Description

The proposed technical solution relates to the field of measuring technology and can be used for continuous monitoring of the health of circuits, components and devices included in the fire alarm system.

The security and fire control panel “S2000” is known [https://bolid.ru/production/archive/s2000.html]. It is designed to work as part of an addressable security alarm system. Used to arm, disarm and display events occurring in the system. Information interaction between the S2000 console and ISO Orion devices is carried out via a wired RS-485 communication line.

The device provides display of system messages on a character liquid crystal screen and their storage in a non-volatile buffer (archive) with the ability to view. Controls the display of section states on the “S2000-BI” and “S2000-BKI” display blocks. For better perception of messages, it is possible to specify text descriptions of sections and users.

Allows you to manage sections (arm, disarm) using a PIN code on the remote control itself or on the S2000-K and S2000-KS keyboards, Touch Memory keys or Proximity cards from any device that has an input for connecting a reader , from S2000-BKI units, SMS messages via UO-4S.

Provides differentiation of user access rights to management functions.

It has the function of automatically controlling the outputs of control panels, starting and relay units according to 35 different programs.

It has the ability to connect a printer with a serial RS-232 interface for documenting events or a PC with AWP "S2000" software for displaying events, states of sections and alarm loops.

Ensures the transmission of notifications by devices "UO-4S", "S2000-PP" and, to a limited extent, by devices "S2000-IT" and "UO Orion".

If it is necessary to check the operability of any similar fire alarm and alarm control device, for example:

- Security and fire control panel "Signal-20" [https://bolid.ru/production/orion/control-devices/signal-20.html#download]

- Security and fire alarm and control unit "Signal-20P" [https://bolid.ru/production/orion/control-devices/signal-20p.html]

- Security and fire control panel "S2000-4" [https://bolid.ru/production/orion/control-devices/s2000-4.html]

To ensure the correct processing of signals from the smoke fire detector loop, it is necessary to test the device itself locally with an active and operational loop, or connect the loop to the device in a laboratory setting.

To quickly check the functionality of such devices, a compact device for testing smoke fire detector loops is used, simulating an alarm loop consisting of two smoke fire detectors.

But for known testing and testing devices, including the prototype device for testing smoke fire detector loops, testing requires from 2 to 3 people, depending on the distance of the device and the monitoring and control panel. One of the employees must always be near the control panel of the fire alarm system to transmit information. The second employee on the active loop simulated a malfunction, fire and attention (liquid smoke was used for this), a short circuit, and a break.

To limit the verification to only one person, use special verification devices, which are described below.

The 620 Tempo circuit tester is known (https://skomplekt.com/tovar/1/7/5155821602/).

The known device contains a housing, inside of which a power supply and an indication unit are installed. The tester is connected to security or fire alarm loops with normally closed or normally open contacts. When the state of the contacts of the alarm sensors changes, the tester display unit emits a sound signal.

The disadvantage of the solution is the insufficient breadth of its functionality.

The disadvantage is due to the inability to check the functionality of fire detectors, for example, smoke detectors. Using a known device, it is possible to check only the integrity of the loop circuit, since the power source in the portable device produces a voltage that is insufficient for the operation of fire detectors. To test the functionality of a fire detector, it is required that the test current parameters (voltage and current) be equal to the operating current parameters (voltage and current) in the fire alarm circuit.

The portable fire alarm loop testing device (RU117642U, published: 06/27/2012), chosen as the prototype, does not have these shortcomings.

The prototype device contains a housing with a power supply located inside it and an electrical circuit integrity indicating unit, additionally equipped with a voltage converter installed inside the housing, connected at the input to the power source, and at the output to an electrical circuit integrity indicating unit, wherein the voltage converter provides the output voltage and current strength corresponding to the voltage and current strength of the fire alarm loop being tested.

Since the distance between the fire alarm device itself and its monitoring and control panel can be large, testing by one person in known testing devices (including a prototype) limits the functionality of such devices.

So the technical problem of the prototype is that, due to the presence of its own power source, it is also low-functional and allows you to test only an open circuit and the operation of the detector using two light indicators. The power source in the tester according to the prototype is needed to enable a voltage converter, providing an output voltage and current corresponding to the voltage and current of the fire alarm loop being tested. Accordingly, insufficient current from the power supply or a malfunction in the voltage converter that does not result in the required output voltage and current will be impossible to achieve effective testing.

In addition, the presence of a voltage converter and its own power supply complicates the testing device.

The purpose of the utility model is to eliminate these technical problems.

The technical result is the possibility of more functional testing of fire alarm smoke detector loops as part of an existing security alarm system. In addition, the design of the testing device is simplified.

