Connection diagram for smoke sensor IP 212 45. Purpose and application

Operating principle of the IP 212-45 detector

The fire detector allows you to detect the appearance of smoke on early stage at the place of its installation. When the detector is triggered, its internal resistance decreases and the indicator light becomes constant. The detector is powered and the “Fire” signal is transmitted via a two-wire loop. In standby mode, the indicator blinks at intervals of 1 every 5 seconds.

Scheme for connecting the IP 212-45 detector to a two-wire alarm loop

The fire detector IP 212-45 consists of two main modules - a sensor and a socket. The sensor is an optical-electronic system and radio elements in a plastic case. Convenience of installation, maintenance and time saving is provided by a detachable connection of the sensor to the socket.

The contact base of the IP 212-45 detector is designed on the principle of screwless contacts, which ensures high reliability of electrical contact and saves time during installation.

Short-circuit contacts 3 and 4 allow you to create a “Fault” mode in the PPK alarm loop if the sensor is removed from the socket.

Regular city ​​apartment is quite a fire hazard. The source of ignition can be anything - heated electrical wiring, faulty household appliances or a forgotten iron. The greatest danger in terms of fire is the kitchen. Besides household appliances, which has great power, there is a main danger - open fire. A stove left without constant supervision can cause a lot of trouble. You can find out about a fire in the kitchen without connecting an expensive security and fire system with lots of wires. The autonomous fire detector IP 212 has proven itself well for use at home.

Purpose and application

The IP 212 fire alarm sensor is intended for installation in residential, administrative and utility premises. Its peculiarity is that there is no need for connection to wires, power supplies and information boards.

The sensor is completely autonomous; it receives energy from a battery. The fire detector IP 212 reacts to the appearance of smoke in the room, which gives a light and sound signal.

This device can be installed in the following places:

1. Residential apartments. The installation location can be a kitchen, a corridor or one of the rooms.
2. Offices. So as not to spoil new renovation gating walls for wires fire alarm system, you can use the autonomous smoke detector IP 212.
3. Libraries and archives. As a rule, the rooms in which various archival materials are stored are visited very rarely. These rooms are quite large and are not visible visually.

As a rule, all buildings and structures are built and renovated on a turnkey basis. Laying new communications requires time and money. In essence, this is a repair, with all its consequences. Installation of autonomous sensors is the best option, both for the safety of premises owners and to meet the requirements of regulatory authorities.

For residential apartments the installation of such devices is a unique opportunity to find out about a fire at an early stage, when the fire is small and you can extinguish it yourself.

Device and principle of operation

Firefighter smoke detector IP 212 has a fairly simple device. It is designed for do-it-yourself installation without the involvement of specialists.

The detector consists of the following parts:

1. Housing made of white durable plastic.

The IP 212-45 connection diagram will help you independently install an instant fire response device. Owners of private properties and commercial properties are confident that the fire alarm will detect even the slightest amount of smoke.

Functional characteristics

The device reacts to the proportion of smoke in the air. The effect of scattering radiation from a fire by gray smoke is used here.

When measuring the smoke level, the indicator is configured to switch to the “Fire” state. At the same time, the internal resistance decreases to 1 kOhm. The indicator glows bright red, continuous in fire mode and intermittent in normal conditions.

The functionality of the alarm is checked by a special device in testing mode.

Design and operating procedure

Smoke IP 212-45 is an optical electronic device. In standby mode, the indicator indicator blinks at a frequency of 12 times per minute. When there is smoke, the internal resistance of the device decreases, the signal is transmitted through a two-wire loop, the indicator lights up brightly and constantly.

The IP 212-45 fire detector kit contains two detachable elements: a signaling device and a socket.

Structurally, the device consists of a board with radio components mounted in a plastic case and a removable smoke chamber.

The removable and detachable design is effective and time-saving during installation and technical maintenance of the device.

The product passport must contain the connection diagram for IP 212-45. A device that consumes electricity requires reliable electrical contacts. The detector has contacts without the use of screws, which adds safety in operation and reduces assembly time.

Removing the device from the socket is accompanied by the formation of a “Fault” signal in the loop connection. Technically, the signal supply is achieved by designed short-circuited contacts No. 3 and No. 4.

The alarm operates 24 hours a day without interruption.

The fire smoke detector IP 212-45 is configured to work with control and receiving devices that respond to a decrease in the internal resistance of IP 212-45 and provide voltage in the alarm zone in the range of nine to thirty volts.

Installation of the device

One fire detector serves 80 square meters premises with a ceiling height of 3.5 meters. But according to the rules fire safety Even in a ten-meter room, sensors are installed in duplicate.

The IP 212-45 sensor is connected on the ceiling, on the wall and in the space between the suspended and base ceilings. On suspended ceiling The signaling device is secured with a mounting ring. The standards for the location of devices are as follows:

• the distance between adjacent ceiling sensors is nine meters;
• the distance between the walls is no further than 4.5 meters;
• the geometry of the room is required to be rectangular, without differences in ceiling heights exceeding 0.4 m and without appendixes in the contour; If the conditions are not met, the number of sensors is increased.

Installation of the device is simplified due to the versatility of the IP 212-45 connection diagram.

The detector block contains four contacts:

No. 1 - For a remote indicator.

No. 2 - Positive voltage output.

No. 3 - Negative voltage terminal.

No. 4 - To generate the “Fault” signal.

The cable for connecting one or a group of sensors is chosen to be non-flammable, for example, a low-toxic copper cable with a non-flammable mica barrier KPVSVng(A)-FRLSLTx 1 x 2 x 0.5.

The connection diagram for IP 212-45 is designed for single and group cases. When connecting the group, a resistor is soldered into the far sensor block.

The mounting fasteners tend to slip out of your hands and roll into inaccessible places. The developers of IP 212-45 provided a connection without screws. The device block is equipped with 4 holes. The cable core is stripped to the length of the upper phalanx index finger. If the installer has a ruler in his pocket, then the wire is stripped to one and a half centimeters. The prepared core is inserted into the hole, and the flag is moved to the terminal with a screwdriver. If the installation operations are carried out correctly, the technician will hear a click - this means that the core is fixed in the terminal.

Upon completion of installation of four terminals according to the connection diagram IP 212-45, they are tested for functionality.

Technical specifications

The device is small in volume - diameter 9.3 centimeters and height 4.6 cm. The assembled weight is 210 grams. When a structure falls from the ceiling, physical injury is excluded.

Manufacturers guarantee a ten-year service life of the alarm.

The interval between the moment of smoke and the operation of the device does not exceed nine seconds. This time is 4-6 times less than the linear horizontal speed of fire spread both in a residential building and in an industrial building.

The disadvantage of IP 212-45 is that the device reacts to both smoke and dust. To avoid false triggering of the device, the chamber is cleaned with a vacuum cleaner. Electronic equipment is vacuumed in the “blow” mode. Periodicity preventive measures- once every six months.
