Problems solved by technology
However, there are currently two alarm circuits in the market: one is the switching value alarm input application circuit, and the other is the voltage detection alarm input application circuit; and these two alarm circuits cannot be used at the same time, and customers can only choose one of them. If the customer builds an alarm platform and buys new equipment for the user, the user can purchase a unified alarm output device in batches, but if the customer is to upgrade the original equipment, it will cost a lot of money. Unified alarm output equipment, the replacement of this type of alarm output equipment will no longer be of any use to the customer, resulting in a serious waste of manpower and financial resources

In particular, the invention relates to an inventive circuit supporting composite signal alarm input applications. Realize self-adaptive docking with different types of alarm devices on one interface. The invention creatively connects different alarm devices of different customers to the alarm platform at the same time, avoiding the cost of replacing the same device that outputs the alarm signal when the customer needs a unified alarm mode, and saving a lot of manpower and financial costs for the customer.
Description
(1) Technical field [0001] The invention relates to a networked alarm system in the field of security protection, in particular to a circuit supporting the application of composite signal alarm input. (2) Background technology [0002] In the actual application of networked alarms, there are two types of externally connected alarm output devices, one is switch type: supports normally open and normally closed mode, and the other is output voltage type. If you need to connect these two devices, the latter The terminal equipment detection and alarm input interface must support both switch type equipment and output voltage type equipment. When the back-end detection circuit equipment detects the input signal, it can adaptively select whether it is a light quantity signal or a voltage detection signal. However, there are currently two alarm circuits in the market: one is the switching value alarm input application circuit, and the other is the voltage detection alarm input applic...
