The construction contract was awarded to Jarvis with their M&E division, E7 Building Services. Silver Group have a strong, long standing relationship with Jarvis and E7BS having already completed many other projects with them.
Due to the different uses and main access points of the ground floor compared to the upper residential floors, it was necessary to have two separate fire alarm systems and yet still be linked. In addition, the residential fire detection system had to be linked to the buildings sprinkler system that had been installed by the contractor. And of course the detectors and fire alarm panel must be correctly linked to the smoke ventilation system.
The Silver Group Solution
With such a large project and nature of the construction, Silver Group split the installation into separate phases. The first being installing all the necessary wiring for fire alarm and vent systems during the early stages of construction. Then all the devices are installed along with the galvanised metal roof mounted vents. Then finally at the latter stages, full commissioning, testing and certification.
The ground floor L2 fire protection system comprising of 21x smoke detectors and 3x heat detectors including sounder bases, as well as 8 x manual call points and of course the addressable fire alarm panel and interface units.
Across the upper residential floors, the L5 fire alarm system comprises of 44x smoke detectors, 2x heat detectors, 40x interface units (including those to the sprinkler system) and a 40 zone alarm panel.
The smoke ventilation system comprises of 12x window actuators, 6x smoke shaft door actuators, 13x controllers, 1x Modular Smoke Control System, 38x Photo-electric detectors, and 5x smoke ventilators (roof mounted) and 25x Manual call points.
During the commissioning, a custom cause and effect programme was written for the multi-level system with integration to the sprinkler system. Final testing, certification and hand over to the client is due during January 2019.
