Function and purpose

The VT460 is a versatile sensor that combines smoke, humidity, and temperature monitoring in a single unit. It features high smoke sensitivity, allowing it to detect even low concentrations of smoke, making it an essential tool for early fire detection in critical environments. Additionally, the VT460 provides precise measurement of temperature and humidity, ensuring comprehensive environmental monitoring. This multi-functional sensor is ideal for data centers, server rooms, and other facilities where reliable environmental and safety monitoring is crucial.

A separate element inside the web interface represents every environmental parameter of VT460. This allows us to set individual thresholds and set up event triggering such as notifications and other actions.

CAN devices and sensors can be chained together. Up to 10-32 CAN devices can be connected in a chain. You can connect CAN sensors or extensions on a CAN bus line.

Use cases

These use cases demonstrate the versatility of the VT460 in various sectors, providing enhanced monitoring and control capabilities to improve operational efficiency and security.

1. Fire Safety Monitoring: The VT460 can be integrated into fire alarm systems to provide real-time monitoring of smoke levels in various environments, such as commercial buildings, warehouses, and manufacturing facilities. Its ability to detect smoke quickly can trigger alarms and alerts, ensuring prompt responses to potential fire hazards.

2. Data Centers: In data centers where high-value equipment is housed, the VT460 can monitor for smoke and heat, which are critical indicators of fire risks. Early detection helps to protect equipment and reduce potential downtime due to fire-related incidents.

3. Residential Applications: Homeowners can utilize the VT460 as part of a smart home system to monitor smoke levels in kitchens, attics, or near heating systems. Notifications can be sent to mobile devices, allowing for immediate action in case of a fire.

4. Industrial Facilities: In factories and processing plants, the VT460 can monitor smoke emissions from machinery or during production processes. This application helps ensure compliance with safety regulations and environmental standards.

5. HVAC Integration: The VT460 can be connected to HVAC systems to monitor air quality and detect smoke, allowing the system to respond appropriately, such as by shutting down air circulation in case of smoke detection, thus preventing the spread of smoke and fire.

6. Event Triggering for Emergency Protocols: In the event of smoke detection, the VT460 can trigger specific protocols, such as activating fire suppression systems, sending alerts to security personnel, or locking down certain areas to ensure safety.

7. Educational Institutions: Schools and universities can implement the VT460 in classrooms and common areas to enhance fire safety measures. It can monitor smoke levels and send alerts to administrators, ensuring a quick response in emergencies.

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;

4. Temperature & humidity sensor

5. 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.

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.
