Page 9: General Information
This defines heating element control (relays, subsequent heating time). The response behaviour of the ASD 535 has been tested in compliance with EN 54-20, Class A, B and C. With the ASD 535, deep-freeze warehouses can be monitored in accordance with response classes B and C in compliance with EN 54-20. -
Page 10: Function
Heating element power supply Control of the heating elements is realised by means of a relay (relay 3 of the AMB 35 for ASD 535-1 / -3 or relay of RIM 35 for ASD 535-2 / -4) for each sampling pipe tube network (I / II). The relay has to be programmed using the “ASD... -
Page 11: Planning
These guidelines deal with the application as concerns the fulfilment of EN 54-20 and are intended to ensure technically trou- ble-free operation. The ASD 535 aspirating smoke detector conforms to the requirements of European Standard EN 54-20, Class A to C. The fol- lowing applies: •... -
Page 12: Planning With The "Asd Pipeflow" Calculation Software
Planning with the “ASD PipeFlow” calculation software When setting up a system for deep-freeze warehouses with ASD 535, it is not imperative that the “ASD PipeFlow” calculation software is used. If, however, “ASD PipeFlow” is used, the system limits in Sec. 3.5 must be adhered to. -
Page 13: System Limits For Deep-Freeze Warehouses Without "Asd Pipeflow" Calculation
System limit 1, 2, 3 (tube network length, number of sampling holes) • Third digit Tube networks 1, 2 (number of sampling pipe tube networks on the ASD 535). Example: b22 response class b / system limit 2 / 2 sampling pipe tube networks. -
Page 14: System Limit Table For Planning Without "Asd Pipeflow" Calculation
The specifications are valid with and without detector box (REK, max. 2 units) and small filter-box FBS 25 PC. • If a filter-box is used, it must always be installed within the first 2 m from the ASD 535. 14 / 31... -

If the “ASD PipeFlow” calculation software is used, the sampling hole diameters in the table above (Sec. 3.7) must be used in “ASD PipeFlow”.

Page 17: Sampling Point With Heating
Electrical installation As a rule, the power supply for the heating elements is the same as for the ASD 535 supply from the fire alarm control panel (FACP). However, this is possible only when the ASD 535 is operated with 24 VDC, since otherwise the heating elements would not be able to provide the necessary heating performance. - Page 18 When determining the conductor cross-section, the highest possible power consumption of the ASD 535 during normal opera- tion (after switching on) is the decisive factor. Due to its circuitry design, the ASD 535 has the highest current consumption at minimum supply voltage, i.e. in 24 VDC operation at 18 VDC.
-
Page 19: Power Calculation
Power calculation For maximum power consumption of an ASD 535 with heating elements, besides the ASD type (-1, -2, -3, -4) the number of present sampling points is also decisive. To simplify the calculation, the value of the ASD 535-4 can be used (system with the highest power consumption including one RIM 35). -
Page 20: Mounting And Installation
For this reason, prior to working with these materials it is imperative to read and observe the safety instructions and information provided by the adhesive supplier. A list of the available materials for the sampling pipe (tubes, fittings etc.) for the ASD 535 is available in a separate docu- ment (T 131 194). -
Page 21: Mounting The Detector Housing
Mounting work on the detector housing is best done without fitted smoke sensors. • The smoke sensors are always installed in the detector housing just prior to commissioning the ASD 535. • Depending on the situation (e.g. if there is a long time between mounting and commissioning or if for example the environment is very dusty due to construction), the housing cover should be kept closed until commission- ing the device. -

Fig. 4 Heating element wiring So that only two silicon Litz wires have to be fed in from the ASD 535 for U-, T- and H-shaped sampling pipes, a CCF 25 cable connection fitting must be installed directly next to the branching point (T piece). There the three wire pairs are gathered to- gether, Fig. -

If a small FBS 25 PC filter-box is used, it must always be positioned between the detector housing and WCU 535. The electrical installation of the heating control is performed from the relay in the ASD 535 and is conducted by means of a round cable via cable screw union to the WCU 535 wiring connection unit. -
