Figure 1-1 illustrates the Comfort/Vivid Sensor functional variants. Both variants share the same external dimensions (42mm x 42mm x 17mm).

Physical Interfaces
Figure 1-2 illustrates the customer-accessible interfaces for the Comfort/Vivid Sensor. All models share the same layout, though only functional interfaces are exposed in the case of each model. For example, a Base model has been shown in Figure 1-2, which does not have the PIR element (the PIR transducer indicated in the figure is the location for the actual PIR transducer in the PIR variant). Also, the PIR variant does not have an External Connector. Not shown in Figure 1-2, the Base variant has two internal moisture probes for moisture (leak) detection. The PIR variant does not have these probes and does not offer moisture detection.

Installation

Included Product and Installation Material
The following items are included with each sensor:

• Comfort/Vivid Sensor
• Mounting Bracket Kit
  NOTE: to ensure safe installation and maintenance, please read Safety Precautions.

Unpacking and Inspection
The following should be considered during the unpacking of a new Comfort/Vivid Sensor:

1. Inspect the shipping carton and report any significant damage to TEKTELIC.
2. Unpacking should be conducted in a clean and dry location.
3. Do not discard the shipping box or inserts as they will be required if a unit is returned for repair or re-configuration.

Commissioning
Each sensor has a set of commissioning information that must be entered into the network server for the sensor to be able to join the network and begin normal operation once activated. For instructions on how to do this please refer to the Network Server Quick Start Guide you get in the box with the device (also available online in the Knowledge Base).
You can find the commissioning keys inside the box. If you don’t have the box, raise a ticket in our support portal and provide the Tcode and serial number on the tag placed on the device.

Power Up/Down Procedure
Once the sensor information has been added to the Network Server, pull out the battery tab to engage the battery.

To turn off the device remove the battery, but to simply reset the device, the external reset button can be pushed. Refer to Section Battery Replacement for instructions on battery removal.

Default Configuration
The default configurations of Sensors are:

Reconfiguration
The Comfort/Vivid Sensors support a full range of OTA configuration options. Specific technical details are available in the corresponding TRM document. All configuration commands need to
be sent OTA during the sensor’s DL Rx windows.

Comfort/Vivid Sensor Mounting
Comfort/Vivid Sensor is designed to be mounted using the supplied mounting bracket. The bracket can be attached using screws (not included) or double- sided tape (included).

External Connector Cable Installation
The Comfort/Vivid Sensor with external connection installation requires connection to an external device through the 2-pin connector on the top of the sensor.
Figure 2-3 shows the external connector pinout. In the digital mode, the connector can be attached to an open-drain output; however, the signal line can also be driven with digital signals at 1.8 V logic levels. In the analog mode, the two pins of the External Connector are polarity agnostic and are connected to a thermistor.

In the digital or analog mode, the connection cable MUST be routed through a cable clip shown in Figure 2-4. The cable clip is not provided with the module. The clip Essentra MWSB-1-01A-RT is recommended for this usage. Routing the connected external cable through the cable clip leads to the best EMI performance of the Sensor. The cable length in any mode MUST NOT exceed 3 meters. Also, ensure that the cable connection is not routed outdoors.

LED Behaviour
See Figure 2-5 for the location of the sensor LEDs described in Table 2-2.

 Operation, Alarms, and Management

Temperature and Relative Humidity Transducer
The Comfort/Vivid contains a temperature and relative humidity (RH) transducer. Vents on the enclosure allow air to contact the transducer. Response time can be reduced by forcing air to move over the vent as in Figure 3-1.

The Comfort/Vivid support reports ambient temperature, MCU temperature, and RH values on a user-defined threshold basis. Alarm points can be set individually for ambient temperature, RH, and MCU temperature. The frequency of measurements is user-configurable with different sample rates if the measured value is within the normal operating window (see Section 2.5).

Acceleration Transducer
The Comfort/Vivid features a 6-axis accelerometer for acceleration sensing, which can be turned off to save power. It supports two interrupt-based accelerometer events, both with configurable thresholds:

1. Acceleration Event: Triggered by exceeding an acceleration threshold. The accelerometer is disabled for a set debounce time to prevent multiple reports for a single event.
2. Impact Alarm Event : Activated when an impact alarm threshold is surpassed a configurable number of times within a set period. The alarm clears after a grace period with no impact.

Both acceleration and impact alarm functions can be toggled independently.

