LAW AND REGULATIONS : FIRE FIGHTING INSTALLATIONS

COMPONENTS

Fire alarm panel

Manual break glass

Alarm bell

FIRE ALARM SYSTEM : MANUAL ALARM

AN ALARM PANEL: monitors the state of all parts (zones) of theinstallation.

POINT DETECTORS: individual heat or smoke detection unitswhich respond to an irregular situation in the immediate vicinity

LINE DETECTORS: a continuous type of detection comprising apair of conducting cables separated by low temperature meltinginsulation to permit a short circuit alarm when the cable contact.

POWER SUPPLY: These should have primary (normal electricity)and secondary (battery) power supplies.

Fire Alarm System : FIRE FIGHTING INSTALLATIONS

Smoke Detector : FIRE FIGHTING INSTALLATIONS

Fire alarm system isfunctioning as a componentswhich give warning sign tooccupants in a building if it isburning.

It normally, installed withdetector.

There is 2 type of detector, passive (Manual break glass) and active (Smoke detector, heat detector, light detector).

‘KELUAR’ sign and emergency light

Flashing lights

HOSE REEL SYSTEM : WET RISER

Pressurised using 1 unit of electrical pumpset as duty pump & 1 unit diesel engine pumpset as standby

Designed to operate an automatic mode (Pressure switch) & manual mode (manual starting from the pumpsets control panel)

Standard coil length 30m, 36m or 100m.

Specification :-Working Pressure : 220Psi (15 Bar)Minimum Burst Pressure : 696Psi (48 Bar)Test Pressure : 250Psi

HOSE REEL SYSTEM: FIRE FIGHTING INSTALLATIONS

TYPICAL HOSE REEL: FIRE FIGHTING INSTALLATIONS

General purpose synthetic delivery hose. Suitable for industrial and rural fire brigades as well as static building protection.

General industrial, commercial and civil engineering applications including waterauthorities where a high burst performance hose is not necessary

Lightweight and flexible Heat and cold resistant Anti rot and anti-twist

Synthetic Delivery Nose : FIRE FIGHTING INSTALLATIONS

Branch pipes provide an adjustable nozzle to allow the curtain of water to be altered from a narrow spray to a wide spray.

Nozzles provide a fixed jet of water. The basic branch pipe according to BS336 has an 21/2" inlet male instantaneous and outlet threaded 11/3" BSP male for either a plain jet or a branchpipe adjustable nozzle.

The branch pipe is controlled from SHUT-OFF through JET and SPRAY to wide angle CURTAIN by rotating the annular sleeve.

Branch Pipe and Nozzle : FIRE FIGHTING INSTALLATIONS
