TCFH-581K Fire Door Monitoring Interface  

* Monitor single door normally open fire doors * The circuit part and the wiring bottom case are plugged in for reliable contact and easy construction * The address code is electronically encoded and can be written in advance by the electronic encoder. The engineering debugging is simple and reliable * The microprocessor monitors the operation and transmits the status of the module to the monitoring host in both normal and fault modes. * Monitoring interface can detect any short circuit or open circuit happened on electric door closer, electromagnetic release device and magnetic switch * Wire system: It is connected to the monitoring host by a non-polarity signal two bus, and the power line is connected by a non-polar two-wire system * Dimensions: 86mm × 86mm × 38mm (with bottom case) With the improvement of economic level, all kinds of life factors in cities are constantly changing, and all kinds of situations with high risks and hidden dangers are constantly increasing.…
