Sensor connection ip 212 3su. Fire detector connection diagrams

Fire, which is a friend of man, in an instant can turn into a ruthless element that destroys everything around. It is not always possible to prevent fires at various facilities due to various objective and subjective factors. Identification of the primary signs of a fire is quite accessible if potentially fire-hazardous premises are equipped with various signal sensors and detectors. In the course of many years of refinements and improvements, the IP 212-3SU smoke detector was created - a unique device that registers the onset of a fire at the earliest stages.

Purpose and scope

The purpose of this device is to detect the presence in the air of signs of a fire, namely, solid particles of soot and products of evaporation of combustible liquids suspended in the air. The sensor works in the general system of fire and security systems and can be used in combination with other sensors, video cameras and fire extinguishing systems.

The device is powered from the loop of the security system. The detector has a narrow specialization and is not susceptible to heat and all kinds of radiation.

You can use it by installing in such places:

• in the rooms of residential, economic and administrative buildings;
• in the cabins of cruise ships and warships;
• in passenger railway cars;
• in basements and entrances of multi-storey buildings;
• in warehouses and storages of all types of materials;
• in kindergartens and schools;
• in hangars of any type;
• in cowsheds, pigsties, granaries and other premises for agricultural purposes;
• in shopping and entertainment centers;
• in garages and underground parking lots.

The list of these objects can be continued for a long time, since the IP 212-3SU sensors can be installed without limitation in any closed type premises. At the same time, it does not matter what microclimate is in these rooms. Sensors can be installed both in a store in the south of the country and in an unheated warehouse in the far north.

Device and principle of operation

The IP 212-3SU fire detector has a simple, but at the same time, quite effective design.

It consists of the following parts and devices:

• housing made of durable white plastic;
• a two-level smoke chamber with a system of internal partitions, which ensures unimpeded entry of smoke into the body, without letting light into it from the outside;
• a printed circuit board that receives and processes electrical signals and controls the device;
• LED continuously emitting a beam;
• a photodiode, whose task is to receive the reflected beam and convert it into a certain electrical impulse;
• indicator light.

A feature of the improved fire detector IP 212-3SU is the installation of a high-brightness LED with an amplifier. Thanks to him, smoke is indicated at an insignificant concentration.

On a note: To avoid false signals due to dust and insects, the case is equipped with a fine safety net.

The design of the smoke chamber is also unique, which allows smoke to enter the optical system, regardless of the direction of its movement.

The principle of operation of the product is based on a change in the electrical parameters of the photodiode when the light pulse is weakened. This change is recorded and processed by electronics and transmitted as digital information to the control device. The alarm is reset by turning off the power.

Features and advantages of the device

The improved IP 212-3SU smoke detector was manufactured taking into account many years of experience in operating similar products in this series.

As a result, this device has acquired such distinctive properties:

• original body shape design;
• resistance to various interferences;
• immunity to temperature changes;
• protection against radiation of any kind;
• unique shape of smoke chamber gratings;
• energy efficiency;
• high rate of smoke detection;
• the ability to work with different types of loops, thanks to the fifth terminal for an additional resistor;
• wide operating temperature range.

In addition, the installation of the device has become more convenient and faster thanks to the well-thought-out mechanism of the wire clamps.

Main technical characteristics

The latest models of the IP 212-3SU detector have the following indicators:

• price - 300-400 rubles;
• size - 89×50 mm;
• weight - 100 gr.;
• temperature range - from -40° С to +60° С;
• supply voltage - direct current 9-30 V;
• permissible air humidity - up to 98%;
• smoke detection time - up to 5 sec;
• service life - 10 years.

Due to these characteristics, the device is in demand for the equipment of many security and fire systems.

Installation and maintenance

Installation work on the installation and connection of smoke detectors is carried out in compliance with safety measures in accordance with the instructions for the product. Thanks to the design of the smoke chamber, the sensor can be installed in any position.

Places for installation

The surface for mounting the sensor can be:

1. Concrete slab. Plastic dowels and self-tapping screws are used as fasteners.
2. Wooden ceiling. Wood screws are used.
3. Suspended ceiling made of plastic or plasterboard. The sensors are attached through the cladding to the crate with metal screws.
4. Stretch ceiling. Fasteners are carried out to embedded parts with screws corresponding to their material.
5. Steel columns, beams and supports. The best option is to fasten with bolts and nuts through through holes.
6. Steel cables and power cables. The sensor is fixed, either with non-ferrous metal wire, or on special clamps.

Avoid mounting appliances in the corners of rooms where smoke is the last to enter.

Mounting the detector

The installation of the device is carried out in accordance with the general scheme of the security and fire system.

It is carried out in the following sequence:

1. Carrying out the marking of the surfaces on which the devices will be installed.
2. Drilling holes for mounting.
3. Fixing sensors in place.
4. Connecting the wires of the alarm loop to the detectors.
5. Leading the wires from the sensors to the junction box and connecting the power supply.
6. Checking the functionality of the detectors. The check is carried out using a test aerosol or a probe introduced into the technological hole on the body.

