PowerG Wireless Carbon Monoxide (CO) Detector
GSD-442 PG2 is a wireless Carbon Monoxide (CO) detector that gives early warning of CO poisoning danger, preventing damage to vital organs and even death. GSD-442 PG2 utilizes a sophisticated electrochemical sensor to provide linear output in proportion to CO gas concentration, which is the most accurate technology available for CO detection.
A sophisticated microprocessor receives data from a sensor, calculates the CO level and leak duration, and provides an alarm before dangerous CO levels are present. The detector has a five-year life and an expiration timer that notifies users when the detector should be replaced. As a battery-operated device, detection continues non-stop, even during power outages.
Based on Visonic's ground-breaking PowerG technology, GSD-442 PG2 combines several field-proven advanced technologies and the highly reliable AES encryption method. This combination of technologies delivers extended transmission range and battery life, and unmatched advantages for professional installers, central monitoring stations and end-users alike.
