  • Page 5 Relays used on the detector are marked “TX2-5V”, “G6S-2-5V” or “EC2-5NU”. VESDA detectors must not be connected or disconnected to a PC while the equipment is powered in an FM Division 2 hazardous (classified) location (defined by FM 3611).
  • Page 6 Through validation testing, Underwriters Laboratories Inc. has verified that VESDA ECO gas detectors, when installed within the sample pipe network, present no significant effects on the smoke detection performance of VESDA. The use of the ASPIRE calculation software is required to verify system design performance with all devices included in the design.

    It provides localized fire risk management solutions for small, critical environments. The VLF-500 monitors areas up to 500 m² (5380 sq. ft.) dependant on local codes and standards. The VESDA VLF complements the existing VESDA detector range and has been designed to provide simple installation and commissioning, absolute smoke detection and reliable and consistent response to smoke events without being affected by false alarms.

  • Page 12: Mounting

    VESDA VLF-500 Product Guide VESDA by Xtralis Mounting The VESDA VLF can be installed upright, inverted or horizontally. Note: Ensure the smoke detector is mounted away from obstructions and below ceiling level. Caution: An exhaust deflector must be fitted for upright mounting, unless the exhaust port is connected to a return air pipe.

  • Page 13: Installing The Detector

    VESDA by Xtralis VESDA VLF-500 Product Guide Installing the Detector In all installation cases the mounting bracket must be fitted (upright) as shown in Figure 2-4 on page 8. Note: Ensure the mounting surface is flat. This will permit an air tight seal to be achieved between the sampling pipe and the tapered air ports on the detector.
  • Page 14 VESDA VLF-500 Product Guide VESDA by Xtralis 2.3.1 Installation Procedure Cut the air inlet pipe and exhaust pipe (if used) at 90°, and to the same length (for normal and inverted mounting). Remove all rough edges. This is critical to obtain an air tight seal with the smoke detector.
  • Page 15 Il convient de prendre des précautions contre les décharges électrostatiques avant d'enlever le capot avant du détecteur. For inverted mounting applications, the VESDA VLF will require the user interface display to be turned through 180°. This is carried out prior to installing the detector. Also refer to Figure 2-4 on page 8.

    VESDA VLF-500 Product Guide VESDA by Xtralis Detector Removal Caution: Electrostatic discharge precautions need to be taken prior to removing the front cover from the detector otherwise damage may occur to the unit. Attention : Il convient de prendre des précautions contre les décharges électrostatiques avant d'enlever le capot avant du détecteur, sinon l'appareil risque d'être endommagé.

  • Page 17: Air Inlet Pipe Connections

    Do not glue the air inlet pipe to the detector. This will void your warranty. Exhaust air pipe connections Where the VESDA VLF is located outside the protected area, consideration must be given to returning the exhaust air to the protected environment to balance pressure differences that may exist between the two areas.

  • Page 18: Wiring Connections

    2.7.1 Detector cabling requirements The screw type terminals located on the termination card within the VESDA VLF will accept wire sizes from 0.2 mm² to 2.5 mm² (30 – 12 AWG). Refer to Codes and Standards Information for Air Sampling Smoke Detection on page iii for code-specific requirements.
  • Page 19 End of Line (EOL) resistor is supplied with the product and must be assembled in parallel with the device to be monitored. The EOL resistor provides a known termination to the external equipment, this allows the VESDA VLF to detect open or short circuits. The detector monitors the EOL resistor (Figure 2-10) and reports any faults when the GPI function is set to any value, except None.

  • Page 25: Sampling Pipe Network Design

    The VESDA VLF supports a number of pre-engineered pipe network designs to simplify installation. The pre- engineered pipe networks have been designed with pressure, flow and transport time considerations. They have been verified and are shown below. For setup details refer to the VESDA System Design Manual. The pre-engineered designs assume the following constraints: 1.

  • Page 28: Return Air Sampling (Return Grilles)

    The VESDA VLF is suitable for air sampling across return air grilles of Air Handling Units. The recommended coverage of the VESDA VLF is 0.4 m² (4 sq. ft.) per sampling hole. This should be considered in conjunction with local codes and standards.

  • Page 31: Commissioning

    Commissioning General The VESDA VLF has been designed to simplify commissioning processes. The AutoLearn function allows the unit to assess its environment and setup appropriate alarm and flow thresholds. The unit may also be programmed through Xtralis VSC software, for all programmable settings. For further information refer to Chapter 7 on page 37.

  • Page 32: Autolearn Flow

    AutoLearn Flow process is initiated by pressing the recessed button numbered 2, which is located under the field service access door. During the AutoLearn Flow process, the VESDA VLF determines the average and peak air flow levels monitored over time and sets suitable air flow thresholds that will not give rise to false flow rates due to normal flow variations (such as might arise through air-conditioning related false alarms).

    You have not pressed BOTH the RESET button and the DISABLE buttons simultaneously, you have ONLY pressed the DISABLE button. To put the VESDA VLF into STANDBY you press and hold down the DISABLE button until the AutoLearn LEDS and DISABLED LED blink. This means keeping the button pressed for about 6 seconds.
  • Page 62 VESDA by Xtralis Can the deflector be removed from the VESDA VLF exhaust? It is a tight fit but it can be removed. With all VESDA detectors, we recommend returning all sampled air from the exhaust into the sampled environment.
