.5 x 1.1 x 0.03 %/m = 0.0165 %/m Result: Trigger threshold of the smoke sensor = 0.02%/m (minimum possible trigger threshold of the SSD 532-3)

Example 3:

• Smoke sensor type = SSD 532-2 (0.1–10%/m)

• Required trigger threshold as per system limit and “ASD PipeFlow” for EN 54-20, Class C = 0.2%/m

• Selected Autolearning factor = 10

• Maximum amplitude (smoke level) during Autolearning = 16%/m

Calculation: 0.16 x 10 x 0.2%/m = 0.32%/m Result: Trigger threshold of the smoke sensor remains at 0.2%/m and thereby fulfils the EN 54-20 Class C requirement.

2.2.16 Event memory

The ASD 532 has an event memory capable of storing up to 1,000 events. The latest (i.e. most recent) event is always placed in the first position. If the memory exceeds 1,000 events, the oldest event is deleted. The event memory as a whole can be deleted only by the manufacturer. The event memory can be read out directly on the ASD 532 using the rotary switch function (switch position E = last 99 events, see Sec. 8.5.3) or using the “ASD Config” configuration software (up to 1,000 events can be selected).

2.2.17 Data logging on the SD memory card

Measurement values: All relevant measurement values are written to the SD memory card every second (default, can be

changed with ASD Config) for each sensing tube and saved in Log-Files (*.xls file). After 28,800 entries (corresponding to 8 hours with an SD memory card interval of 1 s), a new Log-File is automatically generated. A total of 251 Log-Files (L000.xls to L250.xls) can be generated for long-term logging. After the last Log-File the oldest one (L000.xls) is overwritten. The 251 Log-

Files are sufficient to cover 83 days of data logging (with SD memory card interval of 1 s). The Log-Files can be opened in Ex-

cel and the data processed with the diagram assistant to create charts. Events: All events which occur in the ASD 532 are written to the Event-Files (*.aev file). After 64,000 events a new Event-File is created automatically. A total of 10 Event-Files (E000.aev to E009.aev) can be generated for long-term logging. After the last Event-File the oldest one (E000.aev) is overwritten. The 10 Event-Files are sufficient to log over 640,000 events. The

2.2.18 Reset types

All events triggered on the ASD 532 go int o self-holding mode whenever the default configurations are used. To reset, carry out a state reset.

The following reset types are possible (see Sec. 2.2.18.1 to 2.2.18.3).

2.2.18.1 State reset

A state reset is triggered by pressing the “Reset” key on the control unit or by actuating the “Reset external” input (see also Sec. 6.6.2). The state reset can be triggered only after an event, and only if the criterion that resulted in the event trigger is back in the normal state (e.g. smoke level in the smoke sensor is again below the trigger threshold or a fault event is rectified). As a result of the state reset, the ASD 532 continues to run “normally” and the fan does not stop.

2.2.18.2 Hardware reset

A hardware reset is triggered if there is a brief interruption in the supply voltage or if the “HW res et ” key is briefly pressed on the AMB 32 (see also Fig. 40 and Fig. 45). This restarts the ASD 532. The fan stops and then slowly starts up again (start-up control). The previously programmed parameters of the ASD 532 are retained (system-specific configurations ).

2.2.18.3 Initial reset

An initial reset is triggered according to the information in Sec. 7.3.5. An initial reset determines the basic data (e.g. connected sampling pipe, airflow data), which is then saved on the ASD 532.

The airflow monitoring is also automatically adjusted. The basic data remains stored until such time as another initial reset is carried out. An initial reset does not discard the previously defined installation-specific parameters (system limits, response grade).

During commissioning speed, it is imperative work on the ASD 532 (replacement of airflow sensor, aspirating fan unit, AMB 32 main board). After an FW upgrade, an initial reset is required only if expressly mentioned in the relevant firmware description. When carrying out an initial reset, make sure the sampling pipe has been correctly implemented (sealed connecting points, sampling holes correctly dr ill ed).

3.1 Mechanical

The ASD 532 aspirating smoke detector consists of the detector housing and a sampling pipe tube network. The sampling pipe is made of hard PVC or ABS tubes with an external diameter of 25 mm and an internal diameter of 20 mm (see also Sec. 5.3). In special applications – e.g. in extremely corrosive environments – other tube materials can also be used, subject to the specifications set out in Sec. 5.3. The sampling pipe has several sampling holes whose size is such that each hole extracts the same amount of air. The sampling pipe may be I-, U-, T-, H-, or E-shaped. The sampling pipe is symmetrical ly designed in principle. Asymmetrical sampling pipe tube networks can also be implemented with the help of the “ASD PipeFlow” calculation software.

