Automatic fire alarm (APS) (Fire alarm installation)
The APS includes subsystems:
- Fire alarm.
- Evacuation management.
- Water, foam or gas fire extinguishing.
- Control and access control (ACS)
- Smoke removal and ventilation control.
The task of MTA:
- Detection of any signs of ignition (gas, smoke or open fire) at the earliest stages.
- Transfer of an alarm signal to the console or guard post.
- Informing staff about the fire.
- Management of evacuation.
- Automatic unlocking of all turnstiles, gates, doors for free evacuation.
- Automatic return of elevators to the 1st floor and the opening of their doors.
- Automatic activation of smoke and fire extinguishing systems.
The principle of the APS: Having detected signs of ignition at the earliest stage, APS:
- Includes an alarm system (voice or light and sound) and evacuation control.
- Simultaneously transmits control signals to all other subsystems: access control, smoke removal, elevator control, fire extinguishing and forced ventilation systems.
Characteristics of SAM types
- Ways of notification depending on the type of premises:
- Sound (siren or toned spetssignal).
- Speech (broadcasting previously recorded text).
- Luminous: Blinking annunciators, signs "Exit".
- Separation of the object into warning zones.
- Feedback from the guard post.
- Centralized management of all building systems.
Purpose:
liquidation of a fire without damage to equipment at facilities with a large number of electrical equipment and high-tech equipment.
Operating principle:
immediately after automatic or manual start-up, the system fills the room with gas. By reducing the concentration of oxygen, this makes combustion impossible.
Destination:
the localization of smoke and gas, the release of evacuation routes from them, the preservation of human health and life.
Varieties
- Gravitational. When an alarm is triggered, the pneumatic actuator opens the dome of an antiaircraft lamp mounted on the roof or in the windows. The lantern draws smoke.
- Automatic. Draws on the fan by automatically turning on the fans
Organization of technical and administrative support Organization of quality control of work performance;
↓
Mobilization (departure of personnel to an object with special clothing, PPE, special tools, accommodation, meals)
↓
Stage 1 (preparatory work), the equipment is pre-installed (checked), the working documentation is reviewed, comments on equipment, correct installation, etc.
↓
Stage 2 (offline setup) Provision of temporary power supply, preparation for the inclusion of systems: checking CO and software functioning, setting up logical and temporal relationships of alarm systems, protection , blocking and control; checking the correctness of the passage of signals;
↓
Stage 3 (individual tests) constant voltage supply, system activation, software debugging, system operation check for individual testing of process equipment, correction hardware settings
↓
Stage 4 (comprehensive setup) providing interconnections, adjusting and adjusting the characteristics and parameters of individual devices and functional groups, testing electrical equipment; systems of control, control, automation; systems PAZ, together with the technological equipment "under load" within 72 hours
↓
Submission of a technical report (forms or passports for SI, lists of settings, settings, schematic diagrams with corrections, recommendations on the operation of systems) to the Customer
↓
Transmission of power supply systems, automation into operation Signing of acceptance certificates
