General Product identification For identification purposes, the ASD 531 and its units have rating plates or identification plates. The following product identifications apply: Rating plate on the ASD 531 and identification on the packaging Manufacturer Type designation 3052 Zollikofen / Switzerland...
The use of third-party detectors voids the ASD 531 approval issued by the manufacturer. The ASD 531 is fitted with the SSD 31 smoke sensor by the manufacturer. It has an alarm sensitivity range of 0.02%/m to 10%/m.
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 531.
2.2.1 Power supply The operating voltage of the ASD 531 is +14 to +30 VDC. On the AMB 31 Main Board, 5 VDC of the operating voltage is di- verted for internal voltage use. The operating voltage is monitored on the AMB 31 for undervoltage. If the operating voltage falls below 13 VDC (+0 / –0.3 VDC), the ASD 531 triggers an undervoltage fault.
A specially designed circuit therefore ensures that the fan cannot exceed a specific maximum power consumption in its start- up phase. When the ASD 531 is switched on, the computer-controlled fan speed starts up slowly. After the fan has been pow- ered up, the speed is kept constant.
(on “Reset external” input of the ASD 531). Events triggered on the ASD 531 can be reset locally using the “Reset” key on the control unit or by briefly actuating the “Re- set External” input. The reset is possible only if the triggered event is no longer pending (e.g. smoke sensor no longer has smoke).

(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 s. When a continuous signal is applied for longer than 20 s, the ASD 531 is deactivated (fault state) (see also Sec.
Smoke sensor monitoring The smoke sensor used on the ASD 531 is monitored on the AMB 31 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 31 is monitored and a fault is signalled if there is a failure.
Fault triggering If a fault occurs on the ASD 531, the “Fault” relay is de-energised and the “Fault” display is activated. With the SD memory card, the fault profile can also be used in the event of a fault (see also Sec. 8.5.4.3 and 10.3.1). The following events trigger a fault (list is incomplete): •...
A hardware reset is triggered if there is a brief interruption in the supply voltage or if the “HW reset” key is briefly pressed on the AMB 31 (see also Fig. 40 and Fig. 44). This restarts the ASD 531. The fan stops and then slowly starts up again (start-up control).
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 531 is able to remain fully operational during commissioning and maintenance work even when the housing cover is open.
Design Electrical The electrical design of the ASD 531 includes the following (may vary depending on the device version): • AMB 31 Main Board • Smoke sensor (SSD 31) • • Air flow sensor • Additional modules XLM 35, RIM 36.
T 131 194. Materials from other sources may be used only if the manufacturer’s written consent has been obtained. A special tool is required for mounting and handling the ASD 531 (Torx screws). Please refer to the list in Sec. 5.1. Packaging The detector housing is delivered in a customised cardboard sleeve sealed with adhesive tape.
Standards, regulations, guidelines, approvals Sec. 4 “Planning” below is a guideline for planning the ASD 531 aspirating smoke detector. These guidelines address the di- rect application only insofar as it applies to compliance with EN 54-20 and is required to ensure technically trouble-free opera- tion.
System limits The use of an ASD 531 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 also apply.
4.3.2 Planning without “ASD PipeFlow” calculation If planning is performed without “ASD PipeFlow”, a number of switch settings in the ASD 531 are saved with pre-defined val- ues which are necessary for actuation in compliance with EN 54-20, Class A–C.
The following principles apply to space monitoring: • The number and arrangement of the ASD 531 units are based on the size of the space. • In general the monitoring areas are the same as for point-type detectors. Directives that apply to specific ob- jects –...

The definitions of the pre-defined settings and the operator structure are found in Sec. 4.4.4.2, 7.2.1 and 8.3. Depending on the use of the ASD 531, it may be necessary to make adjustments to the airflow monitoring using the “ASD Config” configuration software. These adjustments relate merely to the size of the monitoring window (pipe breakage/pi- pe blockage) and the fault delay time (time until the exceeded monitoring window is reported as a fault).
In areas with high-energy devices and installations (generators, power plants, railway facilities, X-ray equipment, etc.). Outside buildings. If screening is used, the cable screening in the ASD 531 is to be connected to an additional support terminal. The cable screening must not be connected to the minus or ground terminal of the AMB 31.
When determining the conductor cross-section, the highest possible power consumption by the ASD 531 during normal opera- tion (after switching on) is the decisive factor. Due to its circuitry design, the ASD 531 has the highest power consumption at the minimum supply voltage, i.e. at 14 VDC.
Planning Restrictions Notice The following restrictions apply to the use and application of the ASD 531. For other solutions, please consult the manufacturer. General information and space surveillance: • The sampling holes of the tube network and the detector housing must be in the same climate zone (pres- sure/temperature zone) (sampled air may have to be recirculated to the other climate zone).
Environmental influences Danger On the basis of the conducted tests, the ASD 531 may be used in an environment that is within the scope of the type approvals. The environmental conditions as described in Sec. 13 must also be observed. Non-observance can negatively impact proper functioning of the ASD 531.

