What is IPR? This question is asked by many consumers who are thinking about installing such a useful device.
The abbreviation "Ypres" stands for "manual fire detector." This device has rendered a good service to many residents of our country, warning them of a possible fire and saving lives. Let's see what the detector is, what is the principle of its operation and where it is preferable to install it.
What is a manual fire detector?
A fire detector is a technical system designed to detect fire and to notify about it. Quite often, with this term, a point-like autonomous device that is installed in a certain room is associated. Such a device immediately gives an appropriate signal. However, in reality, when answering the question “what is IPR?”, It should be understood that the sensor is only part of the fire protection system.
The detector is part of any automated fire extinguishing and alarm system. It is designed to work with a signal-starting device and a fire (or security and fire) receiving and control device.
What is a fire detector for?
The fact is that in the event of a fire, not only property suffers, but also people. Rescuers are very concerned about the problem of death in fires. Moreover, a fire can occur not only in the house, when a person who is tired after work is distracted, forgetting that soup is heating up on the stove. According to statistics, more than fifty percent of fatal fires occur at night when a person is sleeping. He does not feel smoke. A self-contained detector helps prevent fires.
A fire can occur anywhere: in crowded places (in shops, shopping centers, theaters), in an archive or library, hospital, and so on. Here, not only automatic detectors will come to the rescue, but also manual ones, for example, the IPR 513 fire detector. It is placed on the wall, at a height of about one and a half meters from the floor level and is manually activated by pressing a special button.
Features of manual fire detectors
So, to the question "what is IPR?" we answered. Now let's figure out what its features are.
The manual fire detector does not have a function to help locate a fire source. This view is intended to give an alarm to the fire alarm and fire extinguishing system manually. In this case, an alarm notification is transmitted to the electrical circuit of the alarm loop. A person, having detected a fire, must press the corresponding button on the detector.
As a rule, manual fire detectors are installed on evacuation routes, which should be accessible in the event of a fire. It is important to remember that the place intended for installation of the device should be well lit (the level of illumination should not be less than 50 Lux).
This device can be installed both inside the building on the wall or structure (the distance between the detectors should not exceed fifty meters), and outside the building. In the second case, the distance between the devices should not be more than one hundred and fifty meters. According to the fire safety rules, within 0.75 meters from the installed device there should not be objects or mechanisms that impede its access. For example, installing IPR in a cabinet is prohibited.
Why program the address on the device?
In order to reduce the time for determining the localization of the source of ignition, it is very important to correctly ensure the targeting of the device signals. If we are talking about an office or administrative building, then it can be set up to the floor. If we are talking about a multi-storey residential building, it is very important to indicate the targeting accurate to the apartment.
The use of conventional IPRs may require the installation of a large number of rather long loops.
Today, even at relatively small immovable objects, address and address-analog systems are used, for example, IPR 513 address. They provide a good level of fire protection, automatically control different systems, and allow several hundreds of manual and automatic fire detectors, sirens, control modules and other equipment to be included in one loop.
Principle of operation of targeted fire detectors
What is IPR Address? What is the principle of its work? The fact is that addressable devices can only work with compatible control panels. Control panels can be either address or address-analog. Data exchange between the IPR and the control panel is carried out according to the corresponding protocol.
At the time of the survey, which is carried out in standby mode, the addressable fire detector for some time includes an indication. Then, during the next poll, the activated state is written off, and a command is issued to turn on the indicator. Then, on the display of the device, the address at which the IPR is installed is displayed. Some devices may include short circuit isolators.
Characteristics of IPR 513
The manual fire detector IPR 513 is a four-wire device designed to provide a “Fire” signal in manual mode. It is an element of fire protection and alarm.
The device is powered by the control panel. Also, power can be supplied through Rorp when connecting IPR 513 in a four-wire circuit. It is compatible with any control panels that sense the detector signal in the form of an additional resistor connected to the loop through the built-in Dry Contact relay.
An alarm is generated after pressing a button. To remove the signal, you must return the button to its original position using a pin, the diameter of which is not more than three millimeters.
conclusions
Both an automatic and a manual detector device will help to avoid a fire, so you should not neglect its installation. Thanks to this device, a fire will be quickly eliminated, which means that a fatal outcome and significant damage to property will be eliminated. Ensure the safety of your home or office, install fire protection systems.
