ESP Safety’s Model UPES Multi-Channel Controller offers maximum flexibility to users as a standalone, independent control system that can also be interfaced to a PLC or DCS system. This advanced microprocessor-based monitoring system is compatible with all
flame-detection and gas-sensor products offered by ESP Safety. Utilizing the analog outputs, 16 of ESP's detectors and sensors can operate in any combination. Utilizing the digital outputs, 128 of ESP's detectors and sensors can operate in any combination.
The UPES can be used at any facility for monitoring and detecting gas concentrations and flame and fire conditions. After being programmed with the desired thresholds, the UPES system will transmit light (LED) and sound alarms as well as signals to responding devices,
such as warning systems, automatic sprinkler systems, ventilation systems, and emergency shutdown controls.
The UPES is built on a standardized housing 3Ux19 inches (482x266x132
mm) based on a highway-module concept. The UPES contains the power supply module and the controller module. It has internal rack space capable of holding eight channel cards for up to 16 analog or 128 digital signaling devices. The UPES control panel can display up to three separate alarm levels per signaling device.

The network illustrated below, consisting of a UPES Multi-Channel Controller, SGOES and SSS-903 Gas Detectors, has the capacity to monitor potentially hazardous areas in proximity to oil and gas transit stations, gas and oil trunk pipelines, oil and gas storage tank farms, loading racks and similar facilities. When a lower explosive level (LEL) of gas presence (measured as a percent) has reached a preconfigured value, the UPES sounds an audible alert and sends alert signals to the control room monitoring devices while alerting operators. In addition, the UPES can send alert signals to facility level protection systems to initiate responses. These can include activating emergency facility shutdown, and automated ventilation system response.
