Job Checkin

Deficiency: The duct detector on RTU 1 does not trip and needs to be replaced. Checked it for proper wiring. The only way to get it to trip the panel is to short the wiring. The System Sensor RTS has power, 27v from the dd but has no led lit up and, does not work. This should also be replaced. I tested another random RTS and it functioned properly. Compared wiring from the switch to dd circuit board for RTU 1 and RTU 2 and, it is the same. Models are: Duct detector: System Sensor D4120 RTS: RTS2-AOS
