® TrueAlarm Analog Sensing UL, ULC Listed; FM, CSFM, Addressable Duct Sensor Housings with TrueAlarm and MEA (NYC) Approved* Photoelectric Sensor, Available with Multiple Relay Control Features This device is a duct smoke housing. When provided with detector, it is designed to sample the air flow Compact air duct sensor housing with clear passing by it in the air duct to determine whether it contains unacceptable levels of smoke. The effectiveness of a duct smoke detector is highly dependent upon: the design and operating conditions of the air handling system in which it is installed, variables such as smoke dilution and stratification over which even the best designed systems have no control, and proper placement and positioning of the duct smoke detector, which is often compromised for practical reasons. For the reasons stated above, the effectiveness cover to monitor for the presence of smoke** of this duct smoke detector cannot be warranted or guaranteed. Under no circumstances should this duct smoke detector be used or regarded to be a substitute for the building’s Fire alarm and detection system to which this device is attached as a secondary detection device.
