    This makes the system very easy to have unwanted or false alarms. The prefer detection zone size of VDOT-ASD-100 is only about one quarter to one half of that of the popular product on market (typically 2000sqm); while it provides much better performance of very early fire detection and better ability immune to false/unwanted alarms.

  • Page 8: Sampling Pipework Design

    VDOT-ASD-100 Aspirating Smoke Detector User’s Manual V1 Sampling Pipework Design Aspirating system design is inherently simple. It is often possible to achieve good system performance with very simple installations. There are however a few rules, which must be adhered to, and these rules are equally applicable to all aspirating systems. The information contained in this manual is intended as an overview only.

See Relative Sensitivity below. Maximum Permissible Transport Time The time taken for a system to transport a sample from a protected area should not exceed 120 seconds (2 minutes).

  • Page 11: Design Guidelines

    Maximum pipework limitation The limitation of each pipe inlet of VDOT-ASD-100 when the aspirator speed set to 10 is 100m pipe length with up to 18 holes alone the pipe (maximum pipe length) or 60m pipe length with up to 25 holes along the pipe (maximum holes) under the requirement of 120s maximum transport time.
  • Page 12 VDOT-ASD-100 Aspirating Smoke Detector User’s Manual V1 This guide holds true for average sampling pipe lengths, but if using long pipes (typically more than 60 meters total), performance may be improved by making the sampling holes near the ends slightly larger than those nearer the detector.

    VDOT-ASD-100 Aspirating Smoke Detector User’s Manual V1 Installation Note: It is recommended that the installation is carried out by suitably experienced and trained personnel. Mechanical Installation Dimensions The mounting holes in each corner are used to mount the device on the wall. It is recommended the device is 1.5m above the floor.
  • Page 15 VDOT-ASD-100 Aspirating Smoke Detector User’s Manual V1 Ensure that when the detector is fitted to the wall there is enough space on the right-hand side to allow the opening of the front panel. Cable entries are also provided on the side and bottom. It should be noticed that some cable entries are non-cut through holes, a punch using a screwdriver and hammer or a proper tool are needed to open the entry holes.

    Flow Sensor Termination Board Filter High Sensitivity Smoke Detector Above picture is the internal view of the VDOT-ASD-100. All the electrical connections should be made to the removable connectors on the termination board or the relay board if it equipped. Cables Power cable should be 2.0mm -2C of sufficient current carrying capacity.
  • Page 17 VDOT-ASD-100 Aspirating Smoke Detector User’s Manual V1 Terminal Connections Termination Board Power Supply Connections Two 24Vdc power terminals on the termination board. One must be connected to a 24±20% (19.6~28.8) DC Power Supply. The device may be powered by any EN54-4 compliant monitored 24DC power supply of sufficient capacity.
  • Page 18 GPI, General Purpose Input There are eight General Purpose Input terminals on VDOT-ASD-100 termination board. Those inputs are designed to monitor the status of the connected devices. The connected devices monitored by the GPI can be just a button, a fault relay from the power supply, or even alarm relay from other detector.
  • Page 19 The UDI, User Defined Input is usually used to monitor the status (relay) of other detection device, like gas sensors, temperature sensors, or other aspirating smoke detectors. The GPI-1 on the VDOT-ASD-100 termination board is a monitored contact with a 10KΩ terminal resistor connected at the factory. When the GPI-1 is used, the terminal resistor needs to be moved to the end of the line.

To enable the GPI-2, mount both the P1 and P2 jumper selection to 2/3 PIN and set the corresponding GPI function. When the external active input is disconnected for less than 3 seconds, the corresponding GPI-2 function is activated, and when the GPI-2 connection line is disconnected or open for more than 6 seconds, the GPI-2 fault is reported.

  • Page 35: Maintenance

    VDOT-ASD-100 Aspirating Smoke Detector User’s Manual V1 Maintenance VDOT-ASD-100 aspirating smoke detector is a very low maintenance detection system. If required, external cleaning of the unit should be performed using a damp (not wet) cloth. Do not use solvents as these may mar the display bezel. The only part that may require field replacement during servicing is the dust filter.
