Grading/ Installation
Grading for installation of detector and alarm
| Factor | Grading criteria | Grade |
| Wiring | Neatly run with supporting interval as per manufacturer’s instruction.
Special checking for concealed places. For e.g. above false ceiling it should be fastened to the structure – should not be lying on the panels. Preferably protected by sleeve when cables pass through walls. Joint should be minimum and protected in a junction box. |
Yes:5
No:1 |
| Mounting | Should be securely mounted. Else vibration from structure may spoil a sensitive instrument.
Proper alignment (esp. for flame detector). Else its function is disabled. |
Yes:5
No:1 |
| Test | The system is checked through the following test(s) as required by authority:
Three-second response test for manual call point. Battery removal test. Simulated mains failure test Sounder circuit fault test Detector circuit fault test Detector removal test Note: testing should be carried out at the remotest part with closed door condition. Special care for acoustic partitioning should be taken. After test the system should be recalibrated and made ready for use. |

Grading for installation of fire hydrant and hose
|
Factor |
Grading criteria |
Grade |
||
| Hydrant and accessories | ||||
| Storage | Parts stored in a clean, dry and safe place. It prevents loss, deterioration, damage of pipe, pipe threads fittings, couplings etc. | Yes:5
No:1 |
||
| Install | Mounting height of hydrant and breeching inlet should be strictly maintained.
Installation should be secure and safe. Special consideration should be given to the potential damage sources: External pipe : mechanical damage, falling debris. Underground pipe: vehicular traffic, pressure & thrust from ground. Internal pipe : gas, electric pipeline, structural vibration Connections and position of valves as per specification. Risers anchored securely before any pressure or flow test is performed. Made operable immediately after completion and testing. That protects the building under construction. |

| Testing | Element | Test name | Elements checked | Yes:5
No:1
|
| Fire hydrant | Wet test | Condition of pit, frames, cover, surface paving around edge of frames. | ||
| Flushing | Flow and pressure of outlet connection. | |||
| Dry & wet riser | Visual inspection | General condition, earthing, venting requirement | ||
| Hydrostatic test | Leakage, blockage under operating pressure. | |||
| Static pressure test | Leakage esp. at joint or landing valves. | |||
| Flow test | Errors like undue pressure loss in riser | |||
| Note: For taller buildings, each zone of wet-rising main to be tested separately. After testing the pipes should be reset and made ready for immediate use. | ||||
| Fire hose | ||||
| Base work | Reel brackets are fixed firmly else hose may not be used properly.
Stored in a cool, dry place (BS ISO 2230). |
Yes:5
No:1 |
||
| Commissioning | Before using, the hose is flushed out to remove any harmful matter especially for automatic hose reels.
Flush out test: the tubing is run out to remove any kink or knot and the valves and nozzles are fully operational. After the flush out test, the hose is drained and returned to the drum and all the valves are closed. Hydrostatic test as per codes (e.g. BS 1402 Rubber and plastics hoses and hose assemblies). |

Grading for installation of sprinkler system
|
Factor |
Grading criteria |
Grade |
|
| Mounting | Exactly according to the design approved by the authority and instructed by manufacturer. The general guideline as follows (NCCER, 2007, NFPA 13): | Yes:5
No:1 |
|
| Type | Mounting position | ||
| Spray (SP) | Horizontally with deflector towards window / wall | ||
| Upright spray (SU) | Horizontally with deflector away from window/ wall | ||
| Pendent sidewall (WP) | Hung like pendent and oriented to window / wall | ||
| Conventional (CUP) | Only beneath the roof overhangs. | ||
| Supports | Before fixing the adequate strength of supporting elements are checked.
Cross checked if supports hinder sprinkler head. Adoption of approved fastener and fixing method. The design may need to undergo a verification test with appropriate load without shock for a min period of 30 sec. |
Yes:5
No:1 |
|
| Supply network | The whole supply network (pump, piping, valves, tank etc) constructed / installed as per approved design.
Special attention to be given for alignment of piping, installation of valves. Often the gasket, washer or straps for locking are found omitted due to carelessness. Before putting into service the whole system should be checked and approved by the competent person. |
Yes:5
No:1 |

Grading for installation of portable extinguisher
|
Factor |
Grading criteria |
Grade |
| Mounting | Small (≤ 4 Kg): Hung on wall with hanger or bracket such that the handle is about 1.5m from floor.
Hangers should be securely fixed. Heavier (≥ 4 Kg): Carrying handle should be about 1m from floor. The arrangement should be such that the person carrying it should not be hurt. Parts should be attached as per manufacturer’s instruction. |
Yes: 5
No: 1 |
| Protection | Accessible yet protected from misuse or theft is achieved by:
In vandal proof zone: unlocked cabinets or free standing on floor or shelves. Else: locked cabinets with glass fronted receptacles to hold the key. |
Yes: 5
No: 1 |
Grading for installation of fire door
| Factor | Grading criteria | Grade |
| Fire door | ||
| Storage & handling | Delivery should be planned so as to reduce the storage time and also installed as late as possible. It prevents damage from subsequent construction activities.
Protected from direct sun, excessive moisture and corrosive or staining material. Leaves are laid flat on bearers to keep them away from ground contact. A protective wrapping is beneficial. |
Yes:5
No:1 |
| Fixing | Exactly same as of tested prototype i.e. as / manufacturer’s instruction.
Door frames installed during wall construction should be thoroughly grouted in cavity as deep as possible with corrosion proof anchor. Screws for attachment should be driven properly, not hammered or placed in other position. Latch / bolts at proper height and with adequate clearance for easy operation. |
Yes:5
No:1 |
| Checking | Min closing force maintained as per width.
Gaps (8mm at bottom and 3mm at other sides) may require seals for adjustment on both sides. No over-mortising is recommended. Care taken to avoid any mismatch of components, interchange of components of different doors, alteration of door swing etc. |