The specified technical result is achieved due to the fact that a device for testing the loops of smoke detectors of fire alarms is claimed, containing a housing with an electrical circuit integrity indication unit placed inside it, characterized in that the terminals for connecting to the terminals of the loop of the fire alarm control panel are located on the outer casing of the case, where the negative and positive terminals are connected into a closed circuit, in which the terminal and additional resistors are located in parallel, where the additional resistors are activated through switches, and the negative terminal is connected to a toggle switch simulating a break, and the closed circuit in the area up to the resistors is made with parallel branches entering the connection through the switch to check for short circuits.

Preferably, the switches are push-button.

Preferably, additional resistors with parameters in the range of 1.5-2.2 kOhm are used.

Implementation of a utility model

The claimed device for testing fire alarm smoke detector loops consists of a housing 1 (see Fig. 1 - Fig. 3) with an electrical circuit integrity indicating unit located inside it.

What is new is that terminals 5 for connection to the terminals of the fire alarm control panel are located on the outer casing of the housing 1, where the negative and positive terminals are connected in a closed circuit in which the terminal 2 and additional resistors 3, 4 are located in parallel. where the activation of additional resistors 3 and 4 is performed through switches 6 and 7, respectively.

In this case, the negative terminal is connected to the toggle switch 9 for simulating a break, and the closed circuit in the area up to resistors 2, 3, 4 is made with parallel branches entering the connection through switch 8 to check for a short circuit.

It is preferable to select an additional resistor with a parameter of 1.5-2.2 kOhm based on Table 1 of the Operating Manual for the “Signal-20P” fire alarm control panel. This value is used with the following smoke fire detectors: IP212-3SU, IP212-41M, IP212-45, IP212-46, IP212-78, 2151E, 2210.

The utility model works as follows.

The device for checking smoke fire detector loops (see Fig. 2) through terminals 5 for connecting the device to the fire alarm control panel 11 via wires 17 is connected to terminals 10 for connecting the alarm loop of the fire alarm control panel 11. For displaying messages on the screen 14, outputting information from the monitoring and control panel 13 of the fire and security control panel 11, the latter is connected to the control panel 13 through the terminals of the wired communication line 12 via wires.

When the break switch 9 is moved to the “on” position, the circuit of device 1 is closed and the connection to the device of an alarm loop consisting of smoke fire detectors is simulated. There is an algorithm for processing and displaying the current state of the alarm loop (hereinafter referred to as the processing algorithm): the signal enters the processor 15 of the device 11, and then to the CPU 16 of the control panel 13. After processing the signal in the CPU 16, the current state of the alarm loop is displayed on screen 14 (taking ( VZShS)) (see Fig. 4).

When the break toggle switch 9 is switched to the “off” position, the circuit of the device 1 is opened, the processing algorithm occurs and the screen 14 of the monitoring and control panel 13 displays the current state of the alarm loop (break (OBR)) (see Fig. 5).

Next, the device returns to its original position by moving the break toggle switch 9 to the “on” position.

By briefly pressing the switch 8 (for example, made in the form of a push-button) to check the alarm loop for a short circuit, a short circuit of the alarm loop is simulated, the processing algorithm occurs and the current state of the alarm loop (SC) is displayed on screen 14 (see Fig. 6).

By briefly pressing the push-button switch 6 (for example, made in the form of a push-button) to check the alarm loop for attention, the signal “attention of the alarm loop” is simulated, the circuit of the simulation device is opened through the additional resistor 3. The processing algorithm occurs and the current state of the alarm loop is displayed on screen 14 ( attention (ATTENTION)) (see Fig. 7).

By briefly pressing the push-button switch 7 (for example, made in the form of a push-button) to check the alarm loop for fire, the “fire alarm loop” signal is simulated. The simulation device circuit opens. The processing algorithm occurs and screen 14 displays the current state of the alarm loop (fire (fire)) (see Fig. 8).

Thus, the device for testing smoke fire detector loops allows you to quickly check the equipment by one person at the installation site of the equipment and test five different states of the fire alarm control panel 11, in contrast to the possibility of checking only two states in the prototype device.

This shows the higher functionality of testing smoke detector loops of an existing fire alarm system. In addition, the device according to the claimed utility model does not require the use of a power source and a voltage converter. This allows the design of the testing device to be simplified.

Based on the device according to the declared utility model, a prototype was created, which was successfully tested by one person on the S2000 fire alarm control panel [https://bolid.ru/production/archive/s2000.html]. Tests have shown the ability to check up to five different states of smoke plumes: pickup, open, short circuit, attention, fire (see Fig. 4 - Fig. 8).

The claimed loop (thermal) testing device can work with various fire and security alarm devices, for example:

- Security and fire alarm and control device "Signal-20" [https://bolid.ru/production/orion/control-devices/signal-20.html#download],

- Security and fire control reception and control unit "Signal-20P" [https://bolid.ru/production/orion/control-devices/signal-20p.html],

- Security and fire control reception and control unit “S2000-4” [https://bolid.ru/production/orion/control-devices/s2000-4.html].
