Carlo Gavazzi has provided a Dupline building automation system to the North London Assembly Hall for Jehovah’s Witnesses.
The objective was to provide a system to open and close roller shutters fitted to windows and doors, and to control entry and exits gates from a central location. Distributed I/O modules were fitted at each point where control was required and then connected to a central controller over the Dupline two-wire bus. Although a new data cable was installed, the product made it possible to use a variety of existing cables, thus keeping installation cost to a minimum, according to the product firm.
What they say
“Security is a major issue in any environment, especially when a building is not occupied for long periods of time, so we were delighted that the Dupline system only took two weeks to install,” said Ken Adamson, electrical installer, for the North London Assembly Hall. “The Dupline system is very easy to programme, field devices are configured with just a simple hand held device,” Ken added. “It has dramatically reduced the time taken to open-up and lock-down the building as it can now be controlled from one central panel in the security office – instead of 30 minutes it takes two!”
The Dupline concept is suitable, it is claimed, for future expansion or upgrade, as the wiring is already in place, it’s just a question of adding more I/O modules. “One possible upgrade would be to add a Dupline Master Channel Generator with a built in GSM modem, in this way full monitoring and control could be achieved remotely by mobile phone,” said Kevin Sheldrake, Product Marketing Manager, Dupline & Sensors, Carlo Gavazzi.
