Design and Installation
Design
Sunfish's design team have many years experience of fire alarm design in a wide range of buildings and applications. All of our nominated designers have attended the British Fire Protection Systems Association training course in Fire Detection Design and are fully conversant with the requirements of BS5839-1:2002 and BS5839-6:2004.
Our design processes are in accordance with the requirements of SP203 and consider the appropriate standards and regulatory requirements of other interested parties including local building control authorities, fire brigade officers and insurers.
Our designs also consider potential false alarm issues and incorporate measures to reduce disruption following system commissioning.
Throughout the installation, commissioning and handover process the original design is verified in order that the completed system is fit for purpose.
Installation
All fire alarm installations are installed in fire rated cable and in accordance with IEE Wiring Regulations BS7671:2001.
We are experienced in working in a wide range of environments including new build construction sites, large office complexes, factories, hospitals, care homes and HMOs.
| | Design Facts - Did you know?
To ensure complete coverage, spacings between detectors should be reduced to 10.0m between smoke detectors and 7.0m between heat detectors.

| Design Facts - Did you know?
For obstructions of less than 250mm Y should be at least 2 x Z
Beams and Other Similar Ceiling Obstructions
Fire detectors should be mounted at least 500mm away from walls or ceiling obstructions greater than 250mm deep and at least twice the depth of obstructions less than 250mm deep. They should also be mounted at least 1m away from any forced air inlet. Where the obstruction is greater than 10% of the height of an area it should be considered as a wall. Similarly a floor mounted obstruction (such as racking) should be considered a wall if it comes to within 300mm of the height of the detector.
