Carbon Monoxide Detectors
Whether you have a “Basement Sentry
®
” Backup Pump System, or a competitive brand, all use batteries that give off gaseous by-products
when charging. Some of these by-products can produce a rotten egg odor. Also, some of these by-products can cause a CO detector to falsely
activate. In order to help prevent false activation, Zoeller Company recommends moving the battery as far apart from the CO detector as pos-
sible or, if necessary, vent the battery to the exterior. Zoeller Company provides the previous statements only as guidelines to help prevent
false activation of the CO detector. In no way are they meant to supersede the instructions that accompany the detector nor do they supersede
advice from the CO detector manufacturer.
If the audible alarm associated with your CO detector is activated, we recommend the following actions:
1) Take immediate action for personal safety as recommended in the CO detector literature.
2) Contact the appropriate agency to determine if the CO is being produced by your furnace, water heater, or any other device which uses
natural gas.
3) If you are certain that no CO is being produced, then a charging battery may be producing gaseous by-products which are causing the CO
detector to activate. Contact the manufacturer and ask for recommendations as to what can be done to prevent the alarm activation.
