The i4 Series is compatible with the i3 series, so an attractive CO monitoring solution can easily be retrofitted into existing i3 installations. The i4 Series CO cell can be easily replaced at end-of-life, resulting in a much lower life cost than having to replace the entire detector. Installers can pre-wire the i4 Series plug-in base, while a large wire entry port and in-line terminals provide ample room for neatly routing wiring. The base accommodates several back box options and also direct mounts using drywall anchors. The i4 head plugs into the base with a simple Stop-Drop N Lock action. When the CO cell reaches end of life, it can be easily replaced in the field without a tool. With the help of the module, the i4 Series detectors transmit distinct CO and smoke signals, allowing appropriate response from the central monitoring station. Intelligent features, such as drift compensation and smoothing algorithms, reduce nuisance alarms. The i4 Series LEDs enable instant inspection of detector status signaling normal\/standby condition, alarm condition, maintenance\/trouble condition or functional test mode. 2-wire devices allow loop testing via the EZ Walk feature where wiring can easily be verified by checking the LED status at each detector.

The i4 Series is compatible with the i3 series, so an attractive CO monitoring solution can easily be retrofitted into existing i3 installations. The i4 Series CO cell can be easily replaced at end-of-life, resulting in a much lower life cost than having to replace the entire detector. Installers can pre-wire the i4 Series plug-in base, while a large wire entry port and in-line terminals provide ample room for neatly routing wiring. The base accommodates several back box options and also direct mounts using drywall anchors. The i4 head plugs into the base with a simple Stop-Drop N Lock action. When the CO cell reaches end of life, it can be easily replaced in the field without a tool. With the help of the module, the i4 Series detectors transmit distinct CO and smoke signals, allowing appropriate response from the central monitoring station.

The design provides more wiring space with an added 3\/4 Inch conduit knockout. Numbers and labels for terminal designations are consistent with previous Innovair models. The new sampling tube can be clicked into position with one smooth motion from either the front or the back of the detector. The InnovairFlex D2 duct smoke detector has signals to indicate trouble and maintenance conditions. Additionally, a cover tamper feature is incorporated to indicate a trouble condition for a removed or improperly installed sensor cover. An improved cover design, with an integrated low-flow feature, isolates the sensor head from the low-flow technology for simple maintenance. The InnovairFlex series is designed for greater flexibility and reliable smoke detection to simplify installation and maintenance.
