Abstract
The utility model discloses a starting module applied to an SDE fire extinguisher. The starting module applied to the SDE fire extinguisher comprises a starting relay and a feedback relay and is characterized by being provided with an early warning relay. The starting module applied to the SDE fire extinguisher has the beneficial effects that the two-relay isolation control is adopted, and an SDE gas fire extinguisher can be effectively prevented from being influenced by electromagnetic interferences.
Description
Technical field
The utility model relates to fire-fighting domain, is specifically related to a kind of startup module of the SDE of being applied to fire extinguisher.
Background technology
At present, that the startup circuit that is applied to SDE fire extinguisher has is mostly unshielded to electromagnetic interference, equipment malfunction is made the shortcoming that rate is high.
Summary of the invention
In order to address the deficiencies of the prior art, the utility model provides a kind of startup module of the SDE of being applied to fire extinguisher, adopts two-way relay isolated controlling, can effectively prevent that SDE extinction using gas fire extinguisher is subject to electromagnetic interference.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of startup module of the SDE of being applied to fire extinguisher, comprise starting relay, feedback relay, and it is characterized in that, described module is provided with early warning relay.
The beneficial effects of the utility model are: the utility model provides a kind of startup module of the SDE of being applied to fire extinguisher, adopt two-way relay isolated controlling, can effectively prevent that SDE extinction using gas fire extinguisher is subject to electromagnetic interference.
Brief description of the drawings
Fig. 1 is the functional-block diagram of a kind of startup module that is applied to SDE fire extinguisher described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of startup module that is applied to SDE fire extinguisher, comprise starting relay, feedback relay, it is characterized in that, described module is provided with early warning relay, for in advance the interior insurance of SDE fire extinguisher startup module being opened, make to start circuit in conducting state in fire alarm control unit delayed startup 30 seconds.Described in the time that fire alarm control unit enters delayed startup pattern, provide DC24V power supply to early warning relay.
More than to description of the present utility model and non-limiting, based on other embodiment of the utility model thought, also all among protection domain of the present utility model.
