Carbon Monoxide (CO) is a toxic odorless, tasteless, colorless gas that ispresent whenever organic compounds are involved in combustion. Manyhomes utilize either propane, natural gas or wood for heat and cookingpurposes and the burning of these fuels produce CO. A malfunctioningappliance or flue will fill a space with this toxic gas completely unknownto the occupants.The Potter CO 12/24 utilizes the premium Carbon Monoxide (CO)detection technology for accurate detection and false alarm immunity.The CO 12/24 will only respond to the presence of CO and will not reactto other ordinary household chemicals that affect other detectors. Whenthe CO is detected, an 85 decibel sounder and the alarm relay activateto indicate the presence of CO. The sounder can be silenced for four (4)minutes by pushing the Reset button.The CO 12/24 operates on 0-28 VDC supplied by an intrusion or firesystem. The device emits a Temporal 4 pattern when the presence ofCO is detected. In addition to monitoring for tampering, the detectoralso monitors the sensor and detects if an internal problem exists. If afault occurs within the detector, the trouble/service a horn activates andthe trouble relay. This monitoring feature also complies with the sensorend-of-life requirement. The CO 12/24 has a 6 year warranty and lifespan. After 6 years, the detector needs to be replaced.
