DVST Installation Guide

Operation

3Operation

3.1Callback

The callback feature allows an operator at a monitoring station to call a DFT0100 transmitter on site and configure the unit to automatically call them back, ensuring that the telephone call is charged to the transmitting and not the receiving site.

On sending a callback request, the monitoring station disconnects and waits for the transmitting site to call back. With callback enabled, connection time is approximately twice that of normal connection time.

3.2Alarms Feature

The alarm system for the DFT0150 transmitter allows the unit to freeze the pictures from cameras that correspond with the alarm inputs that have been triggered. These pictures are then transmitted to a receiving station where they can be acknowledged and the relevant action taken.

On an alarm the transmitter will automatically call the telephone number stored in telephone entry 0.

If this number is busy then it will call the number stored in telephone entry 1. The maximum number of telephone entries can be set between 1 and 16.

If the fall back numbers are busy the transmitter will automatically keep calling between telephone entries 0 and 1 until one becomes free. However the user can configure the DFT0150 to automatically call upto four numbers unitl one becomes free.

Depending on how the transmitter has been configured, incoming alarms are handled in different ways.

DVST, DFT 150/175 specifications

Guardian Technologies has made significant strides in the air purification industry with its innovative DFT 150 and DFT 175 models, designed to enhance indoor air quality for both residential and commercial spaces. These advanced devices leverage cutting-edge technology to deliver clean, fresh air, addressing the increasing need for effective air purification solutions.

One of the standout features of the DFT series is its multi-stage filtration system. Both the DFT 150 and DFT 175 are equipped with a pre-filter that captures large particles, such as dust and hair, followed by a true HEPA filter. This HEPA filter is capable of capturing 99.97% of airborne pollutants as small as 0.3 microns, including allergens, mold spores, and pet dander. This is an essential feature for individuals suffering from allergies or respiratory issues, ensuring that the air they breathe is significantly cleaner.

In addition to the HEPA filtration, Guardian Technologies has incorporated a UV-C light that works in tandem with the filter system. This technology helps to kill airborne bacteria and viruses, providing an extra layer of protection against pathogens, which is particularly crucial in today’s health-conscious environment.

Another characteristic that sets the DFT 150 and 175 apart is their energy efficiency. Both models are designed to operate quietly and consume minimal energy, making them suitable for continuous use in bedrooms, living rooms, or offices without causing a spike in electricity bills. The DFT 175 model features an added air quality sensor, which monitors and adjusts the fan speed automatically based on the detected air quality, ensuring optimal performance without unnecessary energy expenditure.

The sleek, modern design of the DFT series ensures they blend seamlessly into any decor. With portable options, users can easily move these units from one room to another, providing flexibility in air purification.

Moreover, the DFT models come equipped with easy-to-replace filter indicators, notifying users when it’s time to replace the filters. This convenience promotes consistent air quality management without the hassle of manual reminders.

In conclusion, Guardian Technologies' DFT 150 and DFT 175 models represent an excellent investment for anyone looking to improve indoor air quality. Their sophisticated filtration technology, additional UV-C features, energy efficiency, and user-friendly design make them a top choice for air purifiers in the market today.
