Multi Zone Smoke Ventilation System – Southend-on-Sea

Location: 3-5 High Street, Southend-on-Sea

Date: September 2016

Rocburn were chosen to supply the smoke ventilation equipment to be installed as part of renovation works for 3-5 High Street, Southend-on-Sea, Essex. This was to convert offices into residential properties located in the town centre.

Smoke Ventilation Equipment Supplied:

• 1 x 10 zone 20amp Multi Zone smoke vent control panel
• 4 x EN12101-2 tested AOV Roof hatches
• 6 x 1mtr Square EN1366-2 Fire rated dampers and grilles – painted matt black louvers & white grilles
• 8 x Fireman’s Override Switches

Project Overview

This job consisted of 1 stair core ventilated by a 1mtr square smoke ventilation roof hatch, with left and right hand lobbies on the 1st 2nd and 3rd floors (plus a dedicated penthouse lobby vent). Each lobby had a damper and grille fitted to ventilate smoke into an assigned smoke shaft.

The control panel was wired back to an addressable fire alarm, which would trigger on smoke to open the damper on the fire floor along with the related roof hatch. This automatically cleared the communal escape routes of smoke.

The smoke ventilation equipment was specified in accordance with Approved Document B.