When planning and projecting, the area that can be controlled by one device should be taken into account.

Instrument Maintenance

Reliable and trouble-free operation of the smoke detector is possible only if the operating rules and timely maintenance are observed.

Maintenance of sensors should be carried out at least once every 6 months.

It consists of the following steps:

• cleaning the outer surface from dirt and dust;
• removal of accumulated debris from the smoke chambers with the help of a jet of air;
• cleaning the LED and photocell;
• checking the reliability of the wire connection;
• device performance testing.

Before carrying out repair work, it is recommended to remove the sensors. Contact with mortar, chemically active liquids can cause corrosion of the metal and a violation of the aerodynamic qualities of the smoky box. In addition, sensors can be broken by heavy repair equipment.

During repair, the detectors must be stored in a dry room, in a package. After installation, their performance is checked without fail.

TECHNICAL DATA IP 212-3SU

Installation of fire detectors, of course, implies their connection to a fire alarm loop. The connection diagram for fire detectors is shown below. Considered two-wire (most commonly used)

• fire smoke detectors (DIP),
• thermal fire detectors (IP),
• manual fire detectors (IPR).

The wiring diagram for security detectors is shown on another page.

The fire alarm loop can simultaneously contain detectors of one or more (combined alarm loop) of the specified types. In addition, the connection diagram of fire detectors may provide for the activation of a fire alarm control panel (generation of a "fire" notification) when only one fire alarm loop sensor is triggered or when two or more fire detectors are triggered. (such an organization of the fire alarm loop, after the operation of one detector, generates an "attention" signal).

Addressable fire detectors also have their own connection scheme. I want to note that the connection diagram of fire alarm sensors can vary (depending on the type of control panel), however, the differences are insignificant, mainly affecting the ratings (values) of additional (ballast), terminal (remote) resistors.

In addition, various types of control panels allow the connection of a different maximum number of smoke detectors in one alarm loop - this value is determined by the total current consumption of the sensors. Remember - the current consumption of a smoke detector depends on its type.

All types of conventional two-wire smoke detectors use the same pin numbering: (1,2,3,4).

The wiring diagrams for the outputs of smoke detectors from different manufacturers may visually differ slightly (options 1.2), but, from the point of view of the electrician, they are identical, because the outputs 3.4- are short-circuited inside the detector housing.

However, the second option has a serious drawback - when the detector is removed from the socket, the control device will not detect its absence and will not generate a "malfunction" signal. Therefore, it is better not to use it.

Note!

• Even for one specific type of fire alarm control panel, resistors Rdop. may have different values ​​(it is determined by the current consumption of various types of smoke detectors, read the device data sheet carefully).
• The wiring diagram shown fire manual call point valid when normally closed electrical contacts are its actuating element. For example, for IPR 3 SU, this connection scheme will not work.
• Thermal fire detectors are connected according to the above diagram if they have normally closed contacts (most of them).
• A situation may arise when an IPR connected according to the scheme shown (recommended by the device passport) for an alarm loop that provides for triggering by two sensors, when triggered, causes the signal "attention" instead of "fire" to be generated by the receiving control device. Then try to reduce the value of the resistor (Rdop), through which this IPR is connected to the alarm loop.
• Before connecting (installing) addressable detectors, their address must be pre-programmed.
• The connection of smoke detectors requires compliance with signaling loop polarity.

Probably every owner wants his house, dacha and even industrial premises to always be under reliable control and protection. It is for such purposes that there is a fire detector SP 212-3su. This sensor gives a signal when a fire is detected and when there is minimal smoke, within the radius of its work.

The detector ip 212-3su is the embodiment of twenty years of experience in the production and design of fire detectors.

If smoke appears within the operating radius of the device, an electrical signal is generated, which is transmitted to the control panel. If you decide to install this model on a suspended ceiling, then it will protect both the under- and above-ceiling space.

Innovation of the model ip 212-3su

The lower part of the smoke chamber catches horizontal smoke flows that spread along the ceiling. The LED, which was used in IP 212-3su, has a narrow radiation pattern, which, together with bright radiation, detects even minimal levels of smoke. The response threshold in this case is no more than 5 seconds. The photodiode crystal is on the same carrier along with signal amplification. This is the only sensor made in this way and with it the protection against electromagnetic interference is greatly increased.

The model is characterized by high sensitivity and the absence of false positives. It was these achievements that brought the un 212-3su to the first places in sales. He has patents for "industrial design" and "utility model".

