System Sensor is pleased to announce the availability of the CO-REPL, a replacement CO cell for use with i4 Series COSMO-2W and COSMO-4W combination CO/smoke detectors. The i4 Series detectors are manufactured with a long-life carbon monoxide sensor that, over time, will lose sensitivity and need to be replaced.
The CO-REPL makes it easy and affordable to replace an end-of-life CO cell on an i4 Series detector without having to replace the entire unit.
Detector features
COSMO-2W and COSMO-4W detectors are equipped with a feature that will signal the fire alarm control panel once the CO sensor has passed the end of its’ useful life. This signal indicates that the CO sensor inside the detector must be replaced with the CO-REPL.
If left unresolved for 30 days, the detector will chirp intermittently. The typical lifespan of the CO-REPL is ten years from the date of manufacture. There is also a “Replace By” sticker located on the CO cell that will indicate the date on which the CO cell should be replaced.