For this reason, prior to working with these materials it is imperative to read and observe the safety in- structions and information provided by the adhesive supplier. A list of the available materials for the sampling pipe (pipes, fittings etc.) for the ASD 531 is available in a separate docu- ment (T 131 194).
The return line can be adapted after removing the air outlet pipe plug on the ASD 531 housing. See also under Sec. 4.5, 5.4.2 and 5.4.3. The maximum length for the return line must not exceed 20 m.
Notice When mounting several ASD 531 units next to one another, make sure that the mounting holes are drilled pre- cisely. The device can be shifted by a maximum of ±2 mm horizontally and vertically to correct its mounting posi- tion.
The air outlet pipe plug (with openings) is to be fitted to the air outlet opening only. • The pipe plugs must not be glued in the ASD housing (plug-in connector). ASD 531, Technical description, T 140 416 en 53 / 105...

Cable entry Danger Make sure the power is disconnected for all connection and wiring work on the ASD 531. There are two M20 cable screw unions in the detector housing for feeding in the electrical installation. If needed, an additional two cable screw unions (1 x M20, 1 x M25) can be fitted in two reserve holes (blind plugs).
Deploying smoke sensors The ASD 531 ships with the smoke sensor already fitted. The smoke sensor has to be removed from the detector housing for the installation of the ASD (release the two lock clamps); however it should be left inside its protective packaging until the de- finitive commissioning.
Danger Inside the detector housing the lines should be fed to the terminals using the shortest possible route. Reserve loops via the main board are to be avoided (EMC). ASD 531, Technical description, T 140 416 en 65 / 105...

The information on operation and display elements necessary for startup can be found in Fig. 41. Warning Before the ASD 531 is switched on, all the precautions required for operation as described in Sec. 7.1 must be fulfilled. ASD 531, Technical description, T 140 416 en...
Setting the alarm threshold without “ASD Pipeflow” calculation The following describes the procedure for setting the ASD 531 to one of the switch positions with fixed parameters A/1 to CC. Example: The ASD 531 is to respond in compliance with EN 54-20, Class B. The sampling pipe is U-shaped with 3 sampling holes per sampling branch.
The following work flow describes the procedure for setting air flow tolerance and delay time of the ASD 531. Example: ASD 531 is to trigger a fault if there is a deviation of ±30% after 20 min. Perform the settings as described in Sec.
Isolate device This function is used to place the ASD 531 in an isolated state. In this way test alarms can then be triggered on the ASD 531 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.
Switch device inactive This function switches off the fan and sensor of the ASD 531. The ASD 531 is then no longer capable of an alarm. An inactive ASD triggers a fault and signals the superordinate unit (FACP) accordingly. On the ASD the “Fault” LED is then continuously lit.
The parameters are configured ex factory with default states and values so that the triggering properties comply with EN 54-20. Changing the parameters may result in non-compliance with EN 54-20. Adjustments and modifi- cations to the ASD 531 may be carried out only by the manufacturer or by trained technicians. 7.4.1...
With the conductor cross-section determined and installed as described in Sec. 4.8.2, this voltage range must always be avail- able at the end of the electrical installation – i.e. at the ASD 531 – to ensure that the ASD 531 is able to operate fault-free (see also Sec.
According to EN 54-20 a change in the airflow that is greater than ±20% must be reported as a fault. After an ini- tial reset, the airflow shows 100% in the ASD 531 aspirating smoke detector when the sampling pipe is correct and clean.
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 531. These tests are to be entered in the commissioning protocol (see also Sec.
Notice about test triggerings Fire incident control and remote alerting must be blocked or deactivated on the superordinate FACP. Reset the ASD 531 between each check (preferably on the FACP, as a reset on the ASD does not reset the FACP).
Fig. 44 View of the operation and display elements The control unit has a “Reset” key for resetting triggered events (alarms/faults) directly on the ASD 531. Three rotary switches and two DIP switches are inside the device on the AMB 31 main Board as well as three LEDs.
(on “Reset external” input of the ASD 531). Events triggered on the ASD 531 can be reset locally using the “Reset” key on the control unit or by briefly actuating the “Re- set External” input. The reset is possible only if the triggered event is no longer pending (e.g. smoke sensor no longer has smoke).
(e.g. smoke level in the smoke sensor is once again below the trigger threshold, or a fault event is rectified). As a result of the reset, the ASD 531 continues to run “normally” and the fan does not stop.