The housing cover on the detector housing is opened by means of four rotary snap locks. Integrated in the detector housing is a fan which, in conjunction with the sampling pipe, ensures an uninterrupted supply of air

to the detector housing. Airflow monitoring detects any pipe blockages and pipe breakages in the sampling pipe. There is one chamber for the smoke sensor in the detector housing. The air channel through the smoke sensor and fan are

separated from the other parts inside the detector housing; this means the ASD 532 is able to remain fully operational during commissioning and maintenance work even when the housing cover is open.

The AMB 32 Main Board contains the processor-controlled evaluation electronics and the connection technology. There are two slots in the detector housing for installing optional additional modules (XLM 35, RIM 36, SIM 35).

Pre-defined labelling strips are used for labelling the control unit in the housing cover. If the device is mounted in a position rotated by 180°, the labelling strip can be turned accordin gly .

Smoke sensors of the following type can be fitted in the ASD 532 (see also Sec. 4.9 and 6.6.4):

• SSD 532-1 Alarm sensitivity range 0.5%/m to 10%/m

• SSD 532-2 Alarm sensitivity range 0.1 %/m to 10%/m

• SSD 532-3 Alarm sensitivity range 0.02 %/m to 10%/m

4.2.1 System limits

The use of an ASD 532 aspirating smoke detector is subject to the system limits listed below and compliance with EN 54-20 requirements. Depending on the planning process, the system limits as set out in Sec. 4.4 and 4.5 also apply.

4.3 Planning aids

4.3.1 Planning with “ASD PipeFlow” calculation

The “ASD Pipe Flow” c alculation software is used for planning the sampling pipe tube network. Its purpose is to design on a drawing the pipe layouts required for implementing a system and assign the sampling holes. The “ASD PipeFlow” calculation software provides a selection of different tube materials, fittings and accessory parts (filter-boxes, water retaining boxes, etc.). The end result of the calculation software specifies the parameters required for a norm-compliant trigger in accordance with EN 54-20, Class A to C, after which the parameters are programmed on the ASD 532. It is also necessary to select the smoke sensor type with the appropriate sensitivity range corresponding to the response sensitivity calculated by “ASD PipeFlow”.

Asymmetrical sampling pipe tube networks can also be planned and set up using the “ASD PipeFlow” calculation software. System limits for EN 54-20 compliant triggering are defined in the calculati on software.

The material stored in the “ASD PipeFlow” calculation software for the sampling pipe – and the “ASD PipeFlow” calculation software itself – are an integral part of the VdS device approval. A list of the available materials for the sampling pipe is provided in a separate document (T 131 194).

The number and arrangement of the ASD 532 units are based on the size of the space. In general the monitoring areas are the same as for point-type detectors. Guidelines that apply to specific objects – e.g. high-rack storage buildings – must be observed. The sampling pipe tube networks are to be laid out in such a way that any anticipated fire is detected in its initial stages. The aspirating smoke detectors should be positioned in such a way that false alarms are avoided. When planning without “ASD PipeFlow” symmetrically (including sampling holes). Any deviation in symmetry must not exceed ±10%.

An excessively h direction changes significantly affects detection time. When planning without “ASD PipeFlow” calculation, do not use more than a maximum of two 90° angles per sampling pipe.

4.4.3 Types of sampling pipe layouts for space s urveillance

Typical layout types for space surveillance are I-shaped, U-shaped, T-shaped, H-shaped and E-shaped sampling pipe tube networks. Other sampling pipe layout designs can also be planned using the “ASD PipeFlow” calculation software.

When planning with “ASD PipeFlow” calculation, irregularly spaced sampling holes are also possible (Fig. 7).

Fig. 7 Examples of planning with “ASD PipeFlow” calculation

If planning without “ASD PipeFlow” calculation, make sure the sampling pipe tube networks are set up symmetrically (max. symmetry deviation of ±10%). This applies to the tube layout and the spacing between the sampling holes (Fig. 8).

4.4.4 System limits for space surveillance without “ASD PipeFlow” calculation

The system limits specified in this section apply to planning without using the “ASD PipeFlow” calculation software. Stored under the system limits are switch positions with pre-defined values. There are two areas, with the following meaning:

• normative system limits according to EN 54-20, Class A to C, switch positions A11 to C31;

• Non-normative syste m limits, switch settin g s W01 to W44.

