We study the connection scheme of IP 212-45

The scheme of connection of IP 212-45 will help to mount the device of instantaneous response to fire. Owners of private properties and commercial facilities are sure: the fire alarm will catch even a small smoke.

Functional characteristics

The device responds to the proportion of smoke in the air. Here, the effect of scattering the radiation from the fire with gray smoke is used.

When measuring the smoke level, the indicator is set to go to the "Fire" state. At the same time, internal resistance decreases to 1 kΩ. The indicator glows bright red light, continuous in the "fire" mode and intermittent in normal conditions.

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

Device and operating procedure

Fire Smoke Detector IP 212-45 is an optical electronic device. In the standby mode, the indicator light flashes at a frequency of 12 times per minute. In case of smoke, the internal resistance of the device decreases, the signal is transmitted via a two-wire loop, the indicator glows brightly and constantly.

The complete set of the fire detector IP 212-45 contains two detachable elements: a signaling device and a socket.

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

Removable - detachable design is efficient and economical in time for installation and technical prophylaxis of the device.

In the product passport, the connection scheme of the IP 212-45 is mandatory. The appliance-consumer of electricity requires the reliability of electrical contacts. In the detector contacts without the use of screws, which adds safety in operation and shortens the assembly time.

The removal of the device from the outlet is accompanied by the formation of the "Fault" signal in the daisy chain connection. Technically, the signal is supplied by the designed short-circuited contacts # 3 and # 4.

The alarm operates 24 hours a day without interruptions.

Smoke detector FI 212-45 is configured to work with control and reception devices that react to the reduction of the internal resistance of the ИП 212-45 and provide voltage in the AL in the interval of nine to thirty volts.

Installation of the device

One fire detector serves 80 square meters of space at a ceiling height of 3.5 meters. But according to the rules of fire safety, even in a ten-meter room, the sensors are placed in duplicate.

Connection of the sensor IP 212-45 is made on the ceiling, on the wall and in the space between the suspension and the base ceiling. On the false ceiling, the signaling device is attached with a mounting ring. The specifications of the arrangement of devices are as follows:

• Between the neighboring ceiling sensors a distance of nine meters;
• Between the walls the distance is not further than 4.5 meters;
• The geometry of the room is required to be rectangular, without differences in the ceiling heights exceeding 0.4 m and without appendixes in the contour; If the conditions are not met, the number of sensors is increased.

The installation of the device is simplified due to the versatility of the connection circuit of the IP 212-45.

The detector pad contains four contacts:

# 1 - For remote indicator.

№2 - Positive voltage output.

No. 3 - Minus voltage output.

# 4 - To generate a "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-combustible mica barrier KPVSVng (A) -FRLSLTx 1 x 2 x 0.5.

The connection scheme of the fire detector IP 212-45 is designed for single and group cases. When connecting a group, a resistor is soldered into the remote sensor block.

Mounting fastening demonstrates the property of slipping out of the hands and rolling into inaccessible places. Developers IP 212-45 provided the connection without screws. There are 4 holes in the socket of the device. The cable core is stripped to the length of the upper phalanx of the index finger. If the installer has a ruler in his pocket, the wire is peeled off by one and a half centimeters. The prepared core is inserted into the hole, the flag to the terminal is moved with a screwdriver. If the mounting operations are carried out correctly, the master will hear a click - this vein is fixed in the terminal.

At the end of the installation of the four terminals according to the connection scheme, the ИП 212-45 is tested for operation.

Technical specifications

The device is small by volume - 9.3 centimeters in diameter, and 4.6 centimeters in height. The weight of the assembly is 210 grams. When the structure falls from the ceiling, physical injuries are 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 propagation both in a residential building and in a production room.

The disadvantage of IP 212-45 is that the device reacts to both smoke and dust. To avoid false alarms, the camera is cleaned using a vacuum cleaner. Electronic equipment is vacuum-cleaned in the "blow-out" mode. Periodicity of preventive measures - once every six months.
