DEVICE FOR CHECKING THE PERFORMANCE OF THERMAL FIRE DETECTORS

Abstract

This utility model relates to devices used in automatic fire alarm and fire suppression systems (AFFS and PT) and is designed for testing thermal fire detectors, specifically the DPS-038. The device for testing the functionality of thermal fire detectors is designed as a thermos with a lid. A clamp is attached to the thermos body through a seal, to which a U-shaped handle is attached. The extended end of the handle is fixed inside a hollow bracket attached to a pole. The technical result of this utility model is an expanded arsenal of tools for testing thermal fire detectors. This eliminates the need for ladders or lifts, improving safety while working at height and minimizing the time spent on preparatory operations, as well as the use of open heat sources that could cause a fire.

Description

[0001] The utility model relates to devices used in automatic fire alarm and fire extinguishing systems (AFFS and PT), and is intended for testing thermal fire detectors, in particular DPS-038.

[0002] A portable device for testing automatic fire extinguishing system equipment is known (patent for utility model RU 210780, published 04.05.2022), designed to check the operability of the PIO-017 device (intermediate actuator) and DPS-038 fire heat detectors, and also allows you to check the serviceability of circuits.

[0003] A disadvantage of this device is the need to constantly disconnect the cable line with the SR connector from the PIO-017 device during monthly checks of the automatic fire alarm and extinguishing system. This can lead to damage to the cable and the connector if disconnected frequently. Since the PIO-017 device lacks loop integrity monitoring, there is a risk of incorrectly assessing the system's status and jeopardizing the safety of facilities. Furthermore, this portable device is intended solely for testing the functionality of the DPS-038 and the PIO-017 intermediate actuator and cannot be used to test other types of detectors, as it is designed and manufactured exclusively for use with the SR connector and the electrical parameters of specific device models.

[0004] The closest analogue in relation to the claimed utility model is an insert in a device for testing a thermal fire detector (patent for utility model RU 218714, published on 06 / 07 / 2023), designed to test the operability of thermal fire detectors by intensifying the flow of heated air directed at the remote sensitive element of the thermal fire detector.

[0005] A disadvantage of this device is the need for lengthy setup and preparation before testing the heat detector. This can also lead to uneven heating and inaccurate performance assessments.

[0006] The technical problem of the utility model is the creation of a structurally simple and easy-to-use device for testing various models of thermal fire detectors in hazardous areas during monthly checks of the automatic fire alarm and fire extinguishing system.

[0007] A device for testing the performance of thermal fire detectors, including a thermos with a lid attached to a pole, while a clamp is installed on the body of the thermos through a seal, to which a U-shaped handle is attached at one end, and its second end is designed with the possibility of fixing inside a hollow bracket attached to the pole.

[0008] The technical result of this utility model is to increase the rigidity of the device's structure. When assembled, the device is firmly attached to the pole, yet is structurally simple and easy to operate.

[0009] Fig. 1 shows a side view of the claimed device, where

[0010] 1 - thermos;

[0011] 2 - cover;

[0012] 3 - tension clamps;

[0013] 4 - U-shaped handle;

[0014] 5 - hollow bracket;

[0015] 6 - dielectric pole;

[0016] 7 - cover.

[0017] The device for testing the operability of thermal fire detectors includes a thermos 1 with a lid 2 screwed into its neck 7. On the body of the thermos 1, at the top and bottom, through rubber seals (not indicated in the figure), clamping clamps 3 are installed parallel to each other. A U-shaped handle 4 is fixed to the clamping clamps 3 with its short end, and one of its elongated ends is fixed inside a hollow bracket 5, fixed on a dielectric pole 6.

[0018] The device is used as follows. Thermos 1 is filled with hot water and closed with lid 2 by screwing it into neck 7 of thermos 1. Handle 4 is inserted tightly into bracket 5, where it is securely fixed. Next, lid 2 is unscrewed, and the device is brought to a heat fire alarm located on the ceiling of the room using dielectric pole 6. After the alarm is triggered, emitting a light and / or sound signal, the device is moved away from the alarm, allowing the alarm to cool and return to its original state. Thermos 1 is then resealed with lid 2 and removed from dielectric pole 6 by removing handle 4 from bracket 5.

[0019] Thus, the use of the claimed device for testing thermal fire detectors is safer and more convenient to operate.

Claims

A device for testing the operability of thermal fire detectors, including a thermos with a lid, fixed to a pole, characterized in that a clamping collar is installed on the body of the thermos through a seal, to which a U-shaped handle is attached at one end, and its other end is designed with the possibility of fixing inside a hollow bracket fixed to the pole.
