VESDA VLC-500 and VLC-505 LaserCOMPACT Instruction Manual

VESDA VLC-500 and VLC-505 LaserCOMPACT

Introduction

The VESDA VLC detector has been specifically designed to provide all the benefits of aspirating smoke detection, including very early warning, in single environment small areas and where space is a premium. The VLC combines the well-proven VESDA VLP detection technology with a modified aspirator design, and incorporates them into a compact enclosure with a simplified display.

Two variants and a remote display option
The VLC is available in two versions, one that interfaces via relays only (RO) and one that interfaces via relays and VESDAnet (VN).
The VN version is compatible with the remote Display Module, which allows the current status of the detector to be reported in the most convenient location. The remote Display Module has 7 remote relays to support any combination of signalling that may be demanded by the application. The VN version allows several detectors to be linked together on VESDAnet thereby allowing one to act as a reference detector for other VESDA detectors.

Description

The VLC is made up of two parts: the main enclosure and the front cover. The main enclosure houses all the key components of the detector. All non- serviceable items like the main processor board and detector chamber are mounted away from the general access area, protecting them during the installation and service process.

The front cover includes:

• 5 LEDs : Fire, Pre-Alarm/Alert, Fault, OK, Reset/Isolate
• Reset/Isolate Push Button (press to reset, press and hold to isolate)

Features

• Absolute smoke detection
• Wide sensitivity range
• Single pipe inlet
• Five (5) status LEDs
• Referencing
• VESDAnet communication (VN)
• Clean air barrier optics protection
• Three (3) Alarm Levels
• Three (3) Programmable Relays
• Air flow monitoring
• Optional remote display and relay capability
• Simple mounting design
• AutoLearn™