Fig. 9 below illustrates the possible sampling pipe tube networks with definitions of tube length specifications. The maximum tube lengths and number of sampling holes as well as the required smoke sensor types are found in the tables in Sec. 4.4.4.3 based on response class.

Fig. 9 Sampling pipe definitions

4.4.4.1 Normative system limits for space survei llan ce with out “ASD PipeFlow” calculation

Stored under switch positions A11 to C31 are values which are necessary in terms of alarm response sensitivity and airflow monitoring for compliance with EN 54-20 Class A to C. The switch position designation is deciphered as follows:

• First digit Response grade A, b, C (A = highly sensitive, b = sensitive, C = standard)

• Second digit System limit 1, 2, 3 (tube network length, number of sampling holes)

• Third digit Tube networks 1 (number of sampling pipe tube networks on the ASD 532, only 1 possible).

Example: b21 response grade b / system limit 2 / 1 sampling pipe tube network

4.4.4.2 Non-normative system limits for space surveillance without “ASD PipeFlow” calculation

Switch positions W01 to W44 contain system limits which fulfil only the alarm response sensitivity compliant with EN 54-20 Class A to C, but not

the normative limits with regard to airflow monitoring. As they are identical with the system limits A11 to C31 in terms of tube topology (tube network length, number of sampling holes), the switch positions W01 to W44 are also in- cluded in the tables 4.4.4.3 below. For more details about switch positions W01 to W44 with regard to airflow monitoring, please refer to Sec. 4.4.4.4.

4.4.4.5 Sampling holes for planning without “ASD PipeFlow” calculation

To ensure that all the sampling holes take in the same amount of air, the diameter of the sampling hole on the sampling tubes fitted must increase as the distance from the detector housing increases.

Fig. 10 Size of sampling holes

The tables below show the respective hole diameters for the numbers in Fig. 10 as a function of the number of sampling holes per sampling branch (this applies also to high-rack storage facilities).

If required, the sampling holes can be created using the special “sampling hole clips”. The sampling hole clips are available in various sizes (i.e. with hole diameters as indicated in the table above: 2.0 / 2.5 / 3.0 / 3.5 / 4.0 / 4.5 / 5 / 5.5 / 6 / 6.5 / 7 mm). See also Sec. 5.5.9.

are to be used. Laying the voltage supply line and line in parallel is permitted. A separate wire pair is to be used for the ASD 532 voltage supply. The electrical installation is usually performed with commercially available cables. Depending on the country of use, special

fire detector cable may be required by the relevant authorities. The relevant country-specific authorities should therefore be consulted concerning the required cable types.

The installation cable must have a minimum wire diameter of 0.8 mm (0.5 mm²). Please refer to Sec. 4.8.2 for determining

To ensure the ASD 532 is able to operate fault-free, the conductor cross-section must be rated so that the maximum required power consumption is available in all cases at the end of the electric installation (i.e. at the ASD 532).

When determining the conductor cross-section, the highest possible power consumption by the ASD 532 during normal operation (after switching on) is the decisive factor. Due to its circuitry design, the ASD 532 has t he highest power consumption at the minimum supply voltage, i.e. at 14 VDC.

5.4 Mounting the detector housing

Warning

Mounting work on the detector housing is best carried out without the smoke sensors fitted. The smoke sensor is always installed in the detector box just when the ASD 532 Sec. 6.3). Depending on the circumstances (e.g. long periods of time between mounting and commissioning or if the environment is extremely dusty (construction work), the housing cover should be

The detector housing should always be kept in the room to be monitored. If this is not possible, ensure that the detector housing is located in a room that has the same air pressure or – in the case of air-conditioned rooms – the same climate and pressure zone. In applications where the sampling pipe and detector housing are mounted in different climate zones, a return sampling pipe to the monitored area is required. The return line can be adapted after removing the air outlet pipe plug on the ASD 532 housing. See also under Sec. 4.6, 5.4.2 and 5.4.3. The maximum length for the return line must not exceed 20 m.

Special settings (larger airflow window, longer delay time etc.) may have to be made in areas with significant temperature fluctuations of more than 20°C at both the sampling pipe and on the detector housing. This also applies to temperature differences of more than 20°C between sampling pipe and detector housing.

