Abstract
Disclosed is a manual alarm button conversation device employed in the fire alarm system, comprising a button (3) with a pickup device (2) and a loudspeaker (1) provided inside, a conversation resetting button (4) which is linked with a convex block (8), and a switch (6) whose contact (7) matches the convex block. The pickup device (2) and the loudspeaker (1) are connected electrically with a circuit board (5). The circuit of the pickup device and the loudspeaker is communicated when the conversation resetting button is pressed down, thus realizing the conversation with the fire fighting guard center to know the details happened to each other.
Description
Technical field
The utility model relates to the talkback unit of hand push button in a kind of fire alarm system.
Background technology
In the NFA design specification of automatic fire alarm system, stipulate, architectural plane is every 30 meters necessary manual pull stations of design and installation, and require this button to be provided with the special-purpose jack of fire telephone, when finding the condition of a fire, be connected the back with this jack to fire watch center oral report dangerous situation for the staff by telephone for special use.This jack also has the staff and understands the intercommunication effect of situation everywhere to the fire watch center.But in routine duties, the staff carries telephone for special use all the time, in case the emergency of meeting is returned body and reached telephone for special use and then can delay time of fire alarming, incurs loss through delay fire extinguishing opportunity.If the staff has little time to reach telephone for special use and just fire hydrant button is pressed, the fire watch center then can only receive the report for police service signal and can not understand details, can not obtain emergent conversation between mutually in the fastest time to get in touch.
The content of utility model
The technical problems to be solved in the utility model is the deficiency that exists in the background technology for overcoming, and the talkback unit of manual pull station in a kind of fire alarm system that just can in time get in touch with center on duty without telephone for special use the time is provided.
Technological improvement of the present utility model is: in button, be provided with pick-up and loud speaker, and intercommunication reset button and projection interlock, projection cooperates with the contact of switch.
Further technological improvement of the present utility model is: projection is supported by spring, and pick-up and loud speaker are electrically connected with circuit board.
Good effect of the present utility model is: owing to installed projection, pick-up and the loud speaker that links with the intercommunication reset button in manual pull station, the button and the former push-to-talk button that can play the intercommunication effect are integrated, the turning circuit by intercommunication reset button starting switch, and be communicated with pick-up and loud speaker carries out intercommunication, thoroughly solved just can not detail knowledge the other side situation without telephone for special use problem, make the staff at ordinary times or only need press the intercommunication reset button when running into the condition of a fire and just can carry out intercommunication and in time get in touch with the fire watch center.Because of this cover talkback unit volume less, can be installed in fully in the space of existing manual pull station, good concealment, not fragile, and low cost of manufacture, be fit to very much use in the existing fire alarm system, its biggest advantage is exactly can realize the intercommunication at staff and fire watch center at ordinary times or in emergency circumstances in the very first time.
Description of drawings
Fig. 1: structural representation of the present utility model (front).
The rearview of Fig. 2: Fig. 1 (removing bonnet).
Embodiment
As shown in Figure 1 and Figure 2, the former reset button of manual pull station 3 and the button that can play the intercommunication effect are combined into an intercommunication reset button 4, circuit board 5 realizes that with loud speaker 1 circuit is connected with pick-up 2 respectively.The conversation hole of pick-up 2 and the hole pattern of loud speaker 1 all are exposed on the panel of manual pull station 3.Intercommunication reset button 4 and projection 8 interlocks that are positioned at its back lower place, projection 8 is supported by spring.Projection 8 cooperates with the contact 7 of switch 6 again.
During use, only need intercommunication reset button 4 is pressed,, make pick-up 2 and loud speaker 1 and circuit board 5 conductings by the contact 7 of projection 8 depress switch 6, this moment manual pull station 3 just and the closing of the circuit of fire watch chamber, can realize intercommunication function by pick-up 2 and 1 of loud speaker.
When pushing for emergency sheet 9 when the condition of a fire occurring, the lower end of alarm 9 also can drive projection 8 motion and the contact 7 of compressing switch 6 makes circuit board 5 conductings, can realize intercommunication function equally.
