1. Uvod i krajview
The VESDA VLF-500 detector is a very early warning smoke detector designed to protect small, business-critical environments of less than 500 m2 (5,380 sq. ft.). This advanced system continually draws air into sampling holes within a pipe network. The collected air is then filtered and passed into a detection chamber where sophisticated light scattering technology accurately identifies the presence of even minute amounts of smoke. Detector status information is clearly communicated on the device's display and can also be transmitted via relays or optional interface cards, ensuring timely alerts and system integration.

4. Postavljanje i instalacija
Proper installation is critical for the effective operation of the Vesda VLF-500-00 detector. Refer to the detailed installation instructions provided in the separate Product Guide for specific wiring diagrams and pipe network design guidelines.
4.1 Montiranje detektora
- Odaberite lokaciju: Choose a suitable location that complies with local fire codes and provides optimal air sampling coverage for the protected area. Consider accessibility for maintenance.
- Nosač za sigurno montažu: Use appropriate fasteners to securely attach the metal mounting bracket to a solid surface. Ensure the bracket is level.
- Pričvrstite detektor: Carefully mount the Vesda VLF-500-00 detector onto the secured bracket, ensuring it clicks firmly into place.
4.2 Pipe Network Installation
The detector operates by drawing air through a network of sampling pipes. The design and installation of this pipe network are paramount for accurate and early smoke detection.
- Dizajn: Follow the manufacturer's guidelines for pipe sizing, length, and sampling hole placement to ensure balanced air flow and optimal sensitivity.
- Montaža: Povežite sampling pipes to the detector's inlet port(s) and route them throughout the protected area. Seal all joints to prevent air leaks.
- Raskid: Ensure the pipe network is properly terminated and any unused ports are sealed.
4.3 Električne veze
All electrical wiring must conform to local and national electrical codes.
- Napajanje: Connect the detector to a stable 18-30 VDC power source. The nominal power consumption is 3.0W, increasing to 11.7W in alarm. Nominal current is 410mA, increasing to 490mA in alarm.
- Relejni izlazi: Connect the alarm and fault relays to your fire alarm control panel or building management system as required.
- Interface Cards (Optional): If using optional interface cards, follow their specific wiring instructions.
- uzemljenje: Ensure the detector is properly grounded to prevent electrical interference and ensure safety.
5. Rukovanje detektorom
Once installed and powered, the Vesda VLF-500-00 operates continuously to monitor the air quality in the protected environment.
5.1 Redoslijed uključivanja
Upon initial power-up, the detector will perform a self-diagnostic test. The display will show status indicators during this process. Allow a few minutes for the system to stabilize and enter normal monitoring mode.
5.2 Normalan rad
In normal operation, the detector continuously draws air through the sampling pipe network. The internal fan operates quietly, and the display will typically show a 'Normal' or 'Monitoring' status, along with current smoke levels if configured.
5.3 Alarmni uvjeti
The Vesda VLF-500-00 is designed to detect very early signs of smoke. When smoke levels exceed pre-set thresholds, the detector will activate alarms:
- Warning/Alert: Indicates a slight increase in smoke, prompting investigation.
- Alarm: Indicates a significant smoke presence, triggering connected fire alarm systems.
- vatra: Highest alarm level, indicating a confirmed fire condition.
The detector's display will show the specific alarm level, and corresponding relays will activate to notify the fire alarm control panel.
6. Održavanje
Regular maintenance ensures the long-term reliability and performance of your Vesda VLF-500-00 detector.
6.1 Routine Checks (Monthly)