An easily accessible installation location should be chosen so that the detector housing can be worked on without aids such as ladders and scaffolding. The ideal installation height for the detector housing is about 1.6 m above ground level (top edge of the detector housing).

On the entry side of the connection cable, a minimum distance of 10 cm to custom er -si de parts mu st be observ ed. When positioning the detector housing, take into account the fact that the noise caused by the fan may in some cases be per-

ceived as a disturbance. If no suitable location is available for the detector housing, it may be necessary to mount it in a sound insulated cabinet (e.g. ASD sound insulation housing). If air recirculation in the same climate zone as the sampling pipe is necessary, it can be implemented by means of a tube piece out of the acoustically insulated cabinet. The tube piece exiting from the sound insulated cabinet (transition) must be properly sealed. When using the ASD sound insulation housing, an M32 cable screw union is used for the transition. For further details about the ASD sound insulation housing contact the manufacturer.

5.4.2 Mounting positions for the detector housing

In principle the detector housing can be mounted in the X, Y or Z axis. However, because of the labelling for the indicator elements, it is advisable to mount the device in the Y axis (vertical, control unit at the top). The sampling pipe is then inserted into the detector housing from below. This makes it easier to feed the tubes to accessory parts such as filter-box/filter unit and water retaining box, which for physical reasons should always be below the ASD detector housing. If feeding the sampling pipe into the detector housing from above is unavoidable, the detector housing can also be rotated through 180° and then mounted (i.e. with the control unit at the bottom). To ensure that control unit labelling is not upside down, turn the control unit labelling strips accordingly (see Sec. 5.4.4).

To prevent the ingress of dirt, the detector housing ships fitted with the pipe plugs (tube network input). Likewise all the cable screw unions are sealed. If there is a return sampling pipe back to the monitored area, it can be connected directly to the detector housing in place of the air outlet pipe plug.

System performance depends on the sampling pipe. Any extensions or modifications to the installation may cause functional faults. The effects of such changes must be checked. It is very important to adhere to the spec fications in Sec. 4 (Planning). The “ASD PipeFlow” calculation software is available from the manufacturer.

5.5 Mounting the sampling pipe

5.5.1 General

The mounting and installation are to be carried out by analogy as specified in Section “Planning” in this document. Any deviation from the layout of the sampling pipe and sampling holes (also outside the limits calculated using “ASD PipeFlow”) is subject to the consent of the manufacturer.

The sampling pipe can be made of hard PVC or halogen-free ABS material, depending on requirements. In special applications – e.g. in extremely corrosive environments – other tube materials can also be used, subject to the specifications set out in Sec. 5.3.

Warning – installation and modification of the sampling pipe

5.5.2 Mounting with PVC tubes and fittings

As a rule, if the system operator does not specify a halogen-free installation, the sampling pipe can be made using hard PVC tubing. When PVC tube material is installed, the individual tube parts are glued together using a special PVC adhesive (e.g. Tangit for PVC). The adhesive manufacturer’s instructions must be followed. Before gluing, use household paper to remove any dust and grease deposits from the surfaces to be glued (do not use textile cloths). If the tube parts are very dirty, a cleaning agent as specified by the adhesive manufacturer may have to be used.

Danger

Notice

– ABS and PVC – must not be combined, since different adhesives are used.

5.5.3 Mounting with ABS tubes and fittings

If required, halogen-free ABS material can be used for the sampling pipe. When ABS tube material is installed, the individual tube parts are glued together with a special ABS adhesive (e.g. Tangit for ABS). The adhesive manufacturer’s instructions must be followed. Before gluing, use household paper to remove any dust and grease deposits from the surfaces to be glued (do not use textile cloths). If the tube parts are very dirty, a cleaning agent as specified by the adhesive manufacturer may have to be used.

5.5.4 Mounting with metal pipes and fittings

Metal tubes (copper, stainless steel) are connected using press fittings according to the manufacturer’s instruction s. For this purpose a special press tool can be obtained from the manufacturer on loan.

5.5.5 Linear expansion

Plastics have sizeable linear temperature expansion coefficient, which is why special attention should be given to the linear expansion (extension and contraction) of the sampling tube. An increase in temperature causes the tube to expand; a decrease in temperature causes it to contract. The importance of taking linear expansion into account increases as the temperature at the time of installation deviates from the usual operating temperature.

Linear expansion can be calculated as follows:

Notice

• Clips and pipe clamps at 1 m intervals are used to fasten the sampling pipe.

