- The Notifier D4120 & D4120W Photoelectric Duct Smoke Detectors feature a swivel housing suitable for different applications: both square and rectangular footprints and mounting to round or rectangular ducts. The multi-voltage 4-wire design allows the D4120 D4120W duct probe to be used as a 4-wire unit on a conventional fire detection system or as a standalone part of an HVAC system.
- These models sense smoke in the toughest conditions, operating at airflow speeds 0.5 to 20.32 meters per second, temperatures 20 to C to 70 °C, and a humidity range of 0 to 95% (non-condensing). Plug-in sensor heads improve false alarm immunity and simplify installation, testing and maintenance. Innovative cap design isolates the sensor head the low-flow feature for simple maintenance.
- InnovairFlex's housing provides ample wiring space, eliminates 20mm piping, and built-in short-circuit protection to prevent damage to sensitive components during installation. Specifying high contrast terminals makes wiring easy. Up to 50 detectors InnovairFlex can be connected. When one unit senses smoke, all connected detectors switch their relays; Only a smoke sensor will go the alarm, thus pinpointing the source of the fire.
- Easy-access Test/Reset button makes it possible to test the device with the lid on. Three DIP switches can be used to configure the field-selectable settings: masking the spoof delay, number of sensors controlled, and disabling the crash option.
- Each electrical panel has two LEDs that can be used to indicate the status of connected sensors, and a quick reference is printed on the cover explaining the LED status indicators (Standby, Maintenance, Failure). Incident and Alarm). Innovative chimney smoke detectors can be customized to meet local codes and specifications with no additional wiring required. The new InnovairFlex product line is compatible with all previous innovation models, including remote test accessories.
