Method Statement for Fire Suppression System Installation Testing & Commissioning

Required Tools/Equipment

• Multimeter
• Detector Testing Tool
• Hilti Machine
• Drill Machine
• Pull string
• Step Ladders
• Mobile Scaffold

Preparation Work Before Installation

• With the aid of computer software program design the system and prepare isometric drawing.
• Prepare layout drawing of piping network system and mechanical equipment of SINORIX1230 System.
• Prepare drawings of detection system.
• Obtain approval of the concerned authorities for the drawing.
• Arrange inspection of the pipe, fittings and installation accessories and obtain approval prior to the commencement of installation works.

Fire Suppression System Installation Procedure
Piping Work

• Use schedule 40 pipes with 3000 PSI fittings. Install pipe and fitting in strict accordance with the approved drawing.
• Piping between cylinder and nozzles must be through shortest route possible.
• Any deviation in the routing or number of fittings must be approved by the Design Engineer prior to the installation.
• All piping shall be earth bonded. Piping must be reamed free of burrs and ridges after cutting or threading.
• Teflon tape only need to be applied on pipe joints. Tape should be applied on male thread only.
• All pipe hangers must conform to general industry standard.
• For reducing pipe size use only concentric bell reducers.
• Before fixing discharge nozzles blow the system piping free of debris.
• Install nozzles, ensure that correct nozzles types part numbers and orifice sizes are installed in the proper locations.
• Ensure piping and nozzles do not interface with objects in the hazard area.
• Install SINORIX1230 cylinder at the location shown in the drawing observing the safety requirements while handling the SINORIX1230 cylinder.
• Secure the cylinder to a solid structure.
• Connect the pipe system to the cylinder.

Installation of Fire Detection System

• Arrange detection system material inspection and obtain necessary approval.
• Install the control panel and devices as per the approved drawing layout.
• Test the cabling for open, short circuits prior to connecting to devices.
• Terminate the cabling and conduct pre commissioning tests on the system.