• The tubes must be cut to size using a pipe cutter. In doing so, ensure that the cut is at a right-angle to the tube axis. Remove any projecting burrs, Fig. 19.

• The ends of the individual tube pieces are to be bevelled slightly using a suitable tool, e.g. slightly bevel with a pipe scraper, Fig. 19.

• The individual tube sections are connected using fittings. Depending on the tube material used, use either the adhesive process described in Sec. 5.5.2 and 5.5.3 or the pressing process described in Sec. 5.5.4. The tubes are pushed into the fittings as far as the stop, Fig. 20.

• The connection points must be sealed tight to prevent the intake of any leakage air.

• If the sampling pipe or parts thereof is laid out vertically (e.g. in a riser or high-rack storage facility), make sure the tubes cannot slide down (secure clips directly below the fittings as shown in Fig. 21).

• The sampling pipe must be fastened so that the tube is able to “operate” within the clips (linear expansion, see Sec. 5.5.5).

• A distance of at least 0.2 m must be maintained from the T-piece to the clips, starting from the branching points of the sampling pipe, Fig. 22.

• For changes of direction in the space surveillance, it is advisable to use 90° bends rather than 90° angles, Fig. 22 (see also Sec. 4.4.2).

• For flush mounting or mounting in false ceilings, ensure that the tubes are not able to start oscillating by themselves.

• The exact definitive layout of the tubes – particul arl y in the case of flush mounting – must be documented precisely on the installation plans complete with dimensions.

5.5.7 Mounting for equipment monitoring

When mounting for equipment monitoring (EDP installations, electrical cabinets etc.), plast ic tube m aterials are to be used in principle. The same guidelines as described in Sec. 5.5.6 apply.

Equipment monitoring involves monitoring all the air outlet openings of the monitored devices. Whenever possible, the sampling pipe and detector housing are always secured directly to the object to be monitored.

5.5.7.1 Screw-free fastening of the sampling pipe

Use the click-on pipe clam ps to se cure the sampling pipe parts (sampling fixtures) without screws. This allows the sampling fixture or sampling pipe to be removed quickly during maintenance work on the monitored objects.

The click-on pipe clamps are screwed onto the support rails by means of threaded plates. The support rails are best fastened at right angles to the tube axis to ensure a precise positioning of the sampling pipe (sam-

pling fixture). Double-sided adhesive tape is used to secure the support rails in the desired position on the object, Fig. 23. Before using the double-sided adhesive tape, make sure the adhesion surfaces are cleaned with a non-aggressive cleaning

agent (e.g. soap suds or similar). Cable ties can also be used for securing purposes instead of the double-sided adhesive tape.

5.5.7.2 Transition to a flexible tube

With equipment monitoring, the transition from rigid to flexible tube can be made in principle using any type of fitting. The parts shown in Fig. 24 are used for that purpose.

For a rigid sampling pipe made of PVC a PVC threaded ring with M20 internal thread is glued into the exit side of the fitting. The M20 quick-release coupling is screwed into the adapter for the flexible tube.

If the rigid sampling pipe is made of halogen-free ABS, the procedure is identical to that for PVC. Instead of the PVC threaded ring, however, a suitable threaded ring made of AB S is used.

The flexible tube is simply snapped into the quick-release coupling and snapped out of it again just as easily for maintenance work.

5.5.8 Creating the sampling holes

The hole diameters for the sampling holes have to be determined and created by the customer as described in Sec. 4.4.4.4 and according to the specifications of the “ASD PipeFlow” calculation software or according to Sec. 0.

The sampling holes must be drilled cleanly so that no burrs or pressure points result. Use “new” drills with correctly ground surfaces (Fig. 25).

Whistling noises are a sign that the holes have not been neatly drilled. If so, the holes should be re-drilled an d/or deburred.

For space surveillance, the sequence of hole diameters set out in Sec. 4.4.4.4 and the specifications of the “ASD PipeFlow” calculation software must be observed strictly.

If required, the sampling holes can be made using the special “sampling hole clips” (see 5.5.9).

For equipment monitoring, the sampling holes are drilled in the sampling fixture. The sampling holes are drilled into the sampling fixture in the direction of the air outlet from the object to be monitored. If required, these sampling holes can be fitted with sampling funnels (Sec. 5.5.10).

Fig. 25 Creating the sampling holes

5.5.9 Mounting the sampling hole clips and mainten ance clips

Possible only with plastic tubes (PVC/ABS)!

