Smoke Detection

One system that offers a good guarantee for the early detection of a fire risk is automatic site protection through smoke detection. The techniques available identify the measurable products of the reaction material or the secondary effects of the energy reaction.

The most commonly used techniques are:

  • Smoke detection: smoke detectors react to volatile particles and aerosols produced by combustion.
  • Heat detection: heat detectors react to an increase in ambient temperature.
  • Flame detection: the optical sensors used convert the optical signal (electromagnetic radiation) emitted by flames into an electrical signal.

In order to ensure their effectiveness, it is essential that the checks required by the standards, which detail all the activities and maintenance schedules, be performed by specialised personnel.

Maintenance phases and frequency

Phase Frequency Situation
Initial inspection - Assumption
(responsible company) 		Occasional Before delivery of a new or modified system or when assuming the maintenance of a system
Monitoring
(internal) 		Continuous According to the scheduled maintenance plan dal responsabile del sistema
Routine maintenance
(responsible company) 		At least every 6 months According to the scheduled maintenance plan
Extraordinary maintenance
(responsible company) 		Occasional According to need for major repairs
General system check
(responsible company) 		At least every 12 years According to regulations and laws, depending on the equipment used or the instructions of the equipment manufacturers

Documentation to be acquired prior to starting maintenance activities

  • User and maintenance manual;
  • As-built designs and documentation of the system;
  • For ASD systems, calculation of system sizing;
  • Manufacturers' test procedure;
  • Test equipment
  • Electronic instruments suitable for the tests to be performed.

Initial inspection

To be performed by the Maintenance Technician

Preliminary Inspection
  • Verification that the system corresponds to the executive plan; Installation in conformity with CEI 64-8;
  • Visual inspection of the system;
  • Verification of the earthing of the system.
Functional Check
  • Verification that the system logics correspond to the project requirements;
  • In the presence of other interconnected systems (active or passive protection or technological systems), check that the system logics are consistent with the project requirements.

Monitoring

To be completed by the Assigned personnel

What?
  • Checking, at least monthly, the spare parts or replenish stock
  • Visual inspection
  • Checking the status messages on the control unit
When?
  • Daily, weekly, monthly depending on the type of check to be carried out and the size of the system
Increase frequency in the case of:
  • Installations in very dusty environments
  • Installations in environments with frequent temperature changes
  • Installations in environments with high humidity or presence of vapours
  • Specific requirements of the manufacturer or designer

Periodic inspection

To be performed by the Maintenance Technician

What?
  • Check that the initial inspection documents are on hand;
  • Check that no actions have been taken or structural changes made in the protected environment.
How?
Conventional systems:
-
100% testing of devices
Analogue Systems:
0-6 years
Over a period of 12 months a functional check must be performed on 50% of all devices in all detection zones (twice per year)
7-12 years
Over a period of 12 months a functional check must be performed on 100% of all devices (twice per year)
beyond 12 years
After 12 years the system must undergo a general review

General system check

To be performed by the Maintenance Technician

When?
  • At least once every 12 years.
What?
  • Verification of the availability of spare parts;
  • Verification that the system has not changed (if substantial modifications have been made, the technical documentation must be acquired in the new as-built configuration).
How?
  • Factory overhaul;
  • Replacement with new detectors;
  • Execution of physical test.
