1. Compatibility of communication protocols
The communication protocol between the Fire Alarm System Motherboard and the detector is one of the key factors of compatibility. Different types of detectors, such as smoke detectors, temperature detectors, flame detectors, etc., may use different communication protocols, such as 485 bus protocol, CAN bus protocol or wireless communication protocol (such as Zigbee, Bluetooth, etc.). The motherboard needs to support multiple standard communication protocols, or have scalability, and be compatible with new protocols through software upgrades or adding communication modules. For example, some advanced motherboards use universal interfaces and adaptive communication protocol parsing technology. When connecting a new type of detector, the motherboard can automatically identify and adapt its communication protocol, thereby achieving seamless connection.
2. Matching of signal types and parameters
The signal type and parameter range output by the detector also need to match the motherboard. Smoke detectors may output analog voltage signals or digital signals, and their signal strength and change rules are different from those of temperature detectors. The motherboard must be able to accurately receive and identify these different types of signals. For example, for analog signals, the motherboard needs to have a high-precision analog-to-digital conversion circuit to convert the continuous analog signal from the detector into a digital signal for processing. At the same time, the motherboard also needs to have appropriate threshold settings for signal parameters. For example, the smoke concentration signal reaches a certain threshold to trigger the alarm. This threshold should be able to be flexibly adjusted according to the characteristics of different detectors to ensure compatibility and accuracy.
3. Adaptation of electrical characteristics
It is also important to adapt the electrical characteristics of the detector and the motherboard. This includes aspects such as operating voltage, current consumption, and electrical interface for signal transmission. Different detectors may have different operating voltage requirements. The motherboard needs to be able to provide corresponding voltage output or have a suitable power conversion circuit to meet the power supply needs of the detector. In terms of current consumption, the power supply capacity of the motherboard should be sufficient to support the connection of multiple detectors to work simultaneously to avoid insufficient power supply. In addition, the type of electrical interface (such as plug-in interface, terminal block, etc.) and pin definition should match each other to ensure that the detector and the motherboard can correctly transmit signals and make electrical connections.
4. Software compatibility and scalability
The software of the Fire Alarm System Motherboard also plays an important role in compatibility. The software should be able to identify the device number, model and other information of different types of detectors, and be able to configure accordingly according to the function of the detector. For example, for detectors with different sensitivity levels, the mainboard software can allow users to set them according to actual needs through the configuration interface. At the same time, the software should have good scalability. With the emergence of new detectors and the development of fire protection technology, it can be easily updated and upgraded to add support for new detector types, such as data analysis and processing functions for new intelligent detectors, thereby improving the compatibility and adaptability of the entire fire alarm system.
