The unit shall incorporate an ionization smoke sensor with nominal sensitivity of 0.89%/ft. The temperature operating range shall be between 40˚F and 100˚F (4˚C and 38˚C) and the humidity operating range shall be 10% - 95% relative humidity, non-condensing. It shall be powered by 120VAC, 60Hz source with two AA battery backup. The combination smoke and carbon monoxide alarm shall be Kidde model KN-COSM-IBA or approved equal. Up to 24 Kidde devices (of which 18 can be initiating)Īrchitectural and Engineering Specifications If the unit malfunctions, the red LED will flash and the unit will chirp every 30 seconds.ġ20VAC, 60Hz 45mA max per alarm 2 AA battery backupġ0%-95% relative humidity, non-condensing Red LED - When a dangerous level of smoke or carbon monoxide is detected the red LED will flash. Flashes every 2 seconds while the alarm is in HUSH™ mode. Flashes once every 16 seconds to indicate smoke or CO previously detected. Flashes once per second during alarm to indicate initiating alarm. Flashes once every 60 seconds to indicate battery only mode. Green LED - Illuminates to indicate the unit is receiving AC power. Test Button Functions – Tests the unit for proper operation Ionization Sensor Technology - Ideal for detecting fast flaming and other types of fires. (Smoke must be present before Hush™ is activated) Hush™ Feature - Silences nuisance alarms for approximately 9 minutes. Peak Level Memory - Announces “CARBON MONOXIDE PREVIOUSLY DETECTED” if alarm has detected a CO level of 100ppm or higher since it was last reset. Works with existing smoke and combination smoke and CO mounting brackets. Smart Interconnect™- Interconnects up to 24 Kidde devices (of which 18 can be initiating).īattery Backup (2-AA batteries included) - Provides protection during power outages.įront Loading Battery Door - Replace the backup batteries without disconnecting from mounting bracketīattery Lockout System - The battery door will not close unless the batteries are properly installed.Īlarm Tamper Resist - Helps deter from tampering and theft.Īdjustable Mounting Bracket - Makes installation fast and easy. This constant communication enhances the alarm’s overall performance in all fires, and significantly reduces the potential for a nuisance alarm. Depending on what is detected, the alarm will adjust its smoke sensitivity in order to better discriminate between a real hazard and a false one. When either sensor notices a potential hazard, it will communicate with the other. Since carbon monoxide is present in all fires, having both detection chambers work together in one alarm is a breakthrough in the fire safety industry. The Intelligent sensor technology combines the detection capabilities of an ionization smoke sensor – which is more likely to detect smaller, less visible fire particles, like those produced by flaming fires – with that of an electrochemical sensor, which is used to detect CO. The Kidde KN-COSM-IBA,(21006377-N) uses breakthrough technology to offer a fast response to real fires, including smoldering and fast-flaming, as well as protect you from carbon monoxide and dramatically reduce the chance of nuisance alarms.
