A fire alarm system is only useful if it works on the day of a fire. Dust builds up in detectors, batteries age, cables get damaged during renovations and panels log faults that nobody reads. An annual maintenance contract (AMC) keeps the system tested, repaired and documented, which also matters when you renew your fire NOC or face an insurance or client audit.
Why regular maintenance is required
The National Building Code of India (NBC 2016, Part 4: Fire and Life Safety) and IS 2189, the Indian Standard code of practice for fire detection and alarm systems, expect installed systems to be regularly inspected, tested and maintained. Fire authorities such as Delhi Fire Service check that fire safety systems are in working order during inspections, and maintenance records help show that.
How often should the system be serviced?
Most commercial and industrial buildings in Delhi NCR choose quarterly visits. High-risk sites such as hospitals, data centres, malls and chemical plants often choose monthly visits. Whatever the frequency, every device in the system should be tested at least once a year.
AMC checklist: what each visit should cover
Control panel
- Check the panel for faults, disablements and the event log
- Test standby batteries and the charger, and replace batteries showing reduced capacity
- Confirm zone and loop labels match the building layout
Detectors and call points
- Functionally test smoke detectors with test aerosol and heat detectors with a heat tester
- Clean or replace dirty detectors, especially in dusty factory areas
- Test manual call points
- Test beam detectors and check their alignment
Alarms and interfaces
- Test hooters, sounders and strobes in every zone
- Test interfaces: HVAC shutdown, lift recall, access control door release, fire damper and suppression system signals
- Check the public address system if it is linked to the fire alarm
Cabling and records
- Check for earth faults, open circuits and damaged cable or conduit
- Update the logbook and give a signed service report after every visit
- List defects with a clear quote and timeline for repairs
Comprehensive vs non-comprehensive AMC
| Type | What is included | Best for |
|---|---|---|
| Non-comprehensive | Visits, testing, cleaning and labour. Spare parts are charged separately | Newer systems with few failures |
| Comprehensive | Visits, labour and most spare parts within the contract price | Older systems, or sites that want a fixed yearly cost |
Batteries, consumables and damage from misuse are often excluded even in comprehensive contracts, so read the exclusions list.
Red flags in an AMC provider
- Visits that only check the panel display, without testing devices
- No written service report or logbook entries
- No 24×7 breakdown contact or response time commitment
- Technicians unfamiliar with your panel brand, such as Edwards or addressable systems
A good AMC can also cover fire extinguishers, hydrant systems, sprinklers and gas detection under one contract, with one report for your fire NOC file.
Frequently asked questions
Can a different company maintain a system someone else installed?
Yes. A competent contractor starts with a survey of the existing system and lists any defects before the AMC begins.
Does an AMC include fire NOC paperwork?
Maintenance reports and test records support your NOC renewal. Some providers also help prepare the documents. Ask what is included.
