Safety instructions

• Please observe the valid regulations for installation in the country in which the smoke alarm is installed and operated, and the national regulations for accident prevention. Please also observe any internal company regulations, such as work, operating, and safety regulations.

• The technical specifications and limit values stated must not be exceeded under any circumstances. In particular, this applies to the specified ambient temperature range and IP protection category.

• If a higher IP protection category is required for a special application, the smoke alarm must be installed in an appropriate housing or an appropriate enclosure with the required IP protection category.

Siting location requirements

To ensure the proper functioning of the unit, the conditions for the installation site of the unit specified in section “Technical specifications” must be observed.

Electromagnetic interference

Interfering electrical installations (high frequency) should be avoided.

Installation procedure

Notes on assembly

• It is vital to ensure that the smoke alarm is always assembled with the sensor head pointing downwards. In any other position, there is no guarantee that smoke will be detected.

• The smoke alarm must also be positioned so that it is ventilated with an adequate amount of air and the ventilation slots are not covered.

Installation with the mounting plate provided

The smoke alarm is installed using the mounting plate provided.

• Uncover the smoke detector head from the base.

• Attach the smoke sensor base to the mounting plate using the M4 x 10 screws provided.

• Replace the sensor head onto the base and secure it by twisting it until it locks home.

• Secure the mounting plate to the enclosure frame using the 4.8 x 19 screws.

• Remove the red protective cap!

Connecting the smoke sensor

Connect one end of the RJ11 / RJ12 cable to the monitoring unit and the other end to any of the two inputs of the smoke sensor. It is possible to connect up to 10 sensors to one analog port. To do so connect the new RJ11 cable to a free input of the already connected smoke sensor and the other end to the next smoke sensor in a chain. See the picture below. RJ11 or RJ12 cable pinouts can be found in the picture below. After the system will start and sense the smoke detector, the LED on the smoke detector will blink dimly once a second.

Testing the smoke sensors

During system operation, take a needle or paper clip and insert it into the hole on the cover of the sensor, try to move it there until the blinking dimly LED will flash brightly. That means that sensor is in a good state. After inspection, return the sensor /s to a normal state. To do this, either disconnect them from the system, or in a system interface, go to the smoke sensors tab, and restart them.

Connecting analog sensors

Connect the analog sensor by a supplied RJ-11 (6P4C) cable to any analog port "A1 .. A8" or "Sensor" port. The determination of the sensor type and connection will occur automatically.

If strong electromagnetic interference is present, we recommend using a 3-pair cable CAN FTP for sensor connection!

Colors are true for this telephone cable. Both ends match the colors and pinouts (identical).

Please refer to the RJ connectors comparison table:

Daisy chain connection

Some of the analog sensors can be connected to a daisy chain. Please refer to the article "Chain Connection of analog sensors".

Analog sensor configuration

Settings tab

To configure a sensor, go to "Main menu" >> "System tree" and click on the sensor element in the tree. A modal window with sensor properties will pop up. Change the needed settings and click "OK" or "Apply" at the bottom of the "Properties" window.

All sensors include:

1	Name	The name is given by the system automatically. You can change it to anything you want.
3	ID	System ID of the element.
4	Type	Examples: temperature, humidity, vibration.
5	Class	Examples: analog, CAN, switch, discrete.
6	Hardware port	The external port number on the device panel to which the sensor is connected (if the sensor is external).

All sensors have threshold controls:

In the picture above, the "Current value" equals 41.0 and is represented by the small triangle. Currently, the triangle is green because it is situated in the "Normal" range. Hence the sensor says that the "Current state" is "Normal". This value is used by the system's "Logic schemes" menu to notify the administrator or take action.

Hysteresis

Sensors have the option of setting the hysteresis state. Hysteresis can be a time, a value or it can be disabled.

If the hysteresis is set in time, the sensor will transmit to a new state with a delay of the specified number of seconds in the corresponding field. The time counting will begin from the moment when the measured value of the sensor has left the current range.
Each state has its own field. Which determines the time that the sensor value must continuously hold for the state to change to the specified.

If you set the hysteresis by value, the sensor transition to a new state will occur when the measured value of the sensor exits beyond the current range, adjusted for the specified hysteresis value.

You can calibrate the sensors. Use K and B coefficients. After the calibration, please, save the values in flash memory.

To save sensor properties in the device's flash memory press "  "  then "OK" to confirm. 

Example: Why do we need to use Hysteresis

Let’s say that we have a temperature sensor. Let’s say that we have set up threshold values.

We have set the value 25.5 °C to be a threshold value between Normal/Alarm states.

If the temperature drops just below 25.5 °C You will have a “Normal” state.

If the temperature goes just above 25.5 °C You will have a “Warning” state.

Sometimes the temperature may stay at 25.5 °C and jump up and down by 0.1-0.3 °C. In this case, You will get too many notifications that the sensor is showing a Warning or Normal state.

In this case, we need to use a Hysteresis.

If the type “time” is chosen, the system will wait for a specified time before the State of the sensor is declared.

If type “value” is used, unless the temperature drops by a larger amount than specified, the sensor state will not be declared.

Tuning the sensor value

Sensor readings can be tunned by a linear formula "y = k * x - b"

Example VT407 + HAT-100Q1 / AC current converter:

Metered current for HAT: from 0 to 100A (This means that the range equals 100, k = 100)

The output of VT407 is 0-5V (That means that the range is equal to 5)

"b" = the value that the sensor shows in WebUI when there's no current. Let's say that b = + 0.021

You should use the following formula for HAT: 100/5*(x-y)

The expression formula would be 20*(x-0.021)

Point is used as a decimal separator (3.14)

Charts tab

The charts tab shows the following:

Display chart for	last 100 seconds last 100 minutes last 100 hours last 100 days
Refresh data	Start	Poll a sensor
Reset all charts	Reset all	Clears all saved data for the sensor.
Export data	XML or CSV	Exporting data through WebUI does not work for more than a couple of days and is very rough. If you need detailed log data, use the logging of sensor values to the media. Read more at: System Log, Sensors dump files. Note: Make sure no endpoint security services used in the network are not blocking the download of XML and CSV files.

• Example: Using fuel tanks.

Reset smoke sensors

If analog sensors like VT560 / Smoke detector/ sensor detects smoke or fire, it will go into Alarm mode. Alarm mode can only be switched off manually using the Reset smoke detectors panel or using the onboard sensor Analog sensor power reset is found in the System tree >> Onboard.
