Testing & Commissioning Fire Protection System

Before detail explanation given on how to conduct T&C for Fire Protection System, let introduce overall concept of installation adopted.

The system consist of 4 CO2 Panel in which every of them have the followings.

1. Heat detector
2. Smoke detector
3. Fire curtain
4. CO2 gas cylinder

Procedure of Testing shall be as follow.

1. Check whether installation is completed as per drawing or not.
2. Check physical installation whether any defect or irregularity observed.
3. Start with Lamp Check for panel - To ensure all indicators are functioning well.
4. Check Battery and Charger condition.
5. Test Heat detector - Apply heat ( normally using lighter) to heat detector. Check whether detector triggered or not. If detector triggered, signal will be sent to CO2 panel and indicator light will lights up at CO2 panel. Bell will start ringing.
6. Test Smoke detector - Apply smoke tester by spraying smoke to detector. Second alarm will comes in and CO2 panel indicator will indicates light.
7. At this moment, fire curtain will drop down.
8. After 30 Seconds, CO2 gas will be released from CO2 cylinders. Gas will be flooding room area and  to cease the fire.
9. Reset alarm after attending the fault.

Manual Key Switch

Solenoid valve

Note and Precaution.

1. Solenoid valve connection at CO2 cylinder shall be isolated to avoid actual release of the gas during activation. Unless, actual testing is required and spelt out in B.O.Q.
2. However, in order to check signal to solenoid valve, a voltage test can carry out. A 24V signal will be recorded when signal from CO2 panel sent to solenoid valve to release CO2 gas.

Installation of Underfloor Trunking

Underfloor trunking is commonly used for the following services.

1. Telephone services
2. Network/Data cable
3. Wiring for Switch Socket Outlet.

The main reason for using underfloor trunking is to suite location of the final point which is away from wall. In normal situation, socket outlet is located on the wall. The cabling comes from ceiling coming down through concealed/exposed conduit and terminated on S.S.O point.

Some of the pictures depict underfloor trunking installation can be referred below.

1. PVC underfloor trunking was installed between 2 layers of BRC.
2. Foams were used as a temporary basis to provide space for underfloor service box during casting of the floor slab

Note: Underfloor pipe shall be properly secured to BRC before concreting work commenced. This to ensure alignment and position of the pipe is not misplace during floor concreting.
