This section contains the instructions for the end-of-life replacement of the 4098-9746 CO
Replacement Cartridge (CORC), in the CO SSD Bases (Carbon Monoxide Smoke Sensor and
Detector Bases). Replacement is necessary due to normal component degradation over time. It is
standard maintenance for the CO SSD Bases in order to prolong normal function without requiring
base replacement.
Note: During installation, you may be exposed to live circuits - attention required to ensure
personal safety and to avoid product damage.