At each required position in the sampling pipe drill a hole 8.5 mm in diameter (uniform Ø). The holes are made at right angles, in the centre of the pipe axis (as shown in Fig. 25).

The sampling hole clips are available in various sizes (Ø 2.0 / 2.5 / 3.0 / 3.5 / 4.0 / 4.5 / 5.0 / 5.5 / 6.0 / 6.5 / 7.0 mm). To determine the required sampling hole clips, refer to Sec. 4.4.4.4 and the specifications of the “ASD PipeFlow” calculation software or Sec. 0.

The sampling hole clips and the maintenance clips are clipped onto the sampling tube so they snap into the 8.5 mm borehole,

For equipment monitoring objects with a high air-flow rate (strong ventilation), the sampling holes can be fitted with funnels for optimal smoke detection. If forced ventilation is used in rooms and/or on equipment, the use of sampling funnels is imperative

The sampling funnels are secured to the tube of the sampling fixture and adjusted to the previously drilled sampling holes as described in 0 (see Fig. 27).

6.6.1 Power supply

The ASD 532 must always have an emergency power supply. Depending on the output current available at the fire alarm control panel (FACP) and the number of ASD 532 units to be connected, the power supply can be provided by the FACP; alternatively, an additional power supply must be provided locally. The supply is via terminals 1 and 2. In applications which stipulate a redundant power supply line (country-specific), it is routed to terminals 3 and 4 (Fig. 32).

6.6.2 Reset input

The reset input is potential-free (opto-isolator) and can be actuated on both the “plus” side and t he “minus” side, Fig. 33. The input operates in the 5 to 30 VDC range and in an impulse bandwidth of 0.5 to 10 s. Thanks to the continuous current consumption of approx. 3 mA across the entire operating range, actuation can be carried out directly via an OC output.

If a continuous signal is imposed for longer than 20 s, the ASD 532 is switched inactive, the fault relay becomes active (triggers), and the fan is switched off. Once the continuous signal is switched off, the ASD is re-armed. Switching inactive via the “Reset external” input works only if the ASD 532 is not equipped with an XLM 35.

6.6.3 Control

The ASD 532 units connected to an FACP are controlled according to the detection zone mapping using the FACP states “Zone On/Off” and “Reset”. Two possibilities are available:

• Control via supply voltage (auxiliary relays in the ASD power supply line);

• Control via the “Reset external” input

6.6.3.1 Control via voltage supply by means of auxiliary relay

Depending on the location of the ASD power supply, the auxiliary relay may be placed in the FACP or directly in the ASD

532. The auxiliary relay can be actuated in the following ways (see

Fig. 34): A. line plus or minus B. SW output of the FACP C. SW output or function of a control module

7.1 General

The ASD 532 is to be commissioned by trained and qualified personnel only. Prior to commissioning it is important to ensure that the entire sampling pipe has been laid correctly (junctions, sampling h oles). If a maintenance sampling hole is provided as described in Sec. 4.4.4.6, it or the maintenance clip. Prior to commissioning, an inspection of the mounting and installation must ensure that when the power supply is switched on there can be no damage to the ASD 532. Rewiring the device may be performed only when voltage is disconnected. Exception: Logging off additional modules XLM, RIM and SIM (see Sec. Before switching on, the smoke detector and any additional connected to the AMB 32 main board by means of the supplied flat cable. See also Sec. 6.3 and 6.4. Before switching on the ASD power supply, ensure that all fire incident controls and remote alerting from ASD 532 are blocked or deactivated. Immediately before switching on the ASD 532 for the first time, remove the isolating strip from the lithium battery (AMB 32).

7.2 Programming

The ASD 532 has several switch positions that are configured with permanently assigned parameters:

• normative system limits according to EN 54-20, Class A to C, switch positions A11 to C31;

• Non-normative syste m limits, switch settin g s W01 to W44;

• Configurable switch positions for saving the settings after using “ASD PipeFlow” and/or changing the device configuration

using the configuration software “ASD Config” or SecuriFire or Integral-FACP (XLM 35), X01 to X03. A detailed description of all switch positions is in Sec. 8.3. If the ASD 532 is operated with EasyConfig, i.e. within the preset system limits according to the tables in Sec. 4.4.4.3 and

4.4.4.4, then only switch settings A11 to C31 and W01 to W44 are to be selected; it is not necessary to use the “ASD Config” configuration software.

