Function and purpose

Smoke, humidity, and temperature sensor with high smoke sensitivity and precise temperature, and humidity measurement. The detector responds to the appearance of the smoke of the low concentration.

Version: 8.1

Physical description

From the picture above:

1. Operation LEDs:

• WHITE LED - the sensor is ready for operation, blinks every few seconds, Normal Mode;

• RED LED - alarm indication, Alarm Mode;

2. CAN bus ports (numeration does not matter, any port can be used for either side)

3. Configuration LEDs:

• Red LED - the sensor is connected to the system;

• Blue LED - the CAN configuration started;

3. Temperature & humidity sensor

4. Termination switch (Termination should be “ON” if the sensor is the last sensor in a CAN bus chain.)

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

• 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 sensor

Connect one end of the RJ11 / RJ12 cable to the monitoring unit CAN port and the other end to any CAN input of the smoke sensor. It is possible to connect up to 10 sensors to one CAN port. To do so connect a new RJ11 cable to a free input of an 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 starts, configure the CAN bus, after configuration, the LED on the smoke detector will blink dimly once a second. 

Now we need to switch TR to position OFF for all sensors except the last sensor. And switch TR to the OFF position for the last sensor.

Depending on the version of VT460, please choose the below picture to help you accomplish that.

Configure the sensor

In the current example, we will connect x2 VT460 sensors connected in a chain. Once connected, Configuration Red LEDs at the back of the sensors will light up.

After connecting the sensor to the CAN bus chain go to Vutlan Web Interface >> “CAN configuration” panel >> press “Configure” >> “Are you sure you want to start CAN configuration” press “Yes” >> you should see the following

Once the sensors are configured, they will appear in the window. Configuration Blue LED at the back of the sensors should light up.

You should see both VT460 sensors in the CAN configuration panel.

The Operation White LEDs at the front of the sensor will blink every few seconds. This means the sensor is ready for usage.

Testing the sensor

You can use PRF Alarm tester spray:

Spray PRF Alarm tester onto the sensor. The sensor will switch to Alarm mode and the Operation RED LED will light up on the front of the sensor.

After a while, depending on how much you sprayed, the sensor will automatically return to Normal mode.

False alarms

Avoid high-frequency noise and the impact of dust on the sensor, the noise and dust cause false alarms.

Technical specifications

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.
