Wet-System Fire AMC Scope in Dubai
A wet-system fire AMC covers the pressurised water systems that fight a fire: the fire pump set (electric and any diesel pump, jockey pump, controllers and auto-start sequence), the sprinkler network (control valves, flow switches, gauges and heads), hose reels and internal/external hydrants and landing valves, and the connecting valves, gauges and pipework that keep the whole system charged. It excludes detection, which sits under a separate fire alarm scope — the two together form a complete fire systems AMC.

The pump room: where a wet system lives or dies
Every sprinkler head and hydrant on site is dead metal without pressurised water behind it, and that pressure comes from the pump room. A wet-system AMC starts here — the auto-start sequence, the pressures, the jockey pump that holds standby pressure, and the controllers that must bring the pump online the instant demand drops the line.
- Fire pump auto-start sequence proven against pressure drop.
- Jockey pump holding standby pressure without hunting.
- Electric and any diesel pump exercised under flow.
- Controllers, alarms and changeover checked.
- Suction, discharge and relief-valve condition verified.
Sprinklers, hydrants and hose reels
Downstream of the pump, the wet-system scope follows the water: sprinkler control valves and flow switches that prove flow, hydrants and landing valves for the fire service, and hose reels for first-response use. Each has a physical check — a valve that won't open or a flow switch that won't signal is a silent failure until it is tested.
- Sprinkler control valves, flow switches and gauges tested.
- Sprinkler heads checked for corrosion, paint and obstruction.
- Internal and external hydrants and landing valves proven.
- Hose reels pressure-checked and free-running.
- Zone and isolation valves confirmed in the correct position.
Where the wet-system scope stops
Knowing what a wet-system AMC does not cover matters as much as what it does. Detection — panel, detectors, call points — is a separate alarm scope. Gas suppression for server rooms is a clean-agent scope. Drawing these lines is what stops a defect falling in a gap; most buildings combine wet, detection and gas under one fire systems AMC for exactly that reason.
- Detection and warning sit under a separate fire alarm AMC.
- Gas and clean-agent suppression are a distinct scope.
- Fire extinguisher servicing is often listed as its own line.
- Base-building vs tenant boundaries must be defined in the contract.
- A combined fire systems AMC closes the gaps between all scopes.

Frequently Asked Questions
Answers for facility managers checking that a fire fighting contract reaches every wet-system component.
What does a wet-system fire AMC cover?
The pressurised water fire fighting systems: the fire pump set (electric and any diesel pump, jockey pump, controllers, auto-start), the sprinkler network (valves, flow switches, gauges, heads), hose reels, hydrants and landing valves, and the connecting valves and pipework. It does not cover detection or gas suppression.
Is the fire pump the most important part of the scope?
It is the critical part, because every sprinkler head and hydrant depends on the pressure the pump provides. A wet-system AMC prioritises proving the pump's auto-start sequence, pressures and jockey pump, since a failure there disables the entire distribution downstream.
Does a wet-system AMC include the fire alarm?
No. Detection and warning — panel, detectors, call points, sounders — sit under a separate fire alarm AMC. Wet-system cover is the suppression half; most buildings combine both under one fire systems AMC so nothing falls between the two scopes.
Are hose reels and hydrants part of the wet-system scope?
Yes. Hose reels are pressure-checked and confirmed free-running, and internal and external hydrants and landing valves are proven operable for first-response and fire-service use, alongside the sprinkler network and pump.
How does QSERV test a wet system without flooding the building?
Testing uses test valves, drain connections and flow-metering rather than discharging through heads. Pumps are exercised under controlled flow, and valves and switches are proven at their test points, so the system is verified without soaking the premises.
Do you subcontract the pump or sprinkler work?
No. QSERV maintains the full wet system — pump, sprinklers, hydrants and hose reels — with its own in-house teams as a DCD-approved contractor, so one accountable party owns every component in the scope.
