Calectro duct smoke detector with display/Modbus 24 V AC/DC, DIBt
The DIBT-Approved UG8 Uniguard is a specially developed sewer smoke detector for reliable
Detection of smoke in ventilation ducts. It combines a high-quality smoke detector with a
Flow-optimized housing that enables precise detection. In Conjunction with the Air Guide Profile
PST195 ensures effective smoke detection without recording the entire channel cross-section
Must • “AL” — smoke alarm
• “LF” — low flow alarm
• “--” — System fault or detector removed
The UG8-ZD-24 has a Modbus RTU interface (read-only), which has the following values
The following can be read out:
• Smoke detector status
• Current level of contamination
• Low airflow alarm
The communication settings are configured using the control button on the right of the display.
Supply voltage: 24V AC/DC ± 10% Non-polarity sensitive
The UG8 can be flexibly mounted on either side of the ventilation duct. The installation is carried out with a
Assembly device which is attached to the channel together with the selected air guide profile or venturi tube.
The PST195 pipe can be used from a channel diameter of 200 mm without an additional mounting bracket
Be used.
For easy and correct installation, the UG8 has a “FLOW” arrow that shows the direction of airflow
Pretends in the channel. This must match the actual flow direction.
The detector's innovative, patent-pending housing offers integrated cable entries and a
Reset button and can be flexibly adjusted to optimally adapt to installation conditions.
Thanks to practical snap locks, the duct smoke detector can be opened and closed without tools.
The UG8-ZD-24 duct smoke detector is equipped with an integrated display that
Shows the level of contamination of the detector as a percentage. When the maintenance or
Contamination alarm, the message “SA” (Service Alarm) is output instead of the percentage value.
