- Page 2 A SUBSTITUTE FOR OPEN AREA DETECTOR PROTECTION as a means of providing life safety. Nor are they a substitute for early warning in a building’s regular fire detection system. Calectro AB supports this position and strongly recommends that the user read NFPA Standards 90A, 72, and 101. UG-7-A6O is listed per UL 268A.
- Page 3 The UG-7-A6O has two versions that operates with 24 VDC/VAC or 120 VAC. The UG-7-A6O-24V for the 24 VDC/VAC and the Model UG-7-A6O-120V for the 120 VAC versions. Alarm and supervisory relay contacts are accessible to interface with control panel, HVAC control, and multiple auxiliary functions including turning off the fan.
- Page 4 Figure 2 Mounting position Ventilation duct Air flow direction We recommend that the UG-7-A6O is mounted on a distance of approximately 3 times the duct diameter before an obstruction such as dampers, filters or bends, and approximately 5 times the diameter after these obstructions as shown in Figure 3.
- Page 5 Figure 6 Figure 7 Figure 8 [5.4] INSTALLATION OF SAMPLING TUBE LONGER THAN 2 FT. Strong vibrations can arise inside a duct due to the air currents. When the diameter of the duct is larger than 2 ft. the sampling tube should penetrate the whole duct. Drill a 2 inch hole in the opposite side of the duct. Mount the rubber gasket HFU204* in the hole.

- Page 7 Connect power source to appropriate terminals of each detector. Power supply must not be connected to GND (terminal 1). NOTE 2: 120VAC Power Inputs accept 110-120VAC 50-60Hz (UG-7-A6O-120V). Connect power source to appropriate terminals of each detector. See specifications for additional power supply information.
