| Technical specification | <p>Calectro duct smoke detector with display/Modbus 24 V AC/DC, DIBt<br>The DIBT-Approved UG8 Uniguard is a specially developed sewer smoke detector for reliable<br>Detection of smoke in ventilation ducts. It combines a high-quality smoke detector with a<br>Flow-optimized housing that enables precise detection. In Conjunction with the Air Guide Profile<br>PST195 ensures effective smoke detection without recording the entire channel cross-section<br>Must</p><p>• “AL” — smoke alarm<br>• “LF” — low flow alarm<br>• “--” — System fault or detector removed<br>The UG8-ZD-24 has a Modbus RTU interface (read-only), which has the following values<br>The following can be read out:<br>• Smoke detector status<br>• Current level of contamination<br>• Low airflow alarm<br>The communication settings are configured using the control button on the right of the display.<br>Supply voltage: 24V AC/DC ± 10% Non-polarity sensitive<br>The UG8 can be flexibly mounted on either side of the ventilation duct. The installation is carried out with a<br>Assembly device which is attached to the channel together with the selected air guide profile or venturi tube.<br>The PST195 pipe can be used from a channel diameter of 200 mm without an additional mounting bracket<br>Be used.<br>For easy and correct installation, the UG8 has a “FLOW” arrow that shows the direction of airflow<br>Pretends in the channel. This must match the actual flow direction.<br>The detector's innovative, patent-pending housing offers integrated cable entries and a<br>Reset button and can be flexibly adjusted to optimally adapt to installation conditions.<br>Thanks to practical snap locks, the duct smoke detector can be opened and closed without tools.<br>The UG8-ZD-24 duct smoke detector is equipped with an integrated display that<br>Shows the level of contamination of the detector as a percentage. When the maintenance or<br>Contamination alarm, the message “SA” (Service Alarm) is output instead of the percentage value.<br>Display ads:</p><p>Detector type: Optical EVC-PR-DA<br>Maximum power consumption: 85mA (DC), 235mA (AC)<br>Modbus communication: RS485<br>Operating temperature: -20°C to +55°C<br>Humidity: Max 95% RH<br>Duct air velocity range: 1 to 20 m/s<br>Approvals: CE, VdS G224038, DIBt Z-78.6-253, EN-54-27<br>Relay outputs: potential-free<br>Smoke detector relay: 1 250V, 8A changeover relay and 1 250V, 8A interruption relay<br>Maintenance and air speed alarm: 1 interruption relay 250V, 1A<br>Alarm in case of system failure: 1 250V, 1A interruption relay<br>LED on smoke detector:<br>Yellow - pollution alarm<br>red - smoke alarm<br>LED on the circuit board:<br>Green - normal mode<br>Flashing yellow - system error<br>Yellow - airflow alert<br>Case: PC/ABS<br>Venturi tube: PC/ABS or aluminum<br>Protection class: IP65<br>Cable openings: 2 x Klickseal<br>Air sampling pipe: PST195 tested and approved for all channel cross-sections (included<br>included) opening diameter 38 mm.</p> |
