Frequently Asked Questions
What is the detection actually protecting?
What sits underneath the pipe.
Electrical rooms beside risers.
Offices below ceiling void pipework.
Data cabling under raised floors.
The pipe itself is rarely the asset at risk.
That decides sensor placement and response speed.
Spot sensors or sensing cable?
Defined points against continuous coverage.
Spot sensors watch low points and trays.
Cable detects anywhere along its run.
Better cable systems report distance to the leak.
That turns a search into a walk.
Most installations use both.
Where do leaks actually occur?
At joints, valves, pumps and strainers.
Anywhere that has been opened for maintenance.
Mid-pipe failures are comparatively rare.
Covering runs while missing plant covers the wrong thing.
Walk the system and list the connections.
Concentrate sensing there.
Should detection close a valve automatically?
It depends what stopping the system costs.
Above a server room, isolating fast is clearly right.
On critical heating it creates its own risk.
Alarm-only with a manual decision is sometimes better.
The choice belongs to a written policy.
Decide it before commissioning, not during an incident.
What causes false alarms?
Condensation, most of the time.
Cold pipework sweats and drips.
That looks identical to a small leak.
Sensors near cold surfaces trip repeatedly.
Repeated false alarms end with systems disabled.
Site sensors away from cold pipework.
Where should sensors go in a plant room?
At the lowest points water will reach.
Floor level near pumps and strainers.
In drip trays beneath equipment.
Near any drain that could back up.
Water follows floor falls, not the plan.
Check the actual floor levels.
What should the alarm reach?
Somebody who can act, at any hour.
A panel in an empty plant room helps nobody.
Integration with the building system is normal.
Out-of-hours routing needs defining.
Test the whole path at commissioning.
An unrouted alarm is decoration.