• Accelerometer readings can be in X-Y-Z vector or magnitude form.
• Axes (X, Y, Z) can be enabled or disabled independently; disabled axes output zero.
• The sampling rate is adjustable (possible options: 1 Hz, 10 Hz, 25 Hz, 50 Hz, 100 Hz, 200 Hz, or 400 Hz). Higher rates detect shorter events but drain the battery faster. The default is 1 Hz.

NOTE : Higher sample rates enable the detection of shorter acceleration events but consume more battery power.

Ambient Light Transducer
The Comfort/Vivid Sensor models feature an ambient light sensor located on the top surface, measuring light intensity through a light pipe.

Ambient light sensors can report both light intensity (periodically) and light status (dark or bright) based on a configurable threshold:

• Light Measurement: Sensitive to human visible light, peak sensitivity at 550 nm. Sensing range: 5 lux to 1000 lux.
• Threshold Adjustment: The light threshold is adjustable from 1 to 63. If the light status (dark/bright) doesn’t match the detected intensity, an event is reported. This event reporting can be enabled or disabled.

NOTE: Higher sample rates increase battery consumption. Testing is required to determine the optimal trigger point for the application.

Motion Detection (PIR) Transducer

• The Vivid Sensor PIR model contains a Motion Detector. The Motion Detection Transducer contains PIR elements and is configured to sense human motion within its field of view (FoV).
• The transducer has three available options of Fresnel lenses described in Table 3-1.

Table 3-1: Vivid Sensor Lens Options

Wide range lens ceiling mount provides the widest sense range for a ceiling height of 2.7 m in a rectangular area of 5 m x 4 m.

NOTE: Avoid exposing the PIR lens to strong UV light such as direct sunlight. Do not paint the surface of the lens or attempt to clean it. Any deformation of the lens will distort the sense pattern.
To be most effective at detecting motion, the subject must move across sensor element beams. The Vivid Sensor should be mounted so that the subjects move across its FoV and not towards or away from the Sensor.

Magnetic Switch
The Comfort/Vivid sensors contain a magnetic switch. The location of the switch is shown in Figure 3-3.

The Comfort/Vivid Sensor can be configured to activate based on the state of this switch and to report after a user-configurable count of switch events. To activate the switch, a magnetic field of about 10 gauss (1 milli-tesla) must be applied to the edge of the Sensor.

NOTE : A magnet required to activate the switch is not provided in the box. Standex-Meder M4, M5, or M13 magnets are suggested but any magnet of sufficient strength can be used.

The switch function can be configured to sense open-to-close events, close-to- open events, or both types of events. For example, if the Sensor is being used for sensing access to a door and is set to read both event types, it will record an event each time the door is opened and each time it is closed. The reporting of these events can be set by the customer to report after several events have occurred. If it is set to 0, no events are reported. If it is set to 1, it reports after each event.2

External Connection
The Comfort contains an External Connector, which has two modes, digital and analog. In the digital mode, the internal, control, and reporting interfaces of the External Connector are similar to but independent from, the Magnetic Switch in the Base model. See Section 2.5 for a description of the event function configuration and reporting count feature, which are similar to those of External Connector.

In the digital mode, the External Connector electrical interface is designed to be connected to an open-drain output; however, the signal line can also be driven with digital signals at 1.8 V logic levels.
In the analog mode, the External Connector is connected to a 10-kΩ thermistor (recommended CWF3AA103G3380 or NTCAIMME3) for remote temperature sensing. The Sensor in this mode of the External Connector reports voltages in mV, which can then be converted to temperatures. The conversion formula (voltage to temperature) can be obtained in one of the following ways:

1. Calibrating Thermistor and Performing Curve Fitting:
   Several voltage-temperature pairs can be obtained for a given thermistor, then the following curve-fitting formula can be used:

where T is in °C and V is in mV, and where B is the B-value of the thermistor (e.g. 3380 K for CWF3AA103G3380 or 3984 K for NTCAIMME3), to obtain the best a and b based on a desired criterion, e.g. MMSE (minimum mean square error) or minimax criterion.

For example, for CWF3AA103G3380 and NTCAIMME3, using the MMSE criterion, the conversion formulas are obtained, respectively.

