Page 8: Chapter 3 Installation Instructions
Chapter 3 Installation Instructions 3.1 Selecting a Location Factors such as air movement, gas density in relation to air, emission sources and environmental variables affect correct sensor location. Air movement by fans, prevailing winds and convection should be carefully evaluated to determine if a leak is more likely to raise gas levels in certain areas within the facility. -
Page 9: Mounting The Enclosure
After you have determined the appropriate location for your gas detector, it is important to securely mount the gas detector using the predrilled mounting flanges on the enclosure (Figure1). Dimensions for the mounting holes can be found for both the aluminum and poly enclosures in Figure 2. Figure 1 SensePoint Mounting Dimensions UM-1096 Revision A... -

Page 11: Power And Analog Outputs Wiring
3.3.1 110-230VAC @15W Power Wiring The SensePoint is powered by a 110-230VAC @ 15Watt power supply. Which has a full range AC Input along with short circuit, overload, over voltage and over temperature protections. The SensePoint can be ordered with the optional 2.3M AC power cord for ease of wiring and installation. -
Page 12: Option Board Wiring
TB2.SHLD. Note that there are two sets of terminals labeled TB2.A and TB2. B. This allows you to connect multiple SensePoint gas detectors in series. Each SensePoint represents an RS-485 slave and must have a unique Remote ID address (slave address). It is also important to note that wiring should be daisy chained as opposed to a star pattern for reliable operation. -
Page 13: Sensepoint Relay Option
3.4.2 SensePoint Relay Option The SensePoint Relay option (Figure 5) includes three programmable relays and a single programmable RS 485 Modbus master or slave port. The relay labeled “FAILSAFE” is set up as a failsafe Fault relay by default but can be configured as a programmable relay in the Relay Settings menu. It is possible to use only the relays, only Modbus or both. -
Page 14: Remote Sensor Installation
3.5 Remote Sensor Installation 3.5.1 SensePoint Remote Sensor Use of the Remote Sensor Option Board requires the SensePoint to be equipped with a RS 485 Option or Relay Option Board. The Remote Sensor Option Board communicates to the SensePoint by utilizing one of the RS-485 communication ports located on the option board. -
Page 15: Sensor Installation And Replacement
3.6 Sensor Installation and Replacement The SensePoint utilizes RC Systems’ Gen II Smart Sensors. These sensors come factory installed and provide our highest level of performance with increased accuracy and signal to noise ratio. The 8- conductor Smart Sensor interface connector attaches to the J1 connector on the base board, and the detector detects the type of sensor automatically. -
Page 16: Chapter 4 General Operating Instructions
Alarm levels for Alarm 1, 2 and 3 are set to the desired value Note: SensePoint gas detectors have standard relays, which should also be set up at this time. When no relays are installed, alarms are indicated only by the display color. -
Page 17: Normal Operation
To cycle through the data display screens, use a magnet and swipe the Next key until the desired screen is reached. Figure 8 SensePoint Data Display Screens 4.4 Fault Condition The Fault alarm is used to indicate a condition when there is a failure from the sensor or an out of range state has been reached. -
Page 18: Alarm Conditions
4.5.1 SensePoint The SensePoint allows the user to select the color associated with a certain alarm level. Options include yellow, orange, red, blue and purple. Alarm 1 is always set to yellow, and the Fault alarm is always set to Red. -
Page 19: Chapter 5 Calibration Procedure
Calibration Procedure 5.1 Preparation Calibration is the most important function for ensuring correct operation of the SensePoint Series of gas detectors. The CAL MODE is designed to make calibration quick, easy and error free, and a successful Zero and Span calibration requires only four keystrokes. The 4-20mA output transmits 3mA during the calibration, and 4mA during calibration purge to prevent alarms. -
Page 20: Figure 11 Calibration Diagram
Figure 11 Calibration Diagram Prior to beginning your calibration make sure you have the following items: 1. A cylinder of calibration gas with concentration equal to the SPAN GAS VALUE setting (RC Systems typically recommends choosing a value at 50% of full scale.) 2. - Page 21 5.

Page 22: Routine Calibration Procedure
Use the following step-by-step procedure to perform Zero and Span calibrations (Figure 13 may be used for reference to the Menus.): Note: The first three steps must be performed before the timer expires, 15 seconds, otherwise the SensePoint will exit back to the Data Display Screen.

Page 23: Bump Test Procedure
5.3 Bump Test Procedure Note: A bump test, when performed correctly, is meant to check both sensor and alarm functionality. This results in expected alarms, and proper precautions should be taken. Also known as a functionality test, a bump test is not meant to test the accuracy of the detector, and no calibration settings are changed during the test. -
Page 24: Chapter 6 Maintenance Procedure
RC Systems recommends performing calibrations at regular intervals to ensure proper functionality of the SensePoint. During routine calibration, RC Systems recommends a visual inspection of sensor head, enclosure and conduit entries to check for cleanliness and physical integrity. Cleaning the detector is recommended when necessary but be aware that some cleaning compounds may be detected by an operational detector depending on the sensor type. -
