SCOPELIFE SAFETY / SMOKE CONTROLICS / SC-02

The work

Smoke control and AOV maintenance, testing and recovery.

Smoke control depends on detection, control logic, power, actuators and mechanical plant. A healthy indication at the control panel does not prove that every part has operated.

PPM visits check the agreed controls, actuators, fans, dampers, power supplies, overrides, indications and interfaces.

Approach

From the reported fault to a tested conclusion.

The exact test plan depends on the system, its condition and the effect of taking equipment out of service. These are the usual stages for this type of work.

Confirm the intended strategy

Review the smoke control sequence, zones, overrides, interfaces and available drawings.

Follow each command

Trace the input through control logic, power, field wiring and feedback indications.

Verify physical operation

Observe actuators, vents, dampers and fans, then record where the sequence does not complete.

What ICS can investigate

Check the complete operating sequence.

+Control panels and local controllers
+Detection and override inputs
+Actuators, dampers, fans and feedback signals
+Power supplies and changeover arrangements
+Interfaces with fire alarm and building controls

Outputs

Test results, findings and required work.

The report format and level of detail are agreed before the work starts.
