Fire safety requires special attention, because it is designed to save lives and preserve property. Therefore, mankind at all times invented ways to warn about a fire. This is most relevant in places where the risk of fire is especially high.

In fire extinguishing and fire alarm systems, manual fire detector IP 535 "Garant" is used. It allows you to manually turn on the fire alarm.

Where the detector is used

Instrument IP 535 "Garant" is used to turn on the alarm in case of fire. It is designed for installation in areas where there is a risk of explosions.

The detector is suitable for work in places where the explosion hazard class is 0 and below. In such areas, it can be connected to an intrinsically safe loop. These can be devices like "Yakhont I" and others like it, creating the necessary conditions.

When used in areas safe from explosions, IP 535 "Garant" can be connected to a loop that is not intrinsically safe. Additional current limiting elements are notneeded. But here it is important to take into account that the detector is unipolar, therefore, with alternating voltage in the loop, it is necessary to use an additional diode.

The detector can be operated in various temperature conditions, it is used even outdoors in the north, where the temperature is constantly low. The operating temperature range is from minus fifty-five to plus seventy degrees. At the same time, the relative humidity of the ambient air at forty degrees Celsius should not exceed 93%.

Device device

Fire detector IP 535 "Garant" consists of the following elements:

The case, which is made of impact-resistant material (cast Armamide)

Glass cover. The kit also includes another spare cover, allowing you to restore the device after a trip

LED built into the button

Mounting bar

Board with electrical circuit elements

Terminals for connection to the loop

There is an inscription on the body of the device: "Fire, break glass, press the button."

Working principle

The device is powered by several redundant contacts and a rectifier bridge.

When the button is pressed, the current increases in the loop, its strength is limited by the resistor. This turns on the built-in LED. IP 535 "Garant" transmits a fire alarm by pulling the drive element.

Key Featuresappliance

Detector IP 535 "Garant" has the following advantages:

The body is highly durable. It well protects the internal elements of the device that perform the main functional task

It has anti-vandal protection

Has a high degree of vibration resistance. This is ensured by the compound layer with which the device is covered

Compound potting also covers the wiring diagram

Works well in various temperatures and high humidity

High reliability is achieved due to the absence of mechanical impact

Terminals do not oxidize

Can be installed in line with various types of control and receiving devices

A variety of cable types can be connected

When the voltage in the loop is twenty-four volts, the detector has a current strength of less than ten microamperes. In fire mode, this value is on the order of twenty milliamps (19.9-21.1 mA). The electrical strength of the insulation must be greater than 0.75 kilovolts, and the electrical resistance of the insulation must be greater than 20 MΩ.

The device will work when connected only to a two-wire line, the voltage in which is from four to twenty-seven volts. This is the voltage required to power the detector.

The device has the following dimensions: length is 160 millimeters with fitting (without it 110 millimeters), width - 110 millimeters, depth - 70 millimeters. At the same time, the device weighs no more thanthree hundred grams.

Detector IP 535 "Garant" works throughout the entire time without interruption. In standby mode, the device is capable of operating up to sixty thousand hours. This means that the average life of the device is more than ten years.