Quick and Approximate Conversion Formula:
Another easier, though less accurate, way to quickly characterize any NTC (negative temperature coefficient) thermistor is to use the following conversion formula:

Steinhart–Hart Equation:
In this method,, the temperature of the thermistor, in K, is given as:

where ?0 is the reference resistance, in kΩ, of the thermistor (e.g. 10 kΩ), and where R is the thermistor resistance at temperature T, which can be obtained as

where V is the reported voltage from the sensor in mV.
Coefficients A, B, C, and D are usually given by the thermistor manufacturer. If not given, the coefficients can be determined by measuring 4 voltage- temperature pairs from the thermistor and forming 4 linear equations with 4 unknowns (i.e. A, B, C, D).

The physical connector and its mating connector of the External Connector are listed in Table 3-2. The Comfort/Vivid Sensor is not supplied with an external connection jumper cable. The link in Table 3-2 is a suggested cable. It is the customer’s responsibility to modify the cable harness for their application.

Should an external cable be connected to the External Connector, the external cable MUST be routed through a cable clip, characterized in Section 2.8, and the cable length MUST NOT exceed 3 meters. See Section 2.8 for the connector pin assignment and cable installation.

Table 3-2: Comfort/Vivid Sensor Interface Connector Types

Interface              Sensor Connector| Mating Jumper Cable (300mm)
---|---
External Connector| JST B2B-ZR(LF)(SN)| JST A02ZR02ZR28H305B

Moisture Detection Transducer
The Comfort model contains a Moisture Detector. The Moisture Detection Transducer is built into the bottom surface of the device (screw side). The moisture is detected once the bottom surface gets moist. The transducer is sensitive material in the sensing region so the trigger set point for reporting the presence of water must be calibrated for each application. This transducer can also be used to sense liquids other than water or skin. The customer must evaluate each application and configure the trigger point as required.

A calibration command can be sent to the Sensor to set a “dry” condition. The alarm point can also be set directly as a value. The sample period for moisture detection can be set to one of 4 values: 16, 32, 64, or 128 seconds. Smaller sample periods (faster sampling) use more energy and shorten battery life. The default sample period is 32 seconds.

Battery Replacement

The Comfort/Vivid Sensor is powered by a standard CR2477 coin cell.

Warning

• The Kona Comfort/Vivid Sensor contains a coin cell battery.
• Do not ingest battery, Chemical Burn Hazard.
• If a battery is swallowed, it can cause severe internal burns in just 2 hours and can lead to death.
• Keep new and used batteries away from children.
• If the battery compartment does not close securely, stop using the product and keep it away from children.
• If you think batteries might have been swallowed or placed inside any part of the body, seek immediate medical attention.

Use only approved CR2477 cells when replacing the battery. The following are approved replacement cells:

• Panasonic (model CR2477)
• Sony (model CR2477)
• EVE Energy (model CR2477)
• Jauch (model CR2477)

To access the battery, remove the two screws securing the case. The screws are accessible on the bottom of the sensor case and require a Phillips screwdriver PH1:

• Remove the two screws on the bottom of the case.
• While holding the sensor with the bottom facing up, remove the bottom of the case by gently prying the case apart.
• With the bottom removed, the coin cell holder is accessible.
• Remove the coin cell from the holder by gently pushing the cell a little outwards (e.g. by a small screwdriver), then taking the cell from the other end and pulling it out as indicated in the image below:
• Place the new cell in the holder. The top of the coin cell is marked with a + symbol indicating the positive terminal. This positive terminal must face up when replacing the cell. Push the cell into the holder until it hits the closed end of the holder.
• Check for LED activity. If the LEDs are lit, the battery replacement was successful.
• Replace the sensor cover and insert the two screws.

Basic Downlinks

• COMFORT/VIVID uses a “tick” system for reporting data. Generally, the sensor will report the most important data for every tick. A tick can be measured in seconds.
• Two sets of settings must be configured in conjunction – “Core reporting tick in seconds” and “Ticks per [data/report]”.
• “Core reporting tick in seconds” will determine the interval between ticks. For example, you may set it to 60 seconds or 180 seconds (3 minutes) for each tick.
• “Ticks per [data/report]” determines how many ticks it will take before the sensor reports any data. For example, if you set “Ticks per Battery report” to 2, it will take 2 ticks before the sensor reports battery data.

To Change The Core Report To Every Minute
With the LeapX application (you can get it on Google Play or App Store): write number 1 in the field minutes between reports, then click on save changes.

With ATLAS: check the box for Core report tick in seconds and ticks between ambient temperature reports. Write the values shown in the Figure 5-3 and click send.