In systems where the sampling pipe planning was performed with the “ASD PipeFlow” calculation software, the response sensitivities of the smoke sensors calculated by “ASD PipeFlow” have to be programmed on the ASD 532 with “ASD Config”. The data is saved on the ASD 532 under one of the freely configurable switch positions X01 to X03. The ASD 532 is then operated on the switch positions X01 to X03.

The device ships with default values already stored under switch positions X01 to X03. Specifically:

• position X01 with position A11;

• position X02 with position b11;

• position X03 with position C11;

The following parameters can be modified using the “ASD Config” configuration software (see Sec. 7.2.1):

• Smoke sensor alarm thresholds;

• Trigger thresholds for dust and dirt (individually);

• Trigger thresholds for pre-signals 1, 2 and 3 (individually);

• Delay times for dust/dirt, pre-signal, alarm and fault (individually);

• Sensitivity and delay time of the airflow monitoring;

• Deactivate latching for dust/dirt, pre-signal, alarm and fault (individually);

• Deactivate criteria (pre-signals, dust/dirt, faults);

• Fan speed

• Date/time

• Autolearning (On/Off, duration);

• Day/night operation

7.3.5 Initial reset

When com missioning the ASD 532, an initial reset is required. When this happens, the airflow monitoring is automatically aligned to the connected sampling pipe.

In principle the initial reset should be carried out under “normal system conditions” systems, air conditioning syste ms, etc. , running in “normal operation”. If a maintenance sampling hole is provided, it must be closed with adhesive tape or the maintenance clip. The initial reset must be performed with normal ventilation for equipment monitoring of ventilated objects. If there is an expansion, conversion, retrofitting or repair on the sampling pipe, an initial reset is imperative. An initial reset must be performed after the fan speed has been changed. After an FW upgrade, an initial reset is required only if expressly mentioned in the relevant firmware description. Before performing an initial reset after switching on the ASD 532, a waiting time of at least 2 min

7.3.7 Logging off additional modules XLM 35, RIM 36, SIM 35 and the SD memory card

The additional modules (XLM 35, SIM 35, RIM 36) or the SD memory card are automatically detected when the device is switched on; from that point onwards, they are monitored and fully functional. The SD memory card begins with data logging, recognisable on the flashing Com LED on the AMB. To eject the SD memory card or remove a subsequently fitted additional module (e.g. because it is not being used), the additional modules and SD memory card must first be logged off via the AMB 32 main board.

When changing parameters as described in Sec. 7.2.1 and 7.2.2, use the “ASD Config” configuration software.

7.4.3 Re-programming from SecuriFire / Integral with XLM 35

When connecting to the SecuriFire or Integral FACP via an XLM 35, control operations and changes can be made to the ASD device configuration directly from the FACP. For this purpose the FACP user software “SecuriFire Studio” and “Integral Appli-

cation Center” are used to start the “ASD Config” configuration software for access to the ASDs; the configuration software is

then used to make changes to the ASD 532.

(over 30 Voltage values that are too low can be caused by insufficiently

rectly set FACP voltage.

7.6 Measurements

The ASD supply voltage on terminals 1 and 2 must be checked (check also terminals 3 and 4 in the case of a redundant supply). The voltage must be between 17.6 and 27.6 V for a correctly set FACP voltage supply (not emergency current operation). The value depends on the line length. Once commissioning is completed, the measured voltage value is to be entered in the commissioning protocol (see Sec. 7.8).

With the conductor cross-section determined and installed as described in Sec. 4.8.2, this voltage range must always be available at the end of the electrical ins ta ll a tio n – i.e. at the ASD 532 – to ensure that the ASD 532 is able to operate fault-free (see also Sec. 4.8.2).

Danger

If genuine fire tests are to be carried out, the relevant local authorities (fire service) are to be consulted b forehand; the tests themselves are to be carried out by trained specialists (manufacturer) only.

7.7 Testing and checking

In addition to the sampling pipe checks set out in Sec. 7.1, the correct transmission of alarms (zone and line) on the FACP is to be checked by triggering faults or alarms on the ASD 532. These tests are to be entered in the commissioning protocol (see also Sec. 7.8).

7.6.1), the “Fault” LED begins to flash.

7.7.1 Checking the alarm release

When commissioning and after any changes (repairs) to the sampling pipe the alarm release must take place fro m the last sampling hole on the pipe branch. This tests the uniformity throughout the entire sampling pipe.

