The Plus-X EM series brings extensive environmental monitoring and control capabilities to the ARC Plus remote control system. Plus-X EM units can be located where needed in transmitter sites and rack rooms with convenient Ethernet / IP connectivity to the ARC Plus control unit.
Protect your Equipment and Data
Environmental problems at remote sites can cause costly downtime, damage expensive equipment, and even lead to loss of mission-critical data. HVAC equipment failure, power outages, and simple human error can cause catastrophic problems—especially when running unattended. Broadcast equipment requires comprehensive monitoring of environmental conditions to detect a problem as early as possible.
The Plus-X EM series monitors temperature, humidity, flood/leak, and many other conditions that can cause serious problems. Email, SMS and SNMP notifications ensure that responsible personnel can respond quickly and effectively.
Watch for Early Warning Signs
Not all problems happen suddenly. A change in how equipment behaves over time may be an early warning sign of a serious problem. A gradual rise in temperature or a change in sound level may be evidence of impending equipment failure. Onboard charting allows you to watch for changes in environmental conditions over time, preventing a problem from becoming a crisis.
A Monitoring Solution that Grows with your Needs
The Plus-X EM series’ unique modular design allows you to add capacity and features as you need them. Easily add new sensors as you add equipment, and take advantage of new functionality when you need it.
Plus-X EM 64 can support up to a total of 64 sensors, including 3 built-in sensors, 8 switch inputs connected to the real panel connector, 8 powered switch inputs and up to 45 digital sensors connected in daisy-chain configuration to the front panel sensor ports. One or two optional modules can be installed in the front of the Plus-X 64 unit to simplify daisy-chain wiring and/or to increase the number of switch inputs or powered switch inputs, up to an overall total of 64 sensors.
Plus-X 32 is a convenient package providing up to a total of 32 sensors including 3 built-in sensors, 8 powered switch inputs and up to 21 digital sensors connected in daisy-chain configuration to the front panel sensor ports.

Part #: TEMP-INDOOR
The TEMP-INDOOR Sensor is a general-purpose, digital, indoor temperature sensor tailored for monitoring ambient temperatures within a room or in an equipment rack. Cables are not supplied with this sensor — order 25’ RJ-12 cable, part number SENSOR CABLE.
Part #: TEMP-WALLMOUNT
The TEMP-WALLMOUNT Sensor is housed in a 2 5/8” x 5” enclosure with air vents to facilitate sensing of the environment.14’ of cable is provided with an RJ-12 connector on one end. The TEMP-INDOOR has a large, easy to connect barrier strip that accommodates flat or Phillips type screwdrivers
Part #: TEMP-OUTDOOR
The TEMP-OUTDOOR digital outdoor temperature sensor is included with the BTU‐4D/BTU-4D-I systems, and is intended for general purpose monitoring of equipment or ambient temperatures. The TEMP-OUTDOOR sensor is attached to 25’ of cable with an RJ-12 connector on the end. The sensor has a mounting ring and gasket to accommodate #6 or #8 hardware. The sensing elements are sealed for added protection from dirt and moisture.
Part #: TEMP-STACK
