Pdf format

In accordance with SP 109.13330.2012 "Refrigerators" clause 5.29, in the premises of refrigerators, the project provides for a security alarm "Man in a cell".

Signal output is provided to the control room (room 26) with round-the-clock presence of personnel to the operator's console of the "ChK-10" type.

Work algorithm.

In the normal operating mode (the panic buttons are inactive), there are no signaling from the operator's addressable LEDs and no sound signaling on the operator's panel. The backlight of the most disturbing USO button operates in continuous mode.

When the alarm button is activated in the USO controller, a signal is generated to turn on the executive device in the form of a light board "Man in a cell" and an addressable alarm signal to turn on light and sound alarms on the operator's console.

If the connection between the USO and the control panel is not broken, then the button illumination starts blinking at a frequency of 0.5 Hz, and the signal LED of this USO on the operator's console will light up continuously. An audible alarm sounds.

In the absence of communication between the USO and the operator's console, the signal to turn on the CHSO light board is generated, but the blinking frequency of the button backlight becomes 2 Hz. The signal LED for this USO on the control panel induces a malfunction - it lights up in a pulsed mode (2 times per second). There is no audible alarm.

When the panic button is pressed again, its backlight switches to continuous mode, the corresponding addressable signaling LED on the operator's console and there are no sound alarms.

Safety instructions.

9. WARRANTY OBLIGATIONS

The manufacturer guarantees the conformity of the Product "Man in the Chamber" 9.1 to the requirements of the State Committee for Standardization of Statistics 63.00.00.000TU, provided that the consumer observes the conditions of transportation, storage and operation.

The issue of installing fire detectors in refrigeration chambers causes a lot of controversy among designers. Some equate freezers to production facilities with a wet process, referring to SP 5.13130.2009. According to the code of practice, such facilities may not be equipped with fire alarm systems.

On the other hand, an industrial one is a warehouse building in which service personnel are constantly located, powerful electrical equipment works. Inside there may be a wooden or cardboard container that creates a fire load (table 1 Appendix M, all the same SP).

If you turn to SP 109.1330.2012, you can find a paragraph that says about the mandatory installation of PI in rooms with a constant stay of people. This fully applies to refrigerated warehouses, especially to facilities with a large cargo turnover, which often operate around the clock.

The NPB 110 says the same. In any case, the protection of cold stores is the preferred option both from a safety point of view and from the point of view of possible questions from supervisory authorities.

Risk factors

A fire in a refrigerator can occur for various reasons:

• high flammability of polystyrene or polyurethane foam insulation;
• fire of wooden pallets or packaging materials;

It is impossible to install fire extinguishing systems in freezer warehouses. It is only possible to protect a business from possible losses associated with a fire by installing a PI.

Subtleties of choosing PI for refrigerated warehouses

There are a number of technical nuances that are known only to design engineers. Knowledge of these subtleties helps to make the right choice:

1. In industrial refrigerators, temperatures can drop to -40 ° C. Under these conditions, the electrical components of a passive fire alarm are ineffective. The equipment may simply not work at the right time. In some countries, it is even allowed not to install detectors in rooms with temperatures below 0 ° C.
2. obstruct the movement of air currents under the ceiling. This often leads to a delayed actuation of the fire alarm, making it impossible for the smoke extractors to work.

Modern technical solutions - VESDA aspiration system

Active smoke detection aspiration systems are optimal for cold storage. The principle of operation of the system is based on constant monitoring of the quality composition of the air in the protected area. The device with a specified time interval takes samples, analyzes them and, based on the data obtained, sends a signal to the central console.

This allows you to detect smoke at the initial stage, minimize contamination of products, equipment and other property with combustion products.

One of the most advanced today is the VESDA smoke aspiration system. It works effectively at temperatures down to -40 ° C, and has several advantageous structural differences:

• sampling is carried out in several rooms through a pipe system with multiple holes;
• air analysis is carried out in a smoke detector located outside the warehouse (in the zone of positive temperatures). The detector is located in an easily accessible room, which allows remote monitoring in remote areas;
• the sensitivity threshold of the device can be adjusted depending on the degree of fire spread;
• the flexibility of the system allows for reliable protection of freezing warehouses of any configuration. At the same time, a pipe system with an area of ​​up to 2000 m 2 can be connected to one detector;
• analysis of the warehouse at the design stage allows you to choose the most suitable fire protection system. The specialist assesses the risks, determines the possible sources of smoke, the direction of the air flows in the building, and takes into account the specifics of the stored products.

Another important advantage of VESDA solutions is the consideration of warehouse operating parameters. The equipment can be integrated into existing moisture and temperature control systems, automatic product handling and storage systems.
