Increase Customer Safety with Duct Smoke Detectors from Totaline®

Totaline 4-Wire Adjustable Mount Photoelectric Duct Smoke Detectors with System Sensor InnovairFlex technology combine an innovative collection of design enhancements and advancements to provide you with the flexibility you need to fit almost any application. Versatile, one unit can accommodate multiple installation footprints to overcome mounting constraints. The Totaline P270-3000PL and the P270-D4120W Duct Smoke Detectors are both UL-listed.

The Totaline P270-3000PL 4-wire photoelectric duct smoke detector features a pivoting housing that fits both square and rectangular footprints and mounts to round or rectangular ductwork. This unit senses smoke in the most challenging conditions, operating in airflow speeds of 100 to 4,000 feet per minute, temperatures of –4°F to 158°F, and a humidity range of 0 to 95 percent (non-condensing). A plug-in sensor head offers improved false alarm immunity and simple installation, testing, and maintenance. An improved cover design isolates the sensor head from the low-flow feature for simple maintenance.

The Totaline P270-D4120W watertight 4-wire photoelectric duct smoke detector is UL listed as a watertight enclosure providing protection against falling dirt, rain, windblown dust, splashing and hose directed water. D4120W duct smoke detector features a pivoting housing that fits various applications: both square and rectangular footprints mount to round or rectangular ductwork. This unit senses smoke in the most challenging conditions, operating in airflow speeds of 100 to 4,000 feet per minute, temperatures of –4°F to 158°F, and a humidity range of 0 to 95 percent (non-condensing). A plug-in sensor head offers superior false alarm immunity. These features, plus a NEMA 4 rating, allow operators to mount the detector to rooftop HVAC equipment or use the detector in other harsh environments.

Please remember; duct smoke detectors are not a substitute for open area smoke detectors; not a substitute for early warning detection; and not a replacement for a building’s regular fire detection system. However, these smoke detectors do help to enhance your customers’ home safety system when used in conjunction with other safety equipment such as the Kidde lineup of open area smoke and carbon monoxide detectors.
