Products that are marked "On Order" in the "Available Quantity" column are usually not in stock. Such products are available for purchase, however, due to their limited customer base, they usually have higher minimum quantities. DACPOL offers products that are not in stock for the following reasons: DACPOL currently has a large number of electronic components in stock and adds new products every day, however, tens of thousands of additional components and their various variants are available from our suppliers. Even though it is unreasonable to have all these products in stock due to the limited sales, we believe that it is in the best interest of our customers to make them available. Our goal is to inform customers about the maximum number of products available and enable them to make decisions based on specifications, prices, availability, required minimums and our technical advice. Please note that selecting the "In Stock" checkbox may limit the display to only products available for delivery straight from the shelf.

Optical duct smoke detector with service alarm and built-in control unit for duct installation, 24V

Uniguard has been developed to detect smoke in ventilation ducts and combines a smoke detector and an adaptor system where both tube and housing are specially designed for optimum airflow through the smoke detector. There is a built-in alarm relay to control fire-safety dampers, stop ventilation fans, or activate acoustic and optical alarms, etc. There is a built-in service alarm relay to let you know when maintenance is needed before a false alarm occurs. 

A smoke sensor/detector is a key device in all houses, apartments, workshops, and factories, in which there's a risk of uncontrolled smoke occurrence. 

Smoke detector - the principle of operation

The smoke sensor monitors air conditioning. In case of detecting danger, that is, a moment in which the norms of a given gas concentration are exceeded, the sensor signals the risk with a sound alarm. 

Smoke detectors should be managed in places where tee smoke can be quickly detected, thus should be placed on the ceiling, in the highest room point. They are not installed in well-ventilated rooms, and also outside the buildings.

Smoke detectors - types

  • Optical smoke sensor - sensor with high sensitivity, works immediately after detecting smoke. For work in closed rooms, where smoke, dust or steam does not normally occur. Based on infrared radiation.
  • Linear smoke detector -  in big surface rooms. Works based on intaking light through the smoke. 
  • Carbon monoxide sensor - in rooms constantly occupied by people. 
  • Ionizing smoke sensor - contains electrodes, between which there's an uninterrupted ion flow. The smoke interrupts the flow and the sensor is activated. 

Applications and functions of smoke sensors and alarm systems:

  • alarming about the fie, information about need for evacuation;
  • turning on sprinklers, turning off air conditioning, cutting off power;
  • informing the fire department.

Benefits of fire sensors: short reaction time, additional function in smoke detection systems.

Disadvantages: false alarms.
