Sensaphone Room Humidity Sensor with Display for IMS Systems Sensaphone room humidity sensor IMS-4821 with display connects to your existing IMS-4000 Host or Node or IMS-1000 via an RJ-45 jack. Because the sensor utilizes your existing Category-5 structured wiring system, no special wiring or schematics are needed to install them. Simply locate where you want to place the sensor, attach a standard patch cable, plug it into your patch panel and do the same in your server room to connect your sensor to the IMS-4000. Its no different than wiring up a workstation or a printer. Note FGD sensors, accessories, etc. are not compatible with IMS-4000 systems Once connected, the IMS-4000 system by Sensaphone automatically recognizes the sensor type installed and configures it for you, using a standard template that you can modify. Because the IMS-4000 supplies power and configuration data for each sensor, the IMS-4000 can detect faults with your sensors if theres a cable disruption or yoursensor is accidentally unplugged, youll know it.
