It is assumed that anyone using this manual has knowledge and the appropriate certification from the local fire and electrical authorities.
  • 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 ASPIRE2 calculation software is required to verify system design performance with all devices included in the design.

  • Page 9: Introduction

    VESDA VLP Product Guide Introduction The VESDA VLP is an aspirating smoke detector providing very early warning of fire conditions by drawing air samples through an air sampling pipe network. The detector chamber can detect presence of smoke at very low concentrations. The embedded and PC software complimenting the VESDA VLP provides a wide range of user defined parameters and reporting capabilities.

  • Page 11: Operation

    Operation An air sampling pipe network collects air samples from a protected area. The integrated aspirator draws air into the sampling pipes through a pipe inlet manifold. Up to four pipes can be connected to a VESDA VLP detector. Inside the VESDA VLP, a sample of air is passed into the laser detection chamber. Ultra-fine air filtration provides very clean air to protect the optical surfaces inside the detector from contamination.

    Display Module The VESDA VLP Display Module is mounted either on the detector front cover or at a remote location in a remote mounting box or a 19” subrack. It provides a visual representation of the smoke levels and the four alarm stages for the assigned detector.

  • Page 25: Mounting The Vesda Vlp

    Mounting the VESDA VLP The VESDA VLP detector can be mounted onto the wall or on any suitable secure surface using the mounting bracket. It is strongly recommended that the detector is mounted on to the mounting bracket included with the packaging.

  • Page 26: Mounting The Vesda Vlp In The Inverted Orientation

    If the detector is fitted with a LCD Programmer and/or a Display Module, re-orient these to the upright position. Mount the detector in inverted orientation onto the mounting bracket. Figure 4-3: Mounting the VESDA VLP detector in inverted orientation onto the mounting bracket Mounting the VESDA VLP without a mounting bracket In the event the detector has to be mounted directly onto the mounting surface, remove the chassis from the mounting box.
