Any premises - office, store, apartment or warehouse - are constantly at risk of fire. Its cause can be anything - a short circuit in the electrical wiring, a malfunction of electrical appliances, spontaneous combustion of a material, or a human factor. Any property owner wants to protect their property from destruction. For organizations of a certain type of activity, the presence fire alarm is prerequisite to open an enterprise and carry out work. A completely logical question arises: how to equip a fire alarm at a facility inexpensively, reliably and in accordance with existing requirements. The answer to this question may be the installation of an IP 101-1A detector. This device combines reliability, simplicity and affordability.

Purpose and scope

Fire detectors IP 101-1A-A3 and IP 101-1A-A1 are intended to detect signs of fire in heated warm rooms. An alarm signal occurs when the temperature rises above the threshold specified by the sensor. The detectors have a 24-hour operating mode. Presentable appearance(a small cylinder made of white plastic) makes it possible to install them in premises of the highest status.

Detectors work together with other control sensors in the system security and fire alarm system. Their design provides the ability to connect to any DC loop.

Heat detectors IP 101 1A can be installed in the following rooms:

• in warehouses and storage facilities for various purposes;
• in offices and government institutions;
• in the offices of management staff;
• in banks and post offices;
• in cafes, shops and stalls;
• in apartments and garages.

The devices operate only on heat, without reacting to light sources, smoke or gas.

Device and principle of operation

The IP 101 1A detector is a compact device with a fairly simple but functional design

It consists of the following parts:

1. Frame. The housing consists of a base and a cover with air holes. The base is equipped with terminals for connecting the device to the alarm loop.
2. The electronic unit. It has an indicator light, a temperature sensing element, an electronic locking key and an electrical diode circuit.

Space scanning is carried out automatically by periodically sending pulses to the thermoelement. When the control temperature is reached, the resulting pulse causes a short circuit in the circuit, the signal from which is sent to the control equipment. The LED lights up continuously, indicating the location of the triggered sensor.

Features of the device

Heat detectors of the IP 101 series compare favorably with heat sensors of other designs. They do not have fusible connections and bimetallic petals, which are not highly reliable and often give false signals.

In addition, these devices have the following features:

• signal from temperature sensor analyzed by a microprocessor;
• An alarm signal is generated by changing electrical parameters;
• the presence of a light indicator that gives signals corresponding to the operating mode;
• active analysis of indoor air temperature;
• receiving power directly through the loop;
• no need for polar connection;
• adaptation to electrical parameters control and receiving devices fire systems.

The design of the lid allows you to aesthetically and harmoniously place the device in various rooms.

Advantages and disadvantages

Like anyone else technical product, heat detectors have their pros and cons.

The advantages of the product include the following indicators:

• high speed temperature status check (every 6 seconds);
• accuracy of the operating threshold due to current measurement;
• no unreliable mechanical relays;
• no need to install a separate power line;
• lack of connection polarity;
• no adjustment of the device resistance is required when connecting to security systems;
• quick return to standby mode after triggering;
• light weight and size, which allows the device to be placed on thin bases without embedded parts;
• affordable price (today - within 150-225 rubles).

The disadvantages of products in this series include the following:

• detectors cannot operate in cold weather;
• a chemically active environment is an obstacle to installing sensors;
• It is not possible to use the detector in GSM systems.

Despite minor disadvantages, IP 101 detectors are well-deservedly popular and in demand.

Main technical characteristics

The IP 101 1A detector has the following specifications Things that potential buyers should pay attention to:

• weight - 90-100 g;
• size - 60-65×25-30 mm;
• supply voltage - 10-25 V;
• operating temperature - from 0°C to + 76°C;
• response temperature - + 70°C (± 6°C);
• response time - 90-600 seconds (depending on the rate of temperature increase);
• coverage area - 25 m;
• return to standby mode after shutdown - 2 seconds;
• relative indoor air humidity - up to 95%;
• average service life is 10 years.

The manufacturer guarantees the detector for 36 months after installation.

Installation of heat detectors

The devices can be installed simultaneously with other control sensors, as well as after their installation. The number of detectors installed depends on the technical capabilities of the security system.

The devices are fastened to the ceiling, since in the event of a fire this is where the temperature is highest.

On a note: The sensor from the sensor is installed at a distance of no more than 5 m over the entire ceiling area.

Detectors can be mounted on any material. It can be concrete, wood, drywall or plastic. For soft materials Self-tapping screws are used for wood; for hard ones, plastic dowels and self-tapping screws are used.

After connecting the wires, the base of the housing is secured to the ceiling and the lid is closed. The devices in the circuit are connected in parallel.

Device maintenance is carried out quarterly and includes the following actions:

1. External inspection to identify mechanical damage on the sensor body and cable line.
2. Check that the sensor is securely attached to the base.
3. Cleaning the device from dust and dirt. Pay attention to cleaning the grilles through which air enters the sensor.
4. Checking the strength of the wire connections at the terminals.
5. Checking the device's functionality.

If a malfunction is detected, the device is sent to the manufacturer with appropriate explanations, and a new detector is connected in its place.
