    The Safe-T-Alert Combo Carbon Monoxide ...

    The Safe-T-Alert Combo Carbon Monoxide Propane Alarm Surface Mount Black 25-742-BL that was installed in our camper had reached it s end of life and started beeping. We had a hard time at first finding the exact replacement on Amazon so i checked Ebay. Luckily we found the one we needed. It arrived quickly and was easy to replace. After the initial set up time the green light came on. So far so good.

    Great purchase

    It came exactly as shown on line so it fit in the precut hole. Instructions were very good. Unit fired up first try. Built solid.
