Description

Announcer security and fire manual electrocontact

The utility model relates to alarm devices and is intended to transmit an alarm to a fire alarm system.

Limestone security and fire detectors containing a cover with a central recess in which a transparent plate is mounted that can be moved with a contrast shutter in the pressed state and serves as a drive element for the contacts of the switch that changes the state of the alarm loop, the switch and the staff with electronic circuit are mounted on the plate attached to the inner surface of the lid, which is fixed to the base, and a pusher intended to be installed in the hole in the lid for

the return of the transparent plate and the contrast curtain to its original state after being triggered (US patent No. 4857679, class G08G25 / 12, 1989, and application WO No. 01/11585, class G08G25 / 12, 2001).

The disadvantage of these and other known devices is the complexity of the design of the mechanism for returning the detector to its original state after operation, as well as the high complexity of mounting the detector at the facilities.

The task to which the utility model is aimed is to simplify both the design and installation of the fire alarm.

MPK7O08O25 / 12

The task is achieved due to the fact that the detector is a fire-fighting manual electrical contact, containing a cover with a central hole, in which a transparent plate is mounted with the ability to move, fixed by the indicator curtain in the pressed state, while the latter serves as a drive element for the contacts of the switch that changes the state of the alarm loop , and a circuit board with an electronic circuit installed on the inserted carrier plate, on which the cover is also fixed.

A particular essential feature is that the detector is equipped with an optical indication circuit for standby mode and alarm notification receiving mode.

The information search carried out by the applicant did not reveal any known

detectors with a similar design (i.e., with the listed set of essential features), which allows us to conclude that the claimed technical solution meets the novelty criterion. Further, on the basis of the stated construction principles of the claimed design, a number of samples of these detectors were made, which, despite some structural differences, showed the performance of the product.

Thus, this technical solution meets all the eligibility criteria for utility models, and it can be provided with legal protection in this capacity.

The essence of the utility model is illustrated by drawings, on which;

in FIG. 1 shows the details of the detector disassembled;

figure 2 is the same, view from the opposite side;

on figs-section along aa in fig. 1.

The detector, made in accordance with the claimed utility model, consists of a base 1, on which a carrier plate 2 is fixed, on the last a board with an electronic circuit (not shown), a limit switch 3, and with the possibility of movement, a transparent plate 4 and contacting it are mounted spring-loaded indicator curtain 5. Also on

plate 2 mounted a compression spring 6 and a return spring 7. On the supporting plate 2, optical indicators of the standby mode and the reception mode of the alarm notification (not shown) can be installed. In the lid 8, the central hole 9 is closed by a movable transparent plate 4 mounted on a carrier plate 2.

The detector is as follows. In the initial position, the transparent plate 4 is in place with the indicator curtain 5 in the upper part, the spring 6 is in a compressed state, while

indicator curtain 5 in the Central hole 9 (in the upper part of the latter) is not visible. This position (standby) is indicated by flashes (flashing) of the green indicator.

The annunciator switches to the mode of sending a message when pressing on the transparent plate 4, which, when mixed, releases the indicator curtain 5. The latter, under the action of the spring 6, goes down, acts on the switch 1 and 3 and is fixed with JTOM in the pressed COOL CONNECTION. I turn on the switch 3, I change the state of the alarm loops and an alarm is sent to the control panel. The indicator light 5 (in its lower position) appears in the upper part of the central hole 9, and thereby indicates that the detector is in the alarm state. This mode (transmitting an alarm message) is indicated by flashes (flashing) of the indicator, usually red.

The return of the detector to its original position is carried out using a special key (not shown), which is included with the detector and is located at the service personnel.

Thus, the utility model simplifies the design and installation of the detector.

Claims (3)

1. The security and fire detector is a manual electrical contact, comprising a base, a front panel with a central hole, under which a spring-loaded pressure plate having two stable positions is mounted, which is fixed in the pressed position by a spring-loaded indicator curtain, the latter serving as a drive element for the switch contacts that changes the state of the alarm loop, and a board with an electronic circuit, characterized in that it is equipped with a carrier plate on which mounted spring-loaded indicator curtain, while said plate is fixed on the base, and a front panel is mounted on it. 2. The detector according to claim 1, characterized in that the circuit board with an electronic circuit is mounted on a carrier plate. 3. The detector according to claim 1 or 2, characterized in that it is equipped with an optical indication circuit of the standby mode and the reception mode of the alarm notification.