A small, compact device manufactured with dimensions of 88.5x49.5. It is almost imperceptible, but at the same time, despite the same size, it quickly catches even the smallest streams of smoke when the fire has just begun. Ease of installation due to the good location of the contact group.

manufacturer's warranty

The manufacturer has established such warranty periods as 18 months after putting it into operation, but not more than 24 months from the date of manufacture. During the warranty period, all repairs of the detectors are carried out by the manufacturer. In such a case, the warranty period may be extended by the period that was spent repairing the defect. The warranty case occurs when the consumer has used the sensor in accordance with the instructions for use, storage and transportation.

Storage and operation

The detectors are stored in closed warehouses, in original packaging. Mandatory storage conditions protect devices from sunlight, moisture, mold.

When checking the service life of the devices, it was found that the failure time is about 60,000 hours, within 10 years.

Results

After listing all the advantages and innovations in the SP 212-3su model, we can safely say that choosing this model will not make you upset. Simplicity of appearance, the possibility of installation in suspended ceilings with the possibility of protecting the interceiling space, protection from dust - all these are the minimum transfers of the updated version of the fire detector. The most important advantage still remains that the sensor reacts even to minimal smoke and immediately transmits an “alarm” signal. Such a basic element as a fire alarm is constantly improving along with the quality and duration of its work.

The new generation of fire detectors IP 212-3SU, retaining all the advantages of its predecessors, is distinguished by even greater ease of installation and maintenance, high sensitivity in the absence of false alarms (including from fluorescent lamps), and low inertia. At the same time, the current consumption decreased by more than 2 times (up to 50 μA)! In addition, the new IP 212-3SU detector is made in a modern small-sized case, has a much more efficient testing system, is protected from dust and insects, its socket is designed to connect a fire-resistant FRLS and FRHF cable, and has a 5th contact for connecting an additional resistor in two-threshold loops. Modern design and technological solutions have made it possible to reduce the price of the updated IP 212-3SU.

Smoke chamber. The basis of the smoke optical-electronic detector is:

Rice. 1. Design IP 212-3SU

Optical pair - LED + photodiode (Fig. 1 a) and smoke chamber (Fig. 1 b, c), which determine the technical and operational characteristics. The two-level smoke chamber of the new IP 212-3SU detector was the result of a large amount of mathematical modeling and experimental research. Its lower part is perfectly coordinated with the horizontal smoke flows spreading under the ceiling. The vertical plates form 12 symmetrical sectors and provide a uniform flow of smoke from any direction to the central region of the smoke chamber (Fig. 1c), combined with its upper level, in which an optocoupler is installed, thus effectively protected from dust and from external illumination. The inner wall of the upper level of the smoke chamber was also constructed for the first time from 12 "traps" of LED radiation, cylindrical cells with a minimum level of re-radiation are black body simulators (Fig. 1 b). This reduces the level of the reflected signal of the LED, provides a low background signal of the receiver when dust accumulates on the chamber walls, and provides reliable protection against external illumination.

Light-emitting diode. To ensure low current consumption at high radiation brightness for the new IP 212-3SU detector, a high-performance GaAlAs IR LED TSAL6100 of the American company Vishay Semiconductors was chosen for special applications, including for smoke detectors. The highest technological level of production provides stability of characteristics at long terms of operation. This eliminates the effect of desensitization during operation, which often occurs when cheap, widely used LEDs are used in detectors. A distinctive feature of the TSAL6100 LED is a narrow beam pattern of ±10° and high radiation brightness, thanks to which the detector is able to detect even low levels of smoke. The high efficiency of the LED provided a low current consumption of 50 μA despite the pulse period of 1 s and an excellent response to exceeding the threshold - no more than 5 s!

A photodiode, or rather a photodetector, is our own unique development. IP 212-3SU is the only detector in which the photodiode crystal is made on the same carrier as the signal amplifier (Fig. 1a), which provides higher protection against electromagnetic interference than photodiode shielding. The amplified output signal of the photodetector has a much larger value compared to interference effects. The use of a two-level smoke chamber made it possible to reduce the length of the leads of the photodetector and further reduce the induced noise. The directivity of the photodetector is consistent with the shape of the smoke chamber.

Testing. Smoke detectors often use primitive methods of testing with a “screwdriver” or a button with unacceptably low reliability of the results: the detector can pass the test, but not respond to smoke. To ensure high testing efficiency in the new IP 212-3SU detector, the performance of all main elements, including optocouplers, is monitored by lowering the response threshold when the test button is pressed.

Detector design. The new detector IP 212-3SU has optimal dimensions Ø 88.5 × 49.5 - relatively small, not striking, but not so small and streamlined that weak streams of smoke do not fall into it in the early stages of fire development. The indication LED is located in such a way that its all-round visibility is ensured in the event of a detector triggering. The design of the detector socket has also been carefully designed: the location of the contact group provides a large free area for ease of installation when using fire-resistant FRLS and FRHF cable. A “fifth contact” is provided for connecting a current-limiting resistor in series with the detector and a contact for connecting a remote indicator.
