Customer Reviews
I ordered and installed model GS886F combination Smoke/CO detectors throughout my home. Within four months, one of the units started chirping with a “battery low” announcement. I replaced the batteries multiple times, but… it continues chirping with a battery low warning.I visited the manufacturer’s support web site and submitted a request for help. it took some time to get a response, but… they did solve the problem:Press and briefly hold the center button three times in under two seconds. This will reset the device.