To test alarm actuation during regular maintenance and service work, the ASD 532 can be made to actuate on the mainte- nance sampling hole. Because the sampling pipes are continuously monitored for proper functioning, testing via the sampling

pipe is normally not necessary. Once the test is completed, re-seal the maintenance sampling hole (using adhesive tape or maintenance clip).

If testing via the maintenance sampling hole is inadequate, testing can be carried out via the sampling pipe as follows:

• Point-by-point testing of the sampling holes; apply smoke directly to individual or several sampling holes. Apiarist smoke or wax/joss sticks are suitable for this purpose.

• Area-wide testing of the sampling pipe; area-wide testing of the sampling pipe using fire tests is reasonable and practicable only following EN 54-20.

8.2 Functional sequence of operation

Events triggered on the ASD 532 can be reset locally using the “Reset” key on the control unit or by briefly actuating the “Reset External” input. The reset is possible only if the triggering event is no longer pending (e.g. smoke sensor no longer has smoke). The application of a continuous signal at the “Reset external” input also deactivates (switches off) the ASD 532 (see also Sec.s 2.2.6 and 6.6.2).

These elements are used when commissioning the ASD 532. Device settings for predefined system limits can also be called up – EasyConfig. These pre-defined positions are stored with normative values for response sensitivity, airflow monitoring (LS-Ü) and pipe configuration. They also contain positions which allow deviations from the normative limits with regard to airflow monitoring. The EasyConfig process allows the device to be commissioned without the “ASD Config” software. If system- specific programming has to be carried out (e.g. after a calculation with “ASD PipeFlow” or when programming RIM 36), the “ASD Config” configuration software must be used.

8.5.2 Indicators on the AMB 32 main board

Besides the segment display the AMB 32 Main Board has various LEDs, with the following meaning (see also Fig. 45):

• Flashing point on the left-hand segment display = watchdog display (processor is running)

• Flashing on the segment display, point and AL = Autolearning is running;

• On the segment display, flashing point on the left, point steady lit on the right = day/night control active (in X01 – X03 only);

• LED ”WDog” = watchdog display (processor not running  ASD has triggered a fault);

• LED CardOk = SD memory card present

• LED Com = communication with the SD memory card.

Other output and display possibilities on the segment display include:

• in switch position E = event memory, see Sec. 8.5.3;

• in switch position F = firmware version, see Sec. 7.3.6;

• Push button “UP” = the set configuratio n (A11 to C31, W01 to W44, X01 to X03), see Sec. 7.6.1;

• in switch position V = airflow values (volume rate of flow), see Sec. 7.6.1.

8.5.3 SD memory card operation

The SD memory card is automatically detected when the device is switched on and when the card is inserted. From then on it is monitored. Data logging begins automatically after approx. 10 s.

Only industrial SD memory cards tested and approved by the manufacturer may be used (see Sec. 12.1 use of a consumer SD memory card is to be avoided – SD memory card and faults on the ASD. Inserting the SD memory card: Before using the SD memory card, make sure it is blank (file interpretation). Removing the SD memory card: To avoid data loss, log off the SD memory card on the AMB 32 (switch posi-

The SD memory card is inserted with the contact side facing toward the LMB circuit board and pushed into the holder until it snaps into place. Pressing the SD memory card again releases the locking mechanism and the SD memory card can then be removed from the holder.

8.5.3.1 Data logging on the SD memory card Smoke level and airflow values: The smoke level and airflow values as well as the current status of the sampling tube net-

work are written to the SD memory card every second (default, can be changed with ASD Config) and saved in Log-Files (*.xls file). After 28,800 entries (corresponding to 8 hours with a logging interval of 1 s) a new ated. A total of 251 log files (L000.xls to L250.xls) can be generated for long-term logging. After the last log file the oldest one (L000.xls) is overwritten. The 251 Log-Files

log files can be opened in Excel and the data processed with the diagram assistant to create charts.

Events: All events occurring in the ASD 532 are written to the Event-Files (*.aev file). After 64,000 events a new Event-File is created automatically. A total of 10 Event-Files (E000.aev to E009.aev) can be generated for long-term logging. After the last

The event memory can be called up via switch position E. Up to 99 events can be stored in the event memory (E01 to E99), with event E01 as the latest (more recent) event. If the memory exceeds 99 events, the oldest event is deleted. The event memory as a whole can be deleted only by the manufacturer.

Events are subdivided into groups (G00 to G99) so they can be displayed using the 3 digits of the segment display. For each event group, up to 8 events can be displayed as a 3-digit code. The codes are added together and displayed if there are multiple pending events per event group.
