The installation of a fire alarm system cannot provide a 100% guarantee of complete safety. You need to make sure that the system is under round the clock control of professionals. Timely maintenance of public address systems is the basis for uninterrupted functioning of fire alarm systems, which means ensuring human health and life and preservation of material assets.
The main task of such servicing is to maintain its full functionality under any conditions and regardless of external factors. The main condition of servicing is regularity of preventive measures; it will help to eliminate unforeseen emergencies and failure of alarm systems. Each element of the system is equipped with a complex mechanism, so it is extremely important to maintain all components of the system in proper working order as it directly affects the level of fire safety.
Fire alarm servicing is a licensed type of activity and cannot be performed by random people. The complex of technical preventive and repair work can be performed only by appropriately trained and experienced professionals.
Maintenance of the systems consists of the following main points:
- Regular monitoring of electrical appliances functionality.
- Timely detection and repair of breakages.
- Calibrating schedule control.
- Measures to minimize faulty actuations of the system.
A service contract is concluded between the initiating company and the company providing such services for complex maintenance of alarm systems. The latter companies may include:
- companies-manufacturers of devices separately or systems in general;
- organizations involved in installation work and which have installed the system;
- certified and licensed operating companies.
All works performed by any of the above listed organizations are strictly regulated on the basis of specialized standards, laws and specially developed safety instructions. The main information of the service contract is frequency of certain activities performing. Any operation performed by an authorized specialist is necessarily recorded in a special journal.
According to the period of work execution all works are divided into the following groups:
- Daily.
- Monthly.
- Complex measurement works.
Daily routine maintenance is carried out directly by the employees of operational services of the enterprise and consists in a visual inspection of the main instruments. They include peripheral sensors, control panels, power and data transmission systems, emergency power system. The integrity of all seals, the functionality of light indicators, knife switches and switches are checked.
Complex of monthly measures as per procedures includes checking of the main and standby power supply system, functionality of all mechanisms responsible for switching of power supply between all sources. The diagnostics of each individual device, namely, control and transmitting devices, sensors, loudspeakers and sirens of the system is made. It is necessary to measure the loops, in case of zoning all devices within the zones and boundaries are tested.
All preventive works directly depend on the characteristics and configuration of the fire alarm system, but more rarely than once a quarter. The work on measuring of insulation parameters is carried out by specialists once every three years.
Measuring work provides determination of operating conditions of any device. The startups of testing activation, which show the level of efficiency, are carried out.
When concluding a service contract, the order of work is specified in accordance with the Procedure No. 1 or Procedure No. 2 for scheduled, unscheduled and corrective maintenance.
Procedure No. 1 includes the following works:
- visual inspection, check of functionality of each element and the general system;
- elimination of detected breakages and malfunctions;
- adjustment of the devices;
- cleaning of fire detectors
- checking of the capacitive standby power supply;
Procedure No. 2 contains a list of works under Procedure No. 1, as well as all measures of a schedule preventive nature, testing of technical means for resistance to interferences. The frequency of work is at least once a quarter.
If there are any precedents of repeated false alarms through the fault of the system, urgent unscheduled works are carried out.
Concluding a contract with a company that renders services for maintenance of fire alarm systems it is important to choose a reliable organization. Arguments in favor of choosing a firm can be the following:
- Mandatory licensing of services rendered.
- Timeliness and reliability.
- 24-hour customer accessibility.
- Rapid response to extraordinary situations.
- Level of professionalism of the team of specialists.
- Flexible and fair pricing policy.
- Availability of an arsenal of necessary equipment.
