The TC809C1004 Analog Input Module allows the XLS3000fire alarm control panel (FACP) to monitor industry-standard,linear-scale, 4-20 mA protocol sensors. The module converts the sensor output to a communication protocol that can be inter-pretend by the FACP for monitoring and display. There are numerous sensors available in the marketplace that communicate using a 4-20 mA output, including gas sensors, temperature sensors, airspeed sensors, and more.
The TC809C1004 Module includes numerous safeguards and protective features to ensure trouble-free operation. The external power supply is isolated from the communication line. In addition, a 500 mA current limiter and a cutoff circuit protect the module’s electrical supply from short circuits. In the event of a short, the output voltage will cycle within safe limits until the short is removed. The output signal is sampled and filtered for transients and noise prior to passing the signal along to the FACP. If the current running through the sensing circuitry exceeds 25 mA, the output voltage will shut down and the short protection process will begin. The module accepts both3-wire (device sink) and 2-wire configurations. The XLS3000 panel with compatible firmware supports up to five programmable thresholds for each TC809C1004. The TC809C1004 Analog Input Module is rigorously designed and tested for electromagnetic compatibility and environmental reliability, in most cases exceeding industry standards. The device is equipped with a panel-controlled LED for local status indication. The standard SEMS terminals will accept wiring from 12 AWG to 18 AWG.
