PART 2 PRODUCTS

2.1 SYSTEM DESCRIPTION

System shall consist of a detector assembly housing an integral aspiration fan, filter, laser based detection chamber and control, output and supervision circuitry.

System shall consist of a piping or tubing distribution network that runs from the detector assembly(s) to the protected area(s) and is supported by calculations from a computer-based design modeling tool.

System shall consist of sampling points placed on the piping or tubing network within the airstream of return air or transfer grilles and, where specified, make up air ducts at spacing as specified herein and by Manufacturer's guidelines.

For open area coverage system shall consist of sampling points placed on the piping or tubing network at locations where smoke detectors are required by all applicable codes and Owner's Standards as indicated in this Specification.

In operation, the aspiration fan in the detector assembly draws air from sampling points in the piping or tubing distribution network back to the detector assembly where it is analyzed for fire products.

System shall include configurable alarm and trouble relay outputs for interface to other systems where required.

The system shall communicate digitally to the main fire alarm system panel. All digital parameters of the VESDA panel such as % obscuration, % filter dirty, etc, shall be communicated digitally to the panel. Systems that integrate to the main fire alarm system via a series of addressible dry contact modules to communicate alarm, trouble, supervisory, and other conditions are not acceptable. The connection between the VESDA panel and the fire alarm panel must be a digital connection via a digital signalling line circuit.

2.1.1 Design Requirements

Specification subparagraph text.

2.1.2 Performance Requirements

System shall be complete in all ways. It shall include all engineering, and electrical installation, all detection and control equipment, auxiliary devices and controls, alarm interface, functional checkout and testing, training and all other operations necessary for a functional, UL listed and FM Approved system.

System design, installation, commissioning and testing shall be in accordance with this Specification, the Manufacturer's guidelines and per all applicable codes and requirements of the local Authorities Having Jurisdiction (AHJ).

All Air Sampling Smoke Detection devices and associated components shall be new, standard products or the manufacturer's latest design and suitable to perform the functions intended.

Air sampling network shall be designed and installed to monitor the total
