What is IPR? This question is set by many consumers who are thinking about installing such a useful device.
The abbreviation "Ipr" is deciphered as "manual fire detector". This device has provided a good service to many residents of our country, warning them of possible fire and saving lives. Let's figure out what the detector is, what the principle of its operation is and where it is preferable to install it.
What is a manual fire detector?
The fire detector is a technical system designed to detect fire and notify about it. Quite often this term is associated with a point-type autonomous device installed in a certain room. Such a device immediately gives the appropriate signal. However, in fact, 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 a part of any automated fire fighting and alarm system. It is designed to work with a signal-trigger device and a fire (or security-fire) receiving and monitoring device.
Why do I need a fire detector?
The fact is that when a fire occurs, not only property, but also people suffer. Rescuers are very concerned about the problem of deaths in fires. And ignition can arise not only in the house, when a person tired after work, distracted, forgetting that the stove warms up the soup. According to statistics, more than fifty percent of fires that resulted in death occur at night when a person sleeps. He does not feel the smoke. An autonomous detector helps prevent a fire.
Fire can occur anywhere: in places of large crowds (in shops, shopping centers, theaters), in an archive or library, a hospital and so on. Here, not only automatic detectors, but also manual ones, for example, the fire detector IPR 513 will come to the rescue. It is placed on the wall, at a height of about one and a half meters from the floor level and is activated manually, 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 alarm does not provide a function to help detect a fire. This type is designed to give an alarm signal to the fire alarm and fire extinguishing system manually. In this case, an alarm message is sent to the electrical circuit of the alarm loop. A person, having detected a fire, should press the corresponding button on the detector.
Typically, manual fire detectors are installed on evacuation routes, which should be available in case of fire. It is important to remember that the space intended for installation of the device should be well illuminated (the illumination level should not be less than 50 LK).
This device can be installed either inside a building on a wall or a structure (the distance between the detectors should not exceed fifty meters) and outside the building. In the second case, the distance between the instruments should not be more than one hundred and fifty meters. According to the rules of fire safety, within 0.75 meters of the installed device there should be no objects or mechanisms that prevent its access. For example, the installation of an IPR in a cabinet is prohibited.
Why program the address in the device?
In order to shorten the time to determine the localization of the source of ignition, it is very important to ensure that the signals of the device are correctly addressed. If it is an office or administrative building, then it can be set up to the floor. If it is a multi-storey residential building, it is very important to specify the targeting to the accuracy of the apartment.
The use of non-targeted IRPs may require the installation of a large number of rather long loops.
Today, even on relatively small real estate 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 the inclusion in a train of several hundred manual and automatic fire detectors, sirens, control modules and other equipment.
The principle of operation of addressable fire detectors
What is IPP address? What is the principle of its work? The point is that addressable devices can only work with compatible control panels. The control panel can be either address or address-analog. Data exchange between the IRP and the control panel is carried out according to the relevant protocol.
At the time of polling, which is carried out in standby mode, the addressable fire detector for some time turns on the indication. Next, with the next poll, the activated state is written off, and a command is given to turn on the indicator. Then, the address of the IPP is displayed on the device's display. Some devices can be equipped with short-circuit isolators.
Characteristics of the IPR 513
Fire detector manual IPR 513 is a four-wire device intended for the signal "Fire" in the manual mode. It is an element of fire protection and alarm.
The device is powered by a control and receiving device. Also, power can be supplied via Rorp when connecting the IPR 513 via a four-wire circuit. Compatible with any control panel that senses the detector's trigger signal as a connection to an additional resistor loop via a built-in dry contact relay.
An alarm signal is generated when the button is pressed. To remove the signal, it is necessary to return the button to its original position by means of a pin whose diameter is no more than three millimeters.
Both automatic and manual device-detector will help to avoid a fire, therefore it is not necessary to neglect its installation. Thanks to this device, the ignition will be quickly eliminated, which means that the lethal outcome and significant property damage will be excluded. Ensure the safety of your home or office, install fire protection systems.
